3D Logic

HIGHLY RECOMMENDED

http://www.microgames.info/game_info.php?products_id=205 (external link verified Nov-08)

Category: 3D abstract logic puzzle. Play online free of charge.

3D Logic is played on three faces of a cube. Each face is divided into a number of squares. Your objective is to create paths joining matching pairs of coloured squares, for example make one path which connects two red squares and another path which connects two blue squares. To do this, click on one of the squares at the end of a path, then click in a normal square to change it to that colour. Black squares cannot be changed. If you change a square by mistake, you can change it again later. Paths cannot cross, hence the difficulty of the puzzle. The early levels are very easy but the puzzle starts to get more difficult around level twelve. There are thirty levels.

3D Logic II

HIGHLY RECOMMENDED

A Tale Of Two Kingdoms

http://crystalshard.net (external link verified Jan-08)

Category: Adventure game. Download and install. Freeware.

Download file size: 96,486KB.

Creator/publisher: Crystal Shard.

This is a full adventure game available free of charge. The graphics are fairly low resolution but well done. Configuring the graphics filter and resolution settings is awkward and confusing but only needs to be done once. The game has a fantasy theme. At the start of the program the number of different characters and their relationships takes a while to comprehend. Nevertheless, this game is probably well worth persisting with.

This program has no connection with the similarly named classic "Twin Kingdom Valley" adventure game for the Commodore 64.

Alchemist's Apprentice, The (The Alchemist's Apprentice)

http://fizzlebot.com/gdc1/cgdc1.php?puzzleID=7 (external link verified Sep-06)

Category: Logic puzzle game. Play online free of charge.

The alchemist has left you with a letter asking you to make three items, a book describing the available ingredients, and a recipe book. You have to mix the ingredients together to make the required items, puzzling out the logic behind the system.

Amazong

http://jenslieberum.de/amazong/amazong.html (external link verified May-06)

Category: Abstract board game. Play online free of charge.

Amazong is a Java applet which plays the game of Amazon, which combines elements of chess and go. Amazong will run on most computers.

Ambivalence

http://www.fongeboon.jp/game/ambivalence.html (external link verified Jan-08)

Category: Mysterious mechanism puzzle. Play online free of charge.

Ambivalence is very similar to many of the mysterious mechanism puzzles in Myst and its sequels. You are presented with a locked door, on each face of which are various devices. Your task is to unlock the door. What makes the game unique is that you can work from both sides of the door, switching readily between the two whenever you wish. Although the web site on which this program appears is in Japanese, this isn't a problem for non-Japanese speakers.

Armadillo Run

http://armadillorun.com (external link verified May-06)

Category: Simulation puzzle. Download and install; freeware demo version; payware full version.

Download file size (demo): 935KB.

Armadillo Run is a simulation puzzle game in which you have to create structures to guide a basketball to a destination. The structures are built using materials such as ropes, metal girders, sections of cloth and metal plates. Each structure can be tested and modified. Each level can be solved in a variety of different ways. The free demo version of the program only includes a few easily solved tutorial and introductory levels.

Armor Picross

http://www.armorgames.com/games/armorpicross.html (external link verified Dec-07)

Category: Nonogram (picross) puzzles. Play online free of charge.

The nonogram puzzle concept originated in Japan. "Picross" is one alternative name, others include "griddlers". You are presented with a square grid of cells and need to discover which cells should be coloured in. There are clues which tell you about the groups of adjacent cells in each row and column, for example 3 5 means a group of three, then a gap of at least one blank cell, then a group of five. There are quite a few computer implementations available, all of which fall down in one area or another (awkward user interface, failure to present puzzles in any order, failure to record your progress, unwanted gimmicks such as time limits, etc). This is one of the better versions but you may wish to search for others and try them as well.

Assembler

HIGHLY RECOMMENDED

http://www.kongregate.com/games/BryceSummer/assembler (external link verified Nov-08)

Category: Physics-based 2D puzzles. Play online free of charge.

This is a block-moving game, but completely different to Sokoban. You view the scene side-on and have to move one or more green shapes so as to be inside the green outline shapes. Blocks, planks and other devices fall and swing under gravity. If you accidentally hit one object while moving another it will move but in most cases this will only happen if you are careless. There are also some fixed obstacles which need to be worked around.


B

Babala

HIGHLY RECOMMENDED

http://www.babala.org (external link verified Oct-06)

Category: 2D turn based puzzle game. Download and install; freeware.

Download file size: program 486KB; required GTK+ 2 runtime 4993KB.

Creator: Pavel Richter.

Babala shares some design concepts with DROD but is sufficiently different to be well worth exploring. On each turn you have a number of moves, each of which can be used to move or to fire a missile at the opposition. Unlike in DROD, turns can be made freely. The game has at least ninety levels.

Technical note: be sure to also install the GTK+ 2 Runtime Environment as explained on the Babala downloading and installation web page.

BamBoom

http://www.newgrounds.com/portal/view/360432 (external link verified Dec-07)

Category: Abstract maze puzzle. Play online free of charge.

Navigate one, two, three or more coloured circles around a maze, each to a square of its own colour. You can move either the red circle alone, or the red circle and the yellow circle, or the red circle and the yellow circle and the green circle (and so on for more colours). However, you cannot move the yellow circle without also moving the red circle, nor can you move the green circle without also moving both the red and yellow circles - which where it starts to become difficult. This is a clever and original idea, although it bears some resemblence to the mimic rooms in DROD. The game has well designed controls to adjust the brightness of the playing board and the choice and volume of background music.

Beltway

http://www.kongregate.com/games/StrangerStudios/the-beltway (external link verified Oct-06)

Category: 2D board game (played against the computer). Play online free of charge.

A variation on the Chinese Checkers concept, with intersecting paths of different colours, meant as an abstract representation of the road system around Washington, DC. Pieces can move as far as desired along a path, but changing to a different path requires a second move. Except for the very first move, players make two moves at a time. There are various combinations of game options offered. The program doesn't make the computer's moves very obvious to see.

Blackshift

http://www.foon.co.uk/blackshift (external link verified May-06)

Category: 2D puzzle game. Download and install; freeware.

Download file size: 2894KB.

Blackshift is a 2D overhead view/square grid puzzle game, somewhat similar in concept to Chip's Challenge. I have only just started to explore the program but so far it appears to be promising, although higher levels require fast reactions. Game features include being able to pick up one object at a time and then moving it or using it.

Bloc

http://www.onlineflashgames.org/10-puzzle-games/2823-flash-game-bloc/play.html (external link verified Nov-07)

Category: Sokoban variant. Play online free of charge.

Push blocks of same colour next to each other, so they destroy themselves. Also make sure you don't block your exit path. An interesting new variation of a classic puzzle game.

Blockoban

http://www.bonuslevel.org/games/game_4.html (external link verified Apr-08)

Category: 2D abstact puzzle. Play online free of charge.

Slide coloured blocks to destinations of the same colour. The difficulty lies in making the blocks stop at the correct places. Users can create additional levels for this game.

Blockout

http://www.onlineflashgames.org/10-puzzle-games/3032-flash-game-blockout/play.html (external link verified Nov-07)

Category: 2D abstact puzzle. Play online free of charge.

A variant on the "tilt mazes" concept. Guide a block to its destination. Once set in motion the block will continue to move until it is blocked by an obstacle. Fifty levels. The presentation is somewhat sparse, but adequate.

Bloxorz

HIGHLY RECOMMENDED

http://www.albinoblacksheep.com/games/bloxorz (external link verified Nov-08)

Category: 3D abstract maze puzzle. Play online free of charge.

On each level you have to rotate a 2 x 1 x 1 block around a path which is effectively a maze. There are additional features such as buttons and bridges which make your task trickier. A simple idea (although some of the puzzles are difficult), very nicely presented.

Blueprint

http://www.teagames.com/games/blueprint/play.php (external link verified Jul-06)

Category: 2D machine building puzzle. Play online free of charge.

Creator/publisher: Teagames.

This puzzle game has a similar concept to the classic "Incredible Machine". You have to place objects such as ramps, tubes, funnels, conveyor belts and bumpers so as to guide a ball to a target. There are twenty-eight levels.

Bobitos

http://www.cin.ufpe.br/~dfs2/jogos/AI.swf (external link to SWF file verified Jul-06)

Category: 3D abstract logic puzzle. Play online free of charge.

The Bobitos are trapped on a 2D grid. When told to move, they continue to do so in a straight line until they are stopped by another Bobito, or fall off the edge of the grid. Your task on each level is to guide the king Bobito to the central square. Although the game is presented in 3D, this doesn't adversely affect visibility.

Bound Around

http://www.blueskied.com (external link verified May-06)

Category: Platform game. Download and install; payware with freeware demo version.

Download file size (demo): 2000KB.

Creator/publisher: Blueskied Games.

This is the most complex of the three games in Blueskied Games' "Bound" series. You control a ball which can be made to change colour by hitting coloured circles. Your objective is to hit coloured squares so as to destroy them all. Complicating factors include skull squares which are fatal if hit, and an inability to change your vertical direction except by bouncing off squares. The freeware demo version only provided access to the first few levels. The complete game is payware.

http://www.deviantart.com/view/17306068 (external link verified Jan-07)

Category: Logic puzzles. Play online free of charge. The Shockwave Flash animation SWF file can also be downloaded and played offline.

Slide the blocks left or right so as to make the golden ball drop, while preventing the silver balls from doing so. Unfortunately the game currently only has five levels, none of which are very difficult. The main challenge is to complete each level in the smallest possible number of moves. With more levels and more blocks the idea has considerable merit.

Cut chains to release balls and make them fall, roll or bounce into containers which matching colours. This game mainly involves figuring out what to do, but some levels also have a fairly precise timing element to them.

Click Drag Type

HIGHLY RECOMMENDED

http://fizzlebot.com/cdt3.php (external link verified Nov-08)

Category: Assorted logical puzzles. Play online free of charge.

Creator: Simple Andy.

A collection of fifteen very varied and highly original visual and audio puzzles, many of which are excellent. However, most of the latest set (puzzles 11-15) are far too vague and overcomplicated in my opinion.

ClickMazes

Andrea Gilbert's personal site has a cornucopia of wonderful original puzzles. The Plank Puzzles are especially excellent.

Cobacoli

http://jayisgames.com/games/cobacoli (external link verified Feb-08)

Category: A billiards/pool/snooker variant. Play online free of charge.

Creator: Tonypa.

On each of the very varied levels, shoot the white ball so as to direct each of the coloured balls to a line of the same colour. You have control over the angle of the white ball but not the power of the shot, nor can you put on "side", etc. The white ball can bounce off white lines without penalty, but if it hits a coloured line you lose one of your available shots. Since the game has no realtime element as regards its controls, and considerable thought is required in making each shot, in my opinion it does qualify as a puzzle.

Codex Of Alchemical Engineering, The (The Codex Of Alchemical Engineering)

Position positive, negative and neutral particles, then click the Play button to make them fall, roll and bounce under gravity. The aim is make positive and negative particles collide and destroy each other. While the concept has considerable merit, very precise positioning is often required and the graphics are unattractive.

Colony

Category: Board game. Download and install; payware with freeware restricted demo version.

Download file size (demo): 6032KB.

Creator/publisher: Midnight Synergy

Colony is a multi-player board game where the user plays against the program, which can control one or more opponents. The rules of the game are simple but gameplay sufficiently complicated to be interesting. A particularly attractive feature of the program is that each level is played on a different design of board. Unfortunately the program's 3D design makes operation somewhat difficult. The version which can be downloaded free of charge is a restricted demo.

Crossblock

Remove all the blocks by drawing a horizontal or vertical line through a specified number of them at a time. The first fifteen or so levels are extremely easy, then it starts to get much more interesting.

Cube-It

Category: 2D abstract puzzle. Play online free of charge.

Navigate a block around a path so as to destroy all the red tiles and end on a white tile. The red tiles destroy themselves as you step off them. There are a few other types of tiles, such as directional conveyor belts. The game is presented in an isometric viewpoint but this doesn't interfere with the movement controls or visibility, except that on the larger levels not all of the level is visible at the same time.

Cubrius

http://www.cubrius.com (external link verified May-06)

Category: Sokoban variant. Play online, or download and install. Freeware restricted demo version; payware full version.

Download file size (demo): 5277KB.

Cubrius is a Sokoban-like game. However, instead of having to move the blocks to specific locations, in Cubrius you have to move blocks of the same colour so as to make them touch each other, which causes their destruction. On each level all the blocks must be destroyed.

The game suffers from several complications. It has an unnecessary 3D implementation which makes the positions of the blocks and gaps difficult to see at times. The man only moves a fraction of a square at a time, for no reason that I can see. The initial levels have rather too many different types of special blocks which might have been better left for the more advanced levels. Nevertheless, the idea of the game has considerable merit and the program is well worth investigating.

On one occasion the Spyware Doctor program prevented the downloaded version of Cubruis from installing a system-wide keylogger on my computer. This might have been a false positive, or a genuine matter of concern. Bazooka, Grisoft AVG, Lavasoft Ad-Aware, PestPatrol, SpyBot Search And Destroy and Windows Defender do not report any malicious element to this program. In explicit scans of the program's target folder (C:\Program Files\Cubrius, which contains one file called CubriusTrial.exe), Microsoft Malcious Software Removal Tool and Spyware Doctor do not report finding anything malicious.

D-Blocks

http://www.kongregate.com/games/Mike/d-blocks (external link verified Oct-08)

Category: 2D abstract puzzle. Play online free of charge.

You are presented with a set of blocks, each with arrows on them pointing up, down, left or right. On each turn, you can remove all the blocks in a row of your choice that point left, or all those which point right, or all the blocks in a column of your choice which point up, or those which point down. This is done in a very simple manner that is easy to understand and use. Any blocks above a removed block will fall down to occupy the space. Your objective is to remove all the blocks with a very limited number of turns. This is an original and elegant idea which makes for some tricky puzzles.

D-Star

http://lightforce.freestuff.gr/dstar.php (external link verified May-08)

Category: 2D maze puzzle. Play online free of charge.

Creator/publisher: LightForce Games.

Collect all the yellow diamonds. Each time you select a direction you will keep moving until you hit a wall but you can swap places with a special blue diamond whenever you wish. This swapping is the key to solving the puzzles. The concept of this game was originally devised by Joe Wingbermuehle.

Dave The Worm

Category: 2D machine building puzzle. Play online free of charge.

Place special blocks of various types so as to modify Dave's behaviour and guide him to his destination on each level. The game can be played online or downloaded, but the downloaded version requires players to be online while playing in order to obtain each level. Each time you fail a level, you need to manually replace all your blocks into position (with whatever modifications you wish to try) before re-running, which appears to be a serious design limitation. It is however possible to use the Pause button and add or remove blocks before continuing. The built-in editor option may also provide a means of saving your progress part-way through a level. A key concept, and one unique to this game, is that additional blocks may need to be added once the worm has been set in motion. This is done by using the Pause button.

Place one or more balls so that when they fall they will destroy all the Bodteds. This game has eighteen extremely varied levels.

Category: 2D polyomino puzzle. Play online free of charge.

Move, rotate and reflect polyominoes (Tetris pieces) on a board so as to reveal some special squares.

This game is sponsored by a web hosting company and an advertisement for their services appears initially before the game loads.

The game's menu and instructions suffer from a poor choice of colour scheme, making them very difficult to read. The menu options become much brighter when the mouse is drifted over them but the instructions do not. The instructions are as follows: The goal of Digit Puzzle is to reveal the hidden treasure box, which occupies a number of contiguous special squares on the board. To pick up a piece, left-click it. To drop a piece, move it over empty squares and the left-click it. To rotate a piece, pick it up and move it so that it is partially or totally over occupied squares and then left-click it. To reflect (flip) a piece, pick it up and then press the "cursor up" key.

Doggnation

Category: 2D logic puzzle. Play online free of charge.

Creator: Bart Bonte

The doggs (with two g's) want to increase the size of their castle. To do that, they need to carry coloured blocks to the castle. However, at each stage of the building work, only the correct combinations of blocks can be used. There are static doggs who offer stacks of coloured blocks, and moving doggs who walk past them on their way to the castle. Each of the static doggs can be clicked so as to alternately face forwards or backwards. A moving dogg will take the top block off each static dogg's pile, provided the static dogg has at least one block, and the static dogg is facing forwards. If a moving dogg does takes a block, it goes on the top of their pile. Once you start the doggs moving, you must click the static doggs so as to achieve the desired results. Therefore you need to carefully plan your actions, then actually implement them in real time.

This is an original idea and a clever puzzle. However, for some reason it lacks something in terms of playability.

DROD (Deadly Rooms Of Death) - Architect's Edition/King Dugan's Dungeon

HIGHLY RECOMMENDED

http://forum.caravelgames.com/downloads.php (external link verified Sep-08)

Category: 2D turn based puzzle game. Download and install; freeware.

Download file size: 12.6MB.

Don't be put off by the name. DROD is not a violent shoot 'em up. It is a 100% puzzle game, and a first class one, with no realtime element.

DROD is played on a 2D grid of square cells which is viewed from above. You play the part of Beethro Budkin, whose mission is to clear a dungeon of monsters of various types, room by room and level by level.

Beethro is armed only with a sword. His only possible actions are to move one square at a time up, down, left, right or diagonally; or to turn so as to swing his sword through 45 degrees at a time clockwise or anticlockwise. Beethro's movements are controlled by the keyboard. On an alternating basis Beethro makes a move (controlled by you) and then all the surviving monsters in the room move in reaction (controlled by the program). All the different types of monsters move in various predictable ways. You can plan and consider each of Beethro's moves for as long as you wish.

That might appear to be a very sparse game structure but perhaps the word "elegant" would be far more appropriate. The variety of behaviours of the different types of monsters and the game's other features, coupled with the incredible creativity of the level designers, make for a superbly magnificant and very highly addictive puzzle game. As one example, many rooms feature doors which are controlled by orbs. Hitting an orb with your sword might open some doors, close other doors, and toggle the states of yet more doors. As another example, in some rooms you have to manouvre one set of monsters in order to defeat a different set of monsters.

On restarting the game, you continue from where you left off. You can also restart any room. You can even restart from checkpoints within a room, which are conveniently placed in lengthy or particularly tricky chambers. There is also a facility to restart from any previously visited room. The game allows for numerous separate players, each of whom's progress is recorded independently. Only one person can play the game at a time.

In addition, numerous additional user-created puzzle collections (or "holds" to use the correct term) are available.

The game publisher's web site has a free forum called CaravelNet, a free hints facility which is integrated into the forum, and a payware subscription online gaming facility for DROD which very confusingly is also called CaravelNet.

Smitemaster Selections (SS) are puzzle collection which are only available to the CaravelNet online gaming system's subscribers or in the form of payware mail order CD's.

The Architect's Edition version of DROD includes the entire twenty-five levels of the original version of King Dugan's Dungeon (KDD), plus the ability to import additional downloaded dungeons, and also a level editor in which you can build your own dungeons (hence the name). Architect's Edition is the best version for beginners to DROD.

Download file size: demo 40.7MB, full version 102MB.

This version continues the story begun in Journey To Rooted Hold. This version suffers from several serious drawbacks at the start, which may cause those who sample the free demo to reject it. Near the start there are some very weak attempts at humour and a large superfluous area which contains no puzzles. There are also some very difficult puzzles early in the game, and a lack of stairs between some levels which makes it very easy to accidentally skip the level title screens that sometimes contain useful information. However, after leaving the initial area this version of DROD contains some wonderful puzzles, mainly based on new game elements. The demo gives a misleadingly poor impression of the game as a whole.

Dyson's Telescope Game

http://www.dyson.co.uk/game (external link verified May-06)

Category: Abstract puzzle. Play online free of charge.

This is an innovative puzzle, implemented as a set of Shockwave Flash animations. Each Shockwave file contains a separate set of levels. On each level you have to use expanding and contracting telescopes to push and pull balls into holes.

The game can be played online, or the Shockwave SWF files can be downloaded for use offline (their locations are obvious if you look at the web page source files). Additionally, an EXE version of the first fifteen levels can be downloaded, but this is only a shell which actually runs a Shockwave animation.

Each Shockwave file automatically records which levels in its set have been solved. To erase this record, so as to be able to completed levels again, delete the appropriate .sol file in C:\Windows\Application Data\Macromedia\Flash Player\... (this location is correct for Windows 95 but many differ in other versions of Windows). Each .sol file, which is tiny, will be automatically recreated next time you play that set of levels.

At present there are four sets of levels: First 15, More (16-25), Transporter and Grand Master. First 15 are all very simple, the other sets more taxing. The web site says more levels may be made available in the future.

Eets

http://www.eetsgame.com (external link verified Jul-06)

Category: Platform-strategy-puzzle. Download and install; freeware demo version; payware full version.

Download file size (demo): 22MB.

Creator/publisher: Klei Entertainment.

In this platform game you must move various objects into position and then start the character moving. As the character encounters each object, the behaviour of the character is modified so as to cause it to jump small distances at the end of platforms, jump large distances, or reverse direction, etc. In addition, some realtime interaction is required once the character starts to move. On each level the character must pass over a featureless jigsaw puzzle piece.

Eets is a clever idea and has received some excellent reviews. However, I found the cartoon graphics annoyingly childish and the effect of the various types of objects is frustratingly not obvious from their visual appearance on the screen.

The free demo version involves a 22MB download and only allows for a hour's playing time before it expires.

This is a completely different program to the classic Entombed game created by Ultimate for the Commodore 64.

This is a graphical adventure game, somewhat similar to Myst in concept. While exploring archaeological ruins in Turkey, you fall through a hole into a series of underground chambers. Each chamber contains one or more puzzling mechanisms. Your objective is to escape, which involves exploring the chambers and their mechanisms.

This game is somewhat similar to Myst. It would appear to be considerably larger and more complex than would appear at first.

When installing the program, accept all the defaults. Do not attempt to change the name that the game is registered to. Do not attempt to change the target folder from C:\Entombed. After installation, do not attempt to move the target folder from C:\Entombed. However, it is vital to change the compatibility properties of C:\Entombed\ENTOMBED.EXE so that "Run in 256 colours" is ticked. Manually create any desired shortcuts to C:\Entombed\ENTOMBED.EXE.

The game consists of helping two fish - one large and one small - escape from each level. In order to succeed to two fish must co-operate by pushing and supporting various objects. The game bears some resemblence to Sokoban, but here the objects are of different sizes, gravity makes unsupported objects fall, and the objective differs. There is no real-time element - you can consider each move for as long as you wish.

There are four different types of shapes (squares, circles, crosses and triangles) each of which can be pushed onto the board from each side, but only into alternately rows (or columns). This is an original idea, nicely implemented, but the instructions are in Japanese and the puzzles are difficult.

Fitznik is a Sokoban variant, involving not only pushing blocks but also collecting keys and gems, plus avoiding snakes and spiders. The free demo version allows access to the first nine of the game's 63 levels. All nine of the demo levels are fairly easy. On my computer the program failed to run on the first attempt after installation but worked on the second and subsequent attempts. The game has semi-3D graphics where pure 2D graphics would have been preferable, and there is a fair amount of irrelevant distracting and confusing clutter on the gameboard. However, the idea has merit, especially if the payware levels offer more of a challenge than the demo levels.

Fugashu

http://www.kongregate.com/games/Trentish/fugashu (external link verified Feb-08)

Category: 2D board game puzzle. Play online free of charge.

Fugashu is an unusual and as far as I know original puzzle. A rectangular board is divided into cells, and initially there are numbers in each cell. The numbers can be moved to adjacent cells so as to build up continuous runs. For example: 3 can be moved to 4 so as to create a 3-4 run; 3-4 can be moved to 5-6 to create a 3-6 run; 2 can be moved to 3-6 to form a 2-6 run; 2-6 can be moved to 1 to form a 1-6 run. When a run is complete it is removed from the board. The objective is to remove all the numbers from the board. A new number chosen at random can be dealt into any blank cell and this is often required. There are also a number of special cards which add yet more complications, but thankfully there is an option to disable their use. Careful study of the in-game instructions is vital, and the game is far from simple, but it probably rewards those who persevere with it. The pleasant and peaceful Japanese flute background music helps players to relax.

This excellent program has elements of the traditional English pub game shove ha'penny, and snooker. The objectives, the rules and the behaviours of the game's objects are all fairly simple and perhaps best discovered by exploration rather than being explained here. The game is difficult with a score of only ten being considered very good, but it is highly addictive. There is a real-time element but this does not detract from the puzzling aspect. Deciding on the best strategy is not always a simple decision.

Category: Sokoban variant. Play online free of charge.

Push the blocks out of your way and collect all the globules of slime. Blocks can be removed from the board by pushing them down chutes. The slime forms a snake which increases in length behind you, but it can be pulled in the opposite direction by moving to its tail. Once complete, the slime snake must be disposed of by taking it to a suction vent, but each vent can only be used once. One-way arrow squares further complicate the puzzle.

This is a nice idea. One major criticism: the depiction of the boxes is in semi-3D, making it very difficult to see which squares they block. A straightforward overhead 2D design would be far preferable.

The levels start to become difficult very quickly.

Category: 3D technical drawing puzzle. Play online free of charge.

On each level you are presented with the plan and elevations of a 3D object made out of cube-shaped blocks. You have to create the object in 3D so as to match. The problem is that you are only allowed to use a specified number of blocks. This is a superb idea and very nicely implemented but I do wish there were a few easy levels to get you started.

This puzzle, by the same author as "Click Drag Type", has no instructions. You're not even told what you're trying to achieve. The puzzle has some similarities to the interconnections of computer logic gates so as to form arithmetic units.

Ice Breaker

Category: 2D puzzle. Play online free of charge.

A group of Vikings are trapped in blocks of ice. You have to cut the ice by dragging with the mouse, so as to free each trapped Viking and make him drop into the longboat. Later levels feature swinging blocks of ice and ropes. There is quite a long delay as level is set up. Scrolling around the area of each level is somewhat awkward and the game would benefit by using a much larger stage area.

The objective on each level is to place bombs and other objects into positions where they influence the path of a ball as it falls under gravity, so as to direct the ball to hit a target. The objects include bombs of various kinds and teleports. In addition the ball's path may be influenced by fields of various types, over which the player has no control. After placing the bombs (etc) the simulation is started, the path of the ball observed, the simulation stopped, the objects' positions adjusted and so on in a cycle until success is achieved. The positions of the bombs usually need to be very precise. In addition, on many levels the bombs also have to be detonated at precisely the correct moment. Some players may therefore feel that the game is too fiddly and over-complicated.

In The Dog House

http://www.nitrome.com/games/doghouse (external link verified Sep-08)

Category: 2D sliding blocks puzzle, with additional complications. Play online free of charge.

You are presented with a sideways view of a house, divided into blocks. The rooms, stairs and some other features can be moved or rotated. By this means, a dog must be persuaded to move to the kitchen. Some blocks cannot be moved, some can only be rotated, some can only be slid horizontally or vertically, and some can be slid both horizontally and vertically. The design of the wallpaper on each block indicates its possible movements, possibly not always accurately (this might be due to a bug, or an as yet not understood game feature). The game has some behaviours which are not obvious, such as a pair of doors in unconnected areas of the house acting as a portal. Finally, some of the movable background tiles are difficult to distinguish if you have your monitor brightness/contrast/gamma turned down low.

Category: Abstract 2D game. Play online free of charge.

Life is a cellular automation process devised by John Horton Conway, in which the birth, survival and death of each of the pieces on a two dimensional board is determined by the number of neighbours each piece has. In this game you have to place additional pieces in the starting position for Life, in order to achieve an objective in a certain number of generations, for example having at least three pieces still alive after ten generations. The game explains the principle well and implements it effectively, but after the first few levels the puzzles become very difficult.

Category: Abstract 2D puzzle. Play online free of charge.

This is a highly innovative puzzle idea. On each level you have to move blocks so as to make blocks of the same colour join together, the unusual feature being that all the blocks move at the same time, subject to immovable obstructions. The early easy levels are perhaps too numerous but around the mid-twenties things start to become more challenging.

Jelly Fusion

http://mirror2.cgdc2.fizzlebot.com/?puzzleID=13 (external link verified Apr-07)

Category: Abstract 2D puzzle. Play online free of charge.

A number of blobs are located in some of the cells of a rectangular grid. You objective is to move the required number of blobs to a special target cell. You can drag blobs to other cells, subject to some unstated rules which you must discover yourself. This is a nice idea but it might benefit considerably by the addition of a clear statement of the rules. Without that, many potential players will probably abandon the program in frustration. In addition, level 1 is trivially simple while level 2 is by far the most difficult.

Here is a tentative attempt to list the rules, which might not be entirely correct. Additional complications are introduced in later levels but these are mainly obvious. Because some people may wish to discover the following information by themselves, the text is hidden. To read it, drag your mouse over it so as to select it.

Blobs can only be dragged to an orthogonally adjacent cell, i.e. a cell above it, below it, to the left of it, or to the right of it (no diagonals).

A blob with one eye cannot be dragged to an empty cell.

A blob with one eye can be dragged to an occupied cell and it then adds to the number of eyes in the destination cell.

A blob with more than one eye can be dragged to any adjacent cell. It will leave a one-eyed blob in its original location, and its other eyes will add to the number of eyes in the destination cell.

The number of eyes in any cell cannot exceed the maximum displayed for each level, except for the target cell on the final winning move of the level. Until the final winning move, the number of eyes in the target cell is subject to the limit.

Blobs can be moved out of the target cell as well as into it, subject to the above rules. This far from obvious rule is vital to the solution of some levels.

Category: Programming puzzle. Play online free of charge.

Create a program which directs the movements of a robot. The robot has to move, turn, jump up and down steps, and light up certain squares. The program is "written" by dragging command icons into a section of the screen. No typing is required. There is only room for a restricted number of commands, forcing the use of functions (i.e. subroutines). This critical factor makes for some good but difficult puzzles, but there is a need for considerable more explanation for non-programmers.

Create a function (subroutine) of commands by dragging command icons into the f1 or f2 area. Then to obey the function from the main program, drag the f1 or f2 command icon into the main program. Each function can be obeyed as many times as desired, for example f1-f1-f1. In addition, it is possible to obey one function from inside the other function, for example f1 could contain the f2 command icon, any number of times.

Besides being a clever idea for a puzzle, this game gives some insight into programming, especially the early days of computing where every effort had to be made to keep programs as short as possible.

On a rectangular grid there are squares of various colours, plus a number of special squares with a snowflake design. Your objective is to destroy all the snowflake squares. This is done by making all the squares between two snowflakes the same colour by swapping orthoganally adjacent squares . However, there is a significant complication: if the number of squares between two snowflakes is even they and the squares between them are destroyed, but if the number of squares is odd then in addition a new snowflake is created at the mid-point. Any squares above destroyed squares will fall downwards. The game starts with quite a large number of very simple tutorial levels.

Pentominoes are shapes which can be made by fitting five squares together. They are the shapes used in Tetris. In Pentalogic the pentominoes have to be placed inside a shape so as to fit exactly with no gaps and no pentominoes overlapping. A pentomino can be moved by dragging a point anywhere inside it, rotated by dragging its border, and reflected by double-clicking it. This forms a slightly awkward control system but the puzzles are good.

Pittoch

http://www5e.biglobe.ne.jp/~anhr/download/pittoch100.lzh (external link verified Aug-08)

Category: 2D abstract puzzle. Download and install free of charge

At first sight Pittoch may appear to be a standard platform game but it is in fact an innovative puzzle game.

You have to move up, down, left and right to collect keys, then make your way to the exit. However, you need connect player icons together, as each of them can only carry one key. Player icons can be connected vertically and horizontally. Some of the gaps in the platform structure have a restricted width or height, making route planning vital.

In addition, some levels have "cloud" icons which can be moved up and down, and which also connect together. The ability to control the upward and downward movement of clouds depends on their number of connected icons and the number of connected player icons, in a way that I have not yet fully determined. If it can be moved upwards, a cloud allows you to rise up further than the normal two square jump limit.

The game is distributed as an lzh file. This is similar to concept to a zip archive but you may need a special program to extract the contents. I used WinRAR without any problems. When extracted, the resulting exe and chm files can be copied into a folder in C:\Program Files and shortcuts created manually. There is no automated installation routine.

Keyboard controls: select a menu option with the cursor keys, invoke a selected menu option by pressing the Return key, move your player icon(s) with the cursor keys, jump with the space bar (and cursor left or right if desired), reset a level with the R key, exit with the Esc key.

This is a clever idea, well presented within the game itself. However, a proper installation routine and some better instructions would make it even more attactive.

Expand the diamond shapes so as to connect them all together. A diamond cannot be expanded more than three times, nor can it be expanded twice in successive moves, nor can it overlap with another diamond. This is a clever idea but a very difficult puzzle.

This game has no instructions. It's fairly obvious what to do after some experimenting, and as discovering this is part of the pleasure I won't go into details here except to mention that rapid simple mental arithmetic is required. An excellent implementation of a simple but effective idea, with some very nice musical chimes as special effects.

A rectangular framework contains a number of coloured square tiles. Each row and each column of tiles can be rotated, rows leftwards or rightwards, columns upwards or downwards. The objective is to make all the tiles in each row the same colour.

This is a good game, well programmed, but even the initial levels are very challenging.

Popcap Games

A commercial site. Most Popcap games are in the form of Java applets which can be played online on most computers, but a few are conventional Windows EXE programs which can be downloaded. In some cases charges are made for the full feature EXE versions. People looking for puzzles will probably like Mummy Maze.

Portal

Move around various chambers, in each case attempting to reach the exit. When your path is blocked by obstacles, you can fire a gun to open two portals. As you enter one portal you will exit from the other portal. The position at which each portal is created is not the current mouse pointer position, but the nearest solid surface in line with where your gun is pointing. Portals can be opened on walls, floors and ceilings but only in places you can fire at with the gun from your current position. If a portal is created at an undesired position, firing the gun again will open it elsewhere. Operation is more than somewhat awkward and takes quite a while to learn but this is a puzzle game probably worth persisting with.

Pozzo - Jello Crusade

Category: Abstract 2D puzzle. Download and install. Freeware.

Pozzo involves traversing a maze in order to eat all the jello. Once a jello square has been visited, it cannot be visited again (i.e. jello squares act in the same way as trapdoors in DROD). Some squares act as keys which unlock doors (i.e. the equivalent of orbs in DROD). Later levels probably have additional features. Despite its similarity with the DROD trapdoor rooms, this game is probably worth exploring.

There is no automatic installation procedure. Extract the contents of the downloaded ZIP file into a folder, move that folder to C:\Program Files and create any desired shortcuts. There is also an alternative EXE download file version from other sources which has an automated installation procedure but the installed program then fails with an error on my computer. The ZIP file version seems to work without any problems.

Use the cursor keys to move. Press R to restart a level. Pressing F4 toggles between windowed and full screen. Pressing G toggles the grid lines on and off. I haven't found any method of disabling the music.

Route energy to all the pyramids, without running out of energy. Most levels are fairly easy. This puzzle has an isometric view but for once this is not a serious drawback.

An original game but somewhat in the style of Chip's Challenge, DROD and Sokoban, having a 2D overhead view. You have to discover a path through a maze of revolving doors and blocks which can be pushed. On some levels you have to control two independent copies of your character. There are three sets of levels, easy, medium and hard. The game has no realtime element and levels can be restarted without penalty. A clever idea, with good progressive level design and nicely programmed.

Puzzle Pegs

Category: Abstract 2D puzzle. Play online free of charge.

Push shapes ("pegs") of various designs around a 2D board with the aim of destroying them all. Pegs can be destroyed in two ways - by pushing them into a trap square, or by pushing two pegs of the same type together. The different types of pegs have different behaviours, for example one type changes into a fixed obstacle square when two of them are combined together, while another type changes into a normal square when it is pushed over a trap. An enjoyable game.
