3D Logic

HIGHLY RECOMMENDED

http://www.microgames.info/game_info.php?products_id=205 (external link verified Oct-06)

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

http://3d.logic.fizzlebot.com/ (external link verified Nov-07)

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

A sequel to the original 3D Logic program.

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.

Ankh

Category: Linked web page riddle game. Play online free of charge.

To move on to each new web page, figure out the URL from the available clues. This game is not related in any way to the classic Commodore 64 game of the same name.

Antiriddle

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 Games

Category: Various games including some puzzles. Play online free of charge.

Armor Picross

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

Category: Nonograms (abstract 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.

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.

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 Jun-07)

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.

Click Drag Type

HIGHLY RECOMMENDED

http://fizzlebot.com/cdt3.php (external link verified Oct-06)

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

HIGHLY RECOMMENDED

http://www.clickmazes.com (external link verified Oct-06)

Category: Abstract puzzles. Play online free of charge.

Andrea Gilbert's personal site has a cornucopia of wonderful original puzzles:

To the best of my knowledge none of the puzzles have any real-time element. "Oskar" is Oskar Van Deventer, the famous Dutch puzzle inventor.

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.

Colony

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

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

Download file size (demo): 6032KB.

Creator/publisher: Midnight Synergy

Colony is a two-player board game where the user plays against the program. 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 difficult. I suspect that the version which can be downloaded free of charge may be a restricted demo.

Color Box (Colour Box)

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

Remove all the circles by clicking each one in turn. Each circle you click must share a colour with the previous circle. Some circles only have one colour, some have two, some four. Some circles fade between various colours. A simple but effective idea.

Colorsok

Move blocks of the same colour next to each other, anywhere on the board.

Comboling

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

Find a path which connects all the tiles. Each tile must be visited exactly one and all paths must be horizontal, vertical or 45 degree diagonals. A simple idea nicely executed. The alternative interface option displays a grid which is extremely useful when checking diagonals.

Complo, El (El Complo, El Compló)

This site is available in the Dutch, English and French languages. It offers a variety of different types of puzzles, including a number of Java applets which run on most computers. Being a Dutch web site, it inevitably has a version of Lingo :) . There is also a section of easier puzzles for children. Note that because it is spelt in Dutch, the URL includes the word "puzzels", not "puzzles".

Cube-It

http://www.onlineflashgames.org/10-puzzle-games/2901-flash-game-cubeit/play.html (external link verified Nov-07)

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-Star

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

http://www.ice13.com/dave (external link verified Oct-06)

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.

Day Of The Bobteds

Creator: Rob Allen.

Place one or more balls so that when they fall they will destroy all the Bodteds. This game has eighteen extremely varied levels. The number of balls you are given, the shape of the Bodteds and the curious devices all vary. By the way, while Google lists several hits for "bodted" I doubt if any of them are related to this game.

Digit Puzzle

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

http://www.doggnation.com (external link verified Mar-08)

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)

HIGHLY RECOMMENDED

Category: 2D turn based puzzle game. Download and install; various freeware and payware programs. The payware programs have free restricted demo versions.

Download file size: Architect's Edition/King Dugan's Dungeon 12,965KB; Journey To Rooted Hold demo 24,624KB; Journey To Rooted Hold full 54,371KB; The City Beneath demo 40.7MB.

Don't be put off by the name. DROD is a 100% puzzle game, and a first class one. It cannot be described as being a violent game, nor does it have any realtime element. Neither should you be put off by the complexity of the numerous different versions of DROD and the various DROD web sites.

DROD - The Game

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 (up, down, left, right or diagonally) or to turn so as to swing his sword (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). Most types of monsters move in a predictable way. 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.

DROD - The Web Sites And Program Versions

www.drod.net (external link verified Oct-06) offers the whole of the Architects Edition version of DROD, which can be downloaded free of charge. This 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 create your own challenges. Architect's Edition is the best version for beginners to DROD.

drod.caravelgames.com (external link verified Oct-06) has the same content as www.drod.net, except for a different home page.

www.caravelgames.com (external link verified Oct-06) offers the payware versions of DROD, namely Journey To Rooted Hold (JtRH) and King Dugan's Dungeon Version 2 (KDD2). JtRH features additional characters including Beethro's innocent and wayward nephew Halph and the formidable, invincible and incredibly arrogant 39th Slayer. JtRH has twenty-five main levels, plus a special bonus level. Both JtRH and KDD2 feature voice actors. JtRH and KDD2 can be downloaded (broadband is required due to large file sizes) or for a slightly higher charge they are available on mail order CD. Free demo versions of both JtRH and KDD2 can be downloaded, which only include the first few levels of each game. This web site also 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.

In addition, numerous additional dungeons (or "holds" to use the correct term) are available for both versions of the program. Most of these are free but some, called Smitemaster Selections (SS) are only available to the CaravelNet online gaming system's subscribers or on mail order CD's.

A new version of DROD, called The City Beneath (TCB) is now on sale. A trailer for it is available on YouTube (external link verified 17-May-08).

This is a variant of the D-Star concept originally devised by Joe Wingbermuehle. Collect all the red squares. Each time you select a direction you will keep moving until you hit a wall but you can swap places with a special grey square whenever you wish. The grey square makes the same moves but doesn't collect red squares. Except for the first few levels this swapping is the key to solving the puzzles.

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.

Category: Platform game. Download and install; freeware.

Download file size: 275MB.

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.

Fit Position

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

On each level, various shapes must be pushed into the required positions on a square board - but this is not Sokoban. 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.

Each of the one hundred levels of Hex-A-Hop has a pattern of hexagonal tiles of various types which your player character can walk round. On each level your obejctive is destroy all the green tiles. Each green tile is destroyed as you step off it. Cyan coloured tiles turn green on your first visit and are destroyed on your second visit. All green pillars drop down to become green tiles as soon as there are no green tiles left. Similarly, all cyan pillars drop to become cyan tiles as soon as there are no cyan tiles left. Cyan tiles and pillars need not be destroyed in order to complete a level. Various additional complications such as trampoline tiles, missile-shooting tiles and slippery ice tiles are gradually introduced as you work through the levels. You can consider each move for as long as you wish. The game's level has a hexagonal pattern which allows a choice if you are currently having problems completing some levels.

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.

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.

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.

Papalot is a new turn-based strategy and resource allocation game, currently in the early stages of development. At the moment the menu system and graphics are fairly rudimentary but gameplay seems to be fully operative. On each turn you have to decide whether to build a unit which will create money, or a unit which will attack the opposition. There are several possible units of each type. The game has ten levels with different starting conditions.

Category: 2D puzzle. Play online free of charge (the downloaded SWF file is quite large).

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

http://www.gamemakergames.com/?a=view&id=3095 (external link verified Jan-08)

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

Download file size: 1443KB.

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.

This is a pinball variant on the "Incredible Machine" concept. Design a pinball machine to make a ball reach its destination. After each attempt each of the pinball elements can be moved, rotated, etc as desired. A clever idea, well implemented, plus excellent sounds. However, the level design is poor with even the early levels requiring luck rather than skill to solve. Around level six everything became too vague and difficult for my liking.

The father cannot be left anywhere with any of the daughters unless the mother is present to keep the peace. The mother cannot be left anywhere with any of the sons unless the father is present to keep the peace. The criminal cannot be left anywhere with any of the family unless the policeman is present to keep the peace. Only the father, the mother and the policeman can operate the raft.

Rooms

Category: 2D sliding block/adventure game. Downloadable Shockwave animation file; freeware.

Download file size: full version 30MB; compact version 16MB.

To quote from the publisher's web site: "In Rooms, you're locked in this mysterious mansion with different rooms. Arrange rooms like a sliding puzzle, only using what's inside the room. Think about the location of rooms, using the right object at the right time."

To operate the game's main menu use the cursor left and right keys to move the man to a door, then the cursor up key to make him walk through the door.

The game consists of numerous levels. On each level a set of rooms are displayed in 2D, side on. Your objective is to reach the exit room and pass through its door.

Subject to walls, locked doors and the availability of ladders, it is possible to walk and climb between rooms by using the cursor keys.

A room can be slid into an empty space by holding down the left mouse key in a featureless area of the room, then moving the mouse pointer to one of the four direction arrows which appear, then releasing the mouse.

Clicking on a telephone will teleport the player to the other room which has a telephone. Clicking on a wardrobe will exchange the contents of the current room with that of the other room which has a wardrobe. The player does not move.

To pick up an object, stand near it and click it. To examine or use an object, left-click on the player, then click on one of the inventory objects displayed in the circles around the player.

It is possible to restart a level. This option is also offered should you die by walking outside any room, or into a room filled with water without wearing the fish bowl on your head.

A level password system allows progress to be saved.

http://www.letsmakeagame.com/index.php?option=com_content&task=view&id=27&Itemid=42 (external link verified Apr-08)

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

This is a turn-based puzzle game in which you play the role of a wild fire which has to burn as much land as possible. Unfortunately the program suffers from inadequate instructions and a first level which is far too difficult, but there seems to be an underlying good idea here. Users can submit additional levels.

The number alongside the "Burn!!!" button indicates your current burn points. This is not your score. Burn points can be thought of as analoguous to money in a tower defence game or mana in a spell-wielding game. The number of burn points is incremented at the end of each turn by the number of squares currently alight with your fire. Burn points can be spent on making a fire spread, making a fire jump, starting a new fire area by causing a meteor to fall, or putting out an enemy fire with rain. Each of these options takes a different number of burn points.

To make a fire spread, click on an existing square which is alight with your fire, then the "Spread" button, then a square horizontally or vertically adjacent to the first square. Other operations are performed in a similar manner. Provided sufficient burn points are available, one square can be made to spread to one, two, three or all four adjacent squares.

Fires burn for a different number of turns depending on the terrain. The number of turns that each square will remain burning is displayed after each turn.

Once you have performed all your desired spread, jump, meteor and rain operations for the current turn, click the "Burn!!!" button. You do not need to use all your burn points on each turn, and any unused points will be carried forward (without any interest payments) to the next turn.

Your score is displayed in a smaller font size above the four option buttons. This is separate to the burn points. Your score is incremented by one each time a square is completely burnt by your fire. On each level a specified score must be achieved.

Slide coloured circles along wires to destinations specified by colour shading. This is a very good puzzle idea but the implementation leaves a little to be desired.

This is a variant on the classic "make the ball travel to a target by changing direction after it stops on an obstacle" concept. This program features various coloured bars which act as barriers. One at a time, these barriers can be deactivated. As usual, you can change the ball's direction each time it stops on an obstacle, and you can do this as many times as you wish. However, the number of times you can activate and deactivate barriers is very strictly limited. The graphics of this program are not particularly attractive, and the creator's spelling/typing leaves something to be desired, but the puzzles are well done and fun.

Summer Bound

This is the simplest 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. Although this game only has thirty levels and none of them are extremely taxing, it is still a very worthwhile little program.

Subway Shuffle

Category: 2D network puzzle game. Apple Macintosh version: download and install (freeware). Java version: play online free of charge.

This is essentially a coin sliding puzzle, with the additional restriction that coins can only be slid along lines of the same colour and themselves. Despite the name, it cannot really be considered as being a railway puzzle, or a fast food sandwich restaurant chain puzzle! Regardless of categorisation, it is a clever idea and a good puzzle.

Tacoyaki

Category: Abstract puzzle. Play online for free.

The board consists of a square grid of counters which are white on one side and grey on the other. Your objective is to turn all the counters so that their white sides are showing. Clicking a counter turns it over - and also the other counters in the same diagonals.

(As far as I am aware, the name isn't a strange hybrid of Mexican and Japanese cuisine.)

The same concept as Tacoyaki, except that now clicking a counter to turn it over also turns over its immediate orthogonal neighbours (the counters above, below and to each side of it).

Tilez

Category: 2D abstract puzzle. Download and install; freeware beta test versions.

Download file size: 1384KB.

Tilez is a puzzle game currently (May-06) being beta tested. A ball has to be directed through a set of jewels by correctly positioning arrow tiles that alter its path. At this stage of development the idea and the level designs are good but the user interface still requires more work. There is no real-time element and you can consider each move for as long as you wish.

Rather than quoting a specific URL which may very quickly become out of date, for information about the program and a link to the distribution file (the file you download) search the DROD forum (external link verified May-06) for threads about the game.
