Super Duper Games (2005–2023)

Super Duper Games has finally been decommissioned. It has been on life support for many years, kept alive by the generosity of donors, but now that its successor is live and stable, it was time. If you love abstract strategy games, please come join us on Abstract Play.

Below is the list of the 117 games available here as of its demise. Links to external sites and archived files are still active. A complete archive of the wiki, forums, completed games, and even POVRAY koans are available from my SDG archive folder on Google drive.

I want to thank all the players who supported and encouraged me over the years. I am proud of the community we built here, and I hope to rebuild some of that at Abstract Play. From the bottom of my heart, thank you.

Two player game where one plays the Builder, the other the Destroyer. Square tiles are place in 2x2 plots on a 4x4 grid. The object of the builder is to build up a set of two-story 2x2x2 "houses" (four in a row, four square or a majority) while the destroyer is trying to create the same array of empty plots. On each turn, the players select from a one-out-of-five tile placement or removal set (one on each of five different plots, one on each of one and two on one; two on two, three on one and one on one; four on one). Only three are available on any turn, as a player cannot pick one set that has been placed in the previous two turns. Once a plot is completely built or torn down, it is claimed by a player. The first player to claim four plots in a row (horizontally, vertically, or diagonally), four plots in a 2x2 square, have four more plots than his opponent, or to have claimed seven plots anywhere wins the game.

(edit)

Alien City is a fascinating Piecepack/Icehouse game that is set in the far future and concerns the building of a city on a newly colonized world. Cities in this future contain two types of structures, towers and domes. Towers are owned by the various guilds. Domes are smaller structures used to house the citizens. As with the towers, domes are always associated with a particular guild.

The game-play consists of the players alternating turns, placing a tower or dome each turn until either all available towers and domes have been placed or until there are no legal construction sites remaining within the city. Then scores are determined based upon the relative positions of the towers and domes.

The game is played on a square grid. Each player starts with four queens (as in chess queens) placed in predetermined locations on their side of the board. On a players turn, they move a queen and then fire an arrow from that queen (the arrow piece moves like a queen also). The space that the arrow lands on creates a permanent block on the board. Arrows can not be shot through queens or arrows. The first player who can not make a legal move (move a queen and then shoot) loses the game.

Icehouse
(edit)

Branches and Twigs and Thorns (or "Barsoomite Go") is an elegant little strategy game for two or four players that uses Icehouse pieces. It is a turn-based game, unlike Icehouse or IceTowers; and there is no luck involved. Like Martain Go, it uses a chessboard, a set of Icehouse pieces for each player, and a collection of tokens (at least ten per player). Players seek to build chains of pieces of their own color and to force their opponents to branch off from opposing pieces of their opponent's colors, which results in a penalty determined by the sizes of the pieces involved.

Hexagonal Board
(edit)

Some words from the author: For some time now [Apr 16, 2001] I have been toying with the idea of trying to model/abstract the flow of water carving out a mountainside. A related geometric pattern is the fractal on certain seashells. [...] The image in my mind is a root-pattern forming or tributaries of a river. [...] The game generalizes to any MxN board. Without more experience playing and "figuring it out" I don't know how M and N affect playability. My intuition suggests 8x8 (really 8x15 if you measured it at the bottom) is already nontrivial and 10x10 might be "tournament".

Fanorona is the national game of Madagascar, and it is believed to have been derived from the game of Alquerque. Alquerque is a game played in Arab countries, and archeological finds in Egypt suggest that it may date back more than 3,000 years. Alquerque could have been brought to Madagascar by traders and developed into Fanorona in the 17th century or even earlier.

Fanorona is a really intriguing board game. It has a long history, but it doesn't belong to a family of similar games like chess, draughts or mancala. Like Go it is a real one-off, with a unique method of capturing.

This is a game where two populations compete for survival. Pieces have gender, can �mate�, give birth, age and die. The game is won by the player whose population lives longest or who connects two sides of the board. The longevity of pieces gets around the diagonal cut problem of playing a connection game using a board with squares. This has been solved elsewhere by going into three (physical)- dimensions, - here the extra dimension is time. The unusual theme of the game keeps it fun whilst also enabling considerable strategic variety and depth.

This is another game for 2 players. Players place their pieces in an attempt to connect four in a row. The problem is, as pieces are placed or moved, they exert magnetic forces on surrounding pieces (likes repel, opposites attract) thus the lay of the land is in constant flux. It will take planning and foresight to succeed.

I have implemented a "Weak Force" variation which will only attract/repel other pieces one space at a time, instead of as far as possible.

(edit)

Martian Chess is another Icehouse game created by Andy Looney. It is a chess-like strategy game in which location, rather than piece color, determines which pieces you may move. Like Chess, each type of piece has its own way of moving, and you capture by moving onto an opponent's square; but unlike Chess, you can only move pieces sitting in your own quadrant, and only attack those in other quadrants which may include your own former pieces. The game ends when someone runs out of pieces, and the winner is the player who captured the most points. A variant called 'Of Knights and Kings' changes the way Pawns and Drones move to create a very different strategic game.

Several factors combine to make this a very fast and exhilerating game. These factors are line-of-sight connection (which is a feature in Sid Sackson's unusual game, Network); graded placement; and, finally, equivalent goals---either player can win by connecting North to South *or* West to East.

Tanbo is a game of roots. Played on a standard Go board, players attempt to constrict and kill opposing roots by expanding their own. Only one player's roots will survive. It should be noted that like BTT and Sprawl, an early resignation in the 4-player game will cause the game to be abandoned and left unrated. Please be courteous when joining such games, especially since Tanbo is a relatively lengthy game.

Terratain is another Warpspawn Game. Players lay tiles of various types on the board according to a very small set of rules. Once the board is full, scores are assigned based on things like: lines of similar colour, most pieces of a certain type, or patterns of controlled territories. You can play the game blind where scores are not displayed until the end, or you can choose one of the variants to get an idea of how people are doing throughout the game. Some minor modifications were made to the scoring rules and are described in the wiki.

Thank you, Lexicon for coding this game for us!

Volcano is a clever, puzzle-style game in which players move "caps" around on top of a group of volcanoes, triggering eruptions which cause colored streams of lava to flow out across the playing field. The object of the game is to capture as many pieces as possible, with bonus points awarded for special combinations. Each player attempts to accumulate the highest score and then bring the game to a close before another player has a chance to steal the lead away. This implementation supports 2-10 players.

A 2-player abstract strategy game in the vein of Pente or Othello. Four types of stones are arrayed on a 9x9 board: earthstones, suns, moons, and crowns. One player plays the suns, and the other player plays the moons. Players take turns removing stones or groups of stones from the board. A player may make one of three moves: (a) removing one earthstone, (b) removing one of their own stones, or (c) removing all of the stones in an unbroken line between two empty board spaces. Players score based on the type of stone removed: 1 point for an earthstone, 2 points for an opposing player's stone, and 5 points for a crown. The first player to reach 50 points wins.
