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 2×2 square, have four more plots than his opponent, or to have claimed seven plots anywhere wins the game.

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).

(ID: caravan)
(ID: cascades)
27724 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 8×8 (really 8×15 if you measured it at the bottom) is already nontrivial and 10×10 might be “tournament”.

30994 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.

The unusual theme of the game keeps it fun whilst also enabling considerable strategic variety and depth.

(ID: magneton)
16778 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.

Mak-yek is a board game played in Siam and Malaysia (under the name Apit-sodok). It is a game of custodial capture. An ‘Edges’ variant is available that uses the edges of the board in captures.
Martian Chess
(ID: martianchess)
19803 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.
