Martian chess

Martian Chess is an abstract strategy game for two or four players invented by Andrew Looney in 1999. It is played with Icehouse pyramids on a chessboard. To play with a number of players other than two or four, a non-Euclidean surface can be tiled to produce a board of the required size, allowing up to six players. In his review in Abstract Games Magazine, Kerry Handscomb stated: The first thing to note about Martian Chess is that it is not a chess-type game at all. Instead, the objective is to accumulate points by capturing pieces. Martian Chess is [...] an original game with novel tactics and strategy. In 1996, Looney had invented Monochrome Chess, a similar two-player game that uses regular chess pieces where the half of the board determined who controlled a piece. While the king is not royal, the king and rook can castle.
