Space shogi



Space shogi is a three-dimensional shogi variant invented by George R. Dekle Sr. in 1987. The gamespace comprises nine 9×9 shogi boards stacked vertically. Each player controls a standard set of shogi pieces.

Space shogi was included in World Game Review No. 10 edited by Michael Keller.

Game rules
Space shogi follows standard shogi conventions, including the same types and numbers of pieces, and a similar initial setup. All the normal shogi rules apply, including drops, promotion, check, checkmate, and impasse. But pieces have the freedom of three-dimensional movement.

Starting setup
Black starts the game occupying levels 1 through 3; White starts on levels 9 through 7.
