Space shogi
9x9x9 variant of Japanese chess
Space shogi is a three-dimensional shogi variant invented by George R. Dekle Sr. in 1987.[1][2] 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.[3]
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.
Black's level 1 (and White's level 9, rank a) starting setup. Unlike standard shogi, the silver is placed between the lance and the knight (8i and 2i in the diagram).
Black's level 2 (and White's level 8, rank b) starting setup. The bishop and rook occupy the same positions as in standard shogi.
Black's level 3 (and White's level 7, rank c) starting setup. The pawns fill the same rank as in standard shogi.
