Space shogi is a three-dimensional shogi variant invented by George R. Dekle Sr. in 1987. The gamespace comprises nine 9ÃÂ9 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.
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. Space shogi, however, gives the pieces freedom of three-dimensional movement.
Black starts the game occupying levels 1 through 3; White starts on levels 9 through 7.
