Hexshogi has the same types and numbers of pieces as shogi, and all normal shogi rules apply, including a similar initial setup (see diagram), drops, promotion, check, checkmate, and impasse. As in shogi, pieces capture the same as they move. But the hexagonal geometry implies special move patterns for the pieces.
The diagrams show how the unpromoted pieces move. As in shogi, a dragon king (promoted rook) moves as a rook, or as a king. A dragon horse (promoted bishop) moves as a bishop or a king.
The rook (4d) moves in six directions along vertical or oblique files (in the diagram, to any green-colored cell).[a] The king (7h) moves one step in any direction (red dots).[a] The gold general (7c, blue dots) moves one step like a rook, or one step diagonally forward. The silver general (3f, blue dots) moves one step in any direction diagonally, or one step straight forward.
The bishop (4d) moves in six directions along board diagonals (green-colored cells).[a] The lance (9i) moves straight forward only (blue-colored cells). As in shogi, knights leap any intervening men and have two possible forward moves (7e, blue dots).[a] A pawn (4h) always moves one cell straight forward (blue dot).
^ abcdThe Hexshogi rook, bishop, and king have the same moves as their counterpart pieces in Gliński's hexagonal chess. (Also the Hexshogi knight, except that the knight is restricted, as in shogi, to the two most straight-forward moves.) (Pritchard 2007:260)
