Trishogi

Trishogi is a shogi variant for two players created by George R. Dekle Sr. in 1987.

The game is in all respects the same as shogi, except that piece moves have been transfigured for the triangular board-cell geometry.

Trishogi was included in World Game Review No.

[3] Trishogi has the same types and numbers of pieces as shogi, and all normal shogi rules apply, including initial setup (see diagram), drops, promotion, check, and checkmate.

But the triangular geometry creates special move patterns for the pieces.
