Prism Chess is chess — with a twist. Literally. Play on a standard 8×8 board with all the classic rules you know, plus one game-changing addition: the middle of the board is divided into eight 2×2 grids that you can rotate 180° on your turn. Every turn, you make a move — and optionally spin one of the grids before or after. Rotate to reposition your pieces, disrupt your opponent’s formation, clear a path to their king, or set up a devastating capture. The rotation zone spans the four middle rows of the board, turning familiar chess positions into entirely new tactical puzzles. Prism Chess introduces a win condition unique to the game: rotate a grid to expose the opponent’s king, then capture it in the same turn. No check announcement, no chance to respond — the king is simply taken. Players must think defensively about rotation threats at all times, even when the king is safely on the back rank. FEATURES: • Two Players — Play locally on a single device with a friend • vs Computer — Challenge the AI at Easy, Medium, or Hard difficulty • Full Chess Engine — All standard chess rules including castling, en passant, promotion, and checkmate • Rotation Mechanics — Spin any of 8 grids in the middle of the board 180° as part of your turn • Grid Guides — Visual indicators show the rotation zones on the board • Move Log — Track every move and rotation throughout the game • Undo — Take back your last move All the depth of chess with an entirely new strategic dimension. Can you think one spin ahead?
