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?

Chess, but you build your own army. Start with normal pieces. Lose. Earn coins. Buy modifier cards that give your pieces new movement abilities - a Rook that leaps like a Knight becomes a Chancellor. A Bishop that slides like a Rook becomes a Queen. Stack enough upgrades and your pieces become monsters the AI never saw coming. PLAY → EARN → UPGRADE → RETRY Every game earns currency, win or lose. Losing is part of the plan. Spend coins on modifier cards between games, equip them on up to 5 pieces, and go again with a stronger army. The loop is addictive. The power fantasy is real. 10 MODIFIER CARDS • +Knight - give any piece the Knight's L-shaped leap • +Bishop - add diagonal sliding to a Rook or Knight • +Rook - add straight-line power to a Bishop or Knight • +Camel - the Knight's weird cousin: a (3,1) leap • +Knight & Bishop - create an Archbishop • +Knight & Rook - create a Chancellor • +Rook & Bishop - create a Queen from scratch • And more. Stack them. Break things. FAIRY CHESS PIECES Chancellor. Archbishop. Amazon. Centaur. Names you've seen on Wikipedia at 2am. Now they're in your army, doing absurd things on an 8×8 board. Every upgrade is a real fairy chess piece with movement rules that have existed for centuries, we just put them in your hands. NO ADS. NO WAIT TIMERS. NO ENERGY SYSTEM. Play as much as you want.
