How to Play
Prism Chess is played on a standard 8×8 chess board with one addition: the middle four rows are divided into eight 2×2 grids that you can rotate 180° on your turn.
On each turn, you make one piece move (mandatory) and optionally rotate one grid (before or after your move). Use rotations to reposition pieces, clear paths, and create new tactical opportunities.
The game can be won by traditional checkmate or by using a rotation to expose the opponent's king and capturing it in the same turn.
