Experience chess like never before. Chess: Fog of War adds a layer of imperfect information to traditional rules — you can only see the squares your pieces control. The rest stays hidden in the fog.

Can you predict enemy moves and plan your strategy without seeing their full board? Outsmart the Oracle AI or challenge a friend in local pass-and-play modes. This is tactical deduction, stealth, and chess strategy combined.

HOW FOG CHESS WORKS
Each piece reveals only the squares it can move to or attack. Pawns see their move and capture squares. Knights see their L-shaped destinations. Bishops, rooks, and queens see along their normal lines. The king sees one adjacent square in every direction. Everything else is fog.

Move through the fog and you may bump into a hidden enemy — capturing them or being blocked. There is no checkmate in fog mode. Capture the enemy king to win. Run out of legal moves and you lose.
