About this game

Chess: Fog of War adds a strategic fog-of-war layer to the classic game of chess. You can only see squares your pieces control — everything else is hidden. Outthink and outmaneuver your opponent in the darkness.

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 of movement. The king sees one square in every direction. All other squares are covered by fog.

If you move a piece through the fog and an enemy is hidden in the way, you bump into them — capturing them or being blocked. There is no checkmate in fog mode. You win by capturing the enemy king. If you run out of legal moves, you lose.
