In Fog of War Chess, you can not see all the spaces on the board. You can only see a space on the board if it meets one of the following conditions:
- You have a piece on that square.
- You can move a piece to that square. This means you can see empty squares that you can move to, or an opponent's piece that you can capture.
- The square is directly in front of one of your Pawns, or it is an adjacent forward diagonal from one of your Pawns.
The object of the game is to capture your opponent's King. Since you and your opponent can not see the whole board, there are no check or checkmate conditions. A player can freely make a move that puts himself or herself in check.
Castling and en passant captures are allowed.
