To win
If the King reaches any board edge, the whites win.
If the King is captured, the blacks win.
To play
Move one piece in a horizontal or vertical direction to an available square.
If a piece is bracketed by 2 opponent's pieces (top+bottom or left+right), it is removed.
If the King is surrounded by 4 blacks, it is captured.
If you are surrounded or bracketed as a result of your move, you are not taken.
Exceptions
1- There is a "King's square" in the middle of the board. Only the king can land on it.
2- The "King's square" is considered as a surrounding piece by everyone.
3- A draw occurs if the same sequence is played three times.
