The game is played with 20 pieces each on a 10x10 square board. Each piece has a numeric value, based on a military rank, which is hidden from the opponent and only revealed when an attacking piece moves in front of a square occupied by an opponent's piece. In most cases, the piece with the highest value wins and the losing piece is removed from the board. Exceptions are the spy, who only takes the general and the mineur, who only defuses mines. The game continues until one player finds the opponent's quille and takes it. —user summary
