A game of tactics. The 25 wooden playing pieces in 10 different colours are placed on the 25 squares on the board. Each player has a playing token and in turn places his/her token over one of the wooden playing pieces on the board, but the second player can't choose the same colour as the first. Following the rules of play tokens are moved until one player either:

• manages to move his token onto the piece occupied by his opponent and so takes him;
• moves his token onto a piece of the same colour as the piece on which his opponent's piece stands; or
• ensures that his opponent is unable to move, since all pieces in a vertical or horizontal line from his token have already been removed.

NB. This game appears to be very similar to the game Watch, also designed by Claude Soucie, but an online biography for Soucie indicates that Watch was published in 1979.
