The colorful board is divided into 64 (8x8) squares in 16 different colors, 4 squares of each color. The players take turns placing one of their four pawns on any unoccupied square of any color. After the set-up phase the pawns move like chess rooks, i. e. any number of squares in a straight line onto an empty square, without capturing or jumping over another pawn. Whoever places his four pawns on the four squares of a single color wins the game. The title, a variant German spelling of 'Bluff', refers to the distracting nature of the board - the rules advise keeping your opponent in the dark about your desired winning combination. - BoardGameGeek
