A dice game for 2 players. You have to transport your prisoners from one side to the other. The first one with all his prisoners at the other side is the winner. You have to throw with a black and a white dice. The numbers on the stones represent the escape gate. For instance when you throw 3 with the white stone you put one of your prisoners in the third white gate, with the black stone in the black gate. With six you may choose which gate. - BoardGameGeek
