English - A dexterity dice game consisting of four sets of colored dice one either slides, rolls, or flicks down a stepped surface. Usually one slides the die for better accuracy. After each person has slid their 4 dice, points are scored. You score the die roll times a multiplier of either 1×, 2×, 3×, or 4× depending on which area of the board the die is on.
