    Abstract: A method of playing a game where there is a first set of die, each of which has the numerical values of one through six thereon, and a second set of die each of which has plus, minus, division and multiplication signs thereon. The two sets of die are discharged onto a playing surface in a random pattern, and then the individual dice members of the first and second set are placed in an alternating pattern so that when the mathematical operations are performed as indicated in the alternating arrangement of the two sets of die, a desired maximum value is obtained.
