This is a dice game of math. The box contains 20 dice (half with numbers of varying distribution, half with arithmetic operations), note pad and rules. The rules specify four different games of varying complexity. In all games, the objective is to roll as high or low numbers as possible, but using different subsets of the dice. Since you also have operators at your disposal, sometimes it is also important in what order to use the numbers and operators.
