A little game teaching children basic math. Roll 3 dice and add any of the dice to reach the next number on a track going from 1 to 12 and down to 1 again. Dice can be used more than once, but only once in each combination. So for example rolling a 1, 2 and 4, you could jump to 1, then 2, 3 (2+1), 4, 5 (4+1), 6 (4+2), and finally to 7 (1+2+4) all in one go. The advanced game lets you subtract numbers as well as add them, but in fact this makes the game easier and quicker. With even more advanced rules you add multiplication and division.
