摘要

The game requires a knowledge of numbers and the rules of arithmetic and uses a sloping playing surface, its top edge having a panel. This has three apertures, each of them having a wheel behind it. When these are rotated, a three figure number appears. The lower edge, opposite the panel, has several alcoves along it, these holding stacks of cards. These cards have numbers on them and the numbers are randomly distributed throughout the cards in the stacks. The player must select these cards as they appear face uppermost and by adding, subtracting etc. match the three figure number.
