Everyone knows that math, in the form of probability, lurks behind everycard game. But two new games make math their explicit focus, and in themore recognizable form of arithmetic. The first, called 1-2-3 OY!, uses adeck of cards numbered 1 through 16 with wild OY! cards interspersed. Itcan be used to play many games, all of which involve lickety-splitarithmetic and periodic yells of "OY!" The second game goes by the nameof Zetre, and features three dice as well as its own deck. It too willkeep your reflexes sharp and have your brain dancing with numbers.
