Hand Cricket

both hands open at once.

the playground game: same number and you are out, one over each

Two hands open at the same instant. If the numbers match the batter is out; if they differ the batter keeps whatever they threw. One over each way, six balls, and the second innings is a chase. Both numbers are committed before either is shown -- the opponent draws its number the moment the previous ball resolves, so it can never be a reply to yours. It throws uniformly at random, which means every ball is one in six however you play it.

Concepts: chance, randomness.
