Definition:Matching Pennies

Definition
Matching pennies is a two-person game whose mechanics are as follows. There are two players: $A$ and $B$.

Each player puts down a coin, traditionally a penny, either head or tail up, without showing it to the other player.

The coins are then uncovered.

If they both show the same side, $A$ is deemed to have won, and he takes both coins.

If they show different sides, $B$ is deemed to have won, and he takes both coins.
