1. The players stand outside the opposing squares and face each other.

2. The player with the ball starts by throwing the ball at the penny (no rolling or bouncing), trying to hit it and flip it over. The opposing player does the same. And they continue to take turns.

3. Scoring:
> 1 point is scored for every hit of the penny
> 2 points are scored if the penny flips over when hit
> Whoever reaches 11 (or 21) points first wins

You may also make up your own rules and way of scoring.
