Play 21, an old schoolyard game where one player shoots foul shots. The player can make up to 3 in a row. If the foul shooter misses she and the other 2 players box out, rebound and try to score while defended. If the foul shooter makes 3 in a row she tries to score on the other two. Score two points for a field goal and one point for a free throw. Score exactly 21 to win. If you go over 21 points you go back to 13 points and play continues.
