The sides are made up of either one player per side (singles) or two players per side (doubles). The rules are the same for singles and doubles.
The players take turns and only one plays at a time. At the beginning of a turn the player (called the "striker") has one shot. After that shot
the turn ends, unless extra shots are earned. The turn ends when the striker has no more extra shots to play. Then it is the opponents turn to play.
Extra shots can be earned (1) By scoring the next hoop in order, earning one extra shot, or (2) By striking your ball so that it hits one of the other
three balls, earning two extra shots.
