Physical Contact
A player may use their body (but not their elbows) and pony to push his opponent off the ball providing their pony's shoulders are not ahead of the others. They may use their stick to hook an opponent's stick to spoil their shot, but not above shoulder height or between the ponies legs.

Right-of-Way
During play there is an imaginary "line of ball", which is generally the direction in which the ball is travelling at any one moment. When a player has established right-of-way along that line, it may not be crossed by opposing player if there is the slightest risk of collision.

Time Out
Play and the clock stop if an umpire blows his whistle, which they do if a foul is committed, a pony falls or has dangerous tack, or a player is injured.

Level of Play
High-goal tournaments and matches are between teams with handicaps of 17-22 goals; medium-goal upper limit of 15; intermediate upper limit of 12; and low goal limits of 0-4, 0-6 or 4-8. Open tournaments are played with no handicap limits.
