There are intervals of 3 mins between chukkas and 5 mins at half time. Ends are changed at every goal scored - this has been found fairest when there is a wind. In handicap tournaments the number of goals start is obtained by multiplying the difference between the two teams' handicaps by the number of chukkas and dividing by 6, any fraction counting a half a goal. There is no limit to the height of ponies. Any other player who crosses the player on the right of way close enough to be dangerous commits a foul.
Penalties vary according to the degree of danger and closeness of the cross.
No player may hook an opponent's stick unless he is on the same side of the opponent's pony as the ball. Dangerous play or rough handling is not allowed - a player may ride an opponent off, but must not charge in at an angle. The following penalties may be given. A goal is given if the cross is dangerous or deliberate in the vicinity of the goal. The ball is then thrown in 10 yds in front of the goal without ends being changed.
