A polo game is 6 chukkers (periods), 7 minutes and 30 seconds each. Most women’s tournaments are only 4 chukkers. The field is 300 yards long and 160 yards wide (about 9 american football fields). On the end line at each end are goal posts, 24 feet apart. Points are scored by hitting the ball between the posts. Each time a goal is scored the team changes direction of play. Like hockey on horseback!
It is legal to “hook” the hitter’s mallet. The game is very physical and can be dangerous. In between chukkers there is a 4 minute break for players to change ponies and get hydrated. After 3 chukkers there is a ten-minute “half time” where spectators come out and stomp divots. A typical match lasts 1 and 1/2 hours.
