Golf Croquet is also played at International level and is increasing in popularity. The rules are simpler (than Association) and, although a game can be highly competitive, it is quite sociable by virtue of the fact that all players are on the court for the whole game.
The game is played as singles or doubles and the 4 coloured balls (blue, red, black, yellow) must be played in the correct sequence with each player striking his/her own ball once in a turn. The game commences with each player hitting his/her ball from corner 4. The first team to 'run' a hoop (ie put one of their balls through a hoop) in the right direction scores the hoop. Play then moves to the next hoop in sequence. The two teams battle for each hoop and this may involve a team using one of their balls to knock an opponent's ball away from a hoop running position. The game requires both skill and tactics with the possible options changing after every turn. In a 13 point game the first team to score 7 hoops is the winner with a typical game being played in about 45 minutes.
