Croquet is played at all levels up to international level. It involves four balls teamed in pairs, with both balls going through every hoop for one pair to win. The game's distinguishing feature is the "croquet" shot: when certain balls hit other balls, extra shots are allowed. The six hoops are arranged three at each end of the court, with a centre peg. One side takes the black and blue balls, the other takes red and yellow. At each turn, players can choose to play with either of their balls for that turn. At the start of a turn, the player plays a stroke. If the player either hits the ball through the correct hoop ("runs" the hoop), or hits another ball (a "roquet"), the turn continues.
