4. "Stick checks" are allowed only between racquets. A player who strikes another player's body with his or her racquet will be carded and the opposing team will receive a penalty shot. This includes using one's racquet to trip another player. A stick check against another player's helmet is an immediate red card and earns the wounded team a penalty shot on goal.

5. Balls may only be carried for 10 steps, at which point they must be passed. Acceptable passes are to a teammate, to oneself via a rebound, or a shot on goal.

6. One yellow card is a warning. Two result in the player sitting out the remainder of the game. A player who is red-carded is immediately expelled from the ongoing game and must sit out of the next one as well.

7. Exy games for youths and high schoolers require four referees at minimum. From the NCAA level upward six are required, three to either side of the court.

8. Goalkeepers are the only players allowed to touch the ball with their hands. Players cannot catch, kick, or otherwise interfere with the ball unless using their racquets. Violation of this is a stop-play and switch of possession.
