2.4 The referee will ensure that the rules of the game are observed in all cases. The referee has the option to call “let” and thereby designate a re-serve if he/she has not been able to properly assess a situation with certainty. The decision of the referee is final.

2.8 If the match is played with a time limit, the player who is ahead when time allotted for the set has expired will be declared the winner. If, when time has expired there is a draw, a coin will be tossed to determine which player will serve, and the next point wins.
2.9 The players will change sides after each set in match play. In the last set of the match the players will change sides after six (6) points are scored by one (1) player or after half of stop time has expired.
2.10 If only one (1) set is being played rule 2.9 applies.
2.11 The time limit for changing sides is one (1) minute (60 seconds). The referee gives an audible warning 15 seconds before the time-out or changing sides is finished. The referee calls out: 15 seconds.
2.12 When changing sides players will move to their right.
2.13 While changing sides time-out rules apply (see 3.1).
2.14 Before the match the player must announce the name of his/her coach to the referee. The player can announce his/her coach even if the coach is not present. The coach can enter/leave the room only when the set is over and the referee must open the door.

2.17 The coach must remain on the side of table of his player.
3. TIME OUTS |
3.1 Each player will be entitled to one (1) time-out of one (1) minute (60 seconds) during a set. Time-out requests must be made to the referee during a break in play. Time-out can be called either by the player or the coach. Only during a time-out and side changes any discussion can occur between the coach and the player (see also 2.12, 2.13).

4.1 Two (2) points are awarded for a goal. When a goal has been scored the referee gives a double-whistle signal.
4.2 Players may score points regardless of which player is serving.
4.3 One (1) point is awarded to the opponent of the player who hits the ball into the centreboard screen and stops its forward motion. The ball is considered in “forward motion” if the ball hits the bottom of the centreboard screen and directly passes onto the other side of the table.
4.4 One (1) point is awarded to the opponent of the player who hits the ball over the centreboard screen.
4.5. One (1) point is awarded to the opponent of the player who touches the ball with any part of his/her body, other than the bat or batting hand, within the playing area.
4.6 One (1) point is awarded to the opponent of the player whose bat or batting hand causes the ball to leave the playing area of the table.
4.7 One (1) point is awarded to the opponent of the player who traps or stops the ball for more than two (2) seconds, so that the ball is inaudible for the opponent. The measuring of the “two seconds” is not being done by stop watch, but is in the judgement of the referee.
4.8 One (1) point shall be awarded to the opponent of the player who hits the ball and it touches the top of the sidewall and/or top of the contact board and/or jumps back into the playing area.
4.9 No contact is allowed within the goal area with the ball. If that happens, one (1) point will be awarded to the opponent of that player. That means like this: If the ball touches the bat or batting-hand in the goal area and moves directly into the goal, there is a goal and two (2) points are awarded to the opponent. If the ball touches the bat or batting-hand, and after that touches any other part of the body, there is an illegal touch and one (1) point is awarded to the opponent. If the ball touches the bat or the batting-hand, and goes anywhere else, in or out of the table, there is an illegal defense and one (1) point is awarded to the opponent because of the first sentence in this rule: No contact is allowed within the goal area with the ball.
5. BEGINNING PLAY |
5.1 Before the match begins, the referee, time-and score-keeper, the players and the coaches will be introduced by the referee.
5.2 Before the match begins, the referee will inspect the opaque eye protection, the bats, any hand protection and the attire worn by the players.
5.3 Prior to the start of play, the referee will toss a coin. The player first on the list will be asked to choose head or tail. The player winning the coin toss will be given the choice of taking or giving away the first serve to his/her opponent.
5.4 The eye protection must be worn during the whole match. Warm-up, time-outs and side/ends changes are part of the match. The players are not allowed to touch his/her eye protection. He/she must ask the referee for permission to do so, even in breaks. If permission is given, he/she must turn away from the table. Before play resumes the referee checks the eye protection so it is correctly put on the face and properly darkened with no gaps to be seen through. If the player breaks this rule, one (1) point will be awarded to the opponent.
5.5 The referee will roll the ball to the player serving and ask both players, first the returner and then the server, if they are ready to play. When the referee receives positive acknowledgement from both players answering YES, the referee announces the score and then the number of the serve. Then the referee will signal the commencement of play by blowing the whistle once. This should be used by starting the match, set, after time-outs and unusually long breaks. (For example: A is the server. B is the opponent. “Is B ready? – Yes! – Is A ready? – Yes! – Let’s start, the score is zero zero. A’s first serve. – Whistle.”
6. SERVES |
6.1 After a whistle signal from the referee, the player serving the ball must do so within two (2) seconds. If he /she does not, one (1) point is awarded to the opponent. The same will happen if the player starts to serve before the referee has whistled.
6.2 The ball must be placed on the surface before serving. If this doesn’t occur the player loses one (1) point immediately.
6.3 When serving each swing at the ball will count as one (1) serve.
6.4 Each player will serve two (2) times consecutively.
6.5 A served ball must bounce off the sidewall exactly once prior to passing under the centreboard screen. If this does not occur, the referee must stop the play and one (1) point will be awarded to the opponent. If the served ball “slides” along one side of the table wall it is considered as multiple bounces and one (1) point is awarded to the opponent. When, during the serve, the ball hits the bottom of the centreboard screen and directly passes onto the other side of the table, no paying mistake will be called.
7. PLAY |
7.1 One (1) point shall be awarded to the opponent of a player who holds his/her non-batting hand within the playing area except when switching hands. Referee shall tolerate a non-playing hand over the playing area as long as it is part of a natural movement when swinging the bat for shooting the ball. The non-batting hand can overreach the contact board. The player is not allowed to put his/her fingers/hand down under the line of the contact board or grip the contact board with his/her fingers (rule 4.5 still applies). It is tolerated to lean the upper body into the playing area (rule 4.5 still applies).
7.2 The bat must be held in one hand at all times, except when switching hands. An infraction of this rule will result in the loss of one (1) point.
7.3 If the player drops the bat, he/she loses one (1) point immediately.
7.4 When a bat is broken and play cannot be continued the referee shall order a re-serve immediately. Any point(s) scored after a bat is broken are not counted even if the referee has not blown the whistle yet. The bat is considered broken when it is badly damaged or if one or more major parts of the bat broke off and are not attached to each other anymore.
8. DEAD BALL |
8.1. The referee will call a “dead ball” and a re-serve when, in his/her opinion, the ball is moving so slowly that it not will reach the point, where the opponent can take care of the ball and go on with the game, or a player has lost track of the ball.
8.2 If the ball is inaudible for more than two seconds the referee calls a dead ball.
9. PENALTIES |
9.1 Play must be from the end of the table. A player must not play from the side of the table. It’s not allowed to hold on to any part of the table with the non-playing hand, except at the end of the table. “The end” is defined by the curve of the table, including the whole curve. Holding outside of the this area will immediately cause a two (2) point penalty.
9.2 If, in the opinion of the referee, the player is hooking the ball with his/her fingers or thumb, the referee will issue a two (2) point penalty.
9.3 If, in the opinion of the referee, a player or coach is guilty of misconduct, such as:
a) Shoving, excessive or constant moving the table in a disturbing way,
b) Scraping the bat in a disturbing way,
c) Talking during play or break in play (except 2.12, 3.1),

9.4 In case of very serious misconduct (e.g. swearing at the referee, throwing the ball or the bat) the referee is entitled to immediately penalize the offending player (without having to warn him/her first). The offending player loses the match by default.
9.5 The player must be at the playing room at the specified time. If the referee waits for 5 minutes and the player does not appear, he/she loses the match by default. If a player repeatedly appears late he/she can be excluded from the tournament.
9.6 A two (2) point penalty is issued against the player who pushes any part of his/her body into the goal area from the outside.
9.7 If a mobile phone, watch or similar device of the player or of his/her coach rings, beeps etc. during the match, the referee issues a two (2) point penalty.
9.8 If the coach tries to give secret signs to his/her player between serves, it will at once be considered serious misconduct. The referee will directly send him/her out of the playing room. Additionally a two (2) point penalty will be issued against the player.
