General Rules

Each match will be led by a referee, except for the board games. Which team should deliver the referee is stated on the match schedule. The referee will always be delivered by a team that doesn’t have to play that round, so also make sure to look up when your team has to referee. In case of a no-show of the referee, this must be noted on the scoresheet. For each time this is the case, one point will be subtracted in the final results of the concerning study association. When the match has ended, the referee hands in the scoresheet to the field manager in the scoresheet box. In absence of a scoresheet, the final score will be noted as 0-0, and one point will be subtracted in the final results of the referee’s student association.

When a team is at least 5 minutes late, or doesn’t show up at all, the game is automatically won by the opponent, with a score equal to the largest difference within that poule on that day. Winning a match will get a team three points, a draw is worth one point and a lost game is worth none. For card games, a different system of scoring is applied.

The final ranking within a poule is determined by the amount of points earned. The highest scoring team of an association will count for the score of their association. If this appears to be the same, the special activity will count as a more important factor for the score and the association which did better at the special activity wins.

If problems occur regarding the score of a game, it is expected that the participants try to find a solution. Should this fail, the concerning field manager should be asked for help. In case help from the field manager still doesn’t lead to a solution, the organization should be asked for help.


Please note:

  • Kubb

    Own supplies to bring: Outdoor sport shoes
    A team consists of at least 3 and at most 6 players. Every round, they divide six throw-sticks among them.

    The field consists of two halfs. In the middle of the field, between the two halfs, stands the (wooden) king. On the baseline of both teams, five kubbs (wooden blocks) are placed.

    A stick is always thrown while standing behind the baseline. This baseline may, however, move during the game (see below)

    The team that is team 1 on the scoresheet starts throwing.

    Each round, a team throws its six sticks. The goal is to knock down the kubbs on the half of the other team. 

    A stick must always be thrown underhand (“onderhands¨) and with the tip towards the kubb. Throwing horizontally is not allowed.

    If one team knocks down one or more kubbs on the baseline, the other team starts its next round by throwing the knocked over kubbs to the opponent’s half. If a kubb is misthrown (on the own half or out of field), the team gets one retry. If a kubb is misthrown twice, the other team places the kubb wherever they like (but at least one stick away from the king)

    If a standing field kubb is knocked down, it is taken out of the game. It should not be thrown back to the opponent’s half again.

    A team may only knock down kubbs on the opponent’s baseline after all standing field kubbs are knocked down. 

    If at the end of a round one or more standing field kubbs remain on the half of the other team, the front kubb indicates the new baseline. In the next round, the other team may now throw their sticks while standing behind this new baseline. Any kubbs, however, must always be thrown while standing behind the original baseline.

    If no kubbs remain on the opponent’s half, a team may knock down the king. This must be done while standing behind the original baseline.

    The team that knocks down the king wins. If time runs out before that, the winning team is the team with the most kubbs (baseline kubbs + standing field kubbs) on its half. If at any point in the game a team knocks down the king invalidly, the other team wins.


    Petanque is played 3v3 on an official Petanque Court under the rules of the Dutch Jeu de Boules Association (NJBB).

    Before the game, a circle with a diameter of approximately 40 cm is drawn on the court. All players have to throw while standing in the circle.

    Each player throws two balls. This means that each team has 6 balls in total.

    The team that is team 1 on the scoresheet starts by throwing the but (small ball) approximately 6 to 10 meters away from the circle. 

    The team that throws the but also throws the first ball. The second ball is thrown by the other team.

    After the second ball, every next ball is thrown by the team that is the furthest away from the but. If a team has thrown all six balls, the other team throws all the balls it has left.

    At the end of each round, points are scored for each ball that is closer to the but than the opponent’s closest ball.

    The winning team draws a new circle around the but and throws the but to start the next round.

    When the time is up, the current round can be finished. The team that scored the most points wins.
