For Singles:

1. Domino players of either sex and of legal age are allowed to participate. If an error is committed in the recording of data, the matches will be played exactly how they were indicated to the participants.
2. The tournament will be carried out according to the Swiss system (1 vs. 2 and 3 vs. 4).
3. The match is won with 100 points.  The director of the tournament, with no previous notice, can indicate the judges to collect the ballots of the participants that have not finished in 30 minutes and within the last two matches.  If time is up, the participants that accumulated the most points will win.
4. In order to begin the match, all dominoes are shuffled and each player picks one tile. Its value is determined by adding its two sides. The player whose tile has the highest value is the starting player. Turn taking will be counter-clockwise.  All dominoes are shuffled by any of the 4 players; the shuffling player will pick his/her tiles last.
5. If the match is initiated by a domino piece of two values, the side with the highest value will point towards his/her partner. Turn taking will rotate to the right, in other words each player gets one turn.
6. Hands should remain under the table until it is one’s turn.
7. All players must be facing toward the center of the table during each match.
8. One point will be disputed in each match.  In case of a tie, nobody will acquire points and the rotation continues.
9. Final scores will consist of the points accumulated during each match. If there were to be a tie of final scores, and a decision is needed in order to continue to further confrontations, the winner will be the participant with the best differential.  The second criteria for determining a decision to get rid of a tie, is the result amongst them.
10. If a participant does not have a tile that can be played, the participant should say, “pass”.  If a player passes his/her turn, having a tile which can be legally played, the participant will be penalized with a point from his/her personal score, in other words the participant forfeits the game.   If the tile is the player’s last one, the penalty will not be taken into effect.  If, by petition of the other participants, the match continues the sanction will not be carried out.  If the participant “passes” deliberately in order to prevent a lock, the whole match will be lost.

17. “False thinking” or “False passing” can be penalized at the moment they are committed or at the end of the match, depending on the moment the violation is detected.  If a player recognizes he/she is “false thinking” and apologizes at the moment or within 3 seconds he/she can avoid the infraction.  If that is not the case, the player will be not penalized with a point from his/her own personal score.  The penalty for “false thinking” will be applied if the other three players agree that a violation was committed. The partner of the player that committed the infraction will be penalized under any circumstance.  If the violation is not detected on time, if possible the match will restart.  When you place a tile that cant be legally played, penalty can only be applied if the tile was played; otherwise, the tile must be left facing up and the 13 point criterion will be applied.   If the tile was placed on the wrong side and the player or his/her partner recognize the mistake before the person who is next has played or passed, they will not be penalized and the other players will decide if the match continues or not, beginning with the player in turn.
18. Sanctions can only be applied the tournament judges.  If a player decides to protest any action, he/she should call upon the judge to decide whether an action should be penalized and do so accordingly.  The judge has the right to apply sanctions independently during the tournament when he/she believes there is a violation to any of the rules.
