Rules

Each tournament is attended by 4 pairs consisting of two players.
Competing pairs play one meeting against each other in a round robin format on the principle of each against each other. Each of the pairs must play three meetings. The total number of all meetings in the tournament is 6 (six).

One meeting consists of one match. The match is played until one of the pairs wins in two sets. If each of the pairs wins one set, then an additional super tie-break is held to determine the winner of the meeting, which is played up to 10 points.

At the decision of the organizer(s), with a score of 9-9, the super tie-break can be held:
- up to a difference of two points
- up to a golden ball (i.e. the pair that wins the 19th point becomes the winner).

The set is played until a victory in 6 games with a difference of 2 games. Each game is played for from four minimum to seven maximum points (15-0, 15-15, 30-0, 30-15, 30-30, 40-0, 40-15, 40-30, 40-40, "Golden Point").
If the score is 6-6 in games in each of the two sets, a tie-break is called, which is played up to 7 points with a difference of two points (if the score is 6-6, they play up to a difference of two points).

The final places in the tournament are determined by counting the points awarded based on the results of the tournament in accordance with the following:
- for a win in two sets of the match, 3 points are awarded; 
- for a win in the super tie-break - 2 points; 
- for a loss in the super tie-break - 1 point;
- for a loss in a match in two sets – 0 points.

If two or more pairs of participants have equal points, the final places in the tournament are determined by the following indicators (in descending order of importance):
 

1. points scored in all matches played by the pair;
2. the difference between won and lost games in all matches. A super tie-break is worth two games (i.e. a minimum of 12 games and a maximum of 28 games can be played in a match);
3. the number of points scored in personal meetings between the compared pairs of participants;
4. the number of games won in matches between the compared pairs of participants;
5. the difference between won and lost balls in all tournament matches (a minimum of 48 balls can be played in a match);
6. according to the current rating of the pairs of participants, the one with the higher rating value is higher.
