Competition Format

In Latvia, 15 men's teams are divided in 3 pools of 4 and 1 pool of 3, and 12 women's teams in 4 pools of 3 and seeded automatically based on the 3x3 Federation Ranking.

All teams play every other in their respective pools. The best 2 in each group qualify for the quarter-finals.

In case teams are tied in the pools, the tie-breakers are as follows:

1. Most wins (or win ratio in case of unequal number of games in inter-pool comparison);
2. Head-to-head confrontation (only taking win/loss into account);
3. Most points scored in average (without considering winning scores of forfeits)

If teams are still tied after those three steps, the one(s) with the highest seeding win(s) the tie-breaker.

After the pools, the teams play knock-out games all the way to the final.

All pool games are played on Day 1 (on 2 courts) and the knock-out games on Day 2.
