Competition Format

In Hungary, 12 men's teams are divided in 3 pools of 4 and 13 women's are divided in 3 pools of 3 and 1 pool of 4 teams and seeded automatically based on the 3x3 Federation Ranking at the cut-off date of 5 July.

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 and the knock-out games on Day 2.

11 teams qualify for the FIBA 3x3 U18 Europe Cup:

. 5 mens' teams (4 QF winners + 1 winners of loser's bracket)
. 6 women's teams (4 QF winners + 2 winners of loser's bracket)

Hungary's men and women are automatically qualified as hosts. If they are one of the best 5 teams (in men) or 6 teams (in women), then the next team ranked in the final standings qualify.
