Pool play is a two-stage tournament format. First, teams are split into small groups called pools, and each team plays every other team in its pool. Then the top finishers from each pool advance to a single-elimination playoff bracket that decides the champion.
It's the most common format for weekend basketball tournaments, because every team is guaranteed several games, but the event still ends with a win-or-go-home championship.
How pool play works, step by step
- Seed the teams.Rank the field from strongest (1) to weakest, or use registration order if you don't know the teams.
- Split them into pools.Pools are usually 3–4 teams, labeled A, B, C… Seeds are spread out in a “snake” (1 and 2 land in different pools) so no pool is stacked.
- Play a round robin in each pool. Every team plays every other team in its pool once.
- Rank each pool. Standings are set by record, then tiebreakers.
- Advance to the playoff. The top one or two teams from each pool move into a single-elimination bracket.
An example: 8 teams, 2 pools
| Pool A | Pool B |
|---|---|
| Seed 1 | Seed 2 |
| Seed 4 | Seed 3 |
| Seed 5 | Seed 6 |
| Seed 8 | Seed 7 |
Each pool of four plays 6 games (every pairing once), so every team plays 3 pool games, for 12 pool games in total. If the top two in each pool advance, the playoff is a 4-team bracket:
- Semifinal 1: Pool A winner vs. Pool B runner-up
- Semifinal 2: Pool B winner vs. Pool A runner-up
- Final: the two semifinal winners
That's 15 games total, and every team plays at least three. Compare that to a straight 8-team single-elimination bracket: 7 games, and half the field plays only once.
Pool play tiebreakers
With only three or four games, ties in the standings are common. The usual order is:
- Wins (overall pool record)
- Point differential — points scored minus points allowed. Many events cap it (for example, ±15 per game) to discourage running up the score.
- Points scored
- Head-to-head or a coin flip as the last resort. Some organizers move head-to-head first when exactly two teams are tied.
Whatever order you use, publish it before the event. Tiebreaker arguments are much easier to settle when everyone saw the rules in advance.
How many teams should advance?
- 2 pools: top 2 from each, for a 4-team playoff (semis + final).
- 4 pools: top 2 from each, for an 8-team playoff (quarters, semis, final).
- 3 pools: top 2 from each makes 6 teams. The two best pool winners get a bye, or you can advance only pool winners plus the best runner-up.
Advancing more teams means more playoff games and more court time, so check the math against your gym hours. Our formats guide has the formula.
Pros and cons of pool play
Pros
