Champions League-Style Swiss Format with Pots
When UEFA overhauled the Champions League format in 2024, they replaced the traditional group stage with something more ambitious: a Swiss system with seeded pots. Thirty-six teams, eight rounds, no groups. Instead of playing the same three opponents twice, every team faces eight different opponents — all determined before a single match is played. The pot system ensures the draw is balanced by strength, and the full schedule is known from day one.
What changed and why
The old Champions League group stage had a problem. Four teams per group meant only six matches per team, and the outcomes were often predictable by matchday four. Groups with two dominant clubs produced dead-rubber matches. Groups of death punished unlucky draws.
The Swiss format with pots solves both issues. Every team plays more matches against a wider range of opponents, and the pot system ensures the initial draw is balanced rather than random. No more groups of death. No more groups where qualification is a formality.
How pots work
Before the tournament starts, all participants are divided into pots based on ranking, seeding, or any criteria the organizer chooses. In the Champions League, pots are based on UEFA club coefficients — the strongest clubs go into Pot 1, the next tier into Pot 2, and so on.
Once pots are assigned, the entire schedule is generated at draw time. The system creates matchups so that each participant plays a set number of matches against participants from other pots, and optionally within their own pot. The key difference from classic Swiss: all matchups are determined before the tournament begins. There is no round-by-round repairing based on standings.
In the Champions League, each team plays two opponents from every other pot (8 cross-pot matches total) — a configuration that produces exactly 8 rounds. But you can customize this: fewer cross-pot matches for a shorter tournament, or add within-pot matches for more variety.
The result is a schedule where every participant knows their full set of opponents from day one, but the draw is structured so that the strongest teams don't face each other in every round.
Swiss with Pots vs. Classic Swiss
The two formats solve the same problem — ranking a large field in fewer rounds than a round-robin — but they work differently.
Classic Swiss decides matchups round by round. After each round, participants with similar records face each other. You don't know who plays whom in Round 3 until Round 2 finishes. This creates a dynamic competition where pairings adapt to results in real time.
Swiss with Pots generates all matchups upfront. Participants are placed into skill tiers (pots), and a complete schedule is produced from the pot assignments. Every match is known before the tournament starts. This creates a structured competition where the draw itself is the main event — like the Champions League draw ceremony.
| Classic Swiss | Swiss with Pots | |
|---|---|---|
| Matchups | Decided round by round | All pre-generated at draw time |
| Schedule visibility | Next round only | Full schedule from day one |
| Adapts to results? | Yes — winners play winners | No — schedule is fixed |
| Best for | Dynamic competitions, chess-style events | Pre-planned events, clear seeding tiers |
If you are running a small event (8-12 participants) where seeding is less critical, Classic Swiss works perfectly. For larger events with clear skill tiers — 16, 24, or 36 participants — Swiss with Pots gives you a balanced, pre-determined schedule that everyone can plan around.

Setting it up in Score7
- Click Create Tournament, choose your sport and number of participants, and select Swiss as the format
- Go to Settings and open the tournament settings dialog
- Switch the Swiss Type toggle from "Classic" to "With Pots (Champions League style)"
- Configure pot settings:
- Number of Pots — how many seeded groups to divide participants into (2-8)
- Matches against each other pot — how many opponents each participant faces from each other pot
- Matches within own pot — optional same-pot matches (0 by default)
- The Number of Rounds updates automatically based on your configuration
- Save settings, then go to the Participants page
- Click Assign Pots to open the pot assignment dialog
- Each participant has a pot dropdown — they're initially distributed by list position (first group to Pot 1, next group to Pot 2, and so on). Pick a different pot from the dropdown to move a participant, or click Reassign by Position to reset to the default distribution
- Save — the full schedule is generated with all matches pre-populated
The number of participants must divide evenly into the number of pots — for example, 36 participants with 4 pots gives 9 per pot. If your participant count is prime (like 17, 19, 23, 29, 31), the With Pots toggle is disabled because there is no valid pot configuration. Add or drop a participant to land on a number that splits evenly.
All Swiss tiebreakers are available: Buchholz, Sonneborn-Berger, and ELO. You can reorder and toggle these to match your competition's ranking rules.

Best use cases
Large competitive events (16-36 participants). This is the sweet spot. Enough participants to fill multiple pots, enough rounds for the standings to produce meaningful rankings. Think regional championships, esports leagues, or pre-season club tournaments.
Events with clear seeding tiers. If your participants have obvious ranking differences — professional vs. semi-professional, division one vs. division two — pots let you structure the entire schedule around those tiers.
Pre-planned events where the schedule matters. When venues, broadcasters, or participants need to know the full schedule in advance, pre-generated fixtures are essential. Classic Swiss can't offer this because pairings depend on results.
Champions League watch parties and simulations. Running a prediction league or fantasy bracket for the actual Champions League? Use the same format your participants are already following on TV.
Any event where first-round blowouts would be a bad experience. If your top seed crushing your bottom seed in round one would sour the mood, pots prevent it by design.
The bottom line
The Swiss format with pots is what you get when you combine the efficiency of Swiss with the structure of seeded draws. All matchups are known before the first match, but the draw ensures balanced competition across skill tiers. UEFA chose it for the biggest club competition in the world. It works just as well for your 20-team weekend tournament. The top teams earn their matchups. The underdogs get a fair start. And by the final rounds, the standings reflect who actually performed — not who got lucky in the draw.
