A Swiss tournament (from 1890s chess) sits between two extremes. A round robin makes everyone play everyone: accurate, but far too many games. A knockout sends you home after one loss: dramatic, but it throws away information. A Swiss keeps every team in and, each round, pairs teams on equal records.

1. Round 1 is seeded: the top half of the field plays the bottom half.
2. After that, teams are sorted by points and paired with the nearest team they haven’t met, so winners meet winners and stragglers drift down. Nobody is eliminated.
3. After a handful of rounds the standings are the ranking, with no bracket required.

Because opponents are always near-equals, almost every game is a coin-toss on paper, which is exactly what makes it informative: a 50/50 match tells you far more than a 5–0 mismatch. Over the same number of match-days as the World Cup you pack in many more useful comparisons, so the table tracks true ability much better than three group games and a knockout ladder. This tool adds a short knockout (semi-finals, then a final) onto a Swiss group phase, to keep a real final while keeping the accuracy.

What the dials mean

Competitive balance

How evenly matched the 48 teams are. Slide right and the ratings squeeze together, so weaker teams upset stronger ones more often.

Swiss rounds per group

How many games each team plays in its group. Rounds, plus a semi-final and a final, give the total match-days: the same calendar the real World Cup fills.

Send teams home when eliminated

Once a team can no longer reach the top 4 of its group it stops playing. It only drops teams that already cannot reach the semis, so it never changes who can win; it just thins the field for drama.

Record defends vs Penalties

Two ways to settle a drawn knockout game. “Record defends” sends through the team that finished higher in the group phase, rewarding a strong group run. “Penalties” decides a draw with a 50/50 shoot-out. You can set the semis and the final separately.

Seed

A team’s pre-tournament rank by rating, used to build balanced groups and to decide who defends a drawn game.

Record

The points a team has so far: 3 for a win, 1 for a draw.

Elo rating

A strength number for each team; a +100 gap is about a 63% chance of winning a single game.

The true best team

Whichever team actually has the highest ability once a tournament’s form is added: the team a flawless format would always crown. The bars show how often each format manages it.
