Choose your tournament format

Start with how participants should advance or be ranked. Each option opens a dedicated generator with its own rules and tools.

3–64 participants

Single Elimination

One loss eliminates a participant. It is the fastest, simplest format and uses the fewest games.

Best for: Fast knockouts and events with limited time.

Create a Single Elimination bracket

4–64 participants

Double Elimination

A second competitive loss eliminates a participant, using connected Winners and Losers brackets.

Best for: Events that want a second chance after one loss.

Create a Double Elimination bracket

2–32 participants

Round Robin

Every participant plays every other participant, and results produce transparent standings and leaders.

Best for: Leagues and complete head-to-head schedules.

Create a Round Robin schedule

4–64 participants

Swiss System

Participants play a limited number of rounds against similarly ranked opponents without rematches.

Best for: Larger events that need meaningful standings with fewer games than Round Robin.

Create a Swiss tournament

4–32 participants

3 Game Guarantee

A Double Elimination championship plus terminal guarantee games ensures every participant completes at least three real games.

Best for: Events that promise a third real game without creating a third championship path.

The right format depends on available time, how many games each participant should receive, and how the event should choose its winner or leaders.

Which tournament format should I use?

Use the event constraint that matters most as the deciding rule.

  • Fastest and simplest: Single Elimination uses the fewest games and removes a participant after one loss.
  • A second chance after one loss: Double Elimination moves the first-loss participant into a Losers Bracket.
  • Everyone should play everyone: Round Robin creates a complete schedule and derives standings from recorded results.
  • Fewer rounds for a larger field: Swiss System pairs participants near their current score while avoiding rematches.
  • At least three real games for everyone: 3 Game Guarantee adds a terminal third game for early two-loss participants without creating a third championship path.
