Swiss Tournament Bracket Maker - Pair by Record
Run a Swiss tournament: fixed number of rounds, pair players with similar records each round, no eliminations. Used in chess, card games, and large fields where round robin would take too long.

Best Use Cases for Swiss
Chess Tournaments
The original Swiss system format. Balances competitive play without requiring every player to face every other player. Standard for club and regional chess events.
Card Games
Magic: The Gathering, Pokemon TCG, Yu-Gi-Oh, and most collectible card games use Swiss. Large field (64-256 players) but manageable number of rounds.
Large Casual Fields
Any event with 16+ participants where round robin would take too long. Swiss delivers clear rankings after 4-6 rounds without eliminating anyone early.

About This Swiss Implementation
This generator uses a simplified Swiss pairing algorithm: it pairs players by win record, avoids rematches, and handles odd team counts with byes. It does not implement full FIDE Swiss rules (colour balance for chess, accelerated pairings, Buchholz tiebreaks, float rules). For serious rated chess tournaments, use a FIDE-compliant pairing program. For everything else - card games, office tournaments, casual play - this simplified version works well.
