Single Elimination Tournament

Learn about single elimination tournaments - the most popular tournament format used in March Madness, World Cup, and countless competitions worldwide.

What is Single Elimination?

Basic Concept

In a single elimination tournament, competitors are eliminated from the competition after losing just one match or game. This creates a bracket structure where winners advance and losers are immediately eliminated.

Win = Advance to next round
Lose = Eliminated from tournament
Tournament Structure

Single elimination brackets are organized in a tree structure, with participants paired in matches. Winners advance to fill spots in the next round until only one competitor remains.

Round 1: All participants compete
Round 2: Half remaining compete
Continue until one winner remains

  • Simplicity: Easy to understand and follow bracket progression
  • Fairness: Every participant has an equal chance to advance
