Your 43 Team Round Robin Tournament
How does a 43 Team Round Robin Tournament work?
In a 43 team round robin tournament, each team plays against every other team exactly once. The format ensures that each team has a fair opportunity to compete against all other teams.
Number of Matches:
The 43 team round robin schedule is made up of 42 rounds. Each team will play a total of 42 games and there will be a total of 903 games played in the entire tournament.
Byes:
Since there is an odd number of teams, one team will have a bye each round in a 43 team round robin tournament.
Tiebreakers (if necessary):
When playing a bracket style tournament, there must always be a winner declared so they can move forward in the bracket. This is not the case with round robin tournaments. It is not uncommon for a round robin match to be allowed to end in a tie. This is completely up to the tournament director, but all tie-breaker rules should be made known before the tournament begins.
Tournament Planning Guide
Time Requirements:
Round robin tournaments take longer than elimination formats but provide more games. Plan for 226-301 hours depending on team count and available fields.
Field Requirements:
Minimum 151 fields recommended for smooth operation. More fields reduce waiting time and tournament duration.
Scoring Systems:
Use wins/losses, points (3 for win, 1 for tie), or run differential. Establish tiebreaker rules before the tournament starts.

How to Calculate Round Robin Tournaments
Round Robin Tournament Formula
Total Games Formula:
Formula: n × (n-1) ÷ 2
Where 'n' is the number of teams. This calculates how many unique matchups exist when every team plays every other team exactly once.
Games Per Team:
Formula: n - 1
Each team plays against every other team exactly once, so they play one less game than the total number of teams.
Number of Rounds:
Formula: n - 1 (even teams) or n (odd teams)
With even teams, games can be scheduled perfectly. With odd teams, one team has a bye each round.
Step-by-Step Calculation Examples
6 Team Round Robin:
• Total games: 6 × (6-1) ÷ 2 = 15 games
• Games per team: 6 - 1 = 5 games each
• Rounds needed: 5 rounds (even teams)
• Tournament time: 3-4 hours
8 Team Round Robin:
• Total games: 8 × (8-1) ÷ 2 = 28 games
• Games per team: 8 - 1 = 7 games each
• Rounds needed: 7 rounds (even teams)
• Tournament time: 5-7 hours
7 Team Round Robin:
• Total games: 7 × (7-1) ÷ 2 = 21 games
• Games per team: 7 - 1 = 6 games each
• Rounds needed: 7 rounds (one bye per round)
• Tournament time: 4-6 hours

Quick Reference: How Many Games is a X Team Round-Robin?
Manual Calculation Steps
Step 1: Count Your Teams
Determine the exact number of teams participating in your tournament. This is your 'n' value.
Step 2: Apply the Formula
Total games = n × (n-1) ÷ 2. For example, with 10 teams: 10 × 9 ÷ 2 = 45 games.
Step 3: Calculate Games Per Team
Each team plays (n-1) games. With 10 teams, each team plays 9 games.
Step 4: Plan Tournament Duration
Estimate 45-90 minutes per game plus setup time. More fields reduce total duration.
