Prerequisites
How to Solve Round Robin Tournament Problems
Step 1: Identify number of teams (n)
Step 2: For single round-robin, total matches = n(n-1)/2
Step 3: For double round-robin, total matches = n(n-1)
Step 4: Matches per team = n-1 (single) or 2(n-1) (double)
Step 5: Number of rounds = n-1 if n even, n if n odd (single round-robin)
Step 6: Answer based on specific question
Example Problem
Example: 8 teams play a double round-robin (home and away). How many total matches? Solution: Step 1: n = 8 Step 2: Double round-robin matches = n(n-1) = 8 × 7 = 56 Answer: 56 matches
Pro Tips & Tricks
- Single round-robin: total matches = C(n,2) = n(n-1)/2
- Double round-robin: total matches = n(n-1)
- Each team plays n-1 matches in single round-robin
- Number of rounds = n-1 for even n, n for odd n (single round-robin)
- Home/away fairness: each team gets equal home matches in double round-robin
