Most fantasy leagues have more regular-season weeks than a single round robin needs. Twelve teams meet everyone once in 11 weeks, which leaves 3 weeks over. The fair way to fill them is to keep the round robin intact and repeat a few early weeks, so every team has the same opponents except for the same 3 rematches.
Make my league schedule (paste your team names, pick the weekday, tick double round robin, set Rounds to play to 14)
Teams: Ace, Bolt, Colt, Dash, Echo, Fox, Gale, Hawk, Iris, Jinx, Kite, Lynx. Settings: double round robin, Rounds to play 14, Thursday weeks. The tool plays the 11 weeks of a full round robin and then replays weeks 1 to 3 with home and away swapped (home and away do not matter in fantasy; the tool still keeps them even).
| Weeks | What happens | Games per team |
|---|---|---|
| 1 to 11 | Every team meets each of the other 11 teams once | 11 |
| 12 to 14 | Weeks 1 to 3 are repeated | 3 |
| Total | 66 different pairings, 18 of them played twice | 14 |
Each team has exactly 3 rematches, and the shortest gap between a pair's two games is 11 weeks. A separate test rebuilds this schedule from the same code the tool runs and checks every number above.
Play one full round robin first: 12 teams need 11 weeks so everyone meets everyone once. Then fill weeks 12 to 14 by repeating the pairings of weeks 1 to 3. Every team ends with 14 games, 11 different opponents and exactly 3 rematches, and no team plays two games in a week.
Random draws let one team face the league's best three times and another face the worst, and nothing stops a pair meeting four times. A round robin makes the opponents equal for everyone; only the 3 repeat weeks differ, and they are the same rounds for every team.
Repeating the first rounds in the last weeks keeps the gap between a rematch and its first meeting at 11 weeks, the longest possible with this plan, so rematches do not feel back to back. Another common choice is to repeat divisional or rival pairings, which this tool leaves to you.
Yes. Enter the team names, pick the weekday, tick double round robin and set Rounds to play to your regular-season weeks. A 10-team league with 13 weeks gets 9 unique opponents and 4 rematches; a 14-team league with 13 weeks is just 13 games, a single round robin.
