An example schedule for 8 teams is:
week 1 | week 2 | week 3 | week 4 | week 5 | week 6 | week 7 | ||
period 1 | 0 v 1 | 0 v 2 | 4 v 7 | 3 v 6 | 3 v 7 | 1 v 5 | 2 v 4 | |
period 2 | 2 v 3 | 1 v 7 | 0 v 3 | 5 v 7 | 1 v 4 | 0 v 6 | 5 v 6 | |
period 3 | 4 v 5 | 3 v 5 | 1 v 6 | 0 v 4 | 2 v 6 | 2 v 7 | 0 v 7 | |
period 4 | 6 v 7 | 4 v 6 | 2 v 5 | 1 v 2 | 0 v 5 | 3 v 4 | 1 v 3 | |
One extension of the problem is to double round robin tournaments in which each team plays every other team (as before) but now both at home and away. This is often solved by repeating the round robin pattern, but swapping home games for away games in the repeat.
