# Bridge & other card games/Marathon rotation schdule

Question
This year our Marathon has 17 teams.  We play Sept-April/8 games.
Is there a rotation that would allow each team to play the same number of games?  We can extend it into May and include a Bye. We normally have an even number of teams. It would be OK if one or two teams played an extra game--we could drop the lowest score.  I just can't figure out a rotation.  You help would be greatly appreciated!

Hi,

I assume that the teams will generally play one game each month. With an odd number of teams someone will need to have a bye each month.

Below is a rotation for 17 teams over 8 months.

Month

1     17-2  16-3  15-4  14-5  13-6  12-7  11-8  10-9   Team 1 = BYE
2     1-3   17-4  16-5  15-6  14-7  13-8  12-9  11-10  Team 2 = BYE
3     2-4   1-5   17-6  16-7  15-8  14-9  13-10 12-11  Team 3 + BYE
4     3-5   2-6   1-7   17-8  16-9  15-10 14-11 13-12  Team 4 = BYE
5     4-6   3-7   2-8   1-9   17-10 16-11 15-12 14-13  Team 5 = BYE
6     5-7   4-8   3-9   2-10  1-11  17-12 16-13 15-14  Team 6 = BYE
7     6-8   5-9   4-10  3-11  2-12  1-13  17-14 16-15  Team 7 = BYE
8     7-9   6-10  5-11  4-12  3-13  2-14  1-15  17-16  Team 8 = BYE

After 8 months there will be 8 teams (1-8) that have only played 7 games. I might suggest that these teams play each other in May. The four matches could be 1-2, 3-4, 5-6, 7-8. As a result, every team will have played 8 games against a different opponent.
