It seems that the facility we play in messed up the scheduling for our 12 teams.  I hope someone can give me 6 more weeks of scheduling without playing anyone twice with the first 2 games already scheduled.

Here are the first 2 weeks of games (8 games in our season with 12 teams involved)

week 1:  4v6, 11v12, 7v10, 5v9, 2v3, 1v8

week 2:  2v9, 7v12, 3v5, 1v11, 4v8, 6v10

Thanks for all of your help,

Mike

It's possible to complete the full 11 week all-plays-all round robin schedule from the initial two weeks.  Below there is an example which also has venue balance - no team more than twice in any single column.

Hope that helps.

Ian.
