Title: Mah Jongg Tournament
Post by: Mah_Jongg_Maven_NJ on September 01, 2011, 08:57:28 PM

4 to a table
9 tables
9 rounds
I want everyone to play with each other at least once
Does anyone have a workable solution?  Thanks.

With 9 rounds and 3 opponents per round, each player can play with, at most, 27 out of the 35 possible opponents.

In fact it's possible to play up to 11 rounds keeping all the opponents different.  So simply discard any two of the rounds in the schedule in thread "36 players, 9 tables".
