I'm hosting a 9 event tournament (bocce ball, horseshoes, crouqet golf, etc.)  this Saturday with 36 players.  The various events will consist of 4 players each.  The goal is for each player to play the 9 different events (without playing any twice) while playing with as many different combination of players as possible.  Can someone please help me with this so I can set-up a bracket as early as I can.  Any assistance would be greatly appreciated.  Thanks!!

Duke,

I think you have too many constraints to get a good solution, or at least I don't know how to find a good solution with this many constraints.  The schedule below will at least make sure that everybody gets to play all games once, however the pairwise balance, or social mix within the foursomes, is compromised in order to achieve this.

Below I have used "R" to represent the rounds, "G" for the 9 type of game and 1 to 36 for the players.
Hope that helps,

Ian.
