Title: 9 players 2 games
Post by: gamingharry on June 19, 2014, 05:31:11 PM

Hi All, whats a decent schedule for 9 players to play 2 games concurrently (one with 5 players, one with 4) where everyone meets each other once.

It may not be possible to have a decent schedule.

   (8  7  4  3  9)  (1  6  2  5)
   (9  8  5  1  7)  (2  4  3  6)
   (7  9  6  2  8)  (3  5  1  4)

Above, everyone meets each other at least once.  But note the following groups play three times:
                                                                                                                
(1 5)                                                                                                                                  
(2 6)                                                                                                                                  
(3 4)                                                                                                                                  
(7 8 9)
