Title: 6 team, 3 sport round robin
Post by: Billybob on March 16, 2012, 07:23:51 AM

There are six teams playing 3 different sports at the same time and each sport will be a round robin tournament.  While 2 teams are playing one sport, the other four teams will be playing the other two sports. There will be 15 rounds with all 6 teams competing.  For example:Round 1 will be 1 vs 2 , 3 vs 4 , and 5 vs 6.  Round 2 could be 1 vs 3, 2 vs 6 and 4 vs 5, etc.  I need a schedule for all 15 rounds

Thanks

Take a standard round-robin for 6 players (I have used the 'balanced' one you can get by following the schedules link at the top of this page) and then rearrange the order of the three columns, rotating by one place for each block of 5 rounds.  A team's opponents will come around in the same order for each block of 5 so you might like to randomize the order of rounds 6 to 15 to avoid this.

           S1 S2 S3
Round  1: 36 12 45 
Round  2: 62 53 14 
Round  3: 43 25 61 
Round  4: 24 31 56 
Round  5: 15 64 23 

Round  6: 45 36 12 
Round  7: 14 62 53 
Round  8: 61 43 25 
Round  9: 56 24 31 
Round 10: 23 15 64 

Round 11: 12 45 36 
Round 12: 53 14 62 
Round 13: 25 61 43 
Round 14: 31 56 24 
Round 15: 64 23 15
