10 Teams/3 Courts

[scourge22]

I took your 10 team round robin format and spread it over 3 courts for a volleyball tournament.  It seems to work fine.  Is there another way to accomplish this?

I assume you have to split each round into two halves: three games in the first and the last two in the 2nd half and repeat eight more times.  Are there any special requests such as keeping the number of times a team moves from the 1st to 2nd half (or vice versa) to a minimum?

Nothing other than everyone plays each other once.  It's a 1 day multi-team scrimmage.  I usually have either 10 or 12 teams with 3 courts available.
   Thanks,

One of these should do the trick.  The first three columns would be in the 1st half of each round.
