Title: Yard Games Tournament
Post by: YardGamesCo on February 12, 2025, 11:52:34 AM
Hey,

Not sure if this one is possible, my inclination tells me no, but here goes.

I have 6 different games being played. I have 24 teams.

I would like to break the teams into groups of 4 and have a round robin at each game, but id like the grouping to be different for each game.
So each team would play a total of 18 games(a 3 game round robin of each) by the end.

Is it possible to do this with out a team playing a game more than once or repeating opponents?

There is an old Excel file called foursome-tournaments-v4 in this thread (https://www.devenezia.com/round-robin/forum/?topic=1115) that you can download if you are logged in.  This will give you a solution for the related problem of 20 teams in 5 rounds with 5 games, but unfortunately I don't think there is a solution for 24 teams, the most you can manage is the 3 rounds of play shown.  Note that these schedules involve dividing the teams into 4 sub-groups, but you don't have to tell the players about this.

Thank you Ian!

For someone who is both a math lover and event nerd, this forum and what do are just incredible.

What would be the best way to fill in the remaining three rounds with as few repeats as possible?

Any suggestions?
