Thanks to the math skills of Alpha I'm pleased to announce the Round Robin tournament format now supports 3-player games. Hopefully this will be extended to 4 player games at some point in the future.

ps you may need to hit F5 (refresh) to get the updated code on the Create Tournament page.

Awesome, I am glad that the code will work here.

Mongrel and I have been discussing the problem of four player round robin scheduling and it turns out that my initial hope that ideas would easily extend was wishful thinking. It is a harder problem than I had thought, but I will spend some time on it later this summer if Mongrel doesn't solve it without me.

Thanks to Mongrel for the ideas that lead to the implemented code for three player round robin scheduling. This was a team effort and Mongrel deserves credit as well.

Has anyone started one of these? I am interested to see what Tom has done with the output I gave him.

I'll try a 3-legged race.

Hmm. For 15 players, it says there will be 14 rounds in the tournament in which everyone plays. Should be 7.

Good point. What's the calculation for the number of round for n players?

Each round you face 2 new opponents, n-1 opponents (everyone but you), so (n-1)/2 rounds

Perfect thanks.

4 player scheduling is hard, but partial solutions are available.

We could hard code known solutions. Next week at the earliest.
