Feature looks good. I just need ability to specify who faces who in each round (and do it through the API too!)

They should totally let this be open-source now.. They are not giving any updates for a long time and this answer is the proof. 3 years and a half later, no sign of this functionality.. :/
I mean this tool is very powerful and useful but new things need to come otherwise some other tools will get better.

As far as i know, this isn't open-source. Open-source it would make it live longer, and i'm speaking from a dev point of view.

*Taps Microphone* Is anyone out there? I would gladly support the site with my dollars if this was implemented. But the last response was four years ago...

I want to see that bedore dying

Hi David

Our group will be happy to use Challonge for our gameplays if you support double round-robin for group phase. It would suit us just fine. Is there any chance for seeing that in the near future?
I am looking forward to hearing from you.

perhaps you can do it in a way where the results based on rankings could be then placed into a new linked group.

so lets say you have 24 players that play in a group round robin format.

at the end of that first stage. you set it up so we can just like it does now forwards the number from this stage we specify in this case lets say we specified it like this

1-6 group A
7-12 Group B
8-14 Group C
15-24 group D

those stages could be anything round robin or double/single etc.

Couldn't agree more! We have a double round-robin tournament too that feeds into the seeding for final bracket play. Is there any update? It looks like the last update was in December 2013 :(

Please add this very useful feature!

Please add this soon! I agree with so many others. Looks like it's been on the back burner for a while, what can we do to get it moved to the front. Love this site.

Definitely need this please. Great site.

This is a must... I don't understand why it hasn't been implemented yet.

First, I love this site! We are a small group of volleyball enthusiasts and get together to play for fun. We have used Challonge for several tournaments. With a double round robin option, we would be able to run a league. Using the results to seed an end of season tournament. I know this has been on the back burner for a few years. Sure would love to see it pulled to the front!

We use double round robins in our pool tournaments. Right now I'm doubling up the dates and entering scores as separate sets. It works but would be so much nicer to have each match on it's own line.

To clean up the round robin presentation, you could allow tournament organizers to hide certain rounds, which would help with tournaments that limit the amount of rounds played each week.

I think that we should at least be able to decide how many times each team plays each other in a round robin, instead of just 1 time.

C'mon, add it!

I need this!

Double Round Robin still not here...

What the hell. Posted in 2011 replied to in 2013 and still not a feature in 2015? Is this a matter of forgetting or laziness.

PLEASE ADD THIS FEATURE!!
Double Round Robin are a must for FIFA tournaments
