Jams updated: judge feedback, manual ranking, locked uploads

In today's update, we've got more tools for game jam hosts with support for judge feedback, custom ranking, and file locking. If you weren't aware, was the first site to let you instantly host a game jam. Read more in our hosting a game jam guide.

Anonymous judge feedback

A while back we added judges to jams to let hosts elect special individuals that could rate entries. In the past, if a judge wanted to give personal feedback, they could leave a comment and their message would be marked JUDGE. This doesn't work for all jams though. If a judge needs to give honest feedback then it might not be helpful to have their name and a reply button associated to what they have to say. 

All judges now get a new field on the jam's submission page during the rating period that lets them write in feedback. This works quite a bit differently than comments:

  • Feedback can always be left, even if comments are disabled
  • Feedback appears in a special area on the entries page, above the comments
  • Feedback doesn't appear on the game's rating page until after the voting period has ended
  • Feedback is anonymous, doesn't have a reply button, and it shown in a random order when more than 1 judge has posted

We hope this makes it easier to host jams where having anonymous feedback is a critical part of the submission and ranking process. You can see an example of judge feedback on this submission page: YOMOTSU

Judge feedback is automatically available for any jam that has a rating period, no additional options need to be enabled.

Manual ranked criteria's voting criteria tool has always let you easily create a community voting system based around the criteria that is relevant to your jam. When we added judges we made it possible to restrict the voting to only judges. This was a step in the right direction, but not flexible enough for when people want both a community rating and a judge rating. 

We've added a new Manually ranked option when creating criteria. A manually ranked criteria can have the result order manually specified. You just need to list out the game pages and their rank. It's not necessary to rank every submission, feel free to list the top 10, 20, etc. Just like voted ranks, manual ranks can also share the numerical place an entry comes in. For example, you can have two entries share 1st place if there was a tie.

You can choose how a criteria is ranked when creating it on the jam's edit page. Manually ranked results will only appear after the rating period is over. If you don't add them in time, then they'll appear as soon as you add them.

You can see an example of a manually ranked criteria on the Indie Game Maker Contest 2017

Locked uploads

Up until now, jams on generally have used the honor system to make sure people weren't changing their submissions during the rating period. For jams where prizes are involved, it can be pretty critical to enforce the submission rules. Although it's technically possible to check the upload dates, that isn't practical. Hosts can now use the new locked uploads option to prevent submitters from updating or adding new files to their pages during the rating period. Submission owners can continue to update the page's design and description during the rating period though.

The lock only takes affect during the rating period, after the jam has ended submission owners are fee to release their post jam builds. Additionally, if the submission period is still active, files can still be changed. Submitting early will still let you publish updates right up until the deadline.

This option is only available for ranked jams, and you can find the option on the jam's edit page.

Thanks for reading. I hope you enjoyed these updates and look forward for more. If there's anything you'd like to see with our jams system leave a comment.

HOW do you manually rank the games?  You say "You just need to list out the game pages and their rank" but I can't figure out where/how to do this.


After you save the edit page and reload it there’s a link to open up a separate page where you can paste the URLs of the submissions in the order you want to rank them.

Thank you, I did find that — though that page is buggy and does not accept my rankings (already reported separately).


Cool to see that all these tools that were custom coded for the IGMC 2017 jam are now available to all hosts. Thanks again for all the support leafo during the jam, and I hope other hosts find them useful!

What about the ability for jam hosts to turn on a game submission approval? This could help prevent two things:

1) bad users uploading games on every jam in an attempt to farm views.

2) bad users uploading extremely spammy, low-quality and suspicious executables (usually they have nothing to do with the jam's theme)


Definitely, this one is in the queue. I have a few ideas to prevent people from abusing submissions. I think the most effective thing could be having it so that submissions aren't shown until the submission period is over. That way someone who tries to submit to a jam early in an attempt to advertise their game is thwarted.
