gm(48) is a quarterly game jam held by the community of /r/gamemaker, in which the participants use the integrated development environment GameMaker to create games in a 48 hour period. At the start of every quarter, two 1 week long rounds of voting period occur so that the community can vote for the jam's theme.
To participate in gm(48), you must create your game using GameMaker and upload it to this site within the 48-hour period. No sign-up required.
It's that easy, but in order to encourage community involvement and provide a pleasant experience for everyone, we have a few rules:
We encourage participants to use any and all tools at their availability, as long as the code and execution is done in GameMaker, and we require participants to list any extensions or engines used.
Every participant that wishes for their game to be eligible to win must submit it to the gm48.net website before the end of the 48 hours allotted. After the 48 hours, there will be a short phase of internal review and management, after which we open up for rating.
No participant will be allowed to update their submitted game entry for any reason whatsoever after the 48-hour period has ended. Bugs, mistakes and any other errors present in the submitted game entries are considered a crucial part of the rating procedure.
Every game submitted is rated in 7 categories on a 0-to-10 point scale:
In order to win, you must achieve the highest average sum of all categories.
