Welcome! The GMC Jam is a game jam hosted on the YoYo Games Forums, where members can compete to create the best game using GameMaker. Competitors are advised to follow a theme in each jam and must complete their game within the time limit, which has ranged from 3 days to 10 days in the past and currently stands at 4 days.

The theme of each GMC Jam is picked by the winner of the previous jam. In the past there have also been additional handicaps and keywords chosen by joint winners and runners-up.
