Game Jams are a friendly competition, where participants make a game within the time limit and under certain rules. How to participate is to wait until the theme is announced, then use the theme to brain storm and make a game within the time limit. This is all about having fun and putting your skills to the test within a friendly environment, among great people.
Following all rules will grant you eligibility for prizes and honorable mentions.
I suggest practicing in the meantime. We also offer Practice Circles connected to each Beginners Circle. This would be the perfect place to get the same treatment, without the rules or prizes.
Excited to see what you make for the game jam. Good luck!
