We will be having a dedicated js13kGames Challenge in the upcoming edition of Gamedev.js Jam 2024 that starts April 13th with the chance of winning thirteen unique Badlucky t-shirts!

Celebrate the thirteenth edition of the js13kGames competition by following its rules: create a web game that fits into a 13 kilobyte zip package!

The fifth edition of Gamedev.js Jam will now have an optional opportunity to exercise your js13k-fu skills before August. Instead of a whole month you’ll have only 13 days though, so keep that in mind. You will, however, have the chance to win the cool swag: Badlucky t-shirts.

Zip sizes will be validated outside of Itch to make sure there’s no cheating, since Itch itself don’t have such functionality. The top13 winning games will be picked by filtering the scores of the best overall entries based on the js13kGames challenge checkbox selected.

Have any questions? Join js13kGames Slack or visit js13kGames channel on the Gamedev.js Discord server. Good luck and have fun!
