Gamedev.js Jam celebrates Web games - build an HTML5 game within 13 days of the jam on a given theme, it runs between April 13th, 5 PM CET and April 26th, 5 PM CET 2024. Also, there are prizes!

Join the Jam!

Theme will be announced on April 13th. Remember that your entry will be judged based on how well you implement the theme, but you can interpret it however you like.

Join us no matter your skill level - this game jam is a perfect opportunity to create your very first game, or build a prototype for your next commercial hit. Almost two weeks of development time should be more than enough!

You can use #gamedevjs hashtag on Twitter to share your progress, ask for feedback, see what others are building and hopefully help them out if they need it. There's also a Discord server for direct communication!

This Jam is organized by Andrzej Mazur from Enclave Games.


There are optional Challenges in the Jam - entries submitted to those will be judged separately by the panels of dedicated experts, and each offer unique prizes for the best games.

  • To be announced.

You are free to take on any of them, selected few, or even all at once.


There are two levels of prizes: for all the entries, and for given Challenges.

Submitting your entry

Submit an HTML5 game between April 13th and 26th 2024 through the Itch.io platform. It can be a solo submission, or a team effort. You can even submit more than one entry if you want to.

Voting on entries

Voting will be open to all who submitted a game, and will happen via the Itch.io platform for 13 days right after the submission period ends - between April 26th and May 9th. Winners will be announced on May 10th, and challenges on May 11th.

Games will be voted on based on a given criteria: Innovation, Theme, Gameplay, Graphics, and Audio. The Overall ranking will be based on the summary of those.

Following the rules

The short version is: anything that can run on the Web in a browser without extra plugins is considered a valid jam entry. It's highly advised you create new content for the jam - submitting your old demos or already finished projects makes no sense.

If you have any questions or concerns please ask at the Community forums or join our Discord server.
