For the last two days of September, September 29 – 30, you vibe out an AI game: code, art, music, voices, 3D, all of it. Then you ship it as a mobile resolution web game here on itch.io.
🎯 Theme
The theme is announced here and on Discord the moment the jam starts. Until then, get your tools ready.

📱 Format
Every entry must meet these three requirements:
- Mobile portrait. Your game runs at a portrait phone resolution, for example 720×1280 or 1080×1920, with touch controls.
- Web build. Export to HTML5 and upload it to your itch.io game page so it plays in the browser. No downloads.
- Made with AI. If you're looking for tool suggestions, check out our recommendations.

📏 Rules
- Make it during the jam. Design, code and content are created inside the jam window. Pre-made engines, templates, asset packs and AI tools are fine; a game you started before the jam is not.
- Portrait web build. Entries that cannot be played in the browser in portrait on a phone will not be rated.
- Credit your tools. List every AI tool you used, and the humans on your team, on your game page.
- Respect licences. Only use assets you have the right to use. Asset packs, public-domain material and AI output are fine within their licences.
- Keep it safe. No hateful content. Add a content warning on your page if your game has anything not suitable for everyone.
