Two days. One game. Any AI tool. Code, art, music, voices, 3D. Enter solo or as a team and ship a browser game to itch.io that plays on phones.
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.

Provisional combined rankings
Judges rated Fun, Visual Appeal and Theme Following on itch.io. Fun was Primary, so itch.io's main ranking is Fun-only, with no Overall ranking. Separate Visual Appeal and Theme Following views are available. This page averages the three displayed adjusted Score values equally and sorts before rounding combined scores for display. Using the Score column rather than Raw Score preserves itch.io's adjustment by median rating count. Official ratings remain unchanged.
