Great games come from vision and iteration, not from who hand-typed every line or hand-drew every pixel. Build an immersive world with whatever gets you there: AI art, AI audio, coding agents, asset packs, your own hands, or all of it at once. Bring the experience. We judge that, not your process.

✦  The Deal

  • 72 hours. The theme drops the moment the clock starts. Build, ship, done.
  • Any tool, no apologies. Generative AI, coding agents (Claude Code, Cursor, Copilot), asset packs, any engine.
  • Solo or team, any size. A browser build is encouraged, so more people can play and rate you.

✦  How Entries Are Judged

Voting is by participants and invited judges, never the public. Four things, each rated 1 to 5:

  1. Immersion. Did it pull you into its world and hold you there?
  2. Player Experience. Was it fun and satisfying to play, moment to moment?
  3. Cohesion & Craft. Does it hold together as one finished, consistent piece?
  4. Theme. How well does it use the theme revealed at kickoff?

✦  Schedule

  • Fri Sep 11, 6PM · Submissions open and theme reveal

✦  The Rules

Disclose your tools

List what you used on your submission page (for example Claude Code, Midjourney, Suno). If you used no AI tools, say so. It is a badge of honor here, not a confession. No disclosure means no entry.

Use assets you are allowed to use

You are responsible for your tools' terms and any third-party claims on what you generate. No trademarked or infringing content.

You keep 100% of your work

We will not train any model on your submission. We may feature entries to promote the jam.

Show craft

Obvious zero-effort, single-prompt dumps may be removed. The bar is a real experience, made well.

Be decent

This is a build-cool-stuff space. Tool-shaming and flame wars get moderated.

Theme drops Friday Sep 11 at 6PM BST (17:00 UTC). Hit Join jam at the top of this page to get in.
