Brief

Edwin Arbus and @levelsio are running the 2026 @cursor_ai Vibe Coding Game Jam (start 3 Apr 2026, deadline 1 May 2026 13:37 UTC) with $20k/$10k/$5k prizes. Rules require ≥90% AI-written code, web-accessible free play, and prefer Three.js. Edwin spotlights Cursor 3 and Composer 2 tooling and showcases Cursor-made games by four creators.

Why it matters

2026 Vibe Coding Game Jam (announced by @levelsio, promoted by @edwinarbus) starts 3 Apr 2026 and ends 1 May 2026 at 13:37 UTC; cash prizes are Gold $20,000, Silver $10,000, Bronze $5,000; sponsors include @boltdotnew and @cursor_ai.

Key details

  • Entry requirements: at least 90% of code must be written by AI; projects must be started on/after the announcement (3 Apr 2026), be web-accessible without login and free-to-play, one entry per person, paste the HTML in the Google form; multiplayer preferred and Three.js is recommended; no heavy loading screens.
  • Edwin promotes Cursor tooling—Cursor 3 (built-in browser, image generation, cloud agents for playtesting) and Composer 2 (fast with Three.js)—and cites games made with Cursor by @startracker, @DannyLimanseta, @ghosttyped, and @chongdashu; he claims even Rockstar developers are using AI to build faster, more complex games.
Cleaned source text

Along with @levelsio, we’re looking for the best games you make with AI. More in his tweet below.

Cursor 3 has a built-in browser, image generation, and cloud agents that can playtest, while Composer 2 is fast with Three.js. Great for building games!

Even developers at Rockstar are using AI now. Games can be built faster, made more beautiful and complex, and created by more people. It's surprisingly easy if you have no experience. The games shown below were already made with Cursor by @startracker, @DannyLimanseta, @ghosttyped, and @chongdashu.

Show us what you can build! Can't wait to see your submissions.

Me, @s13k_, and I will ask some real game dev and AI people to jury again too

It will be interesting to see the difference in quality with last year, and the Vibe Jam can be kind of like a fun benchmark for AI coding seeing it close in on real commercial games I think
