​Build a playable browser game with AI in one afternoon. Then stay for drinks.

​No prior game development experience required!

​This is a six-hour hackathon for people who want to have fun building a weird, funny and possibly cursed game.

​Use Codex, Claude, Cursor, or whatever AI coding setup you like to design, code, generate assets and ship a small 2D or 3D browser game.

​Phaser, Excalibur.js, Three.js, Colyseus, PartyKit, React, and other web stacks are welcome.

​The only real goal: by the end, your game should run, load, and be playable by someone else.

No pitch decks. Just games.

​🔥 Start faster with the AI Game Jam Boilerplate: a Bun-first multiplayer browser-game starter with Colyseus, Excalibur, React, and built-in AI development skills.

Want a finished example to learn from? Vadim Jam is the complete game built from this stack - study it, remix the ideas, then make your own weird thing.

​🎮 You can build:

• ​A 2D arcade game

• ​A 3D browser game

• ​A strange interactive toy

• ​A chaotic multiplayer game

• ​An AI-powered NPC or game mechanic

• ​A procedural world, level, character, or story system

• ​A game about Romanian public figures, local politics, internet drama, bureaucracy, taxes, or whatever else deserves a health bar - like MTV's Celebrity Deathmatch

​Keep it funny - don’t make us call a lawyer 😅

​🕹️ Format:

• ​Solo or teams of 2–3

• ​Six-hour build sprint

• ​Final demos at the end

• ​Five-minute demo per project

• ​Afterparty with drinks after the demos

​🚀 Submission requirements:

• ​A playable game, deployed or runnable locally

• ​A short description of what you built

• ​A note on how AI was used

• ​Optional: GitHub repo, screenshots, or gameplay recording

• ​Bonus points if you publish your game on itch.io!

​🏆 Judging criteria:

• ​Playability: does it actually run?

• ​Fun: is there a clear mechanic or interaction loop?

• ​Creativity: is the idea fresh, funny, strange, or surprising?

• ​AI leverage: did AI meaningfully help you build faster or better?

• ​Completeness: did you ship something coherent in six hours?

​👾 Who should come:

• ​Developers curious about AI-assisted game development

• ​Designers and product people who want to prototype interactive ideas

• ​Indie game builders

• ​AI builders who want a more creative hackathon format

• ​Curious beginners who are technical enough to contribute hands-on

​🎒 What to bring:

• ​Laptop

• ​Charger

• ​Goodwill

​You do not need a finished idea before arriving.

​After the demos, we’ll keep going nearby or on-site for drinks.
