AI Game Jams: How to Enter One with a Game You Made with AI

An AI game jam is a short, themed game-making event where entrants are allowed, or expected, to use AI tools for code, art, or audio. To enter one with an AI-made game, pick a jam whose rules welcome AI, scope a game you can finish in the time window, build it around the theme, and submit a browser-playable build before the deadline. On Fifth Door there is a weekly jam you can enter straight from your editor.

This guide covers how to find a jam that allows AI, how to plan a jam game, and how to enter the Fifth Door weekly jam.

Do game jams allow AI?

Some do, some do not, and the rules differ. Before you start:

• Check the AI rule. Some jams ban generative AI entirely. Others welcome it, and some exist specifically for AI-assisted games.
• Check disclosure. Many AI-friendly jams ask you to list the tools you used on your submission page.
• Check the format. Browser-playable, a specific screen orientation, or a specific platform for submissions.
• Check timing. Most jams run from 48 hours to a couple of weeks, with the theme revealed at the start.

When in doubt, read the jam page and ask the organizers. Breaking the AI rule is the fastest way to get an entry removed.

Where can you find AI game jams?

itch.io lists many jams, and several recurring ones are built around AI-assisted browser games. Search the jam listings for "AI" and filter by dates. Communities for the tools you use (Claude, Cursor, and other coding agents) also announce jams.

Fifth Door runs its own weekly jam with a theme and a deadline. Because it is weekly, there is always a next one, which makes it a low-pressure place for a first jam.

How do you plan a jam game you can actually finish?

Jams reward finished, playable games over ambitious broken ones. Plan like this:

1. Read the theme and brainstorm for ten minutes. Write five ideas. Pick the one with the clearest single mechanic.
2. Scope to one core loop. One action, one goal, one fail state. See AI game ideas for scoped examples.
3. Get a playable version in the first hour or two. Use Fifth Door create or a coding agent with a single tight prompt.
4. Spend the middle on feel. Controls, feedback, difficulty curve.
5. Stop adding features well before the deadline. Use the last stretch for a title screen, instructions, a cover image, and testing on a phone.

The theme should change how the game plays, not only how it looks. A "pumpkin" theme with a pumpkin sprite on a generic runner is weaker than a game where the pumpkin's weight changes the jump.

How do you enter the Fifth Door weekly jam?

The jam runs through the Fifth Door MCP server, so you can do it from Claude Code, Cursor, or Codex:

1. Install the MCP server and sign in. Steps are in how to publish a vibe-coded game.
2. Check the jam. Ask your agent to run list_jams. It shows this week's theme, deadline, and entry count.
3. Build and publish. Publish the game; it starts unlisted.
4. Make it public during jam week. Entries must be public games that first went public during that jam's week, so do not make an older game public and enter it.
5. Enter. Ask your agent to run enter_jam with the game. You can withdraw it with withdraw_from_jam while entries are open.

Going public also lists the game on Discover and queues a short gameplay preview for its card if it does not have one. You can also record one with generate_game_preview.

What tools help most in a jam?

• A coding agent for the game itself. See how to make a game with Claude Code.
• Asset generation. The Fifth Door MCP server can generate images, characters with animations, music, sound effects, and voice lines into your project, on a daily budget per account. Spend that budget on the assets players see most.
• Platform services if the theme calls for them: a daily twist, a leaderboard, or a room for friends. See how to add a leaderboard to a browser game.

What makes a jam entry stand out?

• The theme is part of the mechanic
• The first ten seconds explain the goal without text walls
• It works on a phone if the jam is browser-based
• It has a real ending or a score to beat
• The cover art has the title in it

Judging categories vary by jam, but fun and theme use show up almost everywhere.

Common mistakes

• Picking an idea that needs three systems to be fun
• Building art before the game is playable
• Submitting in the last minutes and finding a broken build
• Ignoring the AI disclosure rule
• On Fifth Door, entering a game that went public before jam week

FAQ

What is an AI game jam?

A time-limited, themed game-making event where using AI tools is allowed or expected. Entrants build a small game around the theme and submit it before the deadline.

Can I use AI in any game jam?

No. Rules vary, and some jams ban generative AI. Read the rules and disclose your tools when asked.

How do I enter the Fifth Door jam?

Install the Fifth Door MCP server, check the week's theme with list_jams, publish your game, make it public during jam week, and enter it with enter_jam.

How long is the Fifth Door jam?

It runs weekly. Check the current deadline with list_jams.

What if I do not use a coding agent?

Build the game in create to practice jam scoping. Jam entry itself runs through the MCP server.

Enter this week

Install the Fifth Door MCP server, run list_jams to see this week's theme, build one small game around it, make it public, and enter. Then play the other entries on Discover.
