One Game A Week Jam

One Game A Week Jam is a weekly game jam built around making small, finished games quickly. Each week gives you four challenge prompts:

  • Engine
  • Genre
  • Theme
  • Limitation

The goal is to make a game in one week that fits as many of those four prompts as possible. You are encouraged to hit all four, but you are still welcome to submit if your game only uses some of them (or none!). The point is to make something, finish it, learn from it, and keep moving.

This Week's Challenge


You may interpret the prompts creatively. A tiny finished game is better than a huge unfinished one. Scope is part of the challenge!

Rules

  • Start fresh: Your submitted game must be started during the jam period.
  • No completed games: Do not submit a game that was already finished before the jam began.
  • Premade tools are allowed: You may use existing code, templates, plugins, asset packs, fonts, music, sound effects, or other tools, as long as you have the right to use them.
  • Credit your assets: Credit third-party assets where required.
  • No NSFW content: Keep submissions safe for a general audience.
  • No hateful or harassing content: Racism, sexism, homophobia, transphobia, antisemitism, or other discriminatory content is not allowed.
  • No stolen content: Do not use copyrighted material you do not have permission to use.
  • AI tools are allowed: If you use AI in a meaningful way, disclose it on your submission page.
  • Label sensitive content: Please warn players about flashing lights, loud sounds, disturbing imagery, or other accessibility-sensitive material.
  • The host may remove submissions: Entries that violate the rules may be removed from the jam.

What You Can Submit

Submit a playable game, prototype, interactive toy, narrative experiment, or small game-like experience made during the jam. Browser builds are encouraged, but downloads are welcome too.

Your game does not need to be perfect. It does need to be playable enough that someone else can understand what you made.

Ratings use a 1 to 5 star scale.

Spirit of the Jam

This jam is about momentum. Make small things. Finish them. Try weird ideas. Learn by shipping. Some weeks will produce something good. Some weeks will produce a haunted pile of mechanics wearing a menu screen. Both are useful.

Be kind when rating and commenting. Judge games in the context of a one-week jam, not as if they were commercial releases built by a studio with producers, money, and the tragic optimism of a roadmap.
