This jam is now over. It ran from 2026-09-18 09:00:00 to 2026-09-30 09:00:00. View 10 entries

The theme is — Small Creatures


⚠️ First round quirks
Registration closes on September 18, 2026, because due to how this first round is configured on itch.io, new participants cannot join once the development period begins.

You can start developing your game right away and submit it later during the round.

This is only a limitation of the first round. Future rounds will open for registration around the middle of the previous month.

One Month — One Game

One Month One Game is a recurring game development challenge built around a simple idea:

Make one game every month.

Not a masterpiece. Not your dream game. Not a project that stays in development forever.

A finished, playable game.

The goal of the challenge is to practice finishing projects, experiment with new ideas, learn faster, and gradually build a collection of released games.

How it works

Every month is a new round.

Join the round, make a game during the month, publish it, and submit it before the deadline.

Then the next month starts and we do it again.

There is no requirement to make something huge or technically impressive. Small games, prototypes, experiments, weird ideas, jam-sized projects and tiny incremental games are all welcome.

Scope is your friend.

A 10-minute game that is actually released is much more valuable here than an ambitious project that never leaves your hard drive.

This is a challenge, not a competition

One Month One Game is primarily about consistency and finishing games.

You don't need to compete with other participants. You don't have to chase ratings or make the most polished game in the jam.

Your main opponent is unfinished-project syndrome.

Try something. Finish it. Release it. Learn from it. Make the next one better.

Who can participate?

Everyone.

You can work:

  • solo or with a team;
  • with any engine, framework or technology;
  • in any genre;
  • with 2D, 3D, text, pixel art or whatever else works for your idea;
  • as an experienced developer or as someone making their first game.

The challenge is also friendly to AI-assisted development. Tools are tools — what matters is that you actually make and finish the game.

Languages

The challenge is international and English is used as the primary language. 

But we comfortable with the other languages.

One challenge, multiple platforms

One Month One Game is intended to be more than a single itch.io jam page.

The project has its own website that tracks rounds and is being built to support game submissions from multiple platforms.

🌐 Project website: https://scrabyq.github.io/one-month-one-game/

The website and its infrastructure are open source.

💻 GitHub repository: https://github.com/ScrabyQ/one-month-one-game

Issues, suggestions and contributions are welcome.

The important part

Don't spend the entire month searching for the perfect idea.

Pick something small enough to finish.

Make it.

Publish it.

And next month — make another one.
