🎃 31WEEN — Halloween Game Jam 2026

Create Something Wicked.

Welcome to 31WEEN, an international online game jam celebrating Halloween through games, creativity, and imagination.

From October 10 to October 25, 2026, developers from around the world are invited to create their own Halloween-inspired game. Whether you're an experienced indie developer or making your very first game, you're welcome to participate.

👻 The Challenge

Create a game inspired by Halloween. Horror, mystery, monsters, supernatural events, haunted places, dark comedy, spooky adventures — the choice is yours.

🎮 Who can participate?

Everyone.

You can participate alone or as a team. Beginners are welcome, and your game doesn't need to be huge or technically complex. A creative and fun small game can be just as exciting as a large project.

🌍 International & Online

31WEEN is completely online and open to creators from anywhere in the world.

🏆 The Award

At the end of the jam, one game will receive the official:

🏆 31WEEN 2026 — Best Game

The winner will be announced publicly on Halloween, October 31, 2026, with a special congratulations and showcase of their game.

There is no cash prize and no physical prize — the award is an honorary recognition for the creator and their game.

🗓️ Important Dates

October 10, 2026 — Jam begins

October 25, 2026 — Submission deadline

October 31, 2026 — Winner announced

So sharpen your ideas, turn off the lights, and start creating.
