🎯 The Theme is: Reuse

Create a game inspired by Reuse. Interpret it however you'd like—recycling, reusing mechanics, time loops, second chances, or something completely unexpected.

💎 The Bonus Gem is: Bouncy

Incorporate Bouncy into your game for a bonus point. This can be literal or abstract: bouncing physics, trampolines, energetic music, a cheerful character, rubber objects, and more.

💎 The Gem Jam

Welcome to The Gem Jam, a weekly game jam focused on creativity, discovery, and building great games together.

Whether you're a first-time developer or an experienced creator, everyone is welcome.

📅 Schedule

Starts: Friday, 12:01 AM

Ends: Sunday, 11:59 PM

A new theme is announced at the beginning of every jam.

After submissions close, games become available to discover through Gemion throughout the following week.

🎯 Theme

Theme will be revealed at start of game jam.

Bonus theme will also be revealed then.

📥 How to Submit

1. Create your game during the jam.
2. Upload it to itch.io.
3. Copy your itch.io page link.
4. Submit the link through Gemion before the deadline.

Gemion is a discovery platform, not a hosting platform. Your game remains on itch.io while players discover it through Gemion.

⭐ Judging

Each game is rated from 1–10 in the following categories:

• Fun
• Creativity
• Theme
• Polish
• Replayability
• Overall Impression

Your final score is the average of these categories.

💎 Bonus Gem

Every week includes a hidden bonus challenge.

Complete it creatively to earn +1 bonus point.

The Bonus Gem is completely optional—but it's a fun way to make your game stand out.
