## Rules

- **Who**: any creator with a Star account.
- **What**: any game **created and published on Star during the jam window** (May 1 to May 25). Pre-existing games don't qualify, the spirit of a jam is everyone starts from scratch.
- **How**: when you hit Publish, flip on **Enter the Star Spring Jam**. Or enter anytime from this page using the Submit buttons under "Your games this jam".
- **Multiple entries**: yes, submit as many as you want.
- **Iterating**: keep building on Star anytime. The judged version is the latest published version at the moment of judging, so polish it as long as you like.

The jam runs in our [Discord](https://discord.gg/Wt2tuy5Rzh). That's where the chatter, peer feedback, and live submissions happen. Come hang.

## Rules

- **Who**: any creator with a Star account.
- **What**: a **multiplayer** game published (or republished with real changes) during the jam window (July 10 to Sunday night, August 2). Any genre, co-op or versus. Beating your friends counts.
- **How**: build it, hit Publish, and flip on **Enter the Summer Party Jam**. Or submit anytime from this page using the Submit buttons under "Your games this jam".
- **Templates**: fork the 2D arena or the 3D FPS below and make it yours. The netcode already works, so your credits go into your game, not into wiring. Judging rewards what you built, not what you started from.
- **Judging**: winners are picked at the end of the jam. Entries get played live, with real people, at Discord play nights announced through the jam window. Better with friends wins.
- **Multiple entries**: yes, submit as many as you want.
- **Tip**: multiplayer is heavy lifting for Star. Pick the Pro or Ultra model for it. It does a lot better and saves credits on retries.
- **New and honest**: multiplayer is in beta. If a room acts weird, report it in [Discord](https://discord.gg/Wt2tuy5Rzh) instead of spending credits on repeated fixes. Platform bugs are on us, and we'll credit back what you spent chasing one.

The jam runs in our [Discord](https://discord.gg/Wt2tuy5Rzh), in #summer-party-jam. Play nights are where the playing and the friendly trash talk happen. Come hang.
