Rules every game follows

Every game made from the starter keeps these rules. Claude knows them from the starter’s CLAUDE.md. This page is for grown-ups.

1. Nothing from other websites. There are no ads and no tracking. The game loads no pictures, sounds, fonts or code from somewhere else. Everything it needs is inside it. The only connection out is playing together.
2. No links out and no pop-ups. A game never sends a child to another website. “← Arcade” goes back to the arcade.
3. No chat. Players share their player name and nothing else they type. Messages between devices carry the game, nothing more.
4. Playable by touch and by keyboard. Every button is big enough to tap. Every action has a key too.
5. Calm when asked. If a device is set to reduce motion, the game has no shaking, flashing or spinning.
6. Readable. Text is at least 16 pixels, with strong contrast.
7. Kind with data. A game saves only what it needs. It saves only in the browser, and only through the kit.
8. Tested before it is published. Every change runs the tests and the build. If either fails, nothing goes live.

Enforced and not enforced

Rule 8 is enforced. GitHub will not publish a game whose tests fail. The other rules are what Claude is told and what the starter does. Nobody checks another family’s game. That is why the arcade says: only add games from people you know.
