What you need to make a game

You are going to make a game at your own web address. Anyone you send the link to can play the game. They can play together from different homes.

Who does what: The child has the ideas, says what to change, and plays. The grown-up handles the accounts, types, and presses the buttons. An AI helper named Claude writes the code.

Time: about an hour the first time. After that, as long as you like.

What you need

Section titled “What you need”
  • A computer with a web browser. A tablet or phone works too, but a computer is easiest the first time.
  • A GitHub account (free) at github.com. GitHub keeps your game’s code and puts it on the web. You must be 13 or older to have an account. For a younger child, it is a grown-up’s account.
  • Claude, Pro plan or higher, at claude.ai. It includes Claude Code, the AI helper this guide uses. The account holder must be 18 or older.

Steps to your first game

Section titled “Steps to your first game”
  1. Start from the template: your game’s own web address, in ten minutes.
  2. Connect Claude to your game: once, on the web.
  3. Ask for your first game: one sentence, then ask, merge, play.
  4. Improve your game: small asks, played after each.
  5. Play your game with friends: up to four devices, in other homes too.
  6. Add your game to the arcade: a tile on each of the family’s devices.

If something goes wrong: Fix common problems.
