Code your own games.

How it works
Three steps from idea to a game your friends can play.
1. Code it
Pick a quest and change the code. Tiny commands like stamp('dragon') do big things.
2. Run it
Press Run and your game appears right next to your code. Try, change, run again!
3. Scan it
Every game gets its own QR code and link. Scan it with a phone camera to play anywhere.
