This is also how Multiplayer works: one code, one city — friends, a class, or a hostel group all play it together, live, collecting into the same city at once.
For teachers, hosts and group leaders: you build the game in your browser. Your group plays it in the app.
You build the game at your computer. Pick places in your city, or set your own. Only you need an account. Your group does not.
Each group builds its part. You split up the places. Each group writes questions for its own places. The other groups don't see them yet. That's the surprise.
You look at everything. Then you say: done! Every question crosses your desk once. Only then does it go into the game.
Your group gets the app and types in the code. One code. No account. No sign-up. Enter the code — and everyone is in the same game.
Now you play outside. You walk to the places. You answer the other groups' questions. At the end, everyone has stamps in their passport.
Where this stands today: the builder is still in internal testing — it does not save your work yet, so we are not linking it here. For a full game day with your group, just get in touch.
