Each team carries an adult's phone and scans the QR code beside an exhibit. A card opens — no app, no sign-up. The answer is on the label.
Your first 5 players are free, no card. Then $1 a player.
A real card, as a team's phone opens it: a monster, what a win pays and the card it guards. Your own cards ask about your exhibits.
The card at the astrolabe asks what it measured. The phone does not say; the label does. The code hangs beside the object, so finding one is finding the other.
Teams fight the boss in a mini-game on the phone. Its card stays locked until the team has found the sword you wrote into your story, so nobody skips to the end.
You write the questions with the AI assistant you already use — about 30 minutes. Then walk the rooms once and check each answer against its label.
Test the basement gallery for signal before you mount a code there. Codes print on any printer.
Build a trail for freeThe class splits into teams, each with a teacher's or a helper's phone. Joining is a scan and one tick of the terms box, so they are playing once the coats are off.
Teams start at any code and fan out, so the whole class is never standing at the same case.
Points for right answers, treasure and beaten monsters. The leaderboard is live, so the last 10 minutes are a real finish, not a slow walk to the shop.
Your staff do nothing on the day.
