Free for a birthday party - no card, no subscription.

Outdoor treasure hunts, played on their phones

A trail of stations in the park or the woods, a puzzle at each, a villain who writes to the children, a clock that hints cost time from - and a treasure at the end.

You write the game here, print its cards, and send the players one link. They play on any phone, without an account; you watch and steer from the live console.

Or let an AI assistant write the whole hunt for you - the story, the stations, the hints - straight into your account.

How it works

Build the trail, hide the clues, start the clock. Every station the children solve reveals a letter; the letters tell where the treasure is.

Step 1: the stations on a map, with a task at each 1. Build 1 2 3 🪞 mirror letter 📻 Morse word 🔑 the hidden key
Step 2: the phone leads the team to the place and shows the task 2. Play ⏱ 42:17 ≈ 120 m ⬆️ We are here! 💡 hint −2 min 💬 the villain
Step 3: the letters give the password, the password reveals the treasure 3. Find P I A N O …right next to the piano! 🏆

Use it for

A birthday in the park A camp, a scout troop, a school trip A family walk that is suddenly a mission A city trail for grown ups, too

A phone is the whole kit

GPS navigation, warmer and colder, a compass, a mirror, a Morse receiver, a red filter that reveals invisible ink - every tool is in the browser. Nothing to install, nothing to charge but the phone.

You are the villain

From the live console you see every team's clock and station, answer their calls for help as the villain, give time back, mark a station solved when the GPS would not. The game is yours to steer.

Written with an assistant

Share a game with a friend to view or edit, copy one for the next group, or connect an AI assistant: it reads and writes only the games you open to it, every change is marked and can be undone.
