# Your phone becomes your investigation notebook.

Choose a trail, form your team and follow the guide from place to place. Each stage reveals a riddle, challenge or detail to observe.

## From your first choice to the final secret

1. **Choose your trail** — Filter adventures by location, duration, difficulty, theme or transport. Each page gives you the practical information you need.
2. **Name your team** — The team joins from one phone. Free content can be started without an account; the trail page tells you whether a sign-in, purchase or access code is required.
3. **Reach the starting point** — The address and starting instructions appear on the trail page. Once there, open the trail on your phone.
4. **Move from stage to stage** — Depending on the adventure, stages unlock on location or remain available in a roadbook. Follow the instructions on screen.
5. **Solve the challenges** — Quizzes, riddles, estimates, photos and mini-games call on observation, logic and teamwork. Hints can help you move forward.
6. **Discover your result** — At the end, see your score, badges, challenge summary and, when included in the format, the team leaderboard.

## Before you set off

- **A charged phone** — The game runs in the browser of the phone used by your team.
- **A mobile connection** — It loads stages, sends answers and keeps track of your progress.
- **Location access if needed** — Some trails use it to confirm your arrival at each stage.
- **Suitable clothing** — Check the duration, distance and transport mode before setting off.
