- 👶 For kids — colours, pattern, direction (no reading required).
- 🌳 For outdoors — real GPS and compass.
- 🧠 For difficulty — ordered switches and grids scale up fast.
All 14 mechanics hide content behind a code — but the right one depends on your players and setting. Here's a fast way to choose.
By audience
Young children do best with colours, pattern and direction — visual, no spelling. Teens and adults enjoy musical, switches and grids, which reward observation.
By setting
| Setting | Best locks |
|---|---|
| Classroom | Numeric, password, musical |
| Indoor party | Colours, pattern, switches |
| Outdoor hunt | Compass, real GPS |
| Remote / online | Numeric, login, virtual GPS |
Match the mechanic to where players are.
By difficulty
Easiest to hardest, roughly: numeric → colours → pattern → direction → musical → switches → ordered switches → grids → geolocation. Mix easy and hard across a trail to keep momentum.
