- 🎓 Gate content behind a question — students unlock the next step by getting it right.
- 📱 Works on any phone, no install, no accounts for students.
- 🧩 Chain locks into a revision trail or a themed escape game.
A lock turns a plain question into a tiny game: get it right and something opens. That small dopamine hit is why gamified revision sticks.
Three ways to use locks in class
1. Self-checking exercises
Hide the worked solution behind a numeric lock whose code is the answer. Students only see the solution once they've solved it themselves.
2. Reading checks
Put a password lock at the end of a chapter; the password is a detail only careful readers caught.
3. A revision escape game
Chain five locks, one per topic, into a trail — exactly the pattern in how to build a digital escape game.
| Subject | Lock idea |
|---|---|
| Maths | Numeric — the answer to a problem |
| Languages | Password — a vocabulary word |
| Geography | Virtual GPS — find the capital on the map |
| Music | Musical — replay the scale |
Map a lock mechanic to each subject.
« When the answer unlocks the reward, checking your work stops being a chore. »
