HOW

How a lockdown runs

For your team

  1. Open the terminal on one device. Pick your level, then tap the set letter printed on the front of your pack.
  2. Crack the door on paper. Every door has a matching page in your pack. Work it out and build its code.
  3. Type the code into the terminal. The door opens and gives you a key digit. Write it down.
  4. Enter the master code. Your key digits, put together, open the exit.

Choose your level

  • SafeGentler puzzles. A hint is always one tap away.5 doors
  • StandardThe full challenge. Hints appear after wrong tries.6 doors
  • MeltdownBrutal. Harder doors, and the master code runs backwards.7 doors

Teachers: print packs at 100% scale so the chromatograms measure correctly. Sets A and B carry different numbers, so seat neighbours on different sets. Answer keys and practical code slips are kept off this site.
