The Guardians: the Game
Raccoons love biscuits 🍪. You are the building's engineer. Place the sensors so that the chain notices them in time — then the control panel gives a signal, the centre sends the patrol and the raccoons go home. Nobody gets hurt, and the biscuits stay for the party.
How to winOnly the whole chain stops a guest: a sensor notices → the control panel thinks → a signal (siren and message) → the centre checks → the patrol comes. If one link is missing, the guest gets through. Stars are for spending wisely — no stars for hurrying.
For the teacher: a guide — how to play in class.
