Puzzles & brainteasers

A locked compartment wants to be opened. While building, you learn how bolts and number wheels interlock – and afterwards you get to watch everyone else puzzle over it.

Build the safe, set the code and give it locked. A clue on the card, a riddle on the table – and suddenly the whole family is puzzling along. Would they rather build it themselves? Then give the kit: Gifting a model when you don’t build yourself.
