What this game builds
Addition with a purpose. The number in a cage is not a drill but a clue — your child adds in order to find something out.
When your child gets stuck
Find a cage with a single cell — its number is the answer straight away. The rest unravels from there.
Ask afterwards
Was any number impossible for that cage? How did you work that out without trying them all?
