Box Clever is a book of trick puzzles set in a toy theatre made from a cardboard box. Every level asks a simple question: save the melting snowman, turn on the light, get the ball in the hole. The obvious answer doesn't work.
Everything on the stage is a painted cardboard cut-out, and that's the one rule: if it's a cut-out, you can try moving it. Drag the sun behind the hills, lift the word "on" out of the question and drop it on the lamp, or tip the whole phone to pour the tea.
There are 200 hand-made puzzles. The first are gentle enough for children to solve on their own; from level 50 they get harder every ten levels, until the grown-ups are stuck too. Wrong tries get a kind nudge, never a penalty, and each solved level explains its trick in one sentence.
