What habits help with spatial puzzles?

Two habits help when a picture has to change in your head. First, track one corner or one mark at a time instead of the whole shape. Second, say each move out loud: fold left, roll forward, turn a quarter clockwise. Naming the move keeps you from mixing up a turn with a flip.

Easy picture puzzles

Good warm-ups for your eyes. Look at the whole picture before you answer.

Medium picture puzzles

Hidden letters, layers, colour filters, shadows and folding. Take your time with the cube net.

Hard picture puzzles

Reflections, rolls, folds, a letter grille and gears. Track a single mark through every step.

Where do spatial puzzles come from?

Using six colours, one per face, a cube can be coloured in 30 different ways, and a 2018 paper showed that each of the 30 can be built at double size from 8 of the others with matching inside faces ^[1]. Martin Gardner asked whether squares of side 1 to 24 could be packed into a 70 by 70 square, which has exactly the same area, and by 2018 it was known that no packing beats one that leaves out only the 7 by 7 square ^[2].
