Turn block shapes in your head, and build them floor by floor.
Turn 3-D shapes in your head and build them block by block.
Being able to turn a shape in your head goes along with doing well in maths and science, and it gets better with practice. Here you spot which block shape is the same one just turned (not flipped like a mirror), and build shapes one flat layer at a time until they match the goal.
Practice helps: a review of 217 studies found spatial skills improve with training and the gains last (Uttal et al., 2013, Psychological Bulletin).

-
Turnwick turns a shape through space: a new pose, the same shape. -
Twinn is the mirror twin that no turn can ever match, like your left hand and your right. -
Roundle keeps all 24 turns of one shape together, as one family. -
Layla builds one flat floor at a time, from the ground to the roof. -
Cubbin is one cube in exactly one spot. Every big build is made of Cubbins. -
Fitwell says “matches” only when every block lands exactly where it should.
