Stare at a flat cross of squares, fold it into a cube in your mind, and call which faces meet.
Was this fun?
How to play
Each round shows an unfolded six-square net with a symbol painted on every face. Picture the net folding up into a cube and answer the question posed about the result. You get ten rounds; faster correct answers earn more.
Opposite questions: pick which symbol ends up on the face directly across from the highlighted one.
Adjacency questions: decide whether two highlighted faces touch (adjacent) or sit opposite.
Validity questions: judge whether the net even folds into a complete cube without two squares overlapping.
Difficulty climbs as the rounds progress; a small reference cube is drawn to help you orient.

Practice: an endless run of random nets.
Tips & strategy
Fix one square as the base, then walk the connected squares up the sides, opposite faces are the two you never fold next to each other.
On a standard cross net, faces two steps apart along the arms are opposite; neighbours along a straight run are adjacent.
Answer quickly once you are sure, speed adds to your score.
What you'll learn
Fold turns mental paper-folding into a quick-fire quiz, training the spatial visualisation that underpins geometry and many reasoning tests.
For parents & teachers: a focused workout for the mind's-eye skills geometry leans on.
Origins
Picturing a net of six marked squares folding into a cube, then answering about the result, is spatial visualisation without a model to handle.
Asking a question about the folded cube rather than asking you to identify it is the original twist.
Questions about opposite faces are the useful ones. Two squares are opposite on the cube exactly when they are separated by one square in the net, which is a rule you can apply without folding anything — and discovering it is worth more than getting the answers right.
