Fold

Stare at a flat cross of squares, fold it into a cube in your mind, and call which faces meet.

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.

Game modes

• Daily: a seeded puzzle set everyone shares that day.
• 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.

• Skills: spatial visualisation, symmetry, mental rotation, geometric reasoning
• Best for: roughly grades 4–8 (ages 9–14)
• For parents & teachers: a focused workout for the mind's-eye skills geometry leans on.
