Fold Out
A flat net sits on the card · pick the 3D solid it folds up into. Cube, pyramid or prism, decided by pure visual-spatial reasoning
About Fold Out
Fold Out is a compact PlayMemorize mini-game about spatial visualisation. A flattened 2D net sits on the card · picture it folding up and choose the 3D solid it becomes.
How a round works. You read the net, mentally wrap it into a cube, pyramid, or prism, and tap the matching solid. Feedback is immediate, and a new seeded round keeps the puzzle fresh without sending any state away from your browser.
Still in beta. Fold Out was broken out of the Spatial Reasoning hub into its own game · it is still being tuned, so you will find it in the Beta section of the library.
Age-aware practice. Library links can carry an age band into the game so the opening difficulty fits the player who launched it.
Part of PlayMemorize, a passion project from Christoffer De Geer. It runs in the browser and is designed for short, honest practice rounds.
FAQ
-
What does Fold Out train?
Fold Out trains spatial visualisation · the mental skill of folding a flat net into the solid it represents · through short rounds with immediate feedback. -
Which shapes appear?
Each round asks you to fold a net into a cube, a square pyramid, a triangular prism, or a rectangular prism, and to tell them apart from the net alone. -
Why is Fold Out in beta?
It was just split out of the Spatial Reasoning hub into a standalone game, so it lives in the Beta section while its difficulty and visuals are finished. -
Why is Fold Out excluded from worksheets for now?
Net folding is a 3D mental-rotation task; a static paper sheet would have to picture the fold for the student, removing the very step the game trains.
