What this game trains and how it helps
Mental Rotation is a short spatial game: a target shape appears on the cabinet screen, then the deck shows turned copies. Your job is to pick the one that is the same shape rotated, not a mirror.
A trial is correct only when you choose the unflipped match. The mirror can sit at the same angle, so a quick glance is not enough — you have to turn the object in your mind and reject the flipped copy.
Early levels show two choices and quarter-turns. Higher levels add more foils and finer turns. Short sessions are enough. Two to five minutes is a comfortable dose. The game is a calm practice for anyone who wants to hold a shape and turn it — students, adults, and curious players — not a medical test and not a promise of special results. Play for that little turn in the mind, then come back another day.
How to Play
- A target shape appears on the cabinet screen.
- The deck shows rotated copies. One is the same shape turned. The others are mirrors.
- Tap the rotated match. A flipped copy is never correct.
- Higher levels add more choices and finer turns.
Goal
Pick the shape that is a rotation of the target. A trial is correct only when the chosen variant is the same shape turned, not flipped.
