How to play Symmetry Snap

A shape appears on one side of the board’s center line. Tap the cells that complete its perfect mirror image on the other side — every lit cell reflects straight across the axis, same row, mirrored column. Finish the reflection to score (faster and longer streaks pay more) and the next, bigger shape arrives with a little less time. One wrong cell ends the run. Mental mirroring is a core spatial-reasoning skill — the one architects and surgeons test on — and this is its gym. Free at Skorven, in the browser.

Tips & strategy

• Work row by row: each lit cell’s mirror is in the same row, counted the same distance from the center line.
• Trace the shape’s outline first, then fill — outlines mirror more reliably than scattered cells.
• On big shapes, do the cells touching the axis first; they’re their own anchors.
