How to play Mirror Axis
Two 3D shapes appear side by side. Decide: MATCH (a rotated copy) or MIRROR (a flipped twin)?
Press ← for Match, → for Mirror — or tap the answer on touch devices. Keep your accuracy up as the shapes get trickier.
What it trains: 3D mental rotation
Mirror Axis poses the classic spatial-reasoning judgment used in mental-rotation research: two polycubes sit side by side, and only mentally rotating one tells you whether it's a turned copy of the other or its mirrored twin.
Mirror pairs can't be distinguished by any single feature — you have to rotate the whole shape in your head, which is precisely the skill the game builds run after run.
Mental rotation: the trainable spatial skill →Scoring & progression
Runs are short and scored — your best run sets your personal record. Strong runs feed your belt progression in the spatial discipline — from white belt toward black — and your place on the global leaderboard.
