Mentally fold the marked net into a cube, then choose which of four candidate cubes it actually becomes, one is a sneaky mirror image.
Was this fun?
How to play
A flat net of six symbol-marked squares sits on the left. Visualise folding it into a cube, then click the matching cube from the four candidates on the right. Exactly one is the true fold; one is an adversarial mirror twin that differs only in handedness, and the rest are face swaps.
Each face carries a distinct glyph so orientation and chirality read clearly
Drag any candidate cube to spin it in 3D and inspect every face before deciding
Solve quickly and build a streak for bonus points
Controls
Desktop: drag a cube with the mouse to rotate it; click a cube to lock in your answer.
Phone & tablet: drag to rotate, tap to select, fully touch friendly.
Game modes
Daily: the same date-seeded round for everyone
Practice: fresh random rounds at Easy, Medium or Hard
Tips & strategy
Pick one face you are sure of and track which glyphs sit adjacent to it after folding
The mirror twin is the trap, compare the rotation direction of asymmetric glyphs like the arrow and the L-shape
Rotate the cubes rather than guessing; the chirality only reveals itself from the right angle
