Cubefold

Mentally fold the marked net into a cube, then choose which of four candidate cubes it actually becomes — one is a sneaky mirror image.

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

What you'll learn

Cubefold is built around net-folding and mental-rotation tests, sharpening 3D spatial visualization.

• Skills: mental rotation, nets and 3D shapes, spatial visualization
• Best for: roughly grades 5–11 (ages 10–16)
• For parents & teachers: folding flat nets into cubes in your mind.
