LetCube: Cube Guide for Kids

Pick up a real cube and learn to solve it with friendly 3D guidance. Cube Academy turns practice into stars and levels that grow with every session.

LetCube turns cube solving into a visual learning game that children can understand and follow.

A matching 3D cube shows every change. Instead of memorizing formulas first, kids learn by turning, observing, checking, and correcting. A wrong turn is not failure—LetCube keeps collecting clues and always offers another useful step.

QUICK SCAN OR MANUAL INPUT Photograph the six faces in numbered order and LetCube recognizes the whole cube. Every face can be reviewed, retaken, or fixed with a tap. The complete 3x3x6 color editor is always available when the camera is not.

STEP-BY-STEP 3D GUIDANCE Every step is a real, gentle turn of the 3D cube with friendly arrows on the moving layer — no cryptic notation to decode. Play or pause, step back, step forward, at a pace you choose. Reduce Motion replaces animated effects with clear static guidance.

CUBE ACADEMY Start with small lessons, then solve scrambled cubes, then play freely. Every finished round earns stars and points—full stars for solving alone, and stars are always earned even with hints. Levels grow with practice, so children can see their own progress.

KID-FRIENDLY THEMES Choose classic colors, animals, or fruits. Themes change only the display—not cube recognition or solving. Narration, sound effects, and guide speed are adjustable.
