Rubiso: Cube Solver

Rubiso helps children (and grown-ups!) solve a classic 3×3 puzzle cube, step by step.

SHOW IT
Hold each side of the cube up to the camera, in any order. Rubiso takes the picture by itself when you keep still, and fills a colourful bubble for every side it has seen.

CHECK IT
See your cube laid out flat. If a colour was read wrong, tap the square and fix it.

SOLVE IT
Rubiso finds a short solution (usually about 20 moves) and shows every move with a friendly 3D cube:
• "Find the side with the red middle and point it at you."
• "Now turn it like the hands of a clock."
A voice reads every step aloud, so even children who can't read yet can follow along. The middles of the cube never move, so you can't hold it the wrong way.

CELEBRATE
Confetti and a fanfare when the cube is solved!
