Rubik's Cube

Celebrating the 40th anniversary of the invention of the spatial geometry toy by Hungarian Ernő Rubik, this Doodle presents a digital version of the toy. The Rubik's Cube puzzle presents a cube whose six faces are each divided vertically three times and horizontally three times, making six groups of nine squares (or 54 squares overall). Each face starts in a unified colour but within a few twists along its axes, the coloured squares end up jumbled all around the cube's surfaces. The goal of this Doodle, as with the real-life toy, is to twist and turn its moving parts so as to reunite all the squares of each colour on one face of the cube each.
