MOUNTAIN VIEW, Calif., May 19 (UPI) -- Google is celebrating the 40th anniversary of the Rubik's Cube by changing the logo on its homage into a playable version of the puzzle.
On reaching Google's home page, users will see the red, blue, yellow and green Doodle of Google's logo on the Rubik's Cube. Users can also click on the Rubik's Cube, which then spins and groans into a large interactive, online version of the game. Players can click to rotate and change the different sides of the cube, and Google will count the number of moves users take to complete the puzzle.
