Rubik's Cube is a puzzle cube, and the world's biggest selling toy of all time with over 300,000,000 (300 million) sold. It was invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. In a classic Rubik's Cube, each of the six faces is covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. In currently sold models, white is opposite yellow, blue is opposite green, orange is opposite red, and some might replace blue with black or purple.
Types Of Cubes[change | change source]
Cuboids are cubes with uneven sides. Some options are the 3x2x2 or 3x5 or 4x3. Some cuboids can shapeshift or jumble. That means the cube goes out of its original shape. To solve a shapeshifting cube it must return to the original shape before it is considered solved.
Gear cubes include gears which cause both sides of a cube to turn.
Other versions include the Megaminx, Pyraminx, Rubik's clock, Mirror Cube, and Square 1.
