On the original classic cube, each of the six sides is covered with nine stickers, each of which is one of six solid colors: white, red, blue, orange, green and yellow. The current version of the cube has been updated to color plastic panels to prevent peeling and fading. In the models currently on sale, white is relative to yellow, blue is relative to green, orange is relative to red, and red, white and blue are arranged in clockwise order. On earlier cubes, the location of colors varied from cube to cube. The internal pivot mechanism allows each face to rotate independently, mixing the colors together. In order to solve the problem, each face must be returned to only one color. Similar puzzles have emerged, including various numbers of sides, sizes and stickers, not all of which are Rubik.
