A magic cube is an version of a magic square in which the rows, columns, pillars, and four space diagonals each sum to a single number known as the cube’s magic constant. Magic cubes are most commonly assumed to be “normal,” i.e., to have elements that are the consecutive integers 1, 2, …, . However, this requirement is dropped (as it must be) in the consideration of so-called multimagic cubes.
It seems like such a simple puzzle and yet the Rubik’s Cube mesmerized millions of people with its complexity. The Rubik’s Cube became one of the most popular toys of the twentieth century and an icon of the 1980s.
It seems simple enough. You would pick up the Rubik’s Cube and turn it a few times. The goal is to make each side a solid color, as it is when you first take it out of the box. After a couple of hours, you realized you were mesmerized by the puzzle and yet no closer to solving it. This exact situation happened to millions of people in 1980 as the Rubik’s Cube became an obsession around the world.
Rubik’s Cubes instantaneously became an international sensation. Everyone wanted one. It appealed to youngsters as well as adults. There was something obsessive about the little cube. A Rubik’s Cube had six sides, with each side a different color (traditionally blue, green, orange, red, white, and yellow). Each side of a traditional Rubik’s Cube consisted of nine squares, in a three by three grid pattern. Of the 54 squares on the cube, 48 of them could move (the centers on each side were stationary). Rubik’s Cubes were simple, elegant, and surprisingly difficult to solve.
