In 1883, French mathematician Édouard Lucas invented the Tower of Hanoi, a puzzle that was the Rubik’s Cube of its day. It is still quite popular today and can be purchased in plastic and wood versions from many sources. It consists of three pegs and a number of disks of different sizes, which can slide onto any peg. The puzzle starts with the disks in a stack in ascending order of size on one peg, the smallest at the top, thus making a conical shape.
It was originally marketed with a very elaborate (and completely fictional) story about a tower of 64 disks sitting in a temple in Hanoi, where monks play the game day and night.
