Inventions - Tower of Hanoi: the classic mathematical disk puzzle
Inventions · 0:33
The Tower of Hanoi is a mathematical game featuring three vertical rods and a stack of disks in decreasing sizes. The goal is to transfer the entire stack from one rod to another, moving only one disk at a time and never placing a larger disk onto a smaller one. Named after the capital of Vietnam, the puzzle requires a minimum of two to the power of n minus one moves to solve for n disks. For three disks, completion takes just seven steps.
