The Tower of Hanoi is a mathematical game or puzzle.

The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules:

1.Only one disk can be moved at a time.

2.Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack.

3.No disk may be placed on top of a smaller disk.

With 3 disks, the puzzle can be solved in 7 moves. The minimal number of moves required to solve a Tower of Hanoi puzzle is 2n(2 raise to n) − 1, where n is the number of disks.
