Tower of Hanoi puzzle is to move the entire stack to the second or third rod, obeying the following simple rules:
1. Only one disk may 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 or an empty rod.
3. No disk may be placed on top of a disk that is smaller than it.
4. Each move is considerable. Don't waste the move otherwise you lose the stars.
