This page lists useful techniques for solving the Tower of Hanoi.
The puzzle can be solved by a single, simple algorithm:
- Move the smallest disc from the top of its pile to another one
- Move the only other moveable disc to the only place it can go
- Repeat the above two steps until the puzzle is solved
Note that the smallest disc must always move the same way, i.e. if it is moved from the left-hand pole to the middle one on the first move, then it must move to the right-hand one the following time, then back to the left-hand one, and so on.
