Three rods arranged side by side and rings that slide onto the rods make up the puzzle known as the Hanoi Tower (6 Layers). The objective is to move the rings to the entire opposing rod by according to the following rules: The rings begin on a single rod, with the biggest at the bottom getting smaller as you travel up. Besides-

1. You can only move one disk at a time

2. To make a move, remove the top disk from a stack and place it atop another stack or on an empty rod

3. No disk may be positioned over another disk that is smaller than it

With six rings, this version can be done in 63 steps. Why not give it a shot!
