Enjoy this ancient puzzle - Tower of Hanoi - where a single player tries to move the full stack of rings from the first peg to the last peg in the minimum number of moves (15 for a set of 4 rings). There are only 3 rules: (1) Only 1 ring may be moved at a time; (2) A ring may be placed on any peg going forward or backward; (3) Larger rings may not be stacked onto smaller rings
