Tower of Hanoi

TOWER OF HANOI

A puzzle where by moving one ring (or disk) at a time from peg to peg and having no ring placed on a larger ring, the entire stack of rings is moved to a different peg.

Manual and Auto modes. In auto mode, the current state is used to determine what move to execute next.

Three to eight ring range.

Changing manual/auto mode or number of rings resets the puzzle.

Still needs completion detection.

So, it takes 2^(n)-1 moves to do it most efficiently. Cool.

A new version of this scenario was uploaded on Sun Dec 22 01:29:37 UTC 2013 Added completion code. Big plus: simplified auto movement code!
