Six Stax: free puzzle game app for iphone ipad

Six Stax is a game that is similar to Tower of Hanoi.  The object is to move the discs, one at a time, so that only a smaller disc can go on a larger disc of the same color and get all the towers organized properly.

We've seen this exact same puzzle app from another developer. Or maybe it's the same developer just using a different name. 

Besides solving the puzzles, can you solve them using fewer moves than other people?
