Troyis: free chess puzzle app game for iphone, ipad

Troyis is a Knight's Tour type of puzzle.  The object is to land on all the white squares as quickly as possible.  Other squares cannot be landed on.

Check out the image of the horse with an attitude.

Many years ago, while taking a boring course, I did the knight's tour for grids 5x5, 6x6, 7x7......14x4.

Troyis is a free puzzle app.
