Knight's Tour Puzzle by Carlos Magan FREE

Knight's Tour Puzzle comes from Carlos Magan.  The object is to place your knight on the board and move to all the squares exactly once.  Carlos has done a great job of introducing interesting shapes.
A true story: 30 years ago I was sitting in a pointless grad school class. The fellow next to me introduced this puzzle to me. The 5x5 grid.  Loved it.  The class seats were arranged in an open rectangle.  I always waited for the professor to sit first. Then I would sit on the same side, as far away as possible.  The class was stupid and pointless! But required. (Like a lot of education courses unfortunately)  I attended every class for 14 weeks. And did these Knight's Tour puzzles.  I solved all the grids from 5x5 to 15x15.  And proved that all nxn where n>4 is possible.

I wrote 2 papers and got a B+.

There's more to the story of how bad that professor was. You'll have to ask me in person for the rest. But don't we all have stories of boring/meaningless classes?
