I hadn't planned to try any more of these without pencil marks, but this one was already printed out and handy, and it looked pretty straight-forward, so I gave it a shot. Evidently I messed up something, because after making a good deal of progress, I came to a point where I was sure it had more than one solution. I ran it through both SudokuSolver and JSudoku, both of which assured me it had a unique solution. I tried again with pencil marks, and solved it in fairly short order.

On Børge's scale, I would rate this one at Apprentice level, Tough.
