What's this??

Four stars forward, and three stars back.

I am puzzling terribly over my three star soduko. I could just rip it up and pretend I had never seen such a thing... or then... I could puzzle along further... and wind up in a fine state of puzzlement. This isn't a regular three star puzzle, I feel it has disguised itself as a three star, when actually it should be the maximum five star.

I will give myself another hour, but after that... it's hitting the bin marked with a capital "R".
