Just now noticed this (because both puzzles are "out of my league" right now), but the images for #3 and #4 are the same (and the image for #4 doesn't match the code string).

(I'll bet you were just testing us to see how long it would take us to notice, weren't you? :cheesey: )

Sure, you are hereby the official winner. :queen: :applause:

Thanks for telling me about the error. For #4 I had made the correct screen shot, but posted the link for #3. This is now corrected.
Using JSudoku 1.5b1 I have also redone some of the techniques' lists needed for solving. By moving up XY-Wing, it is now the only advanced technique required for #2, #3 and #4.

I'm just starting to get the hang of XY-Wings (I think), so maybe I can make it up through #4. Thanks for the corrected image!
