(First one I made that I liked enough to keep, very easy)

(This one has a stupid long chain in it if you want a hint)

(This one has one time where you do a stupidly verbose solving technique.)

(My highest ranking puzzle according to another person's solver on "sudoku wiki")

(This one uses a rather silly technique that gets used rather early on in the sudoku wiki solver so odds are that years later you'll still be able to find out why this puzzle is silly)

(This one changes in rating by quite a bit, so I thought that this one might be worth posting too. Has quite a few chains in it last I checked, with a lot of other fancy BS you have to do to solve it naturally.)

(Here are some sudoku... I only post them since my code wrote them and some of them are silly difficult. If for some reason the numbers I chose offend you, you can exchange the numbers equally and entirely between each number (1s with 2s, etc.), and I let javascript's Math.random() function write everything. Simply copy into a grid going from left to right and going down row by row until the grid is filled up. I use a solver that I didn't write to check them though so these puzzles could actually be a lot easier than I say if you only half complete certain techniques. I don't actually do sudoku, I was just looking for a neat programming problem to solve at my level lol. Btw, I didn't just brute force a crapton of puzzles and spam the sudoku wiki, my generator can be told to look for patterns that I spent WAY too much time trying to perfect, but at least I could become a sudoku author if I needed to with how much code I wrote lol.)
