I built this puzzle trying to learn how to create set equivalence theory (SET) puzzles. Sadly, although this puzzle is unique, it is beyond my own solving skill. For those of you with better advanced sudoku skills, I hope you enjoy this test puzzle. Any feedback would be sincerely appreciated (and much needed)!
