The logic in this is as smooth (and creamy) as room-temperature butter! :)

Very fun and satisfying solve with some amazing and clever logic that at times felt too good to be true

Very tough for me, but awesome setting. Might be the best quad sudoku I have solved.

I particularly love quad puzzles, so it's amazing to find a pure quad with such a smooth, fun solve. Thank you PotatoHead21!
