It's basic VARIANT sudoku, (did I use ALL CAPS correctly?) Please continue with your ZERO published puzzles to find value in your life to act like an authority without a YouTube channel or other outlet to offer solves or critiques and analysis on actual authors' work. VitP appears to be a troll that did not solve this puzzle, according to the solve list. Felis did solve...also no published puzzles and solve time around the same time as this comment. I do appreciate color and fun in the community! keep it up!! I'll be enjoying watching the Super Bowl with other millionaires this Sunday with my real job and real life.
