Dear Diary, I continue to wonder if it’s just me, or if Irregular Sudoku puzzles are difficult for others as well. Also, I’ve worn my crayons down to nubs, and I don’t know how to solve irregular puzzles without coloring…
Rules:
Normal Irregular Sudoku rules apply. (There are nine regions of nine cells each, but they are not 3x3 squares.)
Anti-King: Diagonally-adjacent cells do not contain the same digit.
Estimated difficulty: 3 out of 5
