Five Diagonals
(Published on 29. July 2025, 21:50 by SumDumThum)
Rules:
Normal sudoku rules apply.
Cells that are diagonally adjacent may not contain the same digit.
Cells that are adjacent orthogonally or along a negative diagonal may not differ by a multiple of three, e.g. the cells orthogonally adjacent to a 5 cannot contain 2 or 8, nor can those adjacent to the southeast or northwest.
Cells along an arrow sum to the number by the arrow.

Had no idea where to start, then your previous puzzle showed me the trick. Clean puzzle, nice work!

Very satisfying. Had to go back to the first puzzle to understand the trick. Again I think a ruleset using "modular" would help intermediate solvers like myself understand more easily.

Nice and easy, if you spot the trick. Actually you can solve it by using just three of the diagonal clues.

this cannot possibly be level 2.
there is literally NOTHING to "bite on"
