I don’t know what the punch line to this joke would be. Not a newspaper, not a penguin. Well, penguins are a bit odd, I guess. Could still be a penguin.
I mean, literally the answer is this puzzle, right? Except I color odd and even cells, undermining the whole “black and white” part.
Rules:
Normal Sudoku rules apply.
Digits in cells marked with an orange circle are odd. Digits in cells marked with a green square are even.
Cells separated by a white dot contain consecutive digits. In cells separated by a black dot, one digit is double the other. Not all possible dots are given.
Estimated difficulty: 1 out of 5
