I saw this (Zombie Sudoku) in a bookstore today. Had to take a photograph and share with you all. Sorry it’s so blurry. I was crying a tear for my genre.
But really, I should have seen this coming when “hard” sudoku became superceded by “evil” sudoku in many puzzle books. While technically, “satanic sudoku” should have come next, it was only a matter of time before “zombie sudoku” took the place of that. But I think it would have been much more challenging to release “parasitic sudoku” or maybe “bacterial infection sudoku” instead. Or maybe just “leech sudoku”. Yeah, I like that one. Leeches. Ten of them in the row….
