I mean hard, I have the brown belt sudoku book, and it’s way too easy, as well as the Mensa sudoku. I’ve played the brain age sudoku on Nintendo DS and solved all of them, I like the hard ones on there, that’s what I’m looking for.

    There’s a couple advanced books that I’d recommend,

    “Sudoku Genius: 144 of the Most Fiendish Puzzles Ever Devised”

    “New York Post Fiendish Sudoku: The Official Utterly Addictive Number-Placing Puzzle”
