Difficult Killer Sudoku book

Perhaps you’ve already noticed the cover of my new Killer Sudoku book. In case you haven’t, here is a proper presentation of this new and fiendish sudoku book.

So… many of you have asked for a book with only the most difficult of my Killer Sudokus. In “Revenge of Killer Sudoku 6” I dropped the easy puzzles and focused on THINKER and BRAIN levels of difficulty. Well, this time, I’m raising the bar at least two notches up. There are no more COOL and THINKERs! Instead, there are now just BRAIN, IQ and INSANE puzzles!

Yes, that’s right. INSANE. You asked for it. Here they are. Just to make things clear, what you get in this book is:

  • 40 BRAIN (5 diagonal)
  • 50 IQ!
  • 10 ZERO (including 8 ZERO INSANE)
  • 11 INSANE!

It doesn’t get any better than this. The summer will be HOT with these puzzles! Try them!

        Stravo,
        —-very good news! :o) And I’m still waiting for “my” second Flower/Outside too!!! Oh please… it’s a long time between May and October! P.e. for Summer-vacation!;o)

        And a warning!
        Hope that this will not happen to your new book too.
        There was a very bad “joke” on Amazon in the german entrances a short time ago. A woman bought an “ultrahardcore-sudoku” and could solve 4 puzzles only!!! The result: less stars and a very negative comment. First moment – really funny, because…. ;o), but in the end very bitter for the author!!!
