There are
NO EASY PUZZLES in this new volume of the Revenge of Killer Sudoku book series. Again, I read your reviews and figured out that you wanted more challenging Killer puzzles, so this is what I came up with. 🙂 Not only that the puzzles labeled EASY have been eliminated, but also, I think that the IQ puzzles are more fiendish than before.

So…
- 100 Killer Sudoku puzzles
- 10 Killer Sudoku with diagonal cages
- 10 NON-CONSecutive Killer Sudoku X
- and 30 ZERO Killer Sudoku (blank cages)
