Revenge of Killer Sudoku: 150 puzzles
About a year after my first Killer Sudoku book, I am ready to present you with a completely new book with my Killer Sudoku puzzles: Revenge of Killer Sudoku: 150 puzzles has been released!

US $5.99 or £3.30 or €4.82 (PDF e-book)
(payable by PayPal or credit card)
You will only find puzzles (and solutions) in this book. No talk. But what kind of puzzles!
The book contains:
- 100 Killer Sudoku puzzles
- 10 Killer X puzzles
- 10 Killer Sudoku with diagonal cages
- 30 Zero Killer Sudoku puzzles
Puzzles in this book are aimed towards advanced (and expert) solvers:
- 10 Easy
- 10 Cool
- 30 Thinker
- 30 Brain
- 40 IQ (some of which are actually INSANE)
+ those 30 Zero Killers which are “Out of category”, but lets say they are “IQ” level
I know that some visitors were willing to participate and supply their puzzles for this book. I was interested in that too, but after I asked for some advice on this, it turned out that it would require too much paperwork (release of rights etc). Oh well, maybe some day.
I hope you will enjoy solving these puzzles during the coming holidays.

I wonder if there’s a way to request an autographed copy when ordering?

:) No Amy, I didn’t envisage that someone would want a signed copy… I don’t even have any books in stock - these are print-on-demand books, unfortunately.

Well, why not send a signed photo to everyone who wants one?
(not for me, thanks!)
