ZERO Killer Sudoku, Killer Samurai 3 and Jigsaw Sudoku 2 on Amazon
Here is a Christmas gift for you! Just in time for the holiday season, three new books have been published on Amazon:
That’s right, I listened to your requests and have prepared a book full of only ZERO Killers and nothing else!
These books will NOT be published through LuLu!
This should take you through the holiday season.

Bit sad they won’t be available through Lulu. The shipping is prohibitive for those of us not in the US. I bought 5 books just last month to tide me over the festive season and am a very happy camper!

Many thanks Djape

They will help “kill” my 24 hour flight to Australia in February

Yeah, DJ…Why not publish on Lulu?

I addict to Zero Killer Sudoku and wait every Sunday to the new Killer.
Publish through Lulu is the most convenient and faster way for me to purchase this books.

Hi Djape
Today’s zero has more than one solution.
The 12 box in the bottom center square can be 8,4 or 7,5 – both work
Still think these are great puzzles,can’t wait for my book to arrive next month !!

I found a unique solution. The 12 box has 7,5 in my solution. So your other solution with 8,4 must be wrong. There must be two same digits in one of the rows, columns or 3×3 squares. Double (or triple) check it and you will see I am right!

It’s a shame, they can’t be purchased as downloadable files. I have been waiting for the Zero Killer book, as these are my favourite ones. Second favourite is Jigsaws, so would have been a nice present for me!
But looks like I won’t be ordering them, as they’re from the US.
Please, djape, change your mind and make them available for download!

Zero Killers are my favorites.
Until now I ordered almost all your books from Lulu (as download files).
Can you please change your mind and make at list the Zero Killer book available for download!

Hi nikoli_freak
Djape’s solution had 8,4 in the 12 box,
8.4 and 7.5 both work in the 12 box
these are great puzzles ,but this puzzle unfortunately has more than one answer.
I am sure Djape will agree with me

Dave T,
please provide the full solution that you have found. Partial solutions are not enough.
Then we’ll have a look and see if you went wrong.
Cheers!

Last time I checked djape’s solution, the 12 box (Column 6, Rows 7 &
was 5,7. You must have had plenty of drinks (or other substances) if you somehow found a “12 box” with 8,4 in there. 
I am 100% certain djape (and many other visitors) have worked out the correct unique solution like me, and you are the only one thinking that puzzle has more than one answers.
Proof: you are the only one here making that complain. If there are indeed more than one answers, how come no one else made any complaint?
But like djape said, just post your full solution with 8,4 in that 12 box, so we all can see where you went wrong.

Dave, you must have guessed at some stage. The problem with the first of your solutions is that it doesn’t add up. The center 32/5 cage in your solutions adds up to 29, not to 32 as it should.
I didn’t check the second solution, but I suspect it’s the same kind of problem.
Good try though!

Once it is on Lulu I will add it to my collection of DJAPE acquisitions – Books are no good as once I go wrong I want to start again – hence the value of a pdf.
