Super Sudoku Quad Samurai Book

A new volume with QUAD Samurai Sudoku Puzzles has been released.

I tried to keep the price of this volume lower than others. Therefore, in this volume, you get 80 classic Super Samurai Sudoku puzzles, plus a couple of surprises at the end.

World’s Hardest Killer Sudoku, vol 3

A new volume of World’s Hardest Killer Sudoku has just been published. Nothing’s changed from previous 2 volumes: 90 IQ Killer Sudokus and 10 INSANE Killer Sudoku puzzles in this book. Well, of course, all puzzles are NEW, not published before.

This book is certainly now for beginners. It is only for experienced Killer Sudoku solvers.

Are you up for this challenge?

Picross book with 255 ALL NEW puzzles

Here is the first book for 2021 season!

It’s a Nonograms book with 255 puzzles. What’s important is that all puzzles in this book are NEW, and not published elsewhere. And they will not be published elsewhere. I plan to release one volume with about 250 puzzles (give or take) every year.

A majority of puzzles are THINKER and BRAIN difficulty.
Furthermore, more than 50 puzzles are of the sizes 15×15, 15×25, 30×20 and 30×40 each. I think those are the best sizes for picross puzzles, where 30×40 is, obviously, the most challenging and best looking puzzle size of all, with most details.

I really do think that this is the best Griddlers books I’ve published so far. The images are absolutely beautiful. And the puzzles are not too easy and not too hard. Well, some of them are a bit hard. But most of them are just the right difficulty.

Hope you will like it!

Oh, Djape…

Back in the day, this website used to be alive and kicking. Now it’s barely alive and certainly not kicking anymore.

I tried to revive it, I even hired an agency to build a totally new website but, let me be frank, running a website never was my thing. I like programming and making puzzles, that’s all. And I will keep doing that in the form of the books I publish, which can be purchased from Amazon.

The content of this old website should all be there and you should be able to find the old puzzles and stuff. If something doesn’t work, please let me know.

If you, dear visitor, are interested in running my website and running newsletter campaigns on a PRO BONO basis until we see if we are a fit, please contact me at: djape at djape dot net.

I will occassionally update the website with information about new books and that’s more or less all.

Make sure to subscribe to my newsletter, that way you will be updated about new books.

Sorry… It was a lot of fun back in 2005 and until about 2009-2010.

But don’t worry… NEW BOOKS are coming VERY SOON!

Cheers <3

Transitioning to a new website

This is the old Djape.Net – The Home of Perfect Sudoku website.

The domain name has been changed. As of today, this website can be reached by using perfectsudoku.com domain name. And it will stay like that for… well, I don’t know for how long.

The old domain djape.net still points to this same website, but that’s about to change. Please bear with me until I’ve implemented everything. New djape.net website will be much more personal and not only about puzzles.

There will be a third website at djapedjape.com. This website will be used to find my new books, download free puzzles, free coloring pages and download The Washington Post Samurai Sudoku Solutions. There will also be e-books with puzzles for you to download and print, very cheap. Like I said, all this will take a long time to implement and put together.

If you have any questions, or if you find that something doesn’t work, please contact me at djapedjape@gmail.com, that’s my best email address at the moment.

I certainly hope to find strength and time to continue what I started in 2005. Your support means a lot. Really, it does.

Thank you and I’m really looking forward to hearing from you… about stuff that’s been broken on this website. 😀
