Easy Killer Sudoku book

By djape | Published: May 15, 2013

I’ve published many Killer Sudoku books and I kinda have a reputation for creating only difficult killer sudokus.

Well, I decided to change that and therefore I prepared and published a book with only really EASY Killer Sudoku puzzles. If you’ve been scared to try the Addoku or Sumdoku (as these puzzles are also known), this book should take away that fear. The instructions are clear and nicely introduce you to Killer Sudoku solving techniques.

Finally, this book is also suitable for children who can add and subtract. That’s all they need to know to solve these puzzles. So, it’s a nice gift for your kid to keep themselves busy over the coming summer. :)

So, what are you waiting for?
Try it, it’s worth it! The book is just $7.95 or £4.99!!!
(NOW DISCOUNTED TO $7.16!!!)

By the way, isn’t that the prettiest book cover I ever created? :)

Oh… for those of you who are already well versed at solving Killer Sudoku, I have some good news. I also published a different book only with the most difficult Killer Sudoku, yes, including some INSANE Killers! More about that in a few days… you can already find a link on the Killer Sudoku page.

Big Nonograms Book

By djape | Published: May 7, 2013

I’ve published several griddlers books, which contained mostly medium sized grids, between 20×20 and 30×30, with only a few larger ones.

Well… this time I present you a book of somewhat larger picross puzzles! Almost all puzzles in this book are between 30×30 and 40×40 in size.

And one more interesting fact about this book: almost all images were drawn by my Mom! :) And I think the grids turn into beautiful images. Thank you so much, Mama! :)

IMPORTANT: The book is currently discounted by 10% Amazon US! Not sure how long it will last, it is not under my control. So better get it now. :)

CalcuDoku books

By djape | Published: February 27, 2013

Here is a list of all of my books with CalcuDoku puzzles, which are also known as MathDoku, OpDoku and many other names.

So far, there are 3 volumes of classic Calcudokus (I tend to make them more difficult than other authors, so be careful!), one with Calcudoku for Kids (easy stuff, but not trivial and very good for learning!) and one very special book with overlapping Calcudoku puzzles – Samurai CalcuDoku.

Pirates’ Games

By djape | Published: January 29, 2013

This is not a puzzle related post. :) It’s a brain teaser (I used to post brain teasers years ago). I’ve been studying game theory lately and wanted to share one “classic” problem of this discipline with you. See if you can solve it by yourself. Post your solution as comments below this post.

So… here we go…

Pirate Games

Five pirates have obtained 100 gold coins and have to divide up the loot. The pirates are all extremely intelligent, treacherous and selfish (especially the captain) each wanting to maximize the number of coins that he gets.

It is always the highest ranked pirate who proposes a distribution of the loot. All pirates vote on the proposal, and if half the crew or more go “Aye”, the loot is divided as proposed.

Nonograms for Kids game on Kindle

By djape | Published: January 25, 2013

Hello folks, this is my first post in 2013. :) So, Happy New Year! :) Hope you had nice holidays.

So we start the year with a gift for children. :) Quite appropriate I would say. It’s a Griddlers Nonograms Hanjie Picross game for Kindle, but this time, the puzzles are of suitable level to be solved by children. Starting clues (black and white cells) are given so that your kid would know where to begin.

It’s a nice change. Remember, I’ve already released two games for kids on Kindle, Sudoku for Kids for Kindle and KenKen for Kids on Kindle.

Griddlers for Kids … JUST $0.99!!!
