Overlapping CalcuDoku (Square Wisdom, MathDoku) puzzle

djape — Wed, 12 May 2010 20:35:45 +0000

It’s been quite a while since I last posted a CalcuDoku puzzle. I’m going to fix that now and to make it up to you, it will be a somewhat special variant of Square Wisdom puzzles.

It’s an overlapping, 2 in 1 (Gattai-2), CalcuDoku puzzle, which is essentially in a TwoDoku layout.

Remember the rules: there are no 3×3 nonets (nor any other kind of nonets). You only need to make sure that each row and each column contain one occurrence of each digit. And finally, unlike Killer Sudoku puzzles, in CalcuDoku puzzles numbers can be repeated in each cage!

Of course, if you need assistance with cage combinations, you can use the CalcuDoku calculator.

In order to avoid any further confusion with KenKen(R) and KenDoku(TM) trademarks of Nextoy, LLC, I have changed the name of these puzzles to CalcuDoku.

This name is also used by other publishers but it is not trademarked.

3 new books: “The Way of Samurai volume 3″, “Picross, Hanjie, Griddlers, Nonograms: 130 puzzles” and “Square Wisdom: 200 CalcuDoku puzzles, volume 2″

djape — Wed, 11 Feb 2009 21:39:52 +0000

I’ve published 3 more books through CreateSpace: two new volumes of old books and one book that is new for Amazon. Here is what they are:

The Way of Samurai: 105 Samurai Sudoku puzzles, volume 3

Square Wisdom: 200 KenDoku puzzles, volume 2

Picross, Hanjie, Griddlers, Nonograms: 130 puzzles (please read below!)

Although first two books don’t need too much introduction, here is a brief description:

The Way of Samurai 3:

80 classic, 20 diagonal and 5 surprise Samurai Sudokus! While all puzzles are new, one of the surprise Samurais is extra special: no such puzzle has ever been published before – it’s a Samurai Sudoku Straights puzzle.

Square Wisdom: 200 CalcuDoku puzzles, vol. 2:

Everything is exactly the same as in volume 1, except of course that the puzzles are all new.

and finally…

Picross, Hanjie, Griddlers, Nonograms: 130 puzzles

This book is completely new for Amazon. However, I must tell you that a few of the puzzles in this book have already been printed in my LuLu book “Hanjie: 60 puzzles”. For various reason it had to be that way, primarily because of the way these puzzles are created.

These books are also available for download as e-books from LuLu:

“Hidoku: The Next Puzzle Craze” and “Square Wisdom – Calcudoku” books available on Amazon

djape — Sun, 16 Nov 2008 16:52:28 +0000

The two recently published books are now also available on Amazon:

Hidoku – The Next Puzzle Craze: 150 puzzles

Square Wisdom: 200 Calcudoku puzzles

Again, I would GREATLY appreciate if you rate and/or review my books that you purchase on Amazon, no matter if your review is positive or negative. It means a lot.
