Prices on some of my books – SLASHED!

djape — Sat, 13 Mar 2010 10:08:03 +0000

Some of my books are being heavily discounted at the moment. Before I introduce them to you once more, let me kindly ask you again to review my books on Amazon if you buy them. If you have already bought them, you can still do that. It means A LOT to me!

My first Kakuro book: This book is undeservedly neglected. I know my Kakuros are of top quality. Some of you know that too. Those that don’t know that yet should look at the Kakuro category and try some of my puzzles there. Further, this book is the only book (as far as I know) that contains Kakuro variants: odd/even, (non)consecutive, greater/less than. And on top of that all, it is now priced only $6.95 on Amazon!!!
Djape does Sudoku: 300 puzzles for ADVANCED solvers: This is not a book with your ordinary puzzles that you can find in your local newspaper. This puzzles are rather difficult. On top of it, it contains 60 puzzles that require you to apply either the X-Wing or the Swordfish techniques. It is now priced only $7.95 on Amazon!
Sudoku Straights: Where Poker Meets Sudoku: A one of a kind book! Books with such puzzles have not been published elsewhere. Try some of them from the Sudoku Straights category. The book is dirt cheap: only $6.95!!! on Amazon!

From what I know, there will be no further reductions in prices. And the prices on these books might go back up! So now is the best time to get them.

Outside Sudoku Straights (difficult!)

djape — Fri, 12 Mar 2010 11:55:48 +0000

Here is a new variant of Outside Sudoku puzzles: Sudoku Straights.
The rules of Outside Sudoku are explained here.
The rules of Sudoku Straights are explained here.

Now, all you need to do is combine them and apply them both. It’s a rather difficult puzzle (or so I think).
What do you think?

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:

Sudoku Straights

djape — Wed, 21 Jan 2009 16:45:03 +0000

It’s only Wednesday, but I decided to present you with another Sudoku Straights puzzle. Remember that they are shown every Friday on the Daily Sudoku page.

The rules:
1. Use numbers 1-9. Numbers cannot be repeated in rows/columns.
2. There are no nonets (3×3 boxes) like in other Sudoku puzzles.
3. Black cells do not contain numbers. Therefore, not all numbers 1-9 will appear in all rows/columns. (Be careful when applying hidden singles!)
4. And the main rule: numbers in one row/column that are between two black cells (or between a black cell and the border) must constitute a sequence, or if you prefer poker (texas hold’em or whatever) terminology, they must constitute a straight. Now, do not confuse this with consecutive sudoku! The numbers can be in any order, adjacent numbers need not be consecutive! Just like in poker.
