DJ Ape .Net – The Home of Perfect Sudoku

I hope you all had a nice Christmas and that you are enduring the cold weather well. Well, those in the Northern hemisphere anyway.

Let me tell you about the changes that I plan for 2009:

There will be more Jigsaw Sudoku puzzles on the Daily Sudoku page. They will be accompanied by the Sudoku Straights puzzles, which is something new, but I think you should learn. There will be fewer (non)consecutive puzzles – it seems they’ve gone out of fashion.

The “Download” page with Perfect Sudoku v0.4 is gone. That software is more than 3 years old and is way outdated. For the time being, I do not intend to release a newer version.

There will be a new page with daily puzzles! In fact, as of tomorrow, you will be able to download Daily Hidoku puzzles from this site! For those unfamiliar with Hidoku, check this category.

I intend to start creating more puzzle types: Hitori and Nurikabe are next in the queue! Stay tuned for updates.

I intend to publish a number of new books as well as new volumes of the old ones. Very soon a Picross (Hanjie, Griddlers, Nonograms) book is coming, followed by new volumes of the “Revenge”, Samurai, Hidoku and KenDoku. I’ll keep you posted.

That’s it for now. Have a great New Year’s Eve! Best wishes!

UPDATE: Sorry folks, for various reasons, I will start posting the daily Hidoku puzzles from around the 15th of January.

Here is a brand new Sudoku variation as a special Christmas present. Hope you will like it.

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.

Merry Christmas folks!

UPDATE: A new “Sudoku Straights” puzzle will be shown every Friday on the Sudoku page.
