DJ Ape .Net – The Home of Perfect Sudoku

This is off-topic, but I really want to recommend and suggest you to download the Firefox browser, which provides many features that aren’t available in other browsers. I’ve been using it myself for quite sometime and am perfectly happy with it. Now it comes with Google toolbar for better browsing, too! You can download it by clicking on this link bellow:

And yes, it is an affiliate link (I get paid for showing this on this website), but until now I’ve been showing the “Spread Firefox” button – which is the same thing except that it was shown for free and it was a sincere recommendation.

Try it and I’m sure you’ll like it!

I forgot to mention – it’s absolutely FREE!

Another overlapping variation – now with 3 Sudoku X puzzles.

Warning: This puzzle is quite difficult even that it can be solved using only basic techniques. You must work on all three puzzles in order to get the solution. Also, I think you might get confused about the “fourth” puzzle which you might think exists in the center of the entire puzzle. Well – it doesn’t! The middle 9×9 does not have to be a valid puzzle! Look at the diagonals – they well define which 3 puzzles must be solved.

Instead, a very similar yet different variation – the true Wing X. This is not to be confused with the X-Wing solving technique!

Wing X for Saturday, November 26 – this is the only place you can find these kind of Sudoku puzzles!

Basically, not only do you have to fight against 5 interconnected Sudokus, but you also need to be carefull about the diagonals: ALL diagonals in the puzzle must contain one occurrence of each 1-9 digit. The diagonals are marked in the puzzle so you wouldn’t forget about them.

I have just completed a new enhanced version of my puzzle generator. We can now create any kind of overlapping Sudoku puzzles (Samurai-like) – that is, with any number or arrangement of 9×9 classic Sudoku inside.

Here I’m posting my first such puzzle – I’m calling it Double Trouble (the puzzle formerly known as “doubled-doku”). To spice it up a little extra, I made it “X” so be careful about the diagonals!

Comments, suggestions?

Another proud announcement – Compupress, a publishing company from Athens, Greece, will start printing our puzzles in their magazines in December issues of their bi-weekly and monthly magazines.

The puzzles will include all of the following: Sudoku X, Samurai and of course Killer Sudoku.

They will be printing our puzzles every month.

If you are interested in publishing our puzzles in your newspaper/magazine, just drop a note to us.

I posted another classic Sudoku that requires Swordfish/X-Wing solving technique. You should practice this technique because at some stage I might post a Killer Sudoku that will require you to use this technique to solve the puzzle. Maybe.

Of course I also posted another Killer – it’s a Brain X.

Have fun.

It is with great pleasure that I announce that two books with Perfect Sudoku puzzles have been printed and will reach bookshops very soon. I have hinted this before but it’s now official. Both books will be available in bookshops in Portugal only, thanks to Via Optima publishing house from Portugal. They will appear there in about one week but no later than Friday, November 25.

The first book is called Sudoku K and it contains 101 Killer Sudoku puzzles created by Perfect Sudoku software and with all levels of difficulty. Here is the cover page for this book:

The second book is called The Lord of the Sudokus and it is a collection of 365 sequential Sudokus plus 1 bonus puzzle about which I’m not going to reveal too much. The sequential puzzles are just like the ones that I posted a few days ago – in case you haven’t tried them you can have another look. There is also a story that goes along with the puzzles. This is the book cover:

We are working on making these books available to people from other countries too. They will be released in PDF form and sold through this website. More details about that in the coming days.

I have another announcement to make – as of tomorrow – Friday, November 18, our Samurai puzzles will be published every Friday in Washington Express a free daily commuter newspaper that is published in Washington D.C..

It is highly likely that there will also be Killer Sudokus published in the same paper very soon

So if you live or work in that area, look for your free copy of Washington Express around your metro station!
