Diagonal Sudoku
Can you imagine that I never posted a plain Diagonal Sudoku X puzzle here on the main page? I’ve posted a few Diagonal Samurai Sudoku puzzles and of course I often post Sudoku X puzzles on the Sudoku Variants page.
Well, that’s about to change. 🙂 Here is a Sodoku X puzzle which is not too difficult, but it’s a challenge. It can be solved in many ways, using classic Sudoku techniques, but also using some special techniques that apply only to Diagonal puzzles.

Non Consecutive Sudoku
As you may have noticed, I’ve been trying to make the navigation on the website a bit easier. In the right hand “sidebar” you can now find quick links to most popular kinds of puzzles.
The “Sample Puzzles” category contains hundreds of puzzles which I’ve been posting since 2005. A nice feature is that when you flick through the pages of this category, you will see small images of the puzzles, so you’d know what to expect.
And as promised, I will continue adding more basic or “staple” variants of puzzles that I never posted before in the sample puzzles category.
One such puzzle is Non consecutive Sudoku. I’ve posted a few variants of this variant :), but never a plain non cons puzzle. Of course, they do often feature on the Daily Sudoku page.
Anyway… here is the puzzle. The difficulty is just enough, I think, challenging but not too difficult. What do you think?
And of course be warned: it looks like ordinary sudoku but it’s not! It’s a non cons, meaning that you can’t place two consecutive numbers next to each other, neither horizontally nor vertically.
Oh… and I’ve removed the “Like” button requirement for new puzzles. For old puzzles you do have to click “Like” in order to access them. This is purely so that more people can reach those puzzles, because by sharing you notify other people of something. And as promised, the Killers, Samurais and Variants are easily accessible again, except on Tuesdays when they are accessible 50% of the time and the other 50% of the time you should “Like” them first.

Kenkuro
Kenkuro puzzles are something that I invented (or at least haven’t seen them elsewhere) and I will try to promote them more. So, starting January 1, 2013, there will be another daily page with Kenkuros!
Here is a sample Kenkuro for today. I will also send it later today in the newsletter.

Hyper Sudoku
I’ve realized that there are several “staple” Sudoku Variants that I’ve never posted here on the main page.
One of them is Hyper Sudoku. Although I never posted a “vanilla” Windoku puzzle (Hyper Sudoku = Windoku), I have posted, for example, a Hyper Samurai Sudoku Windoku.
So… to start rectifying this issue, I will be posting a series of these “basic” Sudoku variants puzzles in the next few days.
What do you think of Hyper Sudoku? Would you like to have a book full of them next year? 🙂
The rules of Hyper Sudoku Windoku
– follow the same rules as in classic Sudoku – in addition: there are 4 “windows” in each puzzle, shaded in grey. Numbers cannot be repeated in any window! Each window must contain all numbers from 1 to 9.Hyper Sudoku Windoku for Thursday, November 29, 2012 – Difficulty: THINKER

Flower Jigsaw Sudoku
It’s been a while since I last posted a Weekend Special puzzle. This time it’s a Flower Sudoku in Jigsaw Sudoku format. Or Jigsaw Sudoku in Flower Sudoku format? I don’t know. There was one Jigsaw Flower Sudoku variant posted a couple of years ago.
The puzzle for today is rated COOL. Make sure to use the Twin Nonets technique. You can also use the Law of Leftovers technique, but you don’t have to.

Introducing Kenkuro puzzles
In my previous newsletter I sent out a puzzle that is very special because it’s a completely new kind of puzzle.
It wouldn’t be fair if I didn’t share it with all of you. So, if you want to see what the puzzle is and if you like either Kakuro or Calcudoku or Killer Sudoku, make sure to see the first ever Kenkuro puzzle.
Make sure to subscribe to my newsletter in order to receive future special puzzles that I post!
UPDATE: The puzzle and the solution to Kenkuro are available here. Kenkuro puzzle and solution
Outside Twodoku
Here is something completely new! 🙂 A new variant of Sudoku puzzles, previously unseen anywhere!
Two overlapping Outside Sudoku puzzles arranged in the Twodoku format. What else needs to be said? 🙂 Well, just that some clues had to be left on the inside, too. Those are regular Sudoku clues and you use them as usual. The clues outside of the grid tell you which number(s) MUST appear somewhere in the 3 closest cells. This also means that they can’t appear in the 6 cells farthest away.
That’s it. Use all clues in order to solve the puzzle. If you have doubts – ask here!

Insane Killer Sudoku – by Daniel Skillin
Today we have an extra special puzzle – a Killer Sudoku puzzle by a guest author. It’s been a while since I last posted such a puzzle. I really appreciate the enthusiasm of the visitors to my site and your efforts to make good quality puzzles and share them with others.
Today’s puzzle was created by Daniel Skillin. It is rated INSANE – but we all know that with the fiendish puzzles it is always a personal impression that matters. There is no absolute rating system for Samunamupure puzzles that would objectively evaluate a particular puzzle’s difficulty.
So, how tough do you find this Killer Sudoku puzzle?
If you have created a puzzle and would like me to post it here, just send an e-mail! 🙂

Twodoku
Here we go… another “classic” Sudoku that I can’t remember posting before.
Twodoku is a Gattai-2 puzzle, which means that there are two overlapping Sudokus. It’s a tough one, I think. In order to solve it, you should use all classic Sudoku solving techniques, but it would help if you also knew how to apply the Twin Nonets technique.

I realized that I never posted a classic Butterfly Sudoku puzzle on the main page of the website. A few of them have been posted on the Daily Sudoku Variants page, but the puzzles posted there disappear from this website after a week.
So… to rectify this issue, I am presenting you with a
Butterfly Sudoku Overlapping Sudoku Variant Puzzle
There are 4 classic Sudokus inside this one. They overlap heavily. Each one of the four starts (or ends) in one of the corners. So… even though there are 12 cells in each row and column, first 9 belong to one sub-puzzle and last 9 belong to another one. Make sure you are clear with the rules, or ask me to clarify again. How do you solve Butterfly Sudoku? Well, all classic Sudoku solving techniques can be used; in addition, Twin Nonets are basically a must for this layout. If there is an interest in these, I might publish a sudoku book full of Butterfly puzzles 🙂 Difficulty: THINKER Click on the puzzle thumbnail to access the puzzle.
