Killer Sudoku on Saturdays!
I should’ve announced this before, but was too busy making the sudoku variants book. So… As of today, every Saturday on the Killer Sudoku page a Killer Sudoku 10×10 will be posted! Almost 8 years after I started posting daily killer sudokus, now there will be a Sumdoku puzzle on Saturdays, too! Remember to add […]

Killer Sudoku 10×10
When was the last time I posted a Killer Sudoku variant puzzle for the first time? I can’t remember. Well, nearly 8 years (I’m a bit slow, you know) after publishing first Killer Sudoku, it occurred to me that there is no reason not to add the 0 into play. So… ladies and gentleman… a […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]Butterfly Sudoku
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 […]
