Daily & Weekly Puzzles
Since it seems that this week’s brain X was a tricky one, today I didn’t post an INSANE puzzle, but rather just an IQ. It’s still quite difficult – maybe even more difficult than the brain X. I also posted a 4×4 classic Sudoku puzzle with another “shape” in it. It looks pretty I think. […]
Welcome new visitors!
Yesterday there was a post at blogs.guardian.co.uk about Killer Sudokus and a link to our site was posted. As a consequence, we’ve had some 600 referrals from that post within 12 hours (and overnight too)! I’d like to welcome our new visitors and to suggest them to go through the previous messages posted here – […]

Puzzle difficulty
First of all, I posted a Killer X puzzle rated THINKER for today. I would like to know how difficult you find this one. Regarding the INSANE puzzle posted on Friday – I see that there has been a lot of discussion regarding it’s difficulty and the difficulty of some other puzzles posted last week. […]

You Asked For It!
As promised, I just posted a puzzle with the rating that is currently in the lead in our poll. And that, apparently, is INSANE. This puzzle requires all Killer techniques + it requires some advanced classic Sudoku techniques (match subsets etc). It does not require trial and error! I hope someone will solve it without […]

Cool your brains!
According to the comments, a lot of people enjoyed the IQ Killer posted on Friday. It’s time to cool your brains off a little, with the today’s “COOL” puzzle. For those who haven’t had enough, I posted a really tough Diagonal classic Sudoku. We’re doing quite well on the top 50 Sudoku sites list. A […]
IQ Friday
First of all, I think that the download issues have been rectified. People aren’t complaining about downloading puzzles anymore, so I reckon it’s working fine for all of you. Also, I posted two puzzles just now. The Killer is rated “IQ”. It should be challenging but not terribly difficult. You should all solve it by […]
A few words about “Perfection”
Ever since I started posting “Killer” Sudokus I was unhappy for one reason: the puzzles posted did not meet one criteria that I was hoping they would fulfill – they were not perfect. Yes, I admit that. You might wonder why I say that. Two reasons: 1) September 27 puzzle. It required trial and error. […]

New puzzles uploaded
Sorry that I missed to post yesterday’s puzzle – it has been a really hectic week for me. I also thought that the Samurai X should keep you busy for a while. Anyhow, I’ve uploaded the solutions to the previous puzzles and also two brand new puzzles just for you. I hope you notice the […]
Blank Grids
Update October 4: I noticed that the samurai blank grid might have been a bit too big to print, so I uploaded a slightly smaller version. — I just figured that you might need some blank grids to print out so you could use them when you work on these puzzles. So here they are, […]

Fiendish, anyone?
I’ve just uploaded today’s puzzles. Be warned – the classic Sudoku that I posted should be rated as ‘fiendish’, I think. If you don’t think so, have a look, solve it and rate it yourself! Let us know what you think. I promise that I will soon implement an automatic rating system and post that […]
