Swordfish
As promised, I implemented the Swordfish classic Sudoku solving technique in my Perfect Sudoku software and generated a few puzzles. I just posted one of them on the Daily Sudoku page. However, I ran my generator and generated a couple of thousands Killer Sudokus and NONE of them required Swordfish, just as I speculated before. […]

Weekend Special – Insane Killer
Ok thanks for all your comments to my post regarding the difficulty of some puzzles. I completely changed the rating system and created a large number of puzzles just to test it. As promised – I just posted an extra killer puzzle, rated (by the new rating system) as INSANE. It’s actually one of the […]
Subtraction combo
Udosuk, one of our visitors who is most active in giving hints for the puzzles we post here, has made a suggestion for a new solving technique for Killer Puzzles. He calls it “subtraction combo”. I’m posting his explanation here (slightly modified): I’m proposing a trick which I think many players already knew, but I’ll […]

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)!

Comments
There were quite a few comments from our visitors, especially on the Daily Killer Sudoku page, which makes that and other pages load slow. Therefore, I have moved some of the old comments to this new category. If you’d like to read what other people had to say about our puzzles you may find the […]

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 […]

Take it Easy
I realised that I’ve never posted an “Easy” Killer puzzle. So, in preparation for the weekend I just uploaded a new puzzle, rated Easy. By the way, which ever “difficulty” is in the lead tomorrow – I will post a puzzle with that rating. It look like it’s either going to be “IQ” or “Insane”. […]
New poll
I’m closing the Mobile phone poll. I’ve been so busy with other things so I’m not sure when will I get my head around implementing Perfect Sudoku for mobiles. Here are the results: Anyhow, here is the new poll – choose your preferred level of difficulty for our Killer puzzles. It will affect which puzzles […]
