In the Killer Su Doku category you will find more kinds of these puzzles, including Killer Samurai Sudoku, Killer TriDoku, Killer TwoDoku and other variants.
Make sure to also check the Main page of this site, because that’s where occasionally other puzzles are posted: Kakuro (Cross Sums), Jigsaw Sudoku, Outside Sudoku, CalcuDoku, Picross (aka Hanjie, Griddlers, Nonograms).
Instructions and rules:
1. All standard Sudoku rules apply.
2. Numbers in “cages” (dotted lines) must add up to the cage sum indicated for that cage.
3. Numbers CANNOT be repeated within a cage, even if it is possible by other Sudoku rules.
4. If you see an “X” across the puzzle (diagonals) it means that numbers CANNOT be repeated on those diagonals.
5. Difficulty levels in increasing order: EASY – COOL – THINKER – BRAIN – IQ – INSANE
Killer Sudoku solving techniques are explained here:
Rule of 45: Innies and Outies
Cage Splitting
Complex Innies and Outies, part 1
Complex Innies and Outies, part 2
Finally, if you need help with cage sum combinations, use the Killer Su Doku, Kakuro and CalcuDoku calculator.
Previous puzzles are available in the archive
Enjoy!

The daily puzzle did not update yet for January 2?
Still no update….Two days without puzzles….Going through withdrawal! Everything ok in the home office?
I’m missing the new puzzles, too. Maybe the “home office” is taking a well-deserved holiday? I hope they’ll be back soon.
Patricia, you were right, I did take a short holiday and forgot to update the daily Killer Suduko puzzles. Now I am back and the puzzles are back.
Welcome back, hope you are rested. Now you see how important your efforts are to your followers. Thanks for everything…
Glad to see a new puzzle today. Welcome back!
I love these sudoku puzzles. Thanks!
Thanks for these puzzles.
Did something change in the way you are posting the daily puzzle? Both yesterday and today I have not been able to view, download or save it – thanks
Thanks – everything seems fine again – I really enjoy these puzzles
As requested, I have liked you on Facebook, but still no daily killer to be seen. It says to unlike and like again, but how do I unlike?
Mike, just point the mouse to the “Like” button and there should appear a small “x”, which, when clicked, “unlikes” the page. Then like again. You might need to reload the page afterwards. If it doesn’t work let me know.
This is utterly infuriating. I do not have facebook. I do not want facebook. I will not subscribe to facebook just to get a puzzle that I used to be able to get just by going to this website. Fix it or you’ll lose a follower.
I agree Susan – utter nonsense!
I totally agree—this is crazy having to sign in at a certain time—i enjoy my privacy and love DJAPE, but willl never become a Facebook user.

This Facebook thing is not working!
I have “”liked” and the variant still does not show, even for the first 15 minutes of the hour!
At first the Killer showed up and I could print it, and now that does not appear!
I access the puzzles from work in my lunch break – which is from 12:30 to 13:30, and facebook is blocked at work (and even if it wasn’t, I would never use it), so now I can’t print the puzzles off to take to lunch with me. Thanks!
DJA did email me, and said that he had changed the 15 minutes to 30. I emailed him back as this initially only applied to the main killer page and not the archive, and yesterday I was able to access the archive just after noon GMT. I thnk he has recognised mine and numerous other comments in this thread and responded – well done for taking notice of the users!
No puzzles today? All I see are ads. Also can’t get to your archive.
What’s up?
DJA has chnaged the rules and you have to be a user of facebook – aaarrrgh!
I am a Facebook user, and I can’t access it either.
Sorry, but with this change you will loose all people – like me – who like your sudokus but do not want to be member of facebook (for good reasons!).
It’s 8:04 on 11/23. Daily puzzle is not displaying!
8:06 and puzzle not displaying
Ellen, you need to refresh the page. Hit SHIFT+Refresh (reload). It should work.
Are you receiving payment for every new Facebook user you sign up?
No, Jean, nothing like that. In fact, I do not ask you to sign up to Facebook! I ask you to “like” my page if you are already a Facebook member. If you are not a Facebook member, you can still access the daily sudoku puzzles from :00 to :30 any hour of the day!
I tried to access the puzzle at 08:25 PDT today and it didn’t show up. The Facebook like doesn’t seem to work using Firefox. I had to switch to Internet Explorer to get the puzzle.
DJ – I have bought 5 or 6 of your books over the years. You are going to lose a valuable customer if you continue with this Facebook nonsense.
Frank
Frank, what you just described is CERTAINLY a caching issue in your Firefox. You need to “force refresh” by holding the SHIFT key while pressing the refresh/reload button.
And like I said a couple of times already – the whole Facebook like thing will likely go away in about a month or so. So, please bear with me. Thank you!
I like your puzzles – well the IQ ones anyway – and wouldn’t mind paying for them. But I am not a Facebook member and don’t want to be. I can’t like them on Facebook and it’s painful if I can only go to your site for 30 minutes every hour. Please change this!
Jeff, come on, please don’t exaggerate, it’s not really “painful” to visit the website during the first half hour.
Also, like I repeated many times, this “like” thing will go away, or at least will be much reduced, in about a month or so, definitely on January 1, 2013, if not before. So, please, bear with me for a little longer!
Thanks and regards
I tried to view today’s Killer at 6:25pm, no luck.
I am another avid fan of this website who does NOT use facebook. I’ve purchased all 6 killer books and 4 killer samurai books. I’m looking forward to the “facebook like thing” disappearing.
I’m with you.
Tried again at 7:03, and the puzzle did appear. Thank you, Djape!
your web site cant tell time its 420 in the morning and last i checked that the first 30 minutes an this page will not load, like unike, nothing. Where do i find the HATE button on facebook
You will also lose me as a fan unless this Facebook thing ends!
It has ended, hasn’t it?
Hi DJape,
Lately your Zero Killers become very difficault (high IQ levels).
Can you reduce some of the puzzles to low IQ and even BRAIN levels.
Another wish is Zero Killer X puzzles, I never saw this type of puzzle in your site or books and I bought almost all of your books
.
Uh… oh… I’m in trouble!
Frank, see the comment from Susan, right below this one. And what can I do now? You ask for slightly easier puzzles, Susan is asking for more difficult ones. And how can I solve this puzzle you are presenting me? 
Well, I guess I have to keep doing what I have been doing… posting puzzles of various difficulty, so everyone can choose what they prefer.
Hi djape
My opinion is that your low IQand BRAIN levels Zero killers are more fun and enjoyable to solve, I think that most of the regular solvers are not able to solve high IQ levels. The advantage of your site is that is for regular solvers that wants to enjoy and spent one or two hours in the weekend to solve the puzzle.
Frank, you are probably right. It is impossible to please everyone with one puzzle. I try to post something for someone.
But I will certainly take your comment into consideration and try to post some easier Zero Killers in the future.
Thanks so much for your attention and for your feedback, it means a ton to me!
I love the harder IQ Zero Killers. You have only published 1 killer puzzle ever that I couldn’t solve, and that was the last Insane puzzle.
Well done Susan. I also prefer difficult puzzles myself, but I do have to publish puzzles of all difficulty, so everyone could find something suitable for them.
