On this page we show a variety of Sudoku puzzles on a daily basis. The focus will be on Jigsaw Sudoku Outside Sudoku and TriDoku, but there will also be consecutive, non-consecutive, odd/even, hyper, greater/less than and other Sudoku variants.

We don’t post Killer Sudoku puzzles here – there is a special Daily Killer Su Doku page dedicated for them.

Make sure to also check the Main page of this site, because that’s where occasionally other puzzles are posted: Kakuro (Cross Sums), CalcuDoku, Overlapping Sudoku, Picross (aka Hanjie, Griddlers, Nonograms).

Instructions and rules for Sudoku variants

1. All standard Sudoku rules apply.
2. If you see an “X” across the puzzle (diagonals) it means that numbers cannot be repeated on those diagonals.
3. In “Hyper Sudoku (Windoku)” puzzles, there are 4 extra “nonets”, marked in light grey. All 4 of them must also contain all numbers 1-9.
4. In Jigsaw Sudoku puzzles (aka irregular boxes/nonets), the nonets have been transformed from usual 3×3 squares to “jigsaw” nonets. The usual 3×3 boxes do not exist!
5. Jigsaw Windoku puzzles are a mixture of the two puzzle types explained above.
6. Here are the rules and instructions for Sudoku Straights puzzles.
7. Here are the rules and instructions for Outside Sudoku puzzles.
8. Difficulty levels in increasing order: EASY – COOL – THINKER – BRAIN – IQ – INSANE

    I receive the emails with the puzzles. I enjoy doing them but can we have the solved puzzle also? When I am doing one I never done before it helps me to discover my mistakes when I get stuck. Thanks.

      Clare, I will take your suggestion into consideration and make sure that there will be more daily Tridoku puzzles in 2012! :)

    Variant on 2/6. What do the black and white boxes mean?

  6. Posted February 6, 2012 at 5:27 am | Permalink

    Grey boxes=odd numbers
    White boxes=even numbers
    Just like in the Outside Sudoku book :-)

    What are the rules for todays outside sudoku? What are the shaded areas for?Thank you

    Would you please provide the name of the type of variant puzzle? I feel this would be very helpful in order to look up rules for the puzzle type. Thanks

    What do you call today´s variant and how do you solve it? Thanks, Fernando

    • Posted April 18, 2012 at 9:31 am | Permalink

      Ellen, Fernando,

      Today’s puzzle is a Hidoku puzzle. Fill in all numbers from 1 to 100. Consecutive numbers must touch horizontally, vertically or diagonally.

      Hope it helps. :)

    I understand non-consecutive sudoku but what do the dark bars represent? Apparently this is some sort of variation. Thanks!

    • Posted May 8, 2012 at 12:16 am | Permalink

      Ellen, the (non)consecutive sudoku puzzles with dark bars mean that the numbers connected by dark bars must be CONSECUTIVE. So it’s both a consecutive sudoku and non consecutive sudoku, because all other numbers must still be non-consecutive.

    Dear Djape,
    i need no book to read, i need no alcohol, i need no cigarettes, i need no TV, i need no sleep, i don´t need anything – to relax i just need zero killer sudokus level IQ from Djape.
    So, where is the book?

    Best regards from Germany- yours Denise

      Dear Denise,
      I love your comment! :) But I must say you disappoint me a little – you didn’t look hard enough. There is already a Zero Killer book and it’s also available in Germany!!!
      http://www.amazon.de/dp/1438284306?tag=thehomeofperf-20

      So what are you waiting for? There is only one left in stock, so go grab it! :)

      Best,
      Djape

        Dear Djape,
        sorry for disappointing you- i should better keep you in line. I´ve already bought ALL of your in Germany available books- including zero killer sudouku maximum challenge. I didn´t need the pages 104-112 and the really entertaining puzzles started with no. 41. This book is from 2009 – now is 2012!!!You can´t let me suffer for another 3 years!
        I really need some new stuff very hardly- i´ve started smoking, reading books, drinking alcohol – and talking to my husband. Denise

    The puzzle for 6/27/12 did not appear on the website. The puzzle for 6/28/12 did not appear also. The solution for 6/27/12 puzzle did. I should say any puzzles on the website have not changed since 6/26/12. What happened?

    Thanks so much for another great triangular puzzle! I really enjoy solving these, especially the COOL and THINKER levels right now. With more practice, I hope to be able to do the harder ones.

    On 25/09/2012 was published in this category a classic sudoku with a THINKER level. It seems a sudoku without solution or, at least, a solution with logic. I tried everything including X-wing! I got 27′s, 47′s and 247′s in every place but without success for a logic solution! Anybody can help me? I don’t like to do sudoku by tentatives!

    • Posted September 27, 2012 at 11:29 pm | Permalink

      Fernando, you see the thin grey lines across the puzzle? It means it’s a diagonal sudoku! No repeats are allowed on the diagonals! :)

      This is a sudoku variants page, which means that I rarely (or never) post classic sudoku puzzles here.

      Cheers

    Current puzzle doesn’t seem to be showing up “for the first 15 minutes of every hour” yet. Problem? Can see it on another machine that I did a “Like” from.

    Haved liked on FB and checked the first 15 minutes of the hour. Unable to see the sudoku variant.

    Been on the site since 1200. It’s now 1205 I’ve gotten off the site and back on twice, still no puzzle.

    I will not use facebook. They spy onto your email lists, sell your name to spammers, track, store and report your internet activity. All this leads to identity the ft. Facebook privacy violations are well documented. Please stop using this as a precondition to puzzles or the archive.

    Why the Facebook requirements?

    • Posted November 22, 2012 at 2:25 pm | Permalink

      I’m trying to get more visitors to the site. If you share on facebook, more people see and search engines pick up more pages. That’s the only reason. :)

      Like I said – you are downloading puzzles from my website for free, which means you like them. So I’m asking to confirm that by clicking on the “Like” button. :)

      Thank you!

        This Facebook requirement is the best way I know of to drive people AWAY from your site, including longtime fans.

        • Posted November 30, 2012 at 8:20 am | Permalink

          Enxio, aren’t you being a bit harsh? It’s not a requirement, because you can still access the puzzles without any problems 50% of the time. Also, it IS going to go away almost completely very soon, in about a month or so.

          If that’s too much for you after 7 years and THOUSANDS of FREE puzzles, than I would be really sorry to see you leave.

            Pedja, I don’t fault you for trying to boost your Internet exposure (search engines and all that). I just think that, while the Facebook thing may have sounded like a good idea, it’s having the opposite effect of what you intended, not to mention that many people are having trouble getting it to work. I really don’t see how that’s harsh. Nor am I the only one to have expressed this sentiment. I’m glad to hear that it’s going away, because I think you’re shooting yourself in the foot here.

            And I’m NOT able to access the puzzles 50% of the time. The puzzles never appear during the first half of the hour, no matter how many times I refresh the page, regardless of my “liking” the Facebook page or not. I’m not the only one having this issue, either.

            Please, rethink this whole Facebook idea, and find another way to increase your Internet visibility, one that doesn’t punish, or at least infuriate, your current user base (you know, the ones you’re asking to promote your site).

    Thanks for this book. Looking forward to solve some more books from your side.

    Hi,

    Is it possible to place in this section,with more frequence, DIAGONAL SUDOKU´s? A high degree of difficult will be appreciated!

    • Posted February 6, 2013 at 11:13 am | Permalink

      Hi Fernando,

      Thank you for your request for more Sudoku X puzzles. I always take that into consideration when posting new puzzles. So, this counts as +1 vote for Diagonal Sudoko!

  26. Posted March 24, 2013 at 4:32 am | Permalink

    really grateful for the archive, can’t get online every day
    something has gone wrong with the variants this week; Monday 18 march is missing and IQ!Jigsaw for 20th and 21st are identical puzzles despite different file names
    Hope this can be fixed, thanks

    • Posted March 25, 2013 at 8:41 am | Permalink

      Bati, thanks for pointing this out. I will try to avoid mistakes of this sort in the future.

      • Posted March 26, 2013 at 3:45 am | Permalink

        It’s fixed! I’ve now got both IQ jigsaws, thank you. What a treat! I’d love more IQ tridoku/jigsaw/outside, thanks
