<p>Are you talking about Squiggly Sudoku, tango? If so, here’s a link:</p>

<p>Another hardcore addict here.</p>
<p>dragonmom, I tried one of the CountOn “very hard” sudokus, and found it quite easy. I was too lazy to print it out (this would involve saving to a datastick and taking it to the computer with the printer), so I did it without writing anything in.</p>
<p>I had a book once with puzzles that required advanced techniques (e.g., “x-wing”). I wish I could find more of these.</p>
<p>I have one strategy that I came up with myself. It is not really different than the usual strategies, but somehow I find it faster. If you have a “triple” filled in (by triple, I mean 3 numbers in a row or column within a single block), then look at the numbers in the other two blocks in that line (same direction as triple) that are not lined up with the triple. If you have a number that is different than the the ones in the triple, then you know that it has to go in the 3rd block (not the one with the triple or the one with the number currently under consideration) in the same row or column as the triple. Sometimes there is only one possibility. Often this enables you to quickly fill in a few numbers.</p>
<p>Suudoku, people, suudoku…</p>
<p>From “suu” (number)</p>
<p>I can’t find it now, but I read online at one point or another why it was Americanized to one U. However, I think if you look at the links posted, you will find that one U is pretty much accepted now. In fact, I Googled two U’s and got very few hits, and Google asked me if I perhaps meant Sudoku?</p>
<p>NYMomof2 - I’m surprised you found the very hard CountOn puzzle to be easy, without needing to write anything down, but you thought the Killer ones were hard. I’m in awe of those who can do the more difficult ones without pencilling anything in. The sites I linked to earlier all have a function to allow you to “pencil in” possibilities. So I don’t think it’s cheating.</p>
<p>Try the Killer site today - it’s an “easier” puzzle. The only way to do them, though, is to write in all possibilities. (Doesn’t require a certain function to do so. Just type more than one number. For instance, if it gives a block of 3 squares and indicates that the total will be 7, you have to type in 124 in all 3 squares. The numbers will automatically decrease in size, the more numbers you type.)</p>
<p>Thanks for the links. I too am hooked on sudoku & like nymomof2 find the books unchallenging. The ones in my local newspaper get more difficult through the week, so I usually have to wait til Fri or Sat for a challenging one.</p>
<p>My very brilliant H says: “computers design them, computers can solve’em.”</p>
<p>mapesy, that’s not it, but those are good, too. The book calls is Samurai Sudoku. I love them. The others are often too easy. I also like another math puzzle. Dell calls them cross sums, but I found a book of them in Europe and I think they’re called Kakuro in Japanese.</p>
<p>I found it! Those of you looking for a bigger Sudoku challenge, try this [Samurai</a> Sudoku](<a href=“Samurai Sudoku”>http://www.samurai-sudoku.com/)</p>
<p>I love it. It keeps my wife entertained so I don’t have to.</p>
<p>binx, It takes me a lot longer if I can’t write in the possibilities. I don’t write in every number, just things like pairs that block two cells, or possibilities that are confined to one row or column. </p>
<p>I tried an Evil Sudoku, and although it took me about 30 minutes to do it, it wasn’t really hard (that is, it could be solved using elementary techniques).</p>
<p>I’ll try the killer Sudoku when I get a chance, binx. I did not understand how to approach it. I am getting ready to go on a trip, but when I get back I will try that one and the Samurai.</p>
