Is there anyone else here who absolutely loves playing sudoku? It's a puzzle game where players have to fill in numbers in a grid to meet a certain pattern. It appears daily in many newspapers, the same way that crossword puzzles do:

I saw it for the first time in the newspaper a few weeks ago, and I'm totally hooked now! I often tear out the page that the puzzle is printed on and walk around during the day with the game in my hand, trying to solve it. I can spend hours playing it. It's just so addictive!

So far, I've solved almost all the sudoku puzzles I've come across, but there's been a few that have got by me. Oh well, guess you can't win em all...

I looked at it and it seems like much more trouble than its worth

I'm quite good at those puzzles...even the really tough ones :D I manage to solve every single one I start. You're supposed to fill in the grid so that every row, column, and 3x3 box contains the numbers 1 through 9.

I hate 'em.  My eldest daughter is an addict  :o

I tried them for a little bit, I did one of medium difficulty, and now I have retired from sudoku

Has anyone ever seen the "Number place" puzzles in the Dell puzzle magazines? Sudoku is just like those.

I'm proud to say that I was just able to solve this particularly difficult sudoku puzzle here:

It took me about 4 hours, but I was able to do it! Yay for me!  :)

....takes me forever to do them, and when I finally think I've solved one, (where's the pulling out hair icon above, with apologies to any Trich sufferer's, if the expression is offensive to you),
frustrating!
>:(

My math teacher was one of the first on this... I don't like them.

My dad has started doing those puzzles lately. Often times when he's stuck on one, I'll finish it.

Although I love crossword, I've never tried the sudoku puzzles. I've never enjoyed working with numbers, and I'm afraid that if I tried one of those sudoku puzzles, this would happen to me:

"MY HEAD A SPLODE"

I did one this morning and was thinking of posting a thread about them-but I see that someone has beaten me to the punch.  I like doing them-as well as crosswords, cryptoquotes, logic problems, etc, etc.  Yes, I like puzzles. It keeps the mind engaged.

I've never enjoyed working with numbers,
I'm the total opposite. I've always enjoyed working with numbers.

Is that the ones where you put the numbers in to add up to a certain #?  If so, I have done a few of those. Of course I need a calcalator to do those.  At least with Sudoku, you don't need to add.




Cat

Is that the ones where you put the numbers in to add up to a certain #?

No, that's a "magic square."

With Sudoku, you need to put the numbers 1-9 in a 9x9 grid in such a way that no number is repeated in any row, column, or 3x3 box.

I know how to do Sudoku (did one just this morning that was in the paper). Like I said, no adding necessary.

Exactly. :)

Our local paper just started putting them in yesterday. So now I can get a daily fix.  ;D

I got a book of 600+ sudoku puzzles for Christmas...I've already done at least ten of them. They range in difficulty level from easy to "challenger", which is supposed to be very difficult, but I'm always able to figure out the difficult ones. There are also some "super challenger" puzzles that utilize the numbers 1 through 16; in each of those, those numbers must appear exactly once in each row, column, 4X4 box, and diagonal.

I couldn't get the one that was in the paper today. I must have worked on it for hours. I will try again later.

Must've been a tough one or something.

Yeah it was. I tried it again this morning and I STILL couldn't get it.  >:( I finally cheated.  ;D




Cat

I love Sudoku, it isn't so tough that you know you can't do it, and it keeps you engaged.
I asked for, and got a book them for Christmas.  Something to while a way the time when
you are really sick of the book you have been trying to read but decided it really was just
too boring.

Just bought a book of these to give to my husband.  He can't do 'easy' sudoku puzzles only the hard ones so I thought this would add an extra challenge

I think hubby started doing them in either The Sunday Times or The Telegraph on Saturdays.  We don't buy a paper very often but if we do it's one of those two.  With all the supplements there's enough reading to last at least a week!

Now I know why they call it "killer"! :o

I suppose I could try my hand at one of those at some point... I doubt that I'd do very well.
