Have you tried Simple Sudoku?

Great stuff!

I did a few, then it got old fast. I get bored quickly with puzzles that. Once you figure out how to do them, I don't see the point of doing them over and over again. I was fascinated by Rubik's cube once, . . . for about 10 minutes.

That being said, our family unit did do a neat jigsaw puzzle last weekend. But I would not do it again. When we complete one, it gets glued to a backer board.

Very good.. Thanks!

I do a lot of Sudoku puzzles. The Washington Post runs one every Sunday that is five Sudoku puzzles in one, with the middle puzzle overlapping at each corner box of nine with another Sudoku puzzle for which the box is at the opposite corner.

I do Sudoku puzzles during boring lectures. I know, I'm a horrible person, but I have to say that I've gotten pretty good at them.

I'm currently writing a program to solve Sudoku puzzles. I saw a book at the local Barnes and Noble "Library" on Sudoku programming, but i was unimpressed, mainly because the techniques used could not be easily transferred to other applications. Anyway, I've always wanted an excuse to learn Prolog, and given that this is an ideal language for this problem, thats what I'm going to use. I may also write a version in Perl in order to make it easy to deploy to a web page.

That's the one beef I have with Sudoku - I'm taking 20 minutes to solve a puzzle that a properly designed computer program could solve in under a second.

I find Killer sudoku (http://www.killersudokuonline.com/) a bit more interesting and challenging, and to some extent Kakuro (http://www.kakuro.com/). Plain Sudoku gets lame fast.

Just finished a "hard" puzzle. Once you work out an approach algorithm, it's just a matter of time. There's always at least one square you can solve using one of four methods that are a direct result of the one rule: Fill in all blank cells making sure that each row, column and 3 by 3 box contains the numbers 1 to 9. Once that square is solved, there's always at least one more.

I always tackle it by finding the one square with the most numbers in the intersecting row and column. Not always the one that can be solved, but it's usually the one.

i love sudoku it is cool

[Zentisan]

I do love suduko. And any hare-brained guy/guyies can figure out that's its more than just rows and columns.

Do not post hate. this is just a opinion.

Do you use family photographs? Nice!

yeah...we bought (pls don't ask why) an electronic version ...palm-sized.
i tried a few times...no dice...so i press ans key...hey presto..all filled in....nanoseconds...i'd rather tackle the crosswords and word plays.

[Zentisan]

I was just wondering... like the 9x9 sudoko is kind of a magic square. what might be about the largests sq we can make? And why?

[mahesh]

i would have thought using digits one through nine, limits the scope. strictly speaking when deployed in a square.

have seen other shapes, intercepting digits. that then would depend on the pigment of one's imagination.

I solved a 1 X 1 sudoku once. Then I lost interest.

Is the solution unique?

[mike alexander]

No, that was the problem. I had a big argument with Warren Platts who insisted that since the solution wasn't unique, then all Sudoku are by extension suspect, and might destroy the world.

[Homo bibiens]

This Warren Platts sounds like a sensible fellow.

I agree. I also like Kakuro (http://www.kakuroconquest.com/).
