Sudoku

Post Reply New Topic

Basicly, yes. However, its an exercise in logic rather than maths. Maths may be logical, but logic is not mathmatical.

The second link I posted for a worksheet has the numbers filled in so you can cross them off. This is how my PDA version works - you can fill in what you think the numbers might be and then eliminate them as you figure out what is not there. This is what takes me so long. I fill in the possibilities first, then go back and eliminate.

I'm trying to write a sodoku program in visual basic

Oh, superb!
Will it be able to be played online?
Maybe it could go on the puzzles page.
I hate that rubik's cube. in my lifetime i have only been able to do the traditional solution once. then i lost patience and never did it again without "cheating."

Its not very happy about working at the moment And Multiplayer? Ummm. I don't know. I could write competitive Sodoku, where it was the first to complete 6 puzzles ranging from super easy to ultra hard (and complete, therefore, a cube....)

I don't understand it. I'm a math person, but I really need a video of someone doing this or someone in peson to explain. Text directions and me don't mix well.

This link shows the solution when you pass the cursor over the puzzle.

i don't know of any sites with videos and i'd have a difficult time explaining it with spoken word.

here is the solution for he puzzle i posted:

8 4 6 1 2 7 3 9 5
2 9 5 4 8 3 7 1 6
1 7 3 5 6 9 2 4 8
5 6 9 2 3 8 1 7 4
3 2 1 6 7 4 5 8 9
4 8 7 9 5 1 6 2 3
6 3 4 7 9 2 8 5 1
9 5 2 8 1 6 4 3 7
7 1 8 3 4 5 9 6 2

i confess to dyslexia so if you see an error by all means correct it.

i am currently working on a sudoku cooperative game but it is 3-d so i dont think i will be able to post it in a meaningful way. plus i think there are a very limited number of 3-d solutions (math geniuses help out here) so it may not make sense to do a nine by nine cube. it may make more sense to do a smaller one with symbols or colors instead and gradually expand it.
oops, rambling again.
if anyone wants, i can build and post another puzzle

Sudoku is something I have got into in the last 6 months. I like to get absorbed in the fiendish puzzles in the Times newspaper as well as the 'killer' version aswell.

Yeah.. I got addicted to it and then I dropped it but I still have tonnes lying around and a mate downloaded a program that generates workable grids so he prints off tonnes of them.

i must admit it,
i am certifiable.

Acknowledgement is the first stp towards recovery.

I liked cross-sums much better. Soduku is too easy. It doesn't use any math at all - in fact I've seen software versions that use letters or colours instead.

one eyed Nueroman wrote,

I did it exactly the same way. Once and i was done, i admit to cheating a few times. but i did it once.

But later the book came out how to solve it. authored by one of our ancestors i presume.

then neuroman,



Yeah but then you'll get to contend with all the advertising being there. It would be the ideal location.
who'd come to post?


I just noticed my garage floor was riddled in solved, some not, soduko puzzles from the paper. just shhod away a cat who was about to use it as a restroom

It took me a while to get into it - and to get up to speed (puzzles that are supposed to take 10 min took me most of an hour) - but I like it - as long as I'm able to relax with it. It's harder if I'm trying to fly the coop though.

It is amazing sometimes how a "weird" and "socially inept" kid like me can get people hooked on something I love to do.

My book of Sudoku puzzles caught the attention of the Alpha-Male (read: most popular associate) at work, and now, six months and a lot of trying conversations later, practically everyone plays these in the breakroom. (In fact, a memo was passed around because mismanagement figured people were spending too much time in the back instead of on the floor helping customers.)

The fastest I've ever solved a puzzle was 4 minutes and 35 seconds, while the longest was a little over 3 hours. In my defense, that was a new 16x16 grid with the numbers 1-9 AND the letters A-G. (It takes time to switch the brain into a new pattern of thinking.)

I have yet to try Killer Sudoku.
