SPOILER rest of solution follows, I think

that means r7c8 is 6
r7c6 is 5, r7c4 is 9

r8c4 is 7, r6c4 is 4

r1c4 is 1, r1c7 is 9, r1c8 is 4, r9c8 is 9, r9c7 is 7, r9c3 is 4, r8c3 is 9, oh hell, i think it's done, wait a mo and I'll post the lot or at least what i got in grid form

classicman · 12-16-2007, 09:32 PM

I thought you did, but closed the window I was working in and punted - sorry.
You're solution seems valid to me.

Ran it through again - You're a winner!!!!

monster · 12-16-2007, 09:39 PM

I so rock. I knew that brain would come in handy one day.

*happy dance*

Chocolatl · 12-20-2007, 10:19 AM

Is that the official solution you've posted? If the 8 is wrong, something else has to be wrong, because otherwise there's nowhere for the 8 to go.

barefoot serpent · 12-20-2007, 11:02 AM

yes: the 'gray' squares are the givens, the white filled-in correctly, the red are empty or incorrect.

Clodfobble · 12-20-2007, 11:40 AM

I'm not seeing any colored squares, barefoot... I'm seeing an exact duplicate of what Chocolatl posted, with one random 8 bolded.

barefoot serpent · 12-20-2007, 11:58 AM

I was referring to the 'official' solution in #16 where:
3 4 6 * 9 8 1 * 7 5 2
8 5 1 * 2 6 7 * 4 9 3
7 9 2 * 5 3 4 * 8 6 1
*****************
2 - 8 * 3 1 6 * 5 4 7
6 3 5 * 4 7 9 * 1 2 8
1 7 4 * 8 2 5 * 9 3 6
*****************
5 6 3 * 7 4 8 * 2 1 9
9 1 7 * 6 5 2 * 3 8 4
4 2 8 * 1 9 3 * 6 7 5

The bolded 8 above is indicated as correct.

Chocolatl · 12-20-2007, 05:15 PM

Are you sure that it's officially "correct"? Is it checking it against the final solution, or is it just checking for blatant errors (like two 8s in the same column)?
I'm not trying to be confrontational, I'm just confused because I'd always thought that sudoku puzzles only had one solution each. I worked my solution out using the original numbers, and it works, so I'm just curious to see what the final official solution is if it's different from the one I got.

barefoot serpent · 12-20-2007, 05:22 PM

I just assumed it was the final, but you may be right. I've gotten others that indicate errors but I can't find the problem. So may be it's the program?

barefoot serpent · 12-20-2007, 05:36 PM

eek... I guess there are multiple solutions!

Chocolatl · 12-20-2007, 05:56 PM

Multiple solutions!? Gah. Well, there's the problem.

I checked your solution to that last one and couldn't find any problems with it either. I tried to solve it myself, working from the originals, but I ended up stuck with quite a few that I couldn't figure out without guessing. I compared them with your answers, and they're all the same -- except all the red numbers from yours are the blanks on mine.

I guess you just found a different solution that wasn't what the computer was expecting. Good job, anyway!

Tink · 12-20-2007, 09:12 PM

SD,

You need Sudoku Gridmaster for DS now that you have some on the way. I have it. Over 400 puzzles. Addicting! Love it!

busterb · 12-20-2007, 09:27 PM

I hate to poke my dumbass nose in this, but are there some basic rules? I did one from Sunday paper mag section awhile back and solution said was wrong. Across and down I couldn't find an error.
I bought an el-chepo from bigbox, but lost interest after paper said was wrong. Yeah. I'm with stupid.

Chocolatl · 12-20-2007, 10:29 PM

Buster, it's supposed to be the numbers 1-9 in each row, 1-9 in each column, and then also 1-9 in each little 9 square cube. Other than that there aren't really any rules for the basic format, as long as the numbers don't repeat themselves.
