Yes, I printed it off but I was at work at the time so didn't get much chance to look at it. I'll have a go tonight - I've not looked at the answers.

That looks good to me John :)

Willow....doing one of these reminds me of doing the duty rotas.......you thought you had it all covered and then you found you hadn't.......I hated doing those damn things...so why do I torture myself with this for FUN...?

Did it! Good one Willow it had me going for a while. Are you going to do some more for us?

Re: Here's a 9x9 Sudoku for the experts.
 

It's quite a challenge creating them but fun too so I'll try to find time to do more. I'm out most of tomorrow though.

It makes a change from Dingbats even though I did promise to come up with a new batch of those too. :)

Re: Here's a 9x9 Sudoku for the experts.
 

My solution was very similar to JohnW's, but the middle line of the top middle box reads 679 (instead of 976) and the top line of the middle middle box reads 926 (instead of 629).

I checked every single line and box to make sure it was ok - is there a quicker way?!!

Funnily enough there are a couple of possible variations of this one and I did try really hard to make sure there weren't!

The 6s and 2s in the bottom left are interchaneable so you could have:

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


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

Willow,

Are these puzzles supposed to be solved by deduction alone? I got so far with deduction, but then had to take a chance and make a guess on a couple of numbers. I think there were 6 & 4 in a 'nine' square that I found impossible to determine which, of two, they went in, even though they were the last two numbers in a square of nine. The first time it didn't work out so I swapped them around. It thus became a trial and error type solution for a while. Is that how it is supposed to be? I found the best way was to set up a spreadsheet in excel and any time I inputed trial and error numbers I did them in a different colour so I would know they were debatable.

:D I just use a pencil and a rubber, but yes they are supposed to be solveable by logical deduction.

It's hard to try to make sure of that though because when you're making one you have to look for loopholes and I obviously didn't see any.

Maybe there is a better way than my brain.

I am so addicted to those puzzles.............
