In the above link is a Soduko in which the latest entry is a 2 in R9,C9.
I do not see the logic for placing a 2 there.

Thanks for the help

This link goes to a blank grid. Clicking Load will insert the last puzzle that I had saved. Where is the puzzle for which you want your question answered?

Sorry, here is the code.
From here on I could not go any further and using HINT it placed a 2 in r9,c9. What is the logic here?
Thanks

OK. I don't know you or your level of experience. So I'll just say to look very closely at column 7. Just ask again if that doesn't help.

Yes, thanks I see it now.
8 is the only number in c7 making 2 the only number in r9,c9.

I just started playing Soduko recently and learning it.

Thanks again for your help.

You're welcome. I'm mildly curious why the hint wasn't for 8 in r9c7 since that occurs before the 2 goes in r9c9, but I'm not going to get an answer to that and won't lose any sleep over it.

Look at 8 in C9 and B6.
