### SuDoku 436 (Fiendish) Oct 27

This is my second Fiendish. I am COMPLETELY stumped.

After finding THREE single candidates (in red) I penciled in all the candidates and haven't been able to crack it.

Can someone push me in the right direction?

Thanks.

Wow! Thanks Simes!

I sure didn't look at the puzzle close enough. Thanks for getting me in the right direction.
