Hi

Check for hidden singles in columns 1,2,3 and row 5
Hope that gets you going again.

Also a more general hint. Don't forget to clean up the cages(remove redundant candidates. Especially in the bottom half of the grid there are a lot of redundant candidates in cages.

Hey para,

thanks for a response. I was solving this on paper and used sumocue just to write canditates and forgot the bottom :oops:

Anyways, you really helped me, i found some hidden singles and subsets just where you told me to look! Thanks so much, i might be able to solve it now.
