There is a naked triple -- 3 digits that can only go in 3 cells -- in row 7. After that, it shoulld be easy.

Thanks !! I saw:

Code: Select all

67(9) 27  125 | 4  157  8  | (6)79  3  6(7)9

This exclude the "7" in r7c2 (and also in r7c5)

Arg ! I forgot to check "hidden"...
You are right... It exclude the "2" in the r7c3 and therefore the "2" in this box can be only in r7c2.

Thanks a lot.
