After manual input into my solver.
First easiest available steps are locked singles:
Take box 3 (upper right) from grid 1. Digit 4 must be in last column, after excluding 4 from r13c7 you can place digit 5 in r3c7.
After that its only singles left.

Solution:
Hidden Text: Show
Code: Select all
8 9 3 1 5 4 2 7 6                 
4 6 5 2 7 9 1 8 3                 
7 1 2 6 8 3 5 9 4
