Hi everyone,

I've been having difficulties with fully solving puzzles in the expert level of the Sudoku2 app. I've googled advanced techniques but cant't spot any of them in the app's puzzles. What techniques am I not seeing here? Any help would be appreciated, especially if someone created visuals for the attaxhed pic too.

Thanks!

There is a naked pair available in column six. After that I see an XY-Chain, and then singles to the end.

Ahhh thank you! It is the xy-chain technique I've been overlooking.
