challenging - found an xy-wing that helped solve it

Challenging hard, wish we had more like this.

Fun puzzle not too hard. What did it for me was a triplet leading to a hidden pair.

Interesting...my semicolon got edited out in previous comment.

Ditto parentheses in the following one. Why

And next, a question mark.

I solved this one hours ago on amother tablet but it didnt save it.
