Using just VH moves the X Wing on 5's in rows 3 and 8 (-5r7c3, -5r2c9) opens up a 19-2 XY Wing (with pivot at r7c3) which solves it (-2r7c12, -2r9c7).

Oh, I see. I should have realized that. I don't remember ever seeing the Draw/Play page ever supporting Squigglies. As far as I know it has only ever supported the classical Sudokus.

Thanks for the puzzle peter. First I used an X Wing on 7's (I think it was in rows 4 and 6). Then I used an X Wing on 1's (I think it was in columns 1 and 4). And I think they were both necessary?

I used the 23-6 XY Wing at r4c59,r5c8 (-6r4c7) which then opened up the 24-3 XY Wing at r4c27,r7c2 (-3r7c7) which solved it.
