This is the first one where I couldn't see a logical path. I did after proving that the middle 3 clue had to have its right shaded, but proving that needed a fair bit of trial on its left. After that though this had very nice logic with connectivity prevented through certain areas.

Tough one. Not my day i guess.
I started out correctly, but kept making same mistake every time in the top. But anyways this is just getting started, hoping to catch up score on other days.

Same as Prasanna.
And I never thought I'd say that about a puzzle ^^

I couldn't see the path in the solve, but figured it out now.

My best argument so far is: The only way to connect the two halves of the 33 clue locally leaves the 2 of the 24 clue stranded on the right, so regardless, we have to loop from the top of the 33 clue all the way around the top right to the bottom middle. This implies that R5C3 is shaded, among others. Since the 24 clue takes one of the 13's shaded cells, as does the central 3 clue, R7C3 can't be shaded.

The best bet for solving quickly still seems to be a case distinction on the central 3 (and don't mess it up...).
