This is a Nurikabe puzzle, with a twist. It must be possible to tile all of the shaded cells by nonoverlapping 1×2 dominoes.
Puzzle 395
I got sent this nice variation idea by Jack Brennen.

Did you do this one? Actually, the person who proposed the variation sent it to mathgrant and I both (among others), and mathgrant made that puzzle in response.

Btw,this was pretty cool initially,with the domino logic playing a good role, then i didnt have to use it for the remaining 50%.

Nice puzzle. I had the opposite experience looking at the above comment, I started off with the bottom right which is fully Nurikabe, and then it was nice to have the domino logic help me out from elsewhere when I got stuck.

Nice puzzle. 5 months later, forgetting that this puzzle would have existed for five months before I would get the idea independently, I made one.
After redoing both, I find out that we use different tricks, but yours actually feel somewhat easier. I’m not sure. Going to ask your (as in MellowMelon’s and all readers’) opinions.
