This is a Thursday nurikabe puzzle, with the clue removed. You must figure out what clue can be placed in which cell in the grid to make a uniquely solvable nurikabe puzzle.
Why Thursday? The two tapas count as Tuesday and Wednesday level (but mostly because the Wednesday level slitherlink I was planning on broke)
EDIT: A 38 clue doesn’t count. There must be at least one black cell in the solution.
Wow, the entirety of this week came out harder than intended.
