No. 20 - Islands #01
I hate being sick. Puzzle Link Rules (From puzz.link ): Shade some cells on the board to form islands. 1. All regions contain exactly one island, which is an orthogonally connected group of shaded cells. 2. A number indicates the size of the island in the region. 3. Shaded cells cannot be adjacent across region borders. 4. Two regions which share a border must have islands of different sizes.
