Tapstone -Shading Logic Puzzle

Shade cells to form a single connected shape — no 2×2 block allowed anywhere. Clue cells stay unshaded and show one to three numbers: reading that cell's neighbors clockwise, the numbers are the lengths of the shaded runs touching it. Work outward from what the numbers rule out, and the whole shape comes into focus. There is no guessing. Each of the 150 puzzles has been checked by a real solver to guarantee a single, logical shape — a path of pure deduction always exists from the first cell to the last.
