Tapstone -Shading Logic Puzzle

TAPSTONE GAME

About this game

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.
