Theme: Clue Symmetry and Logic
Author/Opus: This is the 5th puzzle from guest contributor Tapio Saarinen. You can find more of his puzzles on Perplexible.
Place 11 pentominoes (no P) into the grid, rotations and reflections allowed. Pentominoes cannot cover any cells with clues, and no pentominoes can share an edge (diagonal touching allowed). All remaining white cells, including those with clues, must be connected. Number clues behave like Tapa clues and indicate the length of consecutive shaded blocks in the neighboring cells. All ?s stand for clue values 1 or greater.
Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.
