Author/Opus: This is the 89th puzzle from our contributing puzzlemaster Murat Can Tonta.
Rules: Place the twelve pentominoes into the grid, rotations and reflections allowed. Pentominoes cannot cover the numbered cells, and they also cannot touch each other (not even diagonally). Numbered cells indicate how many of the surrounding cells (including diagonally adjacent cells) contain parts of the pentominoes.
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.
Time Standards (highlight to view): Grandmaster = 5:30, Master = 7:15, Expert = 14:30
