Theme: Clue Symmetry and Logic

Author/Opus: This is the 85th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place all twelve pentominoes into the grid a single time, rotations and reflections allowed. Pentominoes can touch each other, but cannot overlap. When all pentominoes are placed, none of them should be able to move in any of the four directions; pentomino movement is blocked by other pentominoes and by clue cells. Each clue cell contains the letters of all pentominoes that touch that cell, even diagonally. (A blank, black cell has no pentominoes touching it.)

Or see this example:

Answer String: Enter a single CAPITAL letter representing each pentomino appearing from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma.

Time Standards (highlight to view): Grandmaster = 4:30, Master = 7:00, Expert = 14:00
