Author/Opus: This is the 138th puzzle from our contributing puzzlemaster Grant Fikes.
Rules: Divide the grid into 20 pentominoes so that no two pentominoes of the same shape (including rotations/reflections) share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter. An inventory of possible pentominoes is given below the puzzle.
Answer String: Enter the letter associated with the pentomino occupying each cell in the marked rows from left to right, separating the groups with a comma. Use CAPITAL LETTERS!
Time Standards (highlight to view): Grandmaster = 2:30, Master = 3:45, Expert = 7:30
