Theme: Clue Symmetry and Logic

Author/Opus: This is the 184th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Standard Cave rules. Also, the Cave must be divisible into pentominoes. Not all pentominoes need to appear, and pentomino shapes can be used more than once. As in Pentominous, no two identical pentominoes can share an edge.

Answer String: Enter the letters associated with the pentominoes occupying each cave cell in the marked rows, separating the rows by a comma. Use CAPITAL LETTERS, and ignore non-cave cells (Example: “WXXXT,LLUU,PPPULUF”).

Time Standards (highlight to view): Grandmaster = 3:45, Master = 5:15, Expert = 10:30
