or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between a composite mode for line/edge drawing and a letter entry mode.)

Theme: Words

Author/Opus: This is the 55th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Divide the grid into 20 regions each containing 5 cells. Regions with the same shape (including rotations/reflections) cannot share an edge. A region may contain at most one letter clue. Each letter is false; the correct letter which indicates the shape of that pentomino is either one higher or one lower in alphabetical order (for instance, a P clue could be an N or a T pentomino).

Answer String: Enter the letter associated with the pentomino occupying each cell in the two marked rows from left to right, separating the rows with a comma. Use CAPITAL LETTERS!

Time Standards (highlight to view): Grandmaster = 5:45, Master = 7:30, Expert = 15:00

    I’m very glad to see that the answer checker is back! I am catching up on some past puzzles. I have what I think is a proper solution, but is labelled as incorrect by the checker.

    Is this the valid solution?

    As suspected, I screwed up and violated the “A region may contain at most one letter clue” rule. Time to resolve! (I hope this didn’t post three times!)
