Pentominous by Grant Fikes
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: No P in this uzzle? (11 pentomino letter clues, but not P, appear in the starting grid)
Author/Opus: This is the 133rd 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 row from left to right and then the marked column from top to bottom, separating the groups with a comma. Use CAPITAL LETTERS!
Time Standards (highlight to view): Grandmaster = 2:40, Master = 5:00, Expert = 10:00
Solution: PDF; a solution video is available here.

“No P in this uzzle?”
Shouldn’t that be:
“No E in this PUZZL?” 😉

A very nice puzzle, thanks 🙂
I got stuck on the top left for so long……
I misunderstood the theme at first, and was trying to solve it without using the P-pentomino (unsuccessfully).
Same here.
Ahhhhh I retraced my steps three times to figure out where I made a mistake, then finally checked the comments to see if others were having the same problem.
Theme ≠ rules. Got it.
There is a playful question mark at the end, which I thought would be critical to understanding the difference between a theme and a rule here.
Of course, the last time when we titled the puzzle “Zero X” AND mentioned 11 pentominoes in the rules, that also failed for several test-solvers.
I don’t think there is a way to win them all with the pentominoes.
