Hidden Killer Pentominous Sudoku
(Published on 8. August 2020, 22:10 by illuminatens)
Divide the grid into pentominoes (five-cell regions) so that no two pentominoes of the same shape (including rotations/reflections) share an edge.
Instead of given edges, two types of information are given in the puzzle:
- Pentominoes make up killer cages in the grid. The sum of the cage is always in the upper left corner of the cage/pentomino.
- Each given digit is in a unique pentomino; not every pentomino has a given digit in it.
Digits cannot repeat in killer cages.
Penpa
Solution code: 6th Row and 6th Column

This is a proper hidden gem. Loved the interactions, thank you. Building the pentominous was very cool!

A blast from the "past", strange that I forgot the condition of no two similar pentomenos may share an edge but didn't need it anyway

Lovely puzzle. Really liked how the different constraints worked together.

Sums are as high as possible in the cage/pentomino, then leftmost as possible in the cage/pentomino.

By "the upper left corner", do you mean the highest cell in the left column or the left-most cell in the top row? Example, if a cage looks like an L on its side with 4 cells in bottom row and 1 cell above the rightmost bottom cell, would the clue be in the single top cell or all the way to the left in the bottom row?
