Border Sum Pentominous
(Published on 24. March 2023, 21:05 by Gliperal)
Normal Pentominous rules apply: Divide the grid into pentominoes (orthogonally-connected regions of 5 cells), such that no two pentominoes of the same shape (including rotations and reflections) touch orthogonally.
Each pentomino has been assigned a unique number from 1-12. Clues outside of a row or column represent the borders that appear in that row or column, in the order they appear: the value of a clue is equal to the sum of the numbers assigned to the two pentomino shapes sharing that border.
A ? can represent any value.
Example:
Solution code: Row 5, Row 11: the corresponding number of the pentomino in each cell
