Blackout Pentopia
(Published on 21. December 2025, 00:53 by KNT)
Blacken some cells in the grid such that all blackened cells form pentominos (orthogonally connected groups of exactly five cells). Pentominos may not touch, not even diagonally. No pentomino shape may be used more than once, including rotations and reflections.
If a cell containing one or more arrows is unshaded, the arrows indicate the directions of the nearest pentomino cells. If there is no arrow in a specific direction, then the nearest pentomino cell is farther away, or there may be no such cell in this direction at all.
If a cell with an arrow or arrows is blackened, the cell gives no information.

Very fresh, and I absolutely loved the ending. Thanks for making this (and for not breaking my back with a 6-star)!

Yikes, for an easier one that took me longer than expected but it was still a fun puzzle with some sweet pento logic x)
