Pentominous

(Published on 11. August 2026, 11:56 by Lizzy01)

Rules:
Divide the grid into pentominoes (groups of 5 orthogonally connected cells) such that no two orthogonally touching pentominoes are the same shape (rotations and reflections count as the same shape)

Try it here.

If you like pentominous, you might also like to try polyominous.

Solution code: For each of the first 4 rows, the number of different shapes of pentomino present in that row (i.e if there are multiple of the same shape of pentomino you only count one of them) (4 digits)
