Puzzle #45 – Checkered Fillomino

This is an interesting variant that I saw in a few places, including GM Puzzles and the 24HPC. I feel like there’s a lot that I can do with this type.

P.S. New WordPress editor is trash. It doesn’t let you copy a post like the old one. Good thing the old editor is still available via some arcane URL.

Rules:
Standard Fillomino rules. Additionally, it must be possible to shade some regions so that no two regions of the same colour are adjacent to each other.
