Spectrum [Four Color Theorem Fillomino]
(Published on 30. May 2023, 16:31 by MicroStudy)
Rules
- Fillomino: Divide the grid into regions of orthogonally-connected cells such that no two regions of the same size share an edge. Enter a number into each cell equal to the size of its region.
- Four Color Theorem: Each region must be entirely in one color. There are a total of four different colors in the grid. Regions of the same color cannot touch orthogonally. Additionally, regions of the same color must be of different sizes.
- Arrows: Digits on arrows indicate the distance to the nearest cell of the same color in the indicated direction (Adjacent cells are a distance of 1 from each other). Not all arrows are necessarily given.

Really liked the ruleset, perhaps a sequel on a much larger grid? :)
