Rules
Divide the grid into regions using cardinal and ordinal edges.
- Each region contains exactly one numbered cell, which indicates the region's side count.
- Regions must be simple polygons (no holes, no self-intersection).
- Edges must not intersect numbered cells.
- Edge paths must not travel straight through junctions.
Example
A demonstration of the fourth rule: an intersection cannot contain two edges facing the same direction.
