Blobs' Borders 2 (Posted on 2019-04-10) Difficulty: 3 of 5
As in the first Blob's Borders:

Divide the below grid into ten areas (blobs) so that each area:

  • ... is contiguous (all cells connect via edges, not just vertices).
  • ... has exactly one of the ten numbers shown in the grid.
  • ... contains as many cells as the number that it contains.
  • ... borders (along edges, not vertices) the same number of other areas as the number that it contains; for example, a 6-cell area will border six other areas, again based on the digit 6 that is contained within its bounds.

Thanks much for the useful tips, Charlie. I have often wondered how to get columns to align.
