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.

Once in "View Source" mode, you could try copying and pasting the table text (view this from appropriate setting in your browser) into the comment, and add colors, as in the following table taken from the sample portion of the original puzzle (hopefully it works for non-scholars as well):




***** Well, that did not work, even at scholar level *******

But the Formatting>> pre-formatted should work, with the letter system you used.
