• Each region must be either strictly larger than all of its orthogonal neighbours or strictly smaller than all of its orthogonal neighbours.
• If the region is a 2-digit number, only fill the units digit for answer check.

REGION BORDER LOTS:
• There are purple lines with diamond symbols placed along them. The digit that is placed in a cell with a diamond will count the number of cells along that line that have region borders arranged in the same shape as the diamond's black edges (regardless of how that shape is oriented).
• The grid edge counts as a region border.
