Entropic Filter by Cygne

Rules

  • Normal Sudoku rules apply.
  • Global Entropy: Every 2x2 area in the grid contains at least one low digit (1,2,3), at least one medium digit (4,5,6) and at least one high digit (7,8,9).
  • German Whispers: Adjacent digits along a green line must differ by at least 5.
  • V-Sums: Digits separated by a V sum to 5.

I am still obsessed with interactions between Entropy and Whispers, but this time I decided to use global Entropy rather than Entropy lines, and was able to achieve a much sparser grid than my usual. If you enjoyed this one, please consider trying out these prior ones with this theme:
