Peak Entropy
(Published on 28. April 2026, 14:00 by protheph)
Rules:
- Normal Sudoku Rules Apply: Fill every row, column, and 3x3 box with the digits 1-9 without repetition.
- Global Entropy: Every 2x2 area in the grid must contain at least one low digit {1,2,3}, one middle digit {4,5,6}, and one high digit {7,8,9}.
- High Ground: Every shaded cell must contain a digit strictly greater than any orthogonally adjacent unshaded cell.
Have fun!

Nice puzzle. The way the "High Ground" is shaded made it kinda hard to do cell coloring based on entropy.
