(Published on 12. November 2024, 18:06 by sudoku_explorer)
- Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
- Global Entropy: Every 2x2 square of cells must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
- Quadruples: Every digit in a circle has to be assigned to one of the surrounding cells.
Solution code: Row 5 (9 digits, no spaces)

My first time doing Global Entropy, so there's probably some trick I missed, but I enjoyed working through it!

Very nice puzzle! I often struggle with the global entropy constraint, but here, especially in combination with the quads, it was quite approachable and fun. Thank you for setting and sharing, sudoku_explorer!
