Normal sudoku rules apply. Each 2x2 box in a grid has contain low digit {1,2,3}, middle digit {4,5,6} and high digit {7,8,9}.
This is the ninth sudoku in the Entropy Miracles series. You can find the others in my profile. All of them use the Entropy rule and have only six starting digits, with no additional clues or constraints. Enjoy solving!
Solution code: Row 9 (9 digits)
