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 sixth 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!

Solving the previous and this one in succession was like solving the same puzzle twice. As I liked the previous one, so did I like this one, but I should have waited a few days. Thanks
Reply: yes, I understand a few puzzles similar, but I want to publish all human solvable sudokus I found in this concept. Thank you for solving and comments!
