Entropy miracle 4
(Published on 9. February 2026, 11:49 by fractalminding)
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 fourth 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 1 (9 digits)

Super fun puzzle. The minimal layout was so elegant.

This definitely was a ramp-up in difficulty, seemingly straightforward at first. Usually it's the global entropy scanning that gets me, but this time, resolving the last parts was quite challenging. Great puzzle!

Cool and fun coloring puzzle, it got slightly trickier near the end with the tuples and stuff but I eventually passed through it. Nice discovery overall :)

Thank you! Yes, it gets a little difficult towards the end. But I like this sudoku, and I'm glad you do too.
