This is the twelfth 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.

This puzzle is quite similar to numbers 10 and 11 — not only in appearance, but also in the solving process. If you do not enjoy that kind of similarity, you may want to skip this one.

Enjoy solving!
