Logic Masters Deutschland e.V.

You can find more Entropy sudokus as well as my other puzzles here

Rules:

Sudoku: Fill every row, column and 3x3 box with the digits 1-9.

Arrow: Digits on an arrow have to sum to the digit in the corresponding circle and may repeat if allowed by other rules.

Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.

Have fun solving!
