This is my 10th puzzle with the Entropy constraint and the second in the Entropy Specials series.
In this series I combine the Entropy constraint with other new variants that also use the grouping into low (1,2,3), middle (4,5,6) and high (7,8,9) digits.

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.

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.

Team Spirit: Based on the grouping (i.e. {123}, {456}, {789}) each cell in the grid is assigned a Team Spirit score.
A cell gains 1 point for the digit in the cell itself, 2 points for each diagonally adjacent digit of the same group and 3 points for each orthogonally adjacent digit of the same group. The sum of the points a cell gains this way is the Team Spirit score.
If the digit in a cell equals the Team Spirit score of that cell the cell is marked with a diamond. All possible diamonds are given.

Have fun solving!
