Rules:

Normal sudoku rules apply.

Digits in light blue cells are low entropi. (1,2,3)

Digits in light green cells are middle entropi. (4,5,6)

Digits in light orange cells are high entropi. (7,8,9)

A digit in a grey circle is odd.

Digits separated by an X sum to 10. All X’s are given.

Cells separated by a knights move (in chess) cannot contain the same digit.

The positive and the negative diagonals must sum to either 33 or 42.

There is exactly one X-sum clue in the grid that is 41. Eg. There is a 41 clue positioned outside a row or column somewhere, and it gives the sum of the first X digits in that row or column, where X is the first digit in that row or column.
