Logic Masters Deutschland e.V.

Rules:

Normal Sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box.

Killers cages: Digits within a cage must not repeat and must sum to the number given in the left top corner.

Diagonal: The marked diagonal must contain the same 3 digits within each box.

Odd/Even: Cells containing a grey circle are odd, cells containing a grey square are even.

(Sudokupad won't give a correct solution due to the marked diagonal having reapeted digits, sorry about that)
