Logic Masters Deutschland e.V.

Rules:

Normal Sudoku Rules apply.

Killer Cage rules apply, but with some modifications. Each cage must expand into an orthogonally adjacent cell to form a pentomino. The cage total (number in corner) gives the sum of all cells in that pentomino. Pentominoes do not contain repeated digits, do not overlap or share cells, and no two pentominoes may be the same shape, including rotations and reflections.

XV rules apply. Digits separated by an X sum to 10, and digits separated by a V sum to 5. All possible Xs and Vs have been given (negative constraint applies).
