Logic Masters Deutschland e.V.

Double thanks to Raumplaner for introducing me to the ranked cages constraint and challenging me to set with the XVXV constraint.

Rules: Normal sudoku rules apply.

XVXV: Digits in cells connected by a V sum to 5 or 15. Digits in cells connected by an X sum to 10 or 15.

Ranked cages: Digits in cages cannot repeat and sum to the total of the cage. The totals of cages must be different from each other. The number in the top left corner of a cage (if given) indicates the rank of the corresponding cage total, when all cage totals are ordered in increasing order. For example, a cage with a 3 in the top left means there are exactly 2 cages with a lower total.
