Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply.

Magic Squares cages: Digits in each row, each column, and both main diagonals of a cage must sum to the same value in the top left corner. Digits may repeat inside Magic Square cage if allowed by other rules. The colours of the cages are for easier distinction and don't affect solution.

Arrows: Digits along an arrow must sum to the digit in the attached circle.

Dutch whispers: Two cells connected by a Dutch whisper (orange) line must have a difference of at least 4.

Parity lines: Every pair of consecutive cells along a parity (red) line must contain an even and odd digit.
