Logic Masters Deutschland e.V.

Normal sudoku rules do not apply. Place 4 of the digits 1-9 into each puzzle without repeating in each column/row/box. Digits used in one puzzle do not appear in the other.

Dots in the center of a cell represent a relationship between the digit in it's respective cell in the other grid (i.e. R4C2 in each puzzle share a German Whispers constraint with each other.)

German Whispers - Digits along a German Whispers line (or dot between puzzles) must have a difference of at least 5.

Kropki - Digits separated by a black dot share a 2:1 ratio. Digits separated by a white dot are consecutive digits.
