Logic Masters Deutschland e.V.

Normal Sudoku rules apply. The vertical yellow line in the middle of the grid divides our universe from the mirror universe. Each black/white set of Kropki dot clues mirrored across this line consists of one good twin, which strictly follows standard Kropki rules, and one evil twin, which strictly avoids them. Cage totals are unaffected by mirror logic. Kropki Pairs: Digits separated by a black dot are in a 2:1 ratio. Digits separated by a white dot are consecutive. Evil Kropki Pairs: Digits separated by a black dot are never in a 2:1 ratio. Digits separated by a white dot are never consecutive. Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage.
