Logic Masters Deutschland e.V.

Normal sudoku rules apply. Place the digits 1-9 once each in every row, column, and 3x3 box.

Killer: digits inside a caged region must not repeat and sum to the total shown in the corner.

German whispers: digits along a green line must differ from their neighbours by at least 5.

Kropki: digits separated by a black dot are in a 1:2 ratio (one digit is double the other).

Cells connected by an X sum to 10. Cells connected by a V sum to 5. Not all Xs and Vs are given.

Digits may not repeat along marked diagonals.

Solve in VariantDoku (iOS) or on SudokuPad.
