Logic Masters Deutschland e.V.

Puzzle Rules:

• Normal Sudoku rules apply.
• Even/odd: Cells with gray squares/circles must contain even/odd digits.
• Kropki pairs: A black dot indicates that two cells are in a 1:2 ratio. Not all black dots are given.
• Modified killer: Digits in cages sum to the number in the top left corner. The letters A-F correspond to some numbers that need to be determined. Cages with the same sum must contain the same set of digits.
