Logic Masters Deutschland e.V.

The Rules:

• Standard: Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or 3x3 region.
• Killer Cages: Digits in each cage sum to the clue in its top-left corner and cannot repeat.
• Kropki: White dots indicate that digits in adjacent cells are consecutive. Black dots indicate that digits in adjacent cells have a ratio of 2:1.
• Parity: Gray circles indicate that the digit in that cell must be odd.
• Factor Line: Adjacent digits along a purple line must have a multiplicative factor in common. The common factor is only allowed to be 1 if one of the digits is 1. Example: 4 could only be next to 1, 2, 4, 6, or 8.

For your convenience, the chart below shows a full representation of what digits are allowed to be adjacent on a factor line. If a cell is green, the digits in that row/column are allowed to be adjacent.
