Logic Masters Deutschland e.V.

• Normal 6x6 Sudoku rules apply.
• Kropki Dots: Digits separated by a white dot are consecutive. Digits separated by a black dot have a 1:2 ratio, meaning one is exactly double the other. Not all dots are necessarily given.
• Clones: Some cells are surrounded by dotted lines, called "cages." Cages which are marked with the same letter contain exactly the same digits in the same relative positions. Digits are allowed to repeat within the cages as normally allowed by other rules. Important note: the clone is rotated 180 degrees from the original.
