Logic Masters Deutschland e.V.

• Normal Sudoku rules apply
• Digits separated by a black kropki dot has a ratio of 1:2. Digits separated by a white kropki dot are consecutive.
• Digits in black or white circles outside the grid indicates the number of hidden black or white kropki dots in the row or column.
• Black and white kropki border clues are mutually exclusive, so a cell edge can only be used to satisfy one clue.
• Not all clues or dots are given.

Here is an example row illustrating the rules (dots added for clarification).
