Logic Masters Deutschland e.V.

• Extra regions: The 4 additional marked regions are sudoku boxes.
• Normal Sudoku: Place the digits 1-9 once each in each row, column, and box (including marked regions).
• Kropki: Digits separated by a black dot have a 1 to 2 ratio. Digits separated by a white dot are sequential. Not all dots are given; however, all dots on the border of an extra region have been given.
• Note: There is nothing preventing a black dot from also being sequential or a white dot from also being in a 1 to 2 ratio.
• Examples: R5C1 and R5C2 can neither be sequential or in a 1 to 2 ratio. R7C1 and R7C2 could still be a 1 2 pair.
