Logic Masters Deutschland e.V.

• Normal Sudoku rules apply: Place the digits 1-9 once in every row, column and 3x3 box.

• Kropki: The white dots are between consecutive digits. Cells joined by a black dot house two digits, one of which is double the other. Not all dots are given.

• Between lines: Digits along a between line must be between the digits on the circled ends of the line.

• Fog of war: The grid is partially covered with fog. A correctly placed digit will clear its cell and might (or might not) clear some other cells. No guessing is required.

• XV: Digits separated by a V sum to 5. Digits separated by an X sum to 10. Not all XVs are given.
