Logic Masters Deutschland e.V.

• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Orange lines are both Lockout Lines and Dutch Whispers.
• As Lockout Lines: Individual Lockout Lines are shown as a line with diamond endpoints. Digits in directly connected endpoints must differ by 4 or more. Digits along lines must fall outside the range defined by their diamonds. Line digits may repeat if allowed by other rules. A diamond may be shared by multiple Lockout Lines, but each segment is treated as a different line.
• As Dutch Whispers: Neighboring digits along a line must differ by at least 4. Diamonds are considered part of the Dutch Whisper lines.
