Logic Masters Deutschland e.V.

Another in the theme of animals made into sudoku puzzles, similar to Manx Cat. I think this is slightly easier, I am pitching as 3 stars to begin with but wouldn't be surprised if it is lowered to 2. Good luck!

• Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box
• Diagonal: Digits may not repeat along either main diagonal, marked with a blue line
• Modular Line: Any run of three digits along a teal modular line must have a different remainder divided by 3, i.e. one from (1,4,7), one from (2,5,8), one from (3,6,9)
• Odd/Even: Digits in circles are odd. Digits in squares are even
• XV: Digits separated by a V sum to 5. Digits separated by an X sum to 10. No negative constraint
• Little Killer: Clues outside the grid give the sum of the digits along that diagonal
