Logic Masters Deutschland e.V.

Normal Sudoku rules apply. Blue lines/cages/arrows: Fibonacci constraint. Orange lines/cages/arrows: Prime constraint. Cages: The total sum of the cage is a prime (orange) or Fibonacci (blue) number. Counting arrows: The bulb digit equals the number of Prime/Fibonacci digits on its arrow (matching the arrow’s color), including the bulb itself. Lines: Each adjacent pair of digits on a line must sum to a prime (orange) or Fibonacci (blue) number. The box 2 and box 7 are clones. https://sudokupad.app/xgltfvrzqy
