Logic Masters Deutschland e.V.

The Rules:

• Normal Sudoku rules apply.
• The numbers on the 'arrows' sum to the circled cells on one side, and multiply to the circled cells on the other side. You must determine which is which.
  • Examples:
    • e.g. (14)-2-7-(9)
    • e.g. (42)-6-7-(13)
  • It's possible that a circled cell may be a sum for one arrow and a product for a different arrow.
  • Numbers may repeat along an arrow if sudoku rules allow.
