Logic Masters Deutschland e.V.

• Normal Sudoku rules: Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
• Arrows:The digits along each arrow must sum to the digit in the circled cell. Digits may repeat along an arrow if permitted by other rules.
• Arrow Variant: The digits in the cells pointed to by an arrow tip must sum to the product of the digits on that arrow. If multiple arrows are connected to the same circle each arrow is viewed seperately. E.g. if r6c6 contains a 5, along the arrow pointing into box 1 are 2 and 3. 2*3=6, so r1c1, r2c2, r3c3 have to sum to 6 (they would be a 1-2-3-triple).
