Logic Masters Deutschland e.V.

• Normal Sudoku rules: Place the digits 1-9 in each row, column and box, without repeats.
• Arrows: Digits on an arrow sum to the digit in that arrows circle. If multiple arrows start from the same circle each individual arrow has to have that sum. Digits may repeat on an arrow, if allowed 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 r5c6 contains a 9, along the arrow pointing into box 8 are 2 and 7. 2*7=14, so r8c5 and r9c4 have to sum to 14 (they would be 6-8, 5-9 or 7-7).
