Logic Masters Deutschland e.V.

The Rules:

1. Normal sudoku rules apply. In each grid fill each row, column, and region with the six of the digits from 0 to 9 once each:
   • In the Northwast grid, use 0-5
   • In the Northeast grid, use 1-6
   • In the Southeast grid, use 2-7
   • In the Southwest grid, use 3-8
   • In the central grid, you must determine which of the 6 digits are required.
2. [Product Sum Arrows] The bulbs of the arrows contain a one or two digit number (reading from left to right) indicating the product of the sums of the digits along each arrow. Two digit numbers cannot start with 0. E.g. if one arrow contains a 2 + 3 and the other arrow contains a 3 + 1 + 5 then the circled value would be (2+3)x(3+1+5) = 5x9 = 45.
