Rules:

1) Place the digits 1-9 into the grid so that every digit occurs exactly once in every row, column, and indicated 3x3 box. (These are exactly the rules of a newspaper sudoku puzzle.) 2) The sum of the digits along each line that connects two circles is equal to the sum of the digits in the circles at the ends. For example, if the circles at the ends of a line contain a 2 and a 7, the digits along the line could be 2, 3, and 4. Note that it is acceptable to repeat the 2 from the circle along the line as long as it does not violate rule 1. Tommy Occhipinti
