Normal sudoku rules apply.
On a blue line, the sum of the lowest and highest digit equals the sum of all other digits on the line. On a red line, the difference of the lowest and highest digit equals the sum of all other digits on the line. The lowest and highest digit on a line cannot repeat, but the other digits can.
For example, a blue line can have the digits 1 5 7 3, since 1+7=3+5. A red line can have the digits 3 3 1 7, since 7-1=3+3.
The gray line is either red or blue.
