Rules: Standard Sudoku rules apply. The board has different colored lines on it. The two cells connected by the lines may be one of the following four cases: Sum is 5; Sum is 10; Difference is 1; Ratio is 1:2. Lines of the same color represent the same situation; lines of different colors are different and need to be inferred by the solver. Not all lines are given. Identical pairs are directly connected by only one color line (e.g. 2 and 3 are connected by a line with a difference of 1, they are not connected by a line with a sum of 5)
