Rules:
Normal sudoku rules apply. Furthermore, there are two snakes (snake A and B) in the grid. One is an 'Equal Sum Line' Snake (see below) and the other is a 'German Whisper Line' Snake (again, see below). The solver must determine which is which. Each snake is an orthogonally connected set of cells (the starts and ends are marked) and each snake MUST visit every 3x3 box. The snakes cannot touch themselves, even diagonally. The snakes may touch each other but they do not cross each other. The outside clues give the sum of the NON-snake cells in that direction. The squares give the number of the NON-snake cells in that box. On an 'Equal Sum Line', digits have an equal sum N within each box the line passes through. On a German Whisper Line, adjacent digits must have a difference of at least 5.
