Normal sudoku rules apply. Finkz and Phinx must both reach different cupcakes by finding a path through the maze. The paths must not visit any cell more than once, share cells, cross themselves or each other, or pass through any thick maze walls. As well as moving orthogonally, they may move diagonally if there's a 2x2 space in which to do so, but may never pass diagonally through a round wall-spot on the corner of a cell. If a blackcurrant sits between two digits, one is double the other. If a redcurrant sits between two digits, one is odd and the other is even. Entering a yellow teleport will cause a rat to be instantly transported to the other yellow teleport. The teleports have identical digits. The digit on a pink motion sensor indicates the number of cells that are visited (by either rat) within the (up to 9) cells immediately surrounding the sensor. The sensor itself is counted, if visited. In this experiment, for any row or column, the digits visited by Finkz must have the same sum as the digits visited by Phinx. This sum must be determined for each row and column.
