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, cross themselves or each other, or pass through any thick maze walls. There is no space to move diagonally in this maze. If two digits are joined by a blackcurrant, one is double the other. A purple arrow always points to the smaller of the two digits it sits between, and may only be passed through in the direction it's pointing. In this experiment, any two digits visited adjacently along a path must be different parities (one is odd and the other is even), and also have a difference of at least 5.
