Normal sudoku rules apply. Finkz and Phinx must both reach the 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. The paths must only converge at the cupcake cell. As well as moving orthogonally, Finkz and Phinx may move diagonally if there's a 2x2 space in which to do so, but they may never pass diagonally through a round wall-spot on the corner of a cell. Digits may not repeat within a cage. All cages have the same total, to be deduced. An electricity symbol indicates the cage's shock value. Cages with a shock value of 5 or higher may not be entered. Cages with a shock value lower than 5 are safe to enter. If a red X sits between two digits, they sum to 10. In this experiment, both paths must be a valid 'between line', ie: the highest and lowest digits on a path can be found at its ends (on the rat and the cupcake cell, in some order) and not anywhere else along that path.
