RAT RUN 28: Hypothesis

Normal sudoku rules apply.

AIM OF EXPERIMENT: 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.

TELEPORTS: Entering a teleport will cause a rat to be instantly transported to the matching coloured teleport. Matching teleports always have identical digits, but teleports that don't match always have different digits.

ONE-WAY DOORS: A purple arrow may only be passed through in the direction the arrow is pointing. An arrow always points to the smaller of the two digits it sits between.

GRAPES: A green grape sits between two digits with a difference of at least 5.

TEST CONSTRAINT: In this experiment, Finkz may only visit even digits, and Phinx may only visit odd digits. You must determine which rat is which.
