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, cross themselves or each other, share cells, 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. BLACKCURRANTS: If two digits are joined by a blackcurrant, one is double the other. REDCURRANTS: If two digits are joined by a redcurrant, one is odd and the other is even. 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. TEST CONSTRAINT: In this experiment, for any path segment connecting two teleports, no other cells along the segment may equal either of the two teleport digits at its ends, or lie numerically between them. Eg: if a path segment joins two teleports with the digits 3 and 6, then the other digits along this path segment may not include a 3, 4, 5 or 6.
