Normal sudoku rules apply. AIM OF EXPERIMENT: Finkz the rat must reach the cupcake by finding a path through the maze. The path must not visit any cell more than once, cross itself, or pass through any thick walls. (The walls have been decorated with red tinsel.) As well as moving orthogonally, Finkz may move diagonally if there's a 2x2 space in which to do so. DYNAMIC FOG: Entering correct digits may clear fog somewhere in the maze. CHRISTMAS LIGHTS: An orange Christmas light indicates that any digits visited by Finkz in its row or column are odd. A blue Christmas light indicates that any digits visited in its row or column are even. TELEPORTS: Every teleport is part of a matching pair. Entering a teleport will cause Finkz to be instantly transported to the matching coloured teleport. From there she can continue her journey. Matching teleports always have identical digits, but teleports that don't match always have different digits. BLACKCURRANTS: Blackcurrants sit between two digits with a 1:2 ratio. BAUBLES: The number on a gold bauble gives the total of any cells it touches. TEST CONSTRAINT: In this experiment, any two cells that are adjacent along the path contain consecutive digits (except when separated by teleportation, where the digits are identical.)
