SCHRODINGER CELLS: Fill each row, column and box with the digits 0-9 once each. To make this possible, each row, column and box contains one Schrödinger cell, which contains two digits. The value of a Schrödinger cell is equal to the sum of its two digits. 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 maze walls. As well as moving orthogonally, Finkz 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: Two values separated by a blackcurrant have a 1:2 ratio. ONE-WAY DOORS: Finkz may only pass directly through a purple arrow in the direction it is pointing. A purple arrow always points to the smaller of the two values it sits between. TEST CONSTRAINT: In this experiment, dotted box borders divide the correct path into segments that each contain at least 2 cells. The values of two adjacent cells within the same segment always have the same difference, and this difference is unique for every segment. Eg: if a segment has a sequence of values 1, 3, 5, 7, then its 'same difference' is 2, and so no other segment may have a 'same difference' of 2.
