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, or pass through any thick maze walls. HOT AND COLD ZONES: Divide the grid into two zones of orthogonally connected cells, one hot and the other cold. No 2x2 area may be completely in one zone. INVISIBLE WALLS: A few maze walls are visible, but the rest are invisible and must be located. If two orthogonally adjacent cells are in different zones, a wall exists between them. If they are in the same zone, no wall exists between them. Because no 2x2 spaces exist fully within one zone, no diagonal movements are possible in this maze. BOX BALANCE: • The value of a hot cell equals its digit +1. • The value of a cold cell equals its digit -1. • In each 3x3 box, the total value of hot cells must equal the total value of cold cells. CURRANTS: • If a BLACKCURRANT sits between two cells, then the value of one is double the value of the other. • If a REDCURRANT sits between two cells, then one has an odd value and the other has an even value. • Two cells joined by a currant are both in the same zone. TEST CONSTRAINT: In this experiment, Phinx must stay in the hot zone and Finkz must stay in the cold zone.
