Normal sudoku rules apply. Divide the grid into 3 zones. Each zone consists of a single group of orthogonally connected cells. No 2x2 area may be entirely within one zone. The first zone is 'too hot'. Any cell in the hot zone has a value one greater than its digit. The second zone is 'too cold'. Any cell in the cold zone has a value one less than its digit. The third zone is 'just right'; this is the Goldilocks Zone. In this zone, a cell's value equals its digit, like normal. The 9 objects (bowls, chairs and beds) all contain different digits, but each object of the same type has the same value. Zone borders (NOT box borders) divide blue lines into segments, each of which has the same total (ie; the total being the sum of that segment’s VALUES.) The two ends of a blue line always lie in different zones.
