Patches #92 Full Analysis
First read: Patches #92 starts with 4 clue cells on a 6×6 board. Begin with the fixed clues at r2 c2, r3 c3, r4 c4 instead of guessing color groups from empty space. Those clue cells are the safest anchors because every solved region must keep exactly one clue area and still cover the whole board.
Main anchor: The strongest number anchor is the 12-cell clue at r2 c2. Large regions usually have fewer safe placements, so this clue is a better first test than a tiny patch. After reveal, check it against Region 1, which should form the 2×6 rectangle from r1 c1 to r2 c6.
