Patches #110 Full Analysis
First read: Patches #110 starts with 9 clue cells on a 7×7 board. Begin with the fixed clues at r1 c2, r1 c7, r2 c3 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 5-cell clue at r1 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 2, which should form the 5-cell horizontal strip from r1 c2 to r1 c6.
