Patches #200 Full Analysis
First read: Patches #200 starts with 12 clue cells on an 8×8 board. Begin with the fixed clues at r1 c7, r2 c6, r3 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 8-cell clue at r4 c8. 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 8-cell vertical strip from r1 c8 to r8 c8.
