Patches #75 Solving Notes
First read: Patches #75 starts with 11 clue cells on an 8×8 board. Begin with the fixed clues at r1 c1, r1 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 10-cell clue at r5 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 11, which should form the 5×2 rectangle from r1 c7 to r5 c8.
