Patches #59 Solving Notes
First read: Patches #59 starts with 12 clue cells on an 8×8 board. Begin with the fixed clues at r2 c2, r2 c3, r3 c2 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 best anchor is the square clue at r3 c2, not a random corner. This clue is useful because a strict shape has less room to wiggle than an open patch. After reveal, check it against Region 5, which should form the 2×2 square block from r3 c1 to r4 c2.
