Patches #42 was the 8×8 hard board of Saturday, November 7, 2026: 12 clues (2 squares, 5 talls, 1 wide and 4 any-shape), 4 of them with an area number, and 12 rectangles to draw so that every cell is covered exactly once. The patches run from 1 to 15 cells. Our deduction solver, the one behind the hint button, lays them all without guessing in 12 steps: 7 because only one rectangle fits a clue, 5 because some uncovered cell can be reached by only one clue. The tightest clue at the start is the tall 15 at row 4, column 7, with only 1 possible rectangle before anything is placed. A brute-force solver would face 62 branch points on the way to the unique answer.

How to start Patches #42: the first 10 patches

Each placement is what the hint button would say at that point, from the empty board. Rows and columns are counted from the top-left corner.

  1. Tall 15 clue at row 4, column 7 → 3×5 patch. Only one patch fits the tall rectangle (15) clue here: 3 wide × 5 tall. Every other rectangle would cross another clue, a placed patch or the edge.

  2. Tall clue at row 8, column 4 → 1×2 patch. Only one patch fits the tall rectangle clue here: 1 wide × 2 tall. Every other rectangle would cross another clue, a placed patch or the edge.

  3. Tall 3 clue at row 6, column 4 → 1×3 patch. Only one patch fits the tall rectangle (3) clue here: 1 wide × 3 tall. Every other rectangle would cross another clue, a placed patch or the edge.

  4. Wide clue at row 8, column 2 → 2×1 patch. Only one patch fits the wide rectangle clue here: 2 wide × 1 tall. Every other rectangle would cross another clue, a placed patch or the edge.

  5. Square clue at row 8, column 3 → 1×1 patch. Only one patch fits the square clue here: 1×1. Every other rectangle would cross another clue, a placed patch or the edge.

  6. Any shape clue at row 2, column 3 → 4×3 patch. The outlined cell can only be reached by the any-shape clue — no other clue's patch can stretch to it — so it belongs to that patch. (Fill it in draws the whole patch: 4 wide × 3 tall.)

  7. Any shape clue at row 2, column 6 → 4×2 patch. The outlined cell can only be reached by the any-shape clue — no other clue's patch can stretch to it — so it belongs to that patch. (Fill it in draws the whole patch: 4 wide × 2 tall.)

  8. Tall 3 clue at row 3, column 5 → 1×3 patch. Only one patch fits the tall rectangle (3) clue here: 1 wide × 3 tall. Every other rectangle would cross another clue, a placed patch or the edge.

  9. Tall 3 clue at row 7, column 5 → 1×3 patch. Only one patch fits the tall rectangle (3) clue here: 1 wide × 3 tall. Every other rectangle would cross another clue, a placed patch or the edge.

  10. Square clue at row 5, column 3 → 3×3 patch. The outlined cell can only be reached by the square clue — no other clue's patch can stretch to it — so it belongs to that patch. (Fill it in draws the whole patch: 3×3.)

2 more placements finish the board.
