Case file LinkedIn Patches #117: 8×8 tiling puzzle, 10 clue exhibits, area range 4–12 cells per patch. Full partition: 10 rectangles tile the 8×8 grid (64 cells): clue 1 → 2×3, clue 2 → 4×1, clue 3 → 4×3, clue 4 → 4×1, clue 5 → 2×3, clue 6 → 1×4, clue 7 → 3×2, clue 8 → 4×2, clue 9 → 2×4, clue 10 → 1×6. No overlap, every clue covered exactly once. Pattern tag: area-forced layout.
Board spotlight: Many clues show a numbered area — when area and shape combine, the rectangle size is often mathematically fixed before placement. With 8 of 10 clues showing a numbered area, dimension math often pins down rectangle size before you choose a position on the grid.
General Patches strategy on 8×8: rectangles cannot overlap, every cell must belong to exactly one patch, and each patch must contain precisely one clue at its anchor cell. When a clue shows area 12 and a tall icon, only a few height×width pairs are legal — list them before drawing. After each placement, mentally partition the leftover white space: if any region cannot host its remaining clues, back up and try the next candidate.
Exhibit 1: clue 1, 2×3 at Row 1, column 2. The clue shows area 6, so its patch must cover exactly 6 cells (2×3 = 6). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 2: clue 2, 4×1 at Row 1, column 1. The clue shows area 4, so its patch must cover exactly 4 cells (4×1 = 4). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 3: clue 3, 4×3 at Row 1, column 6. The clue shows area 12, so its patch must cover exactly 12 cells (4×3 = 12). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Exhibit 4: clue 4, 4×1 at Row 1, column 5. The clue shows area 4, so its patch must cover exactly 4 cells (4×1 = 4). The shape icon requires a tall rectangle (taller than wide). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 5: clue 5, 2×3 at Row 3, column 2. The shape icon requires a wide rectangle (wider than tall). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 6: clue 6, 1×4 at Row 5, column 5. The shape icon requires a wide rectangle (wider than tall). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 7: clue 7, 3×2 at Row 5, column 3. The clue shows area 6, so its patch must cover exactly 6 cells (3×2 = 6). The shape icon requires a tall rectangle (taller than wide). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 8: clue 8, 4×2 at Row 5, column 1. The clue shows area 8, so its patch must cover exactly 8 cells (4×2 = 8). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Exhibit 9: clue 9, 2×4 at Row 6, column 5. The clue shows area 8, so its patch must cover exactly 8 cells (2×4 = 8). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Exhibit 10: clue 10, 1×6 at Row 8, column 3. The clue shows area 6, so its patch must cover exactly 6 cells (1×6 = 6). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Verdict: tiling set is consistent with every clue constraint. Case closed.
