Case file LinkedIn Patches #137: 7×7 tiling puzzle, 14 clue exhibits, area range 2–5 cells per patch. Full partition: 14 rectangles tile the 7×7 grid (49 cells): clue 1 → 1×2, clue 2 → 1×4, clue 3 → 1×4, clue 4 → 3×1, clue 5 → 1×4, clue 6 → 2×2, clue 7 → 1×5, clue 8 → 1×2, clue 9 → 1×2, clue 10 → 1×4, clue 11 → 1×4, clue 12 → 3×1, clue 13 → 1×4, clue 14 → 2×2. No overlap, every clue covered exactly once. Pattern tag: grid-partition puzzle.
Board spotlight: Clues are spread across the grid with mixed constraints — work from the tightest clues outward and verify each patch still allows a full tiling. With 7 of 14 clues showing a numbered area, dimension math often pins down rectangle size before you choose a position on the grid.
General Patches strategy on 7×7: 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, 1×2 at Row 1, column 1. The clue shows area 2, so its patch must cover exactly 2 cells (1×2 = 2). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 2: clue 2, 1×4 at Row 1, column 3. The clue shows area 4, so its patch must cover exactly 4 cells (1×4 = 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, 1×4 at Row 2, column 1. The clue shows area 4, so its patch must cover exactly 4 cells (1×4 = 4). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Exhibit 4: clue 4, 3×1 at Row 1, column 7. The shape icon allows any rectangle proportion. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 5: clue 5, 1×4 at Row 3, column 1. The shape icon allows any rectangle proportion. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 6: clue 6, 2×2 at Row 2, column 5. The shape icon requires a square. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 7: clue 7, 1×5 at Row 4, column 1. The shape icon allows any rectangle proportion. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 8: clue 8, 1×2 at Row 4, column 6. The clue shows area 2, so its patch must cover exactly 2 cells (1×2 = 2). The shape icon requires a wide rectangle (wider than tall). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Exhibit 9: clue 9, 1×2 at Row 5, column 1. The clue shows area 2, so its patch must cover exactly 2 cells (1×2 = 2). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 10: clue 10, 1×4 at Row 5, column 3. The clue shows area 4, so its patch must cover exactly 4 cells (1×4 = 4). Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 11: clue 11, 1×4 at Row 6, column 1. The clue shows area 4, so its patch must cover exactly 4 cells (1×4 = 4). This is the only rectangle that fits the clue, avoids other patches, and still allows a full tiling.
Exhibit 12: clue 12, 3×1 at Row 5, column 7. The shape icon allows any rectangle proportion. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 13: clue 13, 1×4 at Row 7, column 1. The shape icon allows any rectangle proportion. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Exhibit 14: clue 14, 2×2 at Row 6, column 5. The shape icon requires a square. Several rectangles fit this clue on their own, but only this one still allows the whole grid to be tiled.
Verdict: tiling set is consistent with every clue constraint. Case closed.
