LinkedIn Patches #68 Answer & Analysis

The far-left 4-cell patch is forced into a vertical strip, because the left border gives it no room to spread sideways. Right beside it, the upper-left 4-cell patch fits as a compact 2-by-2 block, using the only space that keeps it connected and away from the border strip.

The top-right 4-cell patch is constrained to the top row, while the next 4-cell patch sits directly beneath it in the second row. These two pieces act like a roof over the upper-right side and are easy to confirm once the left side is anchored.

The center-left column is forced into a long 6-cell vertical patch, because it is boxed in above and below by smaller regions. On the right-middle side, the 6-cell patch must form a clean rectangle so it does not trap the small 2-cell patch beside it.

The red 3-cell region drops straight down in the second column, and the teal 4-cell region fills the lower-left edge. The pink 4-cell region beside the center column is also fixed by the surrounding boundaries, so it becomes a vertical strip in the lower half.

The tiny 2-cell patch on the right edge is forced into a short vertical stack, and the 3-cell patch in the lower-left middle becomes another straight column. These smaller pieces are important because they prevent the larger regions from over-expanding.
