LinkedIn Zip #455 Answer & Analysis

Start at 1 in R3C3 and move into the center. The solved route goes to R3C4, then down to 2 at R4C4. From there, the path turns left because 2 has walls on its right and bottom, which makes the center exit direction important.

From 2, the route works left and then up through the middle-left area before crossing the upper-middle cells. This keeps the board connected and avoids sealing off the top row too early.

After crossing the upper middle, the path drops down the right-center side and then sweeps left across the lower middle to reach 3 at R6C2. This is the key transition that prepares the bottom edge for the final long run.

From 3, the solved path runs across the bottom row to the far right, then climbs the right edge all the way to 4 at R1C6 and steps left to 5 at R1C5. This is forced by the remaining space: the right side must be used to avoid trapping the top row.

After 5, the top row must be cleared from right to left. The bottom walls on the upper-middle cells prevent dropping down from the middle of the top row, so the only safe completion is to travel left across the top and then descend the left edge to 6 in R6C1.
