LinkedIn Zip #466 Answer & Analysis

The path begins at 1 on R6C4. From there, the route is forced down and around the lower-right corner before climbing the right side and reaching 2 at R1C5. This opening sweep helps avoid trapping the top row too early.

After 2 at R1C5, the path must continue through the upper-middle and down the right-center side until it reaches 3 at R6C6. This is a controlled descent that preserves the remaining open cells.

From 3, the path turns left and then folds back upward and across the upper-middle to hit 4, 5, and 6 in order. The wall on the 6 cell matters because it blocks a direct downward shortcut, so the route must approach 6 from the side or above instead.

Once 6 is reached, the path cannot drop through the wall under it, so it must turn upward and then travel across the top-left side before sweeping down the left edge. This creates the long backtrack needed to reach 7 cleanly.

The final stretch threads back into the middle of the board, hits 8, and ends at 9 in the upper-left area. This last section confirms that every cell has been used exactly once and that the numbered order is preserved.
