LinkedIn Zip #470 Answer & Analysis

The board starts at 1 in the lower-right corner, so the first part of the path is forced upward along the right edge until it reaches 2. That opening keeps the rest of the grid available instead of cutting off the top rows.

After reaching 2, the route turns left across the top row and then drops through the upper-right and upper-middle corridor. The walls around the nearby cells force a zigzag, so the path cannot go straight down or straight across without breaking the grid coverage.

The middle of the board is where the numbered sequence becomes most constrained. The path must pass through 3, 4, 5, and 6 in order while respecting the wall pairs, which means a careful S-shaped route through the center and lower-middle cells.

Once the path reaches the left edge, it has to climb back upward through open cells to keep the board connected. This move is important because the later numbers 7, 8, and 9 sit in the upper-left/upper-middle zone, and the path must arrive there with enough freedom to continue.

The last section is a short but precise finish. The route passes 7, then 8, then 9, and finally ends on 10 in the lower part of the upper-left block. The path must not revisit any cell, so the final turns are fixed once the earlier corridor is set.
