LinkedIn Zip #468 Answer & Analysis

The path must begin at the 1 in R2C4. From there, the clean opening is to move up into the top row and sweep left so the upper-left corner stays available for later. That gives the route a safe starting framework.

From the left edge, the route continues straight down and then runs across row 5. This is where 2 and 3 are collected in order, and it creates the long backbone that the rest of the puzzle can attach to.

Next, the path climbs through the central cells to 4 and 5, then continues through 6 and toward the upper-right side. This zigzag is important because it keeps the middle of the grid connected without forcing a revisit.

After 7, the route drops into the bottom-right corner, sweeps across the bottom row, and comes back up through row 6. This long loop is what makes room for 8, 9, and 10 while still leaving a path to the final numbers.

The final stretch turns back toward the right side, passes 11, and ends on 12. If every cell has been used exactly once and the numbered cells appear in order, the solution is complete.
