LinkedIn Zip #451 Answer & Analysis

Begin with the lowest clues. The path starts at 1 in R6C2 and must eventually reach 2 at R3C3, then 3 at R4C4, then 4 at R5C5. Using the confirmed endBoardData, the clean route climbs from the lower middle into the center before turning back down through 3 and 4. This keeps the central cells connected without cutting the board into separate regions.

Once 4 is reached at R5C5, the path cannot linger in the lower-right area because 5 is above at R2C6 and 6 is later at R6C6. The verified route rises through the right-center column, touches 5, and then descends again to 6. This up-then-down shape is important because it uses the right half efficiently while keeping the top edge open for 7 and 8.

From 6 at R6C6, the path shifts to the far right, climbs to 7 at R1C7, and then sweeps across the top row to 8 at R1C1. There are no internal walls blocking this movement, but the numbered order makes the top sweep the natural solution. Reaching 8 before dropping down again also avoids leaving isolated cells in the first two rows.

After 8 at R1C1, the path goes down to 9 at R2C2 and then continues through the left and center-left cells. This is the section that balances the board: it fills the previously untouched left side while setting up the late approach to 10. In a practical solve, this is the moment to check that every unused area still has an entrance and an exit.

The ending is a clean bottom-side closure. After the left sweep, the path reaches 10 at R7C1, then travels right across the remaining open cells and finishes at 11 in R7C7. This closing section works because all earlier moves preserved a single continuous lane through the bottom-right cells. That gives today's Zip solution a tidy finish with no repeats and no missed cells.
