Overview
LinkedIn Zip #487 is the LinkedIn Zip daily for July 17, 2026. Zip is LinkedIn's path puzzle: draw one continuous route through a 8×8 grid, visit every cell exactly once, hit 16 numbered checkpoints in order, and navigate around 0 walls. This page includes the live board, a solved-board view, and a step-by-step Solution walkthrough. Difficulty: Hard. Estimated solve time: 6–10 min.
Answer
This 8×8 Zip route visits all 64 cells once, hits 16 checkpoints in order, and respects 0 walls:
1→2 (4 cells, R5C6→R3C5); 2→3 (6 cells, R3C5→R6C7); 3→4 (4 cells, R6C7→R7C5); 4→5 (9 cells, R7C5→R5C7); 5→6 (2 cells, R5C7→R4C7); 6→7 (10 cells, R4C7→R2C6); 7→8 (2 cells, R2C6→R2C5); 8→9 (17 cells, R2C5→R7C4); 9→10 (2 cells, R7C4→R7C3); 10→11 (4 cells, R7C3→R5C2); 11→12 (2 cells, R5C2→R4C2); 12→13 (2 cells, R4C2→R4C3); 13→14 (4 cells, R4C3→R6C4); 14→15 (6 cells, R6C4→R3C2); 15→16 (4 cells, R3C2→R2C4)
Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.

Pattern
Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.
