Overview
LinkedIn Zip #472 is the LinkedIn Zip daily for July 2, 2026. Zip is LinkedIn's path puzzle: draw one continuous route through a 7×7 grid, visit every cell exactly once, hit 12 numbered checkpoints in order, and navigate around 6 walls. This page includes the live board, a solved-board view, and a step-by-step Solution walkthrough. Difficulty: Medium. Estimated solve time: 4–6 min.
Answer
This 7×7 Zip route visits all 49 cells once, hits 12 checkpoints in order, and respects 6 walls:
1→2 (7 cells, R1C5→R1C7); 2→3 (5 cells, R1C7→R5C7); 3→4 (4 cells, R5C7→R7C6); 4→5 (7 cells, R7C6→R3C6); 5→6 (4 cells, R3C6→R5C5); 6→7 (5 cells, R5C5→R3C3); 7→8 (7 cells, R3C3→R7C3); 8→9 (4 cells, R7C3→R5C2); 9→10 (7 cells, R5C2→R1C2); 10→11 (4 cells, R1C2→R3C1); 11→12 (5 cells, R3C1→R7C1)
Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.

Complete: Hamiltonian path covers all 49 cells, checkpoints 1–12 in order, ending on checkpoint 12 at R7C1.
Pattern
Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.

Segment chain 1→2 (7 cells), 2→3 (5 cells), 3→4 (4 cells), 4→5 (7 cells), 5→6 (4 cells), 6→7 (5 cells), 7→8 (7 cells), 8→9 (4 cells), 9→10 (7 cells), 10→11 (4 cells), 11→12 (5 cells) is the only wall-respecting order that visits all 49 cells.
Skipping a cell in any hop breaks the Hamiltonian rule immediately.
Checkpoint-cluster board — 7×7, 12 checkpoints, 6 walls.
Solution
This 7×7 board has 12 checkpoints (1@R1C5, 2@R1C7, 3@R5C7, 4@R7C6, 5@R3C6, 6@R5C5, 7@R3C3, 8@R7C3, 9@R5C2, 10@R1C2, 11@R3C1, 12@R7C1) and 6 walls. The solution path covers 49 cells in 11 checkpoint hops: 1→2 (7 cells, R1C5→R1C7); 2→3 (5 cells, R1C7→R5C7); 3→4 (4 cells, R5C7→R7C6); 4→5 (7 cells, R7C6→R3C6); 5→6 (4 cells, R3C6→R5C5); 6→7 (5 cells, R5C5→R3C3); 7→8 (7 cells, R3C3→R7C3); 8→9 (4 cells, R7C3→R5C2); 9→10 (7 cells, R5C2→R1C2); 10→11 (4 cells, R1C2→R3C1); 11→12 (5 cells, R3C1→R7C1). Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.
