LinkedIn Zip #470 is a 7×7 Zip board with 10 numbered checkpoints and 12 walls. The Hamiltonian path visits all 49 cells once, hits checkpoints 1–10 in order, and ends on the final number. Segment plan: 1→2 (7 cells, R7C7→R1C7); 2→3 (20 cells, R1C7→R4C3); 3→4 (2 cells, R4C3→R5C3); 4→5 (3 cells, R5C3→R6C2); 5→6 (2 cells, R6C2→R6C3); 6→7 (16 cells, R6C3→R3C3); 7→8 (2 cells, R3C3→R2C3); 8→9 (2 cells, R2C3→R2C2); 9→10 (3 cells, R2C2→R4C2).
Board spotlight: Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint. Wall count 12 on 7×7 shapes which corridors stay open between numbered cells.
Segment 1 (1→2): 7 cells from R7C7 to R1C7. 7 cells link checkpoint 1 at R7C7 to checkpoint 2 at R1C7 with open corridors (no walls on this segment).
Segment 2 (2→3): 20 cells from R1C7 to R4C3. Long 20-cell sweep (41% of the board) from checkpoint 2 to 3 — most of the Hamiltonian path lives in this detour.
Segment 3 (3→4): 2 cells from R4C3 to R5C3. Tight 2-cell hop — checkpoints 3 and 4 sit near each other; still visit every intervening cell exactly once.
Segment 4 (4→5): 3 cells from R5C3 to R6C2. Tight 3-cell hop — checkpoints 4 and 5 sit near each other; still visit every intervening cell exactly once.
Segment 5 (5→6): 2 cells from R6C2 to R6C3. Tight 2-cell hop — checkpoints 5 and 6 sit near each other; still visit every intervening cell exactly once.
Segment 6 (6→7): 16 cells from R6C3 to R3C3. 16 cells link checkpoint 6 at R6C3 to checkpoint 7 at R3C3 with open corridors (no walls on this segment).
Segment 7 (7→8): 2 cells from R3C3 to R2C3. Tight 2-cell hop — checkpoints 7 and 8 sit near each other; still visit every intervening cell exactly once.
Segment 8 (8→9): 2 cells from R2C3 to R2C2. Tight 2-cell hop — checkpoints 8 and 9 sit near each other; still visit every intervening cell exactly once.
Segment 9 (9→10): 3 cells from R2C2 to R4C2. Tight 3-cell hop — checkpoints 9 and 10 sit near each other; still visit every intervening cell exactly once.
Complete path: 49 cells, checkpoints in order, ending on 10. Pattern: dense-wall maze — Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint.
