LinkedIn Zip #475 is a 8×8 Zip board with 16 numbered checkpoints and 12 walls. The Hamiltonian path visits all 64 cells once, hits checkpoints 1–16 in order, and ends on the final number. Segment plan: 1→2 (2 cells, R3C2→R3C3); 2→3 (3 cells, R3C3→R4C4); 3→4 (6 cells, R4C4→R2C3); 4→5 (2 cells, R2C3→R2C2); 5→6 (17 cells, R2C2→R7C3); 6→7 (3 cells, R7C3→R6C2); 7→8 (4 cells, R6C2→R5C4); 8→9 (11 cells, R5C4→R6C7); 9→10 (8 cells, R6C7→R2C6); 10→11 (3 cells, R2C6→R3C7); 11→12 (10 cells, R3C7→R4C5); 12→13 (2 cells, R4C5→R5C5); 13→14 (3 cells, R5C5→R6C6); 14→15 (2 cells, R6C6→R7C6); 15→16 (2 cells, R7C6→R7C7).
Board spotlight: Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint. Wall count 12 on 8×8 shapes which corridors stay open between numbered cells.
Segment 1 (1→2): 2 cells from R3C2 to R3C3. Tight 2-cell hop — checkpoints 1 and 2 sit near each other; still visit every intervening cell exactly once.
Segment 2 (2→3): 3 cells from R3C3 to R4C4. Tight 3-cell hop — checkpoints 2 and 3 sit near each other; still visit every intervening cell exactly once.
Segment 3 (3→4): 6 cells from R4C4 to R2C3. 6 cells link checkpoint 3 at R4C4 to checkpoint 4 at R2C3 with open corridors (no walls on this segment).
Segment 4 (4→5): 2 cells from R2C3 to R2C2. Tight 2-cell hop — checkpoints 4 and 5 sit near each other; still visit every intervening cell exactly once.
Segment 5 (5→6): 17 cells from R2C2 to R7C3. 17 cells link checkpoint 5 at R2C2 to checkpoint 6 at R7C3 with open corridors (no walls on this segment).
Segment 6 (6→7): 3 cells from R7C3 to R6C2. Tight 3-cell hop — checkpoints 6 and 7 sit near each other; still visit every intervening cell exactly once.
Segment 7 (7→8): 4 cells from R6C2 to R5C4. 4 cells link checkpoint 7 at R6C2 to checkpoint 8 at R5C4 with open corridors (no walls on this segment).
Segment 8 (8→9): 11 cells from R5C4 to R6C7. 11 cells link checkpoint 8 at R5C4 to checkpoint 9 at R6C7 with open corridors (no walls on this segment).
Segment 9 (9→10): 8 cells from R6C7 to R2C6. 8 cells link checkpoint 9 at R6C7 to checkpoint 10 at R2C6 with open corridors (no walls on this segment).
Segment 10 (10→11): 3 cells from R2C6 to R3C7. Tight 3-cell hop — checkpoints 10 and 11 sit near each other; still visit every intervening cell exactly once.
Segment 11 (11→12): 10 cells from R3C7 to R4C5. 10 cells link checkpoint 11 at R3C7 to checkpoint 12 at R4C5 with open corridors (no walls on this segment).
Segment 12 (12→13): 2 cells from R4C5 to R5C5. Tight 2-cell hop — checkpoints 12 and 13 sit near each other; still visit every intervening cell exactly once.
Segment 13 (13→14): 3 cells from R5C5 to R6C6. Tight 3-cell hop — checkpoints 13 and 14 sit near each other; still visit every intervening cell exactly once.
Segment 14 (14→15): 2 cells from R6C6 to R7C6. Tight 2-cell hop — checkpoints 14 and 15 sit near each other; still visit every intervening cell exactly once.
Segment 15 (15→16): 2 cells from R7C6 to R7C7. Tight 2-cell hop — checkpoints 15 and 16 sit near each other; still visit every intervening cell exactly once.
Complete path: 64 cells, checkpoints in order, ending on 16. Pattern: dense-wall maze — Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint.
