Case file LinkedIn Zip #467: 8×8 path puzzle, 8 checkpoint exhibits, 28 blocked edges. Full trace covers 64 cells. Hop summary: 1→2 (21 cells, R7C7→R5C7); 2→3 (2 cells, R5C7→R6C7); 3→4 (3 cells, R6C7→R5C6); 4→5 (12 cells, R5C6→R2C2); 5→6 (14 cells, R2C2→R3C2); 6→7 (4 cells, R3C2→R4C2); 7→8 (14 cells, R4C2→R4C3).
Board spotlight: Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint. Wall count 28 on 8×8 shapes which corridors stay open between numbered cells.
Exhibit 1: 1→2, 21 cells. 21 cells link checkpoint 1 at R7C7 to checkpoint 2 at R5C7 with open corridors (no walls on this segment).
Exhibit 2: 2→3, 2 cells. Tight 2-cell hop — checkpoints 2 and 3 sit near each other; still visit every intervening cell exactly once.
Exhibit 3: 3→4, 3 cells. Tight 3-cell hop — checkpoints 3 and 4 sit near each other; still visit every intervening cell exactly once.
Exhibit 4: 4→5, 12 cells. 12 cells link checkpoint 4 at R5C6 to checkpoint 5 at R2C2 with open corridors (no walls on this segment).
Exhibit 5: 5→6, 14 cells. 14 cells link checkpoint 5 at R2C2 to checkpoint 6 at R3C2 with open corridors (no walls on this segment).
Exhibit 6: 6→7, 4 cells. 4 cells link checkpoint 6 at R3C2 to checkpoint 7 at R4C2 with open corridors (no walls on this segment).
Exhibit 7: 7→8, 14 cells. 14 cells link checkpoint 7 at R4C2 to checkpoint 8 at R4C3 with open corridors (no walls on this segment).
Verdict: 64-cell Hamiltonian path satisfies checkpoint order and wall constraints. Case closed.
