I solve LinkedIn Zip #496 checkpoint by checkpoint on a 8×8 grid. 16 numbers to hit in sequence, 0 walls to respect. My route breaks into 15 hops: 1→2 (15 cells), 2→3 (3 cells), 3→4 (16 cells), 4→5 (4 cells), 5→6 (3 cells), 6→7 (2 cells), 7→8 (5 cells), 8→9 (5 cells), 9→10 (2 cells), 10→11 (4 cells), 11→12 (4 cells), 12→13 (2 cells), 13→14 (6 cells), 14→15 (2 cells), 15→16 (5 cells).
Before the first stroke I mark walls and the next checkpoint — on this board that means Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.
I draw hop 1 next — checkpoint 2 at R5C1 after 15 cells from R4C8. Open corridor — no walls on this hop.
I draw hop 2 next — checkpoint 3 at R6C2 after 3 cells from R5C1. Open corridor — no walls on this hop.
I draw hop 3 next — checkpoint 4 at R4C7 after 16 cells from R6C2. Open corridor — no walls on this hop.
I draw hop 4 next — checkpoint 5 at R6C6 after 4 cells from R4C7. Open corridor — no walls on this hop.
I draw hop 5 next — checkpoint 6 at R7C7 after 3 cells from R6C6. Open corridor — no walls on this hop.
I draw hop 6 next — checkpoint 7 at R7C6 after 2 cells from R7C7. Open corridor — no walls on this hop.
I draw hop 7 next — checkpoint 8 at R6C3 after 5 cells from R7C6. Open corridor — no walls on this hop.
I draw hop 8 next — checkpoint 9 at R3C4 after 5 cells from R6C3. Open corridor — no walls on this hop.
I draw hop 9 next — checkpoint 10 at R3C3 after 2 cells from R3C4. Open corridor — no walls on this hop.
I draw hop 10 next — checkpoint 11 at R5C2 after 4 cells from R3C3. Open corridor — no walls on this hop.
I draw hop 11 next — checkpoint 12 at R2C2 after 4 cells from R5C2. Open corridor — no walls on this hop.
I draw hop 12 next — checkpoint 13 at R2C3 after 2 cells from R2C2. Open corridor — no walls on this hop.
I draw hop 13 next — checkpoint 14 at R3C7 after 6 cells from R2C3. Open corridor — no walls on this hop.
I draw hop 14 next — checkpoint 15 at R3C6 after 2 cells from R3C7. Open corridor — no walls on this hop.
I draw hop 15 next — checkpoint 16 at R6C5 after 5 cells from R3C6. Open corridor — no walls on this hop.
Finished — every cell filled, no revisits, walls respected. Checkpoints sit close together on the grid — short numbered hops still need full-cell coverage between them without revisiting squares.
