I solve LinkedIn Zip #481 checkpoint by checkpoint on a 8×8 grid. 12 numbers to hit in sequence, 16 walls to respect. My route breaks into 11 hops: 1→2 (4 cells), 2→3 (7 cells), 3→4 (8 cells), 4→5 (5 cells), 5→6 (6 cells), 6→7 (7 cells), 7→8 (5 cells), 8→9 (6 cells), 9→10 (12 cells), 10→11 (7 cells), 11→12 (7 cells).
Before the first stroke I mark walls and the next checkpoint — on this board that means Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint.
I draw hop 1 next — checkpoint 2 at R4C3 after 4 cells from R2C2. Open corridor — no walls on this hop.
I draw hop 2 next — checkpoint 3 at R2C5 after 7 cells from R4C3. Open corridor — no walls on this hop.
I draw hop 3 next — checkpoint 4 at R8C6 after 8 cells from R2C5. Open corridor — no walls on this hop.
I draw hop 4 next — checkpoint 5 at R7C7 after 5 cells from R8C6. Open corridor — no walls on this hop.
I draw hop 5 next — checkpoint 6 at R5C6 after 6 cells from R7C7. Open corridor — no walls on this hop.
I draw hop 6 next — checkpoint 7 at R1C8 after 7 cells from R5C6. Open corridor — no walls on this hop.
I draw hop 7 next — checkpoint 8 at R3C6 after 5 cells from R1C8. Open corridor — no walls on this hop.
I draw hop 8 next — checkpoint 9 at R1C3 after 6 cells from R3C6. Open corridor — no walls on this hop.
I draw hop 9 next — checkpoint 10 at R6C3 after 12 cells from R1C3. Open corridor — no walls on this hop.
I draw hop 10 next — checkpoint 11 at R7C4 after 7 cells from R6C3. Open corridor — no walls on this hop.
I draw hop 11 next — checkpoint 12 at R8C1 after 7 cells from R7C4. Open corridor — no walls on this hop.
Finished — every cell filled, no revisits, walls respected. Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint.
