I solve LinkedIn Zip #491 checkpoint by checkpoint on a 6×6 grid. 6 numbers to hit in sequence, 12 walls to respect. My route breaks into 5 hops: 1→2 (12 cells), 2→3 (4 cells), 3→4 (12 cells), 4→5 (5 cells), 5→6 (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 R3C1 after 12 cells from R2C5. Open corridor — no walls on this hop.
I draw hop 2 next — checkpoint 3 at R5C2 after 4 cells from R3C1. Open corridor — no walls on this hop.
I draw hop 3 next — checkpoint 4 at R4C4 after 12 cells from R5C2. Open corridor — no walls on this hop.
I draw hop 4 next — checkpoint 5 at R3C3 after 5 cells from R4C4. Open corridor — no walls on this hop.
I draw hop 5 next — checkpoint 6 at R4C6 after 7 cells from R3C3. 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.
