I solve LinkedIn Zip #476 checkpoint by checkpoint on a 6×6 grid. 8 numbers to hit in sequence, 16 walls to respect. My route breaks into 7 hops: 1→2 (16 cells), 2→3 (2 cells), 3→4 (14 cells), 4→5 (2 cells), 5→6 (4 cells), 6→7 (2 cells), 7→8 (2 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 R3C5 after 16 cells from R5C2. Open corridor — no walls on this hop.
I draw hop 2 next — checkpoint 3 at R2C5 after 2 cells from R3C5. Open corridor — no walls on this hop.
I draw hop 3 next — checkpoint 4 at R5C5 after 14 cells from R2C5. Open corridor — no walls on this hop.
I draw hop 4 next — checkpoint 5 at R4C5 after 2 cells from R5C5. Open corridor — no walls on this hop.
I draw hop 5 next — checkpoint 6 at R4C2 after 4 cells from R4C5. Open corridor — no walls on this hop.
I draw hop 6 next — checkpoint 7 at R3C2 after 2 cells from R4C2. Open corridor — no walls on this hop.
I draw hop 7 next — checkpoint 8 at R2C2 after 2 cells from R3C2. 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.
