Zip #4 Hints & Answer

Zip #4 is solved as one unbroken stroke from the first anchor to the last. We split the route into 3 manageable steps below. This one has plenty of twists, so time each turn carefully. Follow each one and you'll fill the grid without ever crossing a wall.

Step-by-step solution

1. Step 1

   From anchor 1, trace the path upward toward 3. Take it cell by cell — each square must be used exactly once, so commit to the line that keeps every later number reachable. This stretch sets up the rest of the solve.

2. Step 2

   Continue from 3 and work rightward until you reach 6. Notice how the route avoids doubling back; if you ever feel boxed in, you turned too early. Keep the path clean here and the next anchors fall into place.

3. Step 3

   Now link 6 to 8, heading winding. The key is to fill the cells along the way without stranding any corner — a single skipped square breaks the one-line rule. Move deliberately and verify each step extends the path.
