Number Line Maze
Draw the walls each number asks for, then find your way from the arrow in to the arrow out.
Rules
A number counts the walls touching it. The outside edge counts too.
✓ 3 walls ✗ Not 2 walls Walls never close off a square or form a loop, so there's exactly one way between any two squares.
✓ One way through ✗ Squares shut off When the walls are right, walk from the arrow in to the arrow out.
Example: Warm-up
Playing here: Drag along the lines between numbers to draw walls; tap a line to cycle it. Then drag (or use the arrow keys) to walk out.
