Warm-up
Number Line Maze · 4 × 4 · by @wyattHow to play
- A number on a corner says how many walls touch it. The outside edge counts.
- Draw the walls of a maze. The outside edge is walled except the way in and the way out. Walls never close into a loop, and every wall joins the edge, so every square can be reached and there's only one way between any two.
