Pro Tips & Strategies

1. Start with the corners. Stars sitting on edges or corners usually have only one or two possible connections. Map those first — they anchor your whole route and prevent dead ends later.

2. Trace backwards from the finish. If you get stuck, flip your thinking. Sometimes the path only makes sense when you work from the last star back to the first.

3. Avoid isolating single stars. Before committing a line, glance at every remaining star and ask: "Can I still reach that one?" A star surrounded by used-up squares is a guaranteed restart.
