Unlocking new puzzles
Each level has a different number of stars you can get. “Practice” and “Easy” give you a maximum of four stars. “Normal” gives you a maximum of five stars. “Hard” has a maximum of six stars. After collecting twenty stars, new levels will open up (usually thirty new puzzles for every twenty stars).
