While playing the game, press Start to display the options menu. Although the touch screen
is obscured, the timer will stop. You can then look at the top screen and take as much
time as desired to determine your next move. Resume the game, make your move, then pause
the game again and repeat.

Collect 40 stars.

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).
