The goal of the game is to beat each level as quickly as possible by clearing the board of
all bubbles. Bubbles are removed from the board when a cluster of three of more of the
same type is formed. The game is over when any bubbles on the board extend below
the bottom line. To make things more difficult, the entire board is shifted down every
time a certain number of shots have been fired. Points are awarded depending on how
quickly the level was completed.
