There is a large playing field filled with colorful balls in the game Big Bubble Shooter. They will descend from above on you. A ball cannon can be used to clear the playing field. If there are more than three balls of the same color, the group will burst.
Big Bubbles is an eat-and-grow survival game. Your goal is to float around bubbles as a bubble, eating the smaller ones to grow and avoiding the larger ones to stay alive.
