Bubble Shooter: Color Balls is a popular puzzle game that involves shooting colored bubbles at a cluster of other bubbles on the screen. The goal is to match 3 or more bubbles of the same color in order to make them disappear. The game typically starts with a pre-arranged formation of bubbles, and the player is given a limited number of shots to clear the entire formation. As the player progresses through the game, the formations become increasingly complex and difficult to clear. Some versions of the game also include power-ups and special bubbles that can be used to clear large groups of bubbles at once.
