In Bubble Shooter, players aim and shoot colored bubbles toward a cluster of bubbles at the top of the screen. When three or more bubbles of the same color come into contact, they pop, earning points and clearing space. The primary objective is to eliminate all bubbles before they reach the bottom line, which would end the game. As the game progresses, the arrangement of bubbles becomes more complex, requiring strategic planning and precise aiming. Some versions introduce obstacles like rock bubbles, glass, and spikes, adding layers of difficulty and requiring players to adapt their strategies accordingly.
