Bubbles is a 2D action game developed by Williams Electronics and released arcades in 1982. The player uses a joystick to control a bubble in a kitchen sink. The object is to progress through levels by cleaning the sink while avoiding enemies.

Select 2 or more adjacent bubbles with the same color and pop them. The more bubbles you pop in a single tap  the more points you earn for every bubble. The goal of the game is to break as many groups of bubbles as possible. A group of bubbles consists of two or more adjacent bubbles of the same color.
