A Breakout clone (also known as a Breakout-style game,block-breaking game, brick buster, or ball-and-paddle game) is a sub-class of the "bat-and-ball" genre. The genre is named for the dynamics of the player-controlled block, called a "bat" or a "paddle", upon which the game is based, which hits a ball towards another player's bat or different objects such as colored tiles (called a "brick"). The term brick buster, was coined in the early 2000s, which mostly refers to more modern games.

Breakout-style games are characterized by the addition of a wall of blocks or similar objects, that the player chips away at with the ball as part of the main gameplay. Since the release of the original Breakout arcade game in 1976, and Super Breakout two years later, there have been many clones and updates for various platforms. The profusion and notability of such games has been sufficient enough for them to also be referred to by some as a genre in their own right. Among the cloners was Breakout designer Steve Wozniak, who wrote Little Brick Out, a software version for the Apple II of his own hardware game.
