The game follows two batters as they navigate on-screen obstacles to score points. The objective is to hit various objects, including blocks and bumpers, while also lighting up the letters "COMMODORE" to earn bonus points.
The gameplay involves controlling the bats at the bottom and middle of the screen to hit targets and remove blocks. Each time a ball goes past the bottom bat, one of three lives is lost. The game can be played with two players who take turns playing when the other player loses a life.
