Balls: Wall to Wall is a bubble-popping game with a unique double-trap challenge. It presents the player with a central bar shooter sandwiched between multiple rows of bubble balls. The player's ultimate goal is to reduce the number of bubbles for as long as possible and earn an all-time high score.
Yet, the player must pop all the balls before they run out of moves. If they fail, the game slides additional penalty rows down from the top and up from the bottom of the screen at the same time. The player loses the game if even a single bubble ball slides into position next to the shooter from either direction.
Balls: Wall to Wall provides the player with a single projectile at a time and a tiny laser targeting pointer. The player can only pop bubble balls in clusters of three or more color-matched ones. Any balls attached only to the cluster also pop.
If the player creates a gap in the topmost or bottommost row, they must use extreme caution. Any bubble ball that hits a solid ceiling, floor or wall surface bounces. As a result, an attempt to complete a cluster by using one of these gap spaces leads to the ball bouncing away to the opposite side of the field.
