Space Balls Shooter is a bubble-shooting game with an outer space theme. The player attempts to earn points and play as long as possible by knocking clusters of three or more bubble balls from a pattern that slides down a playfield. They also attempt to earn enough points to change the theme.
The game provides the player with score goals (i.e., 1,000, 5,000, and so on). The player doesn't immediately see these goals until they lose the first time. They lose a game if they allow the pattern to slide so far down the field that it reaches the bottom.
Space Balls Shooter helps the player remove clusters and mixed-color bubble balls in a wide range of ways. The player receives previews of the next two projectiles at all times to the left of the arrow shooter, which can help them plan their shots. They also receive a spotlight-style targeting line. The game provides boosters inside some bubbles as well that they can hit with any projectile, no matter the color.
For example, when the player hits a bubble that displays a clock, the game temporarily stops the slide. If they strike a bubble that has double horizontal arrows, the game knocks all bubbles horizontally at and below that booster bubble off the field.
The player can use a double-arrow button in the lower-right corner of the follow-up screen after a loss to continue forward with their goal of reaching the next theme. When they play using this arrow, the game adds all new points to the total.
