Balls and Bubbles is a bubble-popping game. The player must remove bubbles from a playfield to reach crowns encased in bubbles across 180 levels.
The player starts by receiving the option to play as a guest or save their play with a personal account. The game then displays rapidly dropping bubbles that slide down the playfield, a cannon with two non-swappable projectiles, and a short glowing targeting ray. The player must shoot projectiles quickly at two or more matching groups of bubbles to create poppable clusters of three or more. They must also prevent the bubbles from sliding down to a pulsing purple horizontal laser line positioned directly above the cannon.
Balls and Bubbles doesn't require the player to remove all bubbles from the playfield. They merely need to shoot a projectile at the bubble that encases the crown.�
The game helps the player in several ways. At the lower-right corner, the player can use a tool up to five times to push the sliding pattern back to the top of the field. They also receive access to a fireball up to five times to explode large clusters of bubbles. They must use the tools carefully.
