Bubble Shooter Online is a vibrant, multicolored bubble-shooting game that makes play fun with a relaxing interface and upbeat music. The game features classic horizontal rows of mixed bubbles suspended from the top of a playfield and an arrow-style shooter. The player receives one projectile per turn. The game also allows them to see the next projectile available on a row of bubbles to the left of the shooter.
The player can choose to play as a Novice, Expert or Master (i.e. Easy, Medium or Hard gameplay). Their goal is to shoot the projectile at two or more matching bubbles to remove all connected ones from the field. The game doesn't feature any sort of targeting line or tool other than the tip of the arrow. The player also receives a rainbow-colored projectile now and then that they can use to take out connected bubbles of any color.
Bubble Shooter Online rewards the player with points. It features the current score above the playfield near the center of the screen. It also displays the best score next to a trophy icon above the playfield to the left of the current score.
