Bubble Master is an endless bubble-popping game that features ball-like bubbles that bounce. Against a backdrop of fir trees in an empty nighttime landscape beneath a starry sky, the player's goal is to earn a high score while popping clusters of three or more bubbles with matching projectiles. They must also try to keep any row bubbles from reaching the bottom of the field. If they can't keep up, they lose the game.
The player uses a golden ring shooter with swappable projectiles and a brightly glowing, white-dotted targeting line. They receive points in three ways. The bubbles they shoot in a cluster pop and the game assigns points immediately. Any non-matching bubbles connected to only the cluster drop, bounce and then fall into points-designated colored holes near the bottom of the field. The game increases the points whenever the player does well with consecutive hits (i.e., 50, 100, 250, 100 and 50 to 60, 120, 300, 120 and 60). Lastly, the player receives points as rewards for completing specific playfield tasks and watching ad videos.
Bubble Master reveals multipliers for consecutive hits inside the ring. The player eventually receives boosters for precise hits that pop bubbles every time. For example, they receive bomb and laser bubbles that pop multi-colored bubbles across large blast zones.
