Just Bubbles is a bubble shooter with "just bubbles" as the main targets. The player attempts to earn points, achieve milestones and complete other tasks across four play modes (Endless, Survival, Strategy and Merge).
With the Endless mode, the player pops bubbles in groups of three or more at a time at their own pace while new rows slowly appear now and then on the screen. With Survival, they must attempt to earn points, continue playing as long as possible, and reach various goals while the bubbles slide rapidly down the screen. With Strategy, they must clear the playfield in as few moves as possible, while rows sometimes slide down the screen after a shot that results in no popped bubbles. Lastly, with Merge, they attempt to earn points by merging pairs of bubbles.
Just Bubbles offers four boosters to help the player achieve their goals, including burning laser beams and fast-fire sniper rifles that take out bands of bubbles, explosive bombs that explode groups of bubbles, and wild card rainbow multi balls that match any color to remove available connected groups of two or more bubbles that don't match the available projectiles. The player must watch ad videos to access these tools.
