Bubble Shooter HD 2 is a classic bubble-popping variant based on Bubble Shooter HD. It's presented with beautiful, high-definition, multicolored bubbles that seem coated with glossy paint. To win, the player must pop the bubbles in groups of three or more identical-colored bubbles across three difficulty levels for as long as possible. Their goals are to earn a high score and prevent the bubbles from sliding to the bottom of the playfield.
The player starts by selecting a difficulty level. They can either use the hamburger icon and Difficulty button or select the preset Novice text to choose a level (i.e., Novice, Expert or Master). They then review the projectile bubble in the shooter, which features a semi-translucent, frosted targeting arrow and look for matches on the field. They can only pop three or more identical, linked bubbles. When they shoot a projectile at a color-matched playfield bubble that's linked to other matching bubbles, the game bursts the group and any bubbles connected to it underneath in flashes of white and color-matching rings.
Bubble Shooter HD 2 penalizes the player any time they fail to make the shot. After they fail five times, as indicated by disappearing gray bubbles, the game slides a new row of bubbles onto the field. The game makes the challenge more difficult over time by sliding more than one row onto the screen at a time.
The player's score updates at the top of the screen. Their best score ever is presented near the top-left corner with a trophy icon. If the player wants to review their stats, they can select this area or use the hamburger icon to access the Stats button.
