Bubble Master is a bubble-shooting game that uses bubbles that act like bouncing balls. It tasks the player with popping chains of three or more bubbles using a dotted targeting line, a ring shooter and projectiles. The game doesn't use a timer. Instead, it offers endless play. The player must remove the bubbles as quickly as possible to prevent the rows from sliding to the bottom of the playfield.
Any bubbles below the chain drop, bounce around and fall into glowing holes in the ground marked with levels of points. The associated points change as the game adds more colors of bubbles over time. For example, the holes start from left to right with 60 | 120 | 300 | 120 | 60. After the game adds yellow bubbles, the holes update to 50 | 100 | 250 | 100 | 50.
The player can shoot the top projectile bubble in the shooter or swap it with a second bubble that better matches the closest two or more bubbles. If they create chains consecutively without disruption, they can earn boosters to help them remove more bubbles faster. For example, they can use a bomb bubble or a laser beam bubble to remove large areas of matching and non-matching bubbles.
Bubble Master rewards the player with additional boosters and points for performing certain tasks. They receive a reward when they reach specific levels of points. They can also receive rewards if they watch advertisements.
