Glossy Bubbles Challenge is an endless bubble-shooting puzzle game that features glossy, mixed jewel-toned bubbles. The player's goal is to knock bubbles that slowly slide down the playfield into colorful cups using a two-projectile ring shooter and a dotted aiming line for as long as possible to achieve a high score. They must also prevent any bubble within the pattern from sliding below a white horizontal line.
The playfield background starts out with a couple standing in front of the Eiffel Tower in Paris at night with balloon hearts floating all around them. If the player is willing to watch ad videos, they can switch the background to a pastel-colored fantasy forest, a candy and dessert landscape, or a snow-covered winter village. They can also upgrade the bubbles to hold different types of theme-based objects.
The bubbles in Glossy Bubbles Challenge bounce like balls. The player knocks multiple ones from the sliding pattern by creating clusters of at least three matched bubbles with a matching projectile. If the player knocks clusters into the cups without disruption, they earn multipliers that increase their points. They also receive a fireball that can act like a wide laser beam that cuts a swath through the bubbles.
