Bubble Shooter Lulu is a levels-style bubble-bopping game. The player must pop bubbles displayed in a pattern on the playfield on each level to reach a gold crown trapped in a bubble and complete other tasks. The game locks all levels at the start. The player can only unlock a new level by completing their task on the current one.
The game reveals the pattern before the start of play by sliding the bubbles up the screen into position. The player uses a clear, glass cannon with a pointer light beam as their shooter. An adorable kitten tosses bubble projectiles into the cannon. To remove bubbles from the field, the player uses their projectiles to create clusters of three or more bubbles.
Bubble Shooter Lulu also features powerful boosters that the player receives as projectiles during play, such as bomb bubbles, glowing white bubbles and rainbow bubbles. The player can also access these tools by buying them using the icons at the bottom of the screen.
The player receives a golden score and stars as rewards. If they allow the pattern of bubbles to slide to the ground, they fail the level. They can replay the level, watch an ad to revive the current gameplay, or quit entirely.
