Bubble Tower is a casual bubble shooter similar to Bubble Tower 3D. In a three-dimensional environment, the player removes patterns of bubble balls attached to cylindrical towers by using projectiles to create and drop matching clusters. They must complete this task on each level before they run out of ball projectiles. They earn coins and unlock new, more challenging levels with each win.
A level typically features a smooth, white column tower with mixed-color balls hanging off the sides near the top and center. A single projectile at a time rests atop a horizontal matching-colored band near the bottom of the screen. A tab in the lower-left corner displays the number of available ball projectiles.
The player uses their controls to turn the tower left or right to align the lowest pattern balls with the shooter. The player can only drop the balls when they create clusters of three or more color-matched ones.
Bubble Tower rewards the player with the most coins when they don't use all of their ball projectiles. The coins help the player drop balls faster with three boosters below the shooter that unlock after they reach specific levels.
