Multi-colored bubbles tend to stick to different surfaces, which then have to be cleaned. In the game Bubble Tower, bubbles wrapped up endlessly high towers with a continuous layer. Your task is at the level- to clean the tower of bubbles, shooting at them with multi-colored nuclei. In order for the bubbles to burst, try to get into a group of three and more identical bubbles, which in color correspond to the color of the nucleus you launched. The exact hit is to make the entire one-color group burst and thus you will clean the tower in Bubble Tower.
