Puzzle Bobble Series

Puzzle Bobble is a series of puzzle games featuring the characters Bub and Bob from the Bubble Bobble series. The player aims a bubble launcher at a mass of differently colored bubbles. Connecting clusters of like-colored bubbles causes them to pop (and bubbles left unattached fall away). The goal is to pop all the bubbles before the bubbles reach the bottom of the shaft. The games were released in English under the title Bust-a-Move, which has led to some confusion with the Bust A Move series of dancing games.
