Overview
Puzzle Bobble 3 (also known as Bust-A-Move 3) is the second sequel to Puzzle Bobble. The game completely abandons the idea of previous titles that the playfield is being pushed down by some sort of mechanical device and instead attaches groups of bubbles to nodes that move downwards. When a node is no longer connected to any bubbles, it will disappear and when all nodes in a level have vanished the level is complete. As a result, shooting a bubble to the top of the visible playfield without striking any bubbles causes it to bounce and travel back downwards. The player is not penalised if such bubbles again leave the playing field without attaching to anything (except for adding to the number of moves until the field is pushed down by one empty line).
Gameplay is further varied by the implementation of new scrolling playfields that are several times as high as the screen and must be conquered as an endurance event. Each scrolling playfield occupies the same space on the world map as five previous levels.
