Bust-A-Move '99

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).

5). 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. This game also marks the introduction of rainbow bubbles into the series - bubbles that are initially transparent and filled with a rainbow.

If an adjoining bubble is burst, the rainbow bubbles switch to the colour of the burst bubble, allowing the player to build up chain reactions. The ability to choose a character was introduced, but only to the VS Computer mode. As in Bubble Bobble , the first player controls Bub, and the second player controls Bob. In the Nintendo 64 version, a four-player-simultaneous option is available.
