The goal of Bubble Bath Babes is to steer clusters of rising bubbles and place them so that they connect to other bubbles of similar color along the top of the screen. If the sufficient amount of similar bubbles are touching, they will be cleared and all free neighbouring bubbles will rise further, allowing for combos. If the accumulated bubbles on screen reach the bottom of the playing area, the game is over. Source: Wikipedia, "Bubble Bath Babes", available under the CC-BY-SA License.
