The U.S. licensed version from American Video Entertainment, was released in 1991, with all adult elements removed or obscured. In the same year, a localized version leaving intact those contents was released by Hacker International in Japan as Soap Panic, and still in the U.S. by Panesian.
A Genesis / Mega Drive version was released in 1993 which is more suitable for all ages.
Summary.
Gameplay is reminiscent of the classic "Tetris" (1984) and the succeeding "Puzzle Bobble" (1994). The goal is to steer clusters of rising bubbles and place them so that they connect to others with a matching color along the top screen part. If a sufficient number of similar bubbles are touching, they will be cleared and all free neighboring bubbles will rise further, allowing for combos. If the accumulated bubbles on the screen reach the playing bottom area, it reaches game over. Finally, when a level is completed the player is rewarded with erotica.
Reception.
Allgame gave this video game a score of 2.5 out of 5 stars, saying ""Bubble Bath Babes" is most notable for being one of three NES games to feature nudity, but its bubble-matching gameplay is good enough to keep it from being just a novelty. Unfortunately, the mild adult content overwhelms the aura of the game, even though it is a small part of the overall package. The topless woman at the bottom of the screen is tastefully depicted, but her inclusion is ultimately gratuitous since she has no effect on the action." "Computer and Video Games" said "The limited graphics make the sauciness factor rubbish".
