Bachelorette Party was just a graphic hack of Bachelor Party with the gender roles reversed.
The game play is the same as Bachelor Party.
Bachelorette Party is a video game for the Atari 2600. The game is a simplified version of Breakout where the "ball" is made to look like a nude woman and the "bricks" are made to look like nude men and the woman bounces back and forth sideways rather than vertically. On the left, she is repelled by a man with whom she collides and subsequently eliminates from play, or by the opposing wall. On the right, a vertical platform (said to be "Spanish Fly" in the manual) returns the depleted bachelorette to the room full of men. The right platform is controlled by the player using a paddle controller.
