Leisure Suit Larry 6: Shape Up or Slip Out! is the fifth entry in the Leisure Suit Larry series of graphical adventure games published by Sierra Entertainment. Originally developed for DOS, a remake was produced in CD-ROM format a year after its release. The enhanced version of the game offers revamped graphics in SVGA resolution and voice acting, a first for the series. Both versions use an icon interface similar to other Sierra games of the time, but unlike most Sierra games, the icon bar is visible at all times.
The plot continues the exploits of series protagonist Larry Laffer, who has won a free trip to a luxurious health spa populated by women.
Larry Laffer is once again single at the outset of the game, as his girlfriend Passionate Patti has been retconned out of the series. After competing—and losing—on the television dating show Stallions, Larry wins an all-expenses paid trip to La Costa Lotta, a refined health spa. Due to his status as non-paying guest, he is treated rudely by the staff and given the worst room on the premises. As such, none of the available women in the resort want anything to do with Larry, though it is possible to change their minds with the right gifts.
