The latest in the Ville series of games that includes FarmVille, CityVille, and CastleVille, players will design and build a dream house and then invite friends over, CNET.com reported.
When interacting with someone in the house with them, players can move up in levels of the game by interacting with them in ways that the game sees as "romantic," Zynga executive producer David Gray said.
As players make their way up the game's experience tree, they eventually can unlock the capability to initiate virtual sex, Gray said in an interview.
The onscreen characters will begin to disrobe, although not completely, and will disappear as the bed in the virtual bedroom is covered with little floating hearts.
The game is not age-restricted, Gray said, since it requires a Facebook login so Zynga can rely on Facebook's own age restrictions.
The game will include an option, when talking with an on-screen character, to click over to see their real-world Facebook profile, CNET.com reported.
