From the game developer's about page: "Dark Room Sex Game is an award-winning multiplayer, erotic rhythm game without any visuals, played only by audio and haptic cues. The game can be played with Nintendo Wiimote controllers or a keyboard.

Dark Room Sex Game began its sordid life as a project for the 2008 Nordic Game Jam.

The Nordic Game Jam is an annual event held at the IT University of Copenhagen that brings students and professionals together to prototype experimental games over the course of only one weekend. This year, the theme was “Taboo”.

In Dark Room Sex Game, the player works with his or her partner to find a mutual rhythm, then speeds up gradually until climax. In four-player “orgy” mode, players swap partners randomly and compete to reach orgasm the fastest.

When we realized the phallic and rumbling possibilities of the Wiimote controller, we felt oddly compelled to finish the game.

Our idea was that a sex game would in fact be even more erotic if one stripped away all visuals and forced players to use their imaginations. Our hope was to use a combination of humor and embarrassment to make players uncomfortable, yet strangely satisfied. One could view the game as a commentary on the dull fixation on visuals in the spheres of sex and also videogames. Or, you can just view it as a cool party game."
