"Enigma" was released as the third single from Lear's second album, Sweet Revenge. Depending on territory, "Run Baby Run", "Hollywood Flashback" or "Gold" made the single B-side, all from Sweet Revenge. Different edit versions of the song appeared on respective releases. Unlike other three singles off the album, "Enigma" did not belong to the concept suite on side A. The track was composed by Rainer Pietsch and produced by Anthony Monn. Amanda Lear provided self-penned lyrics.

"Enigma" met with considerable success, charting at around Top 10 in the Netherlands and Italy, and remains one of Lear's most memorable tracks of the disco era. The singer intensively performed the song on TV as well as in her erotic 1978 movie Follie di notte, where it made the final. In 1998 Amanda re-recorded "Enigma" for her Back in Your Arms album.

In 2004 the song was used as the background for Kinder Bueno television advertisement. The short film was extensively broadcast in Central-Western and Eastern European countries, such as Poland, Czech Republic and Hungary. It brought Amanda Lear back into spotlight and got "Enigma" into radio airplay. Lear's low-pitched voice caused a stir among TV audiences who initially assumed that the song was performed by a man, since the singer didn't appear in the advertisement.

A music video was produced as a part of Italian TV show Stryx. It pictures Amanda in a bright pink outfit, known from the "Follow Me" video, performing the song with three black kittens, surrounded by other cast members of Stryx. It was directed by Enzo Trapani.
