The 7th Guest (abbreviated as T7G in Sanger's labeling system) is a puzzle-adventure game initially released for Windows, Mac, and CD-i. Its successful release in 1993 was a breakthrough for the new CD-ROM market in videogames, and Sanger's music played a prominent role in the game.

This series includes 7 ADAT tapes and one 3.5" floppy disk.
