What CD-i?  It was a CD format made by Phillips in 1991 which worked on special players.  These CD-i players not only played CD-i discs, but audio CDs, CD+G discs (CD + graphics), VCDs (video CDs), and karaoke CDs.  The CD-i format did not succeed in the United States, but was popular in Europe, specifically the United Kingdom and the Netherlands.

Four CD-i game show adaptations were made for the American market--The Joker's Wild, The Joker's Wild Jr., Jeopardy!, and Name That Tune.  Of these four titles, the most difficult title to find is The Joker's Wild Jr.  The other three titles are relatively easy to find, with The Joker's Wild being the most common title.  In addition to these domestic titles, there was a CD-i version of Lingo released in the Netherlands in 1994.  From what I've read, this Lingo game is a very hard-to-find title.
