Various companies in the early ninetees were experimenting with bringing interactive versions of popular TV shows to CD-i. For example, SPC Vision brought a dutch version of Lingo to CD-i in The Netherlands in 1995, PF Magic was probably the first one bringing a version of USA's Third Degree show to CD-i in 1992 and even Philips itself developed an interactive version of "Name that Tune" on CD-i (this was Philips Fantasy Factory, who also developed Hotel Mario on CD-i). Finally Microids also tried it with an interactive version of Fort Boyard but unfortunately it was never released.
While most of these companies mainly tried it one time, the USA company Accent Media Productions has a broader track record of converting TV shows into games. They started with Jeopardy, continuing with Joker's Wild and after that even Joker's Wild Junior and left us with the unreleased CD-i version of Wheel of Fortune. Another version of the many Jeopardy! games released, the CD-i edition features the actual voice of Alex Trebek, but only shows him in the opening sequence and in the final round.
The gameplay is like that of the TV show; two rounds of play with six categories with a final round at the end. To answer the question the player must buzz in and put in the answer by using letters on the side of the screen. However, different from the other games is that there is no computer opponent to play against and Final Jeopardy doesn't have the answering system like the previous rounds. Instead it requires you to write it down using paper and a pen or pencil.
NintendoComplete went through a whole game of Jeopardy on CD-i "A single game, single player playthrough of Philips Media's 1994 CD-I game, Jeopardy! Even though it lacks a bit of personality thanks to the complete absence of an AI player or player avatars, it is impressive for its authentic replication of the shows sights and sounds - especially in that there are voice recordings reading every single question and answer, and it even provides a database of common names so that the game will refer to each play by name. The CD-I is justifiably notorious for the quality of the typical "game" made for it, but this was quite a respectable effort!"
From the disc: "If you’ve always anted to be on Jeopardy! (and who hasn’t), play the world’s most popular ‘answer and question’ game and feel like you’re on the set! You’re standing in front of the cameras, hand at the buzzer, as host Alex Trebek calls you by name and peppers you with categories and dollar amounts. Advance from the Jeopardy! round to Double Jeopardy! And then Final Jeopardy.challenged by the game itself and by your brilliant opponents. Win the most money, become champion and see your score immortalised in the Jeopardy! Hall of Fame. The unique response to directory on CD-I makes this version as fast paced as the television game itself."
Accent Media Productions was not the only company creating an interactive version of Jeopardy. Almost every platform has its own version of Jeopardy, like a NES version by Gametek, a Genesis version by Park Place Productions, a Sega CD version by Absolute Entertainment and the final version, until now, was released in 2012 by Pipeworks and released on Wii U, Xbox 360 and Playstation 3.
