- Hey, It's That Sound!: The car horns that told everyone that time was up in the main game was recycled from the late-1980s revival of The Hollywood Squares (see below).
- Keep Circulating the Tapes: Rerun on USA Network for a few months in 1994, and hasn't been seen since.
- Production Posse: Rick Rosner - creator of CHIPS, the 1983 NBC game Just Men! (hosted by Betty White and even shorter-lived than Caesars Challenge), and the 1986-89 revival of Hollywood Squares - was the driving force behind the show. As a result, he brought several of his game show compatriots with him - announcer Steve Day (who announced Just Men!) and composer Stormy Sachs (who composed all the music for Hollywood Squares).
- No Budget: It was clear the second bonus round was instituted simply to prevent too many people from winning the car; Harry Friedman would later re-use similar tactics on Wheel of Fortune.
- The show had taken a major reduction in budget between pilot and series too — the pilot had contestants betting on answering the words (with each player given $2,500 of stake money), the Instant Jackpot gained via the Lucky Slot rolled over from day-to-day, and the car on offer was a Lincoln Mark VIII. The series scrapped the betting format, reduced the Instant Jackpot to a reset-daily level, and the car on offer was typically a cheap Chevy/Geo model.
- The Pete Best: Chad Brown and Zach Ruby, who played the "gladiator" role briefly prior to Dan Doherty.
- Throw It In: Something about that giant letter cage was just so cool, the producers kept it onstage...even after they threw out the Bonus Round that used it.
- What Could Have Been: The show was titled Illusions in the planning stages, and was originally intended for syndication.
