- Germans Love David Hasselhoff: A British version premiered in 1988 as All Clued Up, and lasted for four seasons (mainly in daytime as a weekly or by-weekly show) through 1992. Surely, it might have lasted longer had ITV not ousted TVS (which distributed the series) as its Southern England franchise in favor of Meridian.
- Hey, It's That Sound!: The Big Win Sirens used in season 2 were later recycled by several other shows, including fellow Lorimar/WB show Fun House (1988), and its rival Double Dare (for some failed "adult/celebrity" pilots hosted by Caitlyn Jenner), and finally by Supermarket Sweep, which Johnny Gilbert also worked on.
- Keep Circulating the Tapes: Reruns, if any, didn't last very long after the show's run ended. For several years, the only footage floating around on the internet was of Dan and Laureen Chrisafuli's million dollar round from the second season before full episodes started getting uploaded.
- Name's the Same: ...Well, kinda. The earliest episodes were announced by Mark Summers, not to be confused with game show host Marc Summersnote .
- What Could Have Been:
- Apparently, a third season with a revamped format was planned, but got canned after the ratings dropped for season 2.
- The show allegedly had its roots in a 1979 pilot called The Letter Machine; whether or not it's actually real is unknown.
