#10: Countdown (1982)
If you’re fond of mental workuts, then we have got the gameshow for you. Countdown has been on the air since it was introduced in the UK in 1982. It’s a brilliantly absorbing word puzzle and number-crunching gameshow hosted for years by Richard Whiteley.
While the premise might not sound as exciting or exhilarating as other games, Countdown has a devoted following that has kept the show on the air for 40 years, so clearly, they’re doing something right.
