What? Where? When? (1975)

In this reality competition show inspired by "Squid Game," 456 players put their skills to the ultimate test for a life-changing $4.56 million prize.

Each Challenge pits numerous cast members from past seasons of reality shows against each other, dividing them into two separate teams according to different criteria, such as gender, which show they first appeared on, whether or not they're veterans or rookies on the show, etc. The two teams compete in numerous missions in order to win prizes and advance in the overall game.

I gathered 1,000 people to fight for $5,000,000, the LARGEST cash prize in TV history! We're also giving away a private island, Lamborghinis, and millions more in cash throughout the competition! Go watch to see the greatest show ever made!

"Come on down!" The Price Is Right features a wide variety of games and contests with the same basic challenge: Guess the prices of everyday (or not-quite-everyday) retail items. 

This game show sees contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel.

Quiz in which contestants try to score as few points as possible by plumbing the depths of their general knowledge to come up with the answers no-one else can think of.

The show where everything's made up and the points don't matter. Not a talk show, not a sitcom, not a game show, Whose Line Is It Anyway? is a completely unique concept to network television. Four talented actors perform completely unrehearsed skits and games in front of a studio audience. Host Drew Carey sets the scene, with contributions from the audience, but the actors rely completely on their quick wit and improvisational skills. It's genuinely improvised, so anything can happen - and often does.

Takeshi's Castle was a Japanese game show that aired between 1986 and 1990 on the Tokyo Broadcasting System. It featured the Japanese actor Takeshi Kitano as a count who owns a castle and sets up difficult challenges for players to get to him. Contestants throw themselves into daunting physical challenges as they attempt to storm Takeshi's Castle and win the grand prize of one million yen. The show has become a cult television hit around the world. A special live "revival" was broadcast on April 2, 2005, for TBS's 50th anniversary celebrations.

Each week, 20 contestants compete in a series of challenges in an attempt to win £10,000. These challenges are based in large pools of water or mud and generally involve large assault courses that participants must cross.

A gameshow hosted by Ant and Dec filled with stunts, sketches, and special guest appearances.
