1 vs. 100 was an American game show based on the Dutch format of the same name, "Eén tegen 100". The game pitted one contestant ("The One") against 100 other contestants ("The Mob"). The goal for "The One" was to correctly answer a series of multiple-choice trivia questions, eliminating members of "The Mob" with each correct answer. With each correct answer, "The One" accumulated money from the eliminated "Mob" members.
The game format involved questions on a variety of subjects. "The One" was presented with a question and three possible answers. If "The One" answered correctly, all members of "The Mob" who answered incorrectly were eliminated. If "The One" answered incorrectly, the game ended, and any remaining "Mob" members split the accumulated prize money.
"The One" had opportunities to use "helps" or "skips" (depending on the version and stage of the game) to aid in answering questions. These helps typically involved gathering information or eliminating incorrect answers.
The prize money available to "The One" increased with each eliminated "Mob" member. Successfully eliminating all 100 members of "The Mob" resulted in "The One" winning the maximum possible prize, often $1 million.
The American version of 1 vs. 100 aired on NBC from 2006 to 2008, hosted by Bob Saget. A revival aired on GSN from 2010 to 2011, hosted by Carrie Ann Inaba. The show was known for its fast-paced gameplay and the tension between the single contestant and the large group of opponents.
