1 vs 100

1 vs. 100 was a massively multiplayer online game show video game developed and published by Microsoft Game Studios for Xbox 360, and an adaptation of the trivia game show of the same name.

Summary
here were two versions of the game, referred to as 1 vs. 100 Live and 1 vs. 100 Extended Play. The Live version was hosted by Chris Cashman in North America and James McCourt in the UK and Ireland, and places a single contestant as "The One" against a group of 100 that make up "The Mob", with the rest of the players making up "The Crowd". The One has the opportunity to win up to 10,000 Microsoft Points, credited to their Xbox Live account, while the remaining members of The Mob divide up the winnings and each win an Xbox Live Arcade game if they are able to eliminate The One. The top three players in The Crowd win the XBLA game as well.

The hosts and players were represented by Xbox Live Avatars. The game was free to all Xbox Live gold subscribers and was supported by advertising revenue. Seasons lasting 13 weeks consisted of various 30-minute extended play sessions followed by live two-hour episodes airing Tuesday and Friday.

Season 2 of 1 vs. 100 began on November 19, 2009 in France, Germany, the United States and Canada, and on November 20, 2009 in the United Kingdom and in the Republic of Ireland.

On July 15, 2010, Microsoft confirmed that 1 vs. 100 wouldn't return for a third season.

On November 11, 2021, multiple gaming news outlets have started reporting rumors saying a revival of the game is in development, according to journalist Jeff Grubb, who claimed on his Giant Bomb show that the game is currently in active development at AltspaceVR, which is part of Microsoft’s Mixed Reality division.

Gameplay
At the beginning of each 1 vs. 100 Live round, a player is selected as "The One" and 100 players are selected to be "The Mob". Everyone else remains in "The Crowd". Selection is based on weekly, round, and season (lifetime) score.

The game's rules are nearly identical to the game show's: a question is posed, and both The One and The Mob must select an answer from three choices. If The One gets the question wrong, the game is over and the prize money is split up amongst The Mob. If The One gets the answer right, members of The Mob who got the question wrong are eliminated. The payout goes up for every tenth member of The Mob eliminated. The One can opt to quit with their winnings at various intervals, or press their luck and continue on.

The Live version adds the notion of "The Crowd", which allows hundreds of thousands of players to compete alongside The Mob and The One. The top three members of The Crowd win an Xbox Live Arcade game. The Crowd represents one of the three "helps" available to the one, which can be used at any time to lock in their answer. If The One fails to answer the first three questions, the helps are automatically used. The helps are:


 * Trust the Mob - The One's answer becomes whatever the majority of The Mob answered.
 * Trust the Crowd - The One's answer becomes whatever the majority of The Crowd answered.
 * Trust the Top 10 - The One's answer becomes whatever a majority of the 10 top scoring players in the current round answered from the crowd or mob. (In the first season, this was known as "Trust the Brain" which took the answer from the top performing player)

The better a member of The Crowd does, the better chance they have of being selected to be a part of The Mob or The One. Selection is based upon statistics for speed, accuracy, and the number of questions answered for that week. A player can only be chosen as The One once per season and as a member of The Mob once per Primetime episode. Each season will give players an opportunity to earn another 200 gamerscore.
