1 vs. 100 (British game show)

One player is selected to play the game as The One from 100 people, collectively known as The 100. To win the game outright, the One must eliminate all members of the 100 by answering a series of questions correctly.

After having the opportunity to select one of two categories, a multiple-choice question with three options is revealed. The 100 is given 6 seconds to lock in their answers before the One is given the opportunity to answer the question. If the One is correct, any members of the 100 that answered the question incorrectly are eliminated from further play, bringing the lone contestant closer to winning the game. The amount of money in the contestant's bank also increases by £1,000 multiplied by the number of members of the 100 that were eliminated in that question. If the contestant eliminates all 100 opponents, he or she claims all the money in the bank plus an extra £50,000 for defeating them. However, if the One incorrectly answers a question, the game ends and he or she leaves with nothing. Unlike other editions like the American version with the same name, if the One lost the game, the remaining players in the 100 won't share the money accumulated by the One. Also, the One cannot walk away with the cash he or she has accumulated in the game until the 100 is defeated.

At the end of the game during the last question of gameplay Dermot/Ben will announce when the last members of the 100 have been eliminated before revealing if the One has answered correctly, they will then be given an offer to bail out by refusing to answer their final question thus taking home the winnings that is already in the prize fund but the One will not collect the £50,000 for defeating the 100. If they refuse to bail and decides to play and the contestants is correct then they take home all the money plus the £50,000, but if the answer is wrong then he/she leaves empty handed.

During gameplay, The One has three “Dodges”, where if he/she doesn't know an answer to a question, they can refuse to answer the question and play their Dodge, but their prize bank will be slashed in half as of them guaranteeing their survival in the game, when the one has eliminated 75 opponents, they'll be given an opportunity to earn another dodge through the “Bonus Dodge” category but they cannot play a Dodge on that question. In addition, after the first question, the One can also use their “Double” to earn £2,000 by the number of members of the 100 eliminated if the One answers the question correctly. The maximum amount of money a contestant can win is £250,000 if all 100 people are eliminated on a question using the double without bailing out.
