100% was a game show where three contestants answer a series of multiple-choice questions only by pushing buttons corresponding to the answers.


On each question, the three players involved would take three seconds or less to push buttons on the set corresponding to the multiple-choice answers. Each correct answer scored 1%. After 100 questions, the player closest to 100% won £100 and continued as the champion.


The original twist to the show was that, throughout the whole game, the players were told the individual scores (as a percentage of the number of questions answered correctly to that point), but not the player to whom those scores belonged. The scores were given to the contestants after 10, 30, 50, 60, 80, and all 100 questions had been asked, as a percentage of the number of questions they had correctly answered to that point. They were also told whether there had been a change in the lead.

Later on, the rules were changed so that the players now knew who had which scores for the first 50 questions. In all cases, the home audience could see who had what score and during the last ten questions the scores were displayed on screen after each answer.

Question FieldsEdit

Originally, the format of the show was that 100 questions would be asked without an overall subject. In its later format, the subject would change every ten questions, with 1–10 and 81–100 being general knowledge. Every fifth question was a true or false question, and Question 100 took the form of a ludicrous fact that was almost always true. In the case of a tie, a 101st question, always true or false, was asked, and if both players got it right the faster player to answer won.

The players did not speak at all during each episode, other than to state their names and towns at the start of the show; the winner only responded whether he/she would be able to return.
