During the show's thirty-minute duration three contestants compete in different tests where they have to answer trivia-like questions, putting their mental, reasoning and memory abilities to the test. Most of the questions have a moderate level of difficulty and are spread over six different games: "Cada sabio con su tema", where each contestant answer questions about a given topic of their choice; "La pregunta caliente", where contestants must answer random questions; "El duelo", where two contestants answer questions about a topic that changes daily; "La parte por el todo", where the contestants must figure out what an image, piece of text or piece of music belong to; "La calculadora humana", where the contestant with the second highest score must answer fifteen basic arithmetic operations in 50 seconds in order to keep his/her earnings for the day; and finally "El reto", where the contestant with the least score has to figure out seven words from their root and definition in order to remain in the game. If the contestant loses the "El Reto", a new individual will be chosen to replace him/her the next episode.

Mastermind is a British quiz show, well known for its challenging questions, intimidating setting and air of seriousness. Devised by Bill Wright, the basic format of Mastermind has never changed — four and in later contests five contestants face two rounds, one on a specialised subject of the contestant's choice, the other a general knowledge round. Wright drew inspiration from his experiences of being interrogated by the Gestapo during World War II. The atmosphere is helped by Mastermind's famously ominous theme music, "Approaching Menace" by the British composer Neil Richardson. The quiz programme originated and was recorded in Manchester at studios such as New Broadcasting House and Granada Studios, before permanently moving to MediaCityUK in 2011.
