Crésus was the first French version of the Argentine quiz show El Legado that debuted on commercial station TF1 on July 4, 2005, presented by Vincent Lagaf'. Following a strong summer ratings run, the show was recommissioned, and began its second run in January 2006. Its third and final run ended at the beginning of September 2006.
The show's name was derived from a French proverb, to be 'riche comme Crésus'. Croesus was a notoriously wealthy king of Lydia from 561/560 to 547 BC, and participates in the show as a resurrected, computer-generated skeleton that interjects insults and additional knowledge alongside Lagaf'.
The second French adaptation of El Legado is Les 12 Coups de midi, which premiered June 28, 2010 on TF1.
Each player is given €50,000 before Round 1, "L'une ou l'autre" (One or The Other) in series 1 & 3 - renamed "La Réponse Masquée" (Hidden Answer) in series 2 - where each player is given a question along with an answer; the player must decide whether the correct answer is the one they've been provided or the second answer yet to be revealed. An incorrect answer means the player loses a life; a second incorrect answer means they face the 'Duel', where they must nominate a player to answer a multiple choice question, the difficulty of which varies according to the contestant's choice of a random A-B-C element. If they get it right, they stay in the game and their opponent is eliminated, along with seizing whatever sum of money was in the opponent's pot, and vice versa should the contestant get it wrong.
Round 2 comprises "La Patate Chaude" (Hot Potato) - "Le Cadeau Empoisonné" (Tainted Gift) in series 2 - "Ça passe ou ça casse" (Make or Break) in series 3 - each contestant receives three answers to a question without seeing the question itself; having seen the answers, they decide if they want to play that question; if not, they designate another player to answer it; should that player get it right, the player that passed loses a life; an incorrect answer at any point loses a life, also; two lost lives lead to a 'Duel' once again. In series 3, the format is inversed: the question is given to the player, who has to guess the correct answer.
Round 3 comprises "La Décharge Électrique" (Electric Shock) in series 1 & 3 - "La Mort Subite" (Sudden Death) in series 2 - the three remaining contestants are provided with 10 answers to a question. One of them is wrong; contestants take it in turns to keep giving answers until someone opts for the one incorrect option, leading to an instant 'Duel'.
