Cresus

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'.

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.

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'.

"La Demi-Finale" sees the two remaining contestants given 70 seconds each, and are asked quick fire multiple choice questions on an alternating basis (i.e. once contestant A has given their correct answer, contestant B will be asked their question); their respective clocks stop as soon as they've given a correct answer, and keep running until they have given a correct answer to a question; the first person to run out of time loses.
