It was originally hosted by Arthur, the former vice-president of Endemol-France and a popular radio presenter.
Other factors particular to the French version are that the prize is shared with a viewer who has phoned in to enter the competition and that offers of an "échange" (change of box) are fairly frequent.
The number of French regions stated on the opening titles was also 24, two more people representing an overseas department (départements d'outre-mer) and an ex-pat.
A short-lived reboot of the show hosted by Julien Courbet aired on C8 in 2014 and 2015, with the top prize lowered to €100,000.
On a special edition on 2 June 2006, a correct answer was worth €50,000, which could have boosted the value of the Joker box to €1,100,000.
The jackpot prize starts at €1,000 and increases by €500 for each time it is not won as a bonus by opening the box containing it within the first three picks.
Since 31 August 2020, the top prize is replaced by another jackpot, which starts at €250,000 and increases by €5,000 for each time it is not won.
At the end of each game, the contestant is asked if he or she wishes to buy the 25th box (25ème boîte) for the amount already won on the show (except for the jackpot).
