If a contestant tries a longer word that is not in the programme's dictionaries, his or her word is rejected, but his or her opponent may score the points for its length by giving a shorter, valid word. For example, if a contestant produces a nine-letter word that is rejected and his or her opponent produces an acceptable word that is shorter, the opponent gains nine points. If both words are incorrect, no one scores. Diacritics do not count: for instance, the French word épeler (to spell) will be formed with the tiles E P E L E R. Example With the following letters: T O C E D A M I T S it is possible to get the French words dictats, amodies and mastoïde. With the following letters: R U R E T E C E R Z it is possible to get the French words recruter and érecteur. Duels There are several variations of the "duel" section: the classic version, which consists of finding two words on the same theme after 10 letters have been given, using each letter once and only once, "l'un dans l'autre" ("one within the other"): with ten given letters, find a ten-letter word and another word, within the first; one a proper noun, the other a common noun, "la bonne orthographe" (the "correct spelling"): a word is proposed and the winner is the one who spells this word correctly first, "le calcul mental" ("mental arithmetic"): the players must complete a calculation (for example, 24 × (32 − 5 × (42 ...)) in their heads. Only one answer is accepted, from the first player to provide one. If the answer is correct, ten points (originally five points) are awarded to the player giving it. If the answer is incorrect, the player's opponent receives three points. Before the regular letters and numbers rounds, a toss-up duel is played, with the winner earning a "sesame," or joker, that can be used in the final bonus game (introduced in 2016). Final sprint At the end of the game, the contestants play the "final sprint" where they have to solve two problems. As opposed to the other rounds during the game (except duels), these have been generated prior to the show and they admit at least one perfect solution (either a 10-letter word or a number that can be found with the 6 given numbers) the contestants
