Yu - Gi - Oh ! Duelist - Duel 039 " Choose Wisely ! " , known as " Which One ! ? " in the Japanese version , in the thirty - ninth chapter of " Yu - Gi - Oh ! Duelist " and ninety - eighth chapter of " Yu - Gi - Oh ! " . Summary . Dark Yugi and Jonouchi have just defeated the Meikyû Brothers . Anzu Mazaki , Ryo Bakura and Hiroto Honda celebrate , while Dark Yugi and Jonouchi collect their Star Chips , bringing them both up to 10 , enough to enter Pegasus Castle . The brothers smile and point out that the game is not over yet . Although Dark Yugi and Jonouchi have earned the brothers ' respect for defeating them in their own Labyrinth , they have not really won until they can leave the maze . Jonouchi is distressed , but Dark Yugi smiles confidentially . He remembers what they said ; There are two doors , one of which leads to the surface . He and Jonouchi may only open the door of the brother they defeat . However they defeated the two brothers at the same time , so both doors should open . The Meikyû Brothers refuse to allow this . Despite the objections of Dark Yugi ' s friends , the brothers tell them they must choose which door to open ; either the Mei door on their left or the Kyû door on their right . Meikyû the Younger says he will give a hint ; his door is right , but Meikyû the Elder argues that his is right . Jonouchi tells them to shut up ; he knows one of them is lying , but not which one . Dark Yugi thinks back to when Jonouchi asked the Meikyû Brothers to point to their door . Both of them pointed to the Kyû door , making it look like Meikyû the Elder was the liar . But Dark Yugi realizes that he did not actually speak , meaning he did not " say " a lie . Jonouchi falls back in his chair , exhausted from thinking too much . The brothers continue to smile malevolently and think to themselves that it is 100 % impossible for their opponents to choose the correct door . Dark Yugi observes that the brothers are very confident that he and his friends will pick the wrong door , even though they should have a 50 - 50 chance . Dark Yugi looks at the four possibilities , the Mei door is right , the Kyû door is right , both doors are right , both doors or both are wrong and there is a third door elsewhere . Meikyû the Younger suspects that they are suspicious that there may be more than two doors and allows them five minutes to search the hall . As the others search the room , Dark Yugi sits still and says it is easiest to judge the correct door from his spot . While searching , Bakura starts to hear a voice . The spirit of the Millennium Ring , Dark Bakura , asks Bakura how much longer is he going to spend playing card games , when a new Millennium Item is just a stone throw away from them and tells Bakura that he has been guiding him to it the whole time . Dark Bakura asks Bakura to put him on and he will tell him where the door is , it will be easy for a thief like him . Anzu notices that Bakura is acting strange and asks what is wrong . Bakura says nothing is wrong and they continue searching . Dark Bakura asks Bakura if he is afraid of him , because of what happened before , but insists that he is a new person now and just wants to help Bakura save his friends . Bakura tells him to stop and that he refuses to listen to him anymore . Dark Bakura tells Bakura that if he does not put him on , his friends will be trapped here forever . The brothers announce that the five minutes are up and everyone returns to the table , with no success in finding another door . Dark Yugi has deduced that there is one way for them to choose the right door . He has a plan , but it is a gamble . He writes the kanji for " Mei " and " Kyû " on a pair of coins . Meikyû the Younger laughs at the idea of him deciding this with a coin toss . Dark Yugi tells him to be quiet and explains that he has one coin in each hand . He puts them both on the table . The coin he leaves in his hand will show the door he chooses . He raises his left hand , showing the Kyû coin . Meikyû the Younger deduces that Dark Yugi has chosen the Mei door . Dark Bakura , now in control of Bakura tells Yugi that he is wrong ; Kyû is the correct door . Dark Yugi and Anzu look at Bakura oddly , not knowing Dark Bakura is in control , but are interrupted by the brothers who say it is too late and Dark Yugi has chosen the wrong door . Meikyû the Younger opens his door , revealing the key to the exit . He starts laughing that Dark Yugi and his friends must now stay in the Labyrinth . However Dark Yugi smiles and tells them that they gave away everything ; judging by their confident facial expressions , he knew that he would not be able to choose correctly , because there is no correct answer . Had he chosen Mei , they would say Kyû is the correct door and vice versa . Dark Bakura agrees and adds that the brothers would decide the correct door , after knowing what their opponents had chosen and calls it a perfect swindle . Anzu is surprised by Bakura ' s change of nature . Meikyû the Younger says that that does not matter , Dark Yugi still answered incorrectly . However Dark Yugi grins and lifts up his right hand , revealing the other coin also had the Kyû symbol , meaning he had chosen the Kyû door . Dark Yugi tells them how the coin under his right hand had Kyû written on one side , while the first one he revealed had Mei on one side and Kyû on the other . He laughs and says that he forgot to tell them , one of his hands does not play fair . The Meikyû Brothers become enraged that Dark Yugi managed to conquer the Labyrinth . Bakura returns to normal , unaware of what just happened . Dark Yugi wonders if Bakura had also managed to figure out the brother trap , but either way he was saved by him shouting , preventing the brothers from noticing his double - sided coin . The group exits the maze , with Pegasus Castle as their next stop .
