When this chapter was printed in English in the " Shonen Jump " magazine , it used the name " Magic and Wizards " for the card game . When it was reprinted in volume 2 , it used the name " Duel Monsters " . Summary . Introduction to Duel Monsters . At the Kame Game , Sugoroku introduces Yugi ' s friends , Jonouchi and Anzu to " Duel Monsters " , a card game , which is currently popular in America . Unlike standard playing cards , " Duel Monsters " have a wide variety of card illustrations and contains thousands of different Monster and Spell Card s . Anzu is impressed by some nice artwork , while she finds some of the others kinda gross . Jonouchi asks how to play and if it is anything like . ( In the English version , he asks if it is like gambling ) . Yugi explains that it is a trading card game , involving two players , who each stake a card and the winner takes both cards . The game allows both players to be wizards , who can use their cards to cast spells or summon monsters to fight . All have different Attack and Defense strengths . The first player to run out of Life Points loses . As Yugi explains this an image of " Mystic Lamp " is shown in the background , with labels showing its name , Level , illustration , Attack ( ATK ) and Defense ( DEF ) and mentioning that there ' s a prismatic corner stamp . Sugoroku says that there are both strong and weak cards , but with so many , one could never collect them all . He ' s heard of a fan in America , who sold his house just to buy 1 card . Sugoroku himself is fan enough to have 1 amazing card . He decides to show it to them , stating that it is his greatest treasure . He holds up the card , " Blue - Eyes White Dragon " . ( In the English version , " Blue - Eyes White Dragon ' s " Type and lore are added . ) He tells them that the " Blue - Eyes White Dragon " is so overpowered they stopped production , making it very valuable . In the Japanese version , he says that some people have been killed over it . In the English version , he says collectors would pay through their nose to get their hands on one . Jonouchi suggests that they play " Duel Monsters " at school tomorrow and Yugi gladly agrees . Jonouchi asks for a pack with plenty of strong ones , but Sugoroku laughs that you can ' t tell that until you open the pack . Kaiba ' s visit . Seto Kaiba enters the shop and sees they ' re talking about " Duel Monsters " . Yugi recognizes Kaiba from their class . Jonouchi is glad to hear that Kaiba plays too and invites him to join them playing at school tomorrow . Kaiba laughs that Jonouchi isn ' t in his league and takes a look at his cards . He tosses them back at Jonouchi saying that they ' re useless and a beginner like Jonouchi could never match him . Kaiba boasts that he ' s good enough to compete at the national competition and since Jonouchi could never win against his Deck , playing against him would be pointless . He tells Jonouchi to come back , after he ' s collected at least 10 , 000 cards . Jonouchi starts to get mad and thinks to himself that he wouldn ' t lose in a real fight . Yugi tries to calm him down , saying he ' ll still play with Jonouchi . Kaiba turns to Sugoroku and asks if he has any good cards he might be persuaded to buy . Sugoroku says that he has and Kaiba notices the " Blue - Eyes White Dragon " on the counter . His hard beats and he starts to sweat , recognizing it as a legendary card . Sugoroku swipes the card back off he counter and Kaiba starts to question him , asking where he got the card , what it ' s doing here and demanding to have a look . Sugoroku agrees to let him have one look and hands him the card . Kaiba starts to stare at it in awe . He ' s never seen the card or ever thought that he ' d actually hold one . The card is powerful and rare , he thinks , if he was to own it , he ' d be invincible . Sugoroku swipes the card back off of him , saying that ' s enough . Kaiba drops open a briefcase full of cards on the counter , offering to trade all of them for the " Blue - Eyes White Dragon " . Yugi , Anzu and Jonouchi are surprised by both Kaiba offering that many cards and Sugoroku turning them down . It makes sense to Kaiba , he wouldn ' t trade the card for anything himself . Sugoroku says that he knows why Kaiba wants the card so much , however he has a good reason to hang onto it and it ' s not just because it ' s a strong card . An important gamer friend of his from America gave him the card . The card is as important to him as that friend , so he could never give it up . The same would be true if it was a common card . A picture of Sugoroku with the friend is visible behind him as he speaks to Kaiba . If you really treasure something , it grows a heart of its own and you would never trade anything for that heart , he explains and tells Kaiba to take care of every card in his briefcase and then he will find the true strength of this game . Kaiba slams his briefcase shut and walks out , saying he will get it later then . Jonouchi compliments Sugoroku on his speech and Yugi says that even without a rare card , his grandfather has never lost a game . School . Yugi faces against Jonouchi in a game of " Duel Monsters " , while a large group of students , including Anzu , Honda , Hanasaki gather around them . Jonouchi attack s Yugi with " Zombie " and Yugi defends with another card . As they play , some of the basic rules of " Duel Monsters " are shown to the reader . They say that each player uses a Deck of 40 cards and starts with 2000 Life Points . They take turns drawing cards and play them in either Attack and Defense Mode . When the defending player can ' t play a monster , the opponent ' s monsters Attack Points are deducted from their Life Points . When a player ' s Life Points reach 0 , they lose . The Japanese version also includes the rules for calculating damage and determining which monsters are destroyed during battles . Yugi starts his turn and Summons " Blackland Fire Dragon " . He uses it to attack and destroy " Zombie " , dropping Jonouchi ' s Life Points from 2000 to 1500 . Jonouchi starts to panic and says he ' ll use his secret weapon , but Yugi beats it too . After he loses , the other students laugh and Jonouchi and his secret weapon for being weak . Kaiba laughs to himself that that was such a low level Duel and even the elementary school students at the nationals are better than them . Kaiba addresses Yugi and tells him the Duel was fun to watch and asks if Yugi has the " Blue - Eyes White Dragon " in his schoolbag . Yugi is impressed and asks how Kaiba knew it was there . He says he begged his grandfather to lend it to him for one day , but had to promise not to play with it . Kaiba asks to be shown it one more time . Since he saw the card yesterday , he hasn ' t been able to sleep , he ' s been so excited , he tells Yugi and says that what his grandfather told him yesterday has taught him what it means to love the cards . Yugi agrees and to show it to him and hands Kaiba the card . Kaiba admires the card and quickly swaps it with a counterfeit he made . He hands back the counterfeit , thanking Yugi and saying that holding the card makes him love the game more . Kaiba tells them to have fun with their game and leaves . Yugi looks at him suspiciously , until Jonouchi calls him for a rematch . After school . Kaiba leaves school , laughing that there ' s no way he ' ll lose the next tournament , but hears Yugi call after him . He worries slightly and asks Yugi if he ' s on his way home . Yugi asks Kaiba to give back the card . He didn ' t want to ask him earlier because everyone was watching , he explains . Kaiba acts innocent , asking if Yugi thinks he stole the card , and points out that he gave it back to him . Yugi says that he can tell the difference between a real and a fake and asks again for the card back . He tells Kaiba that the card is important to his grandfather and if he doesn ' t keep his promise and give him back the card , it ' ll break his heart . Kaiba still claims to have not taken it and asks Yugi about his own feelings ; why doesn ' t he believe his friend before complaining about his grandfather ? Yugi objects , causing Kaiba to lose his patience and hit him over the head with his briefcase . Kaiba states that he doesn ' t care about loving cards and stupid things like that and asks Yugi to tell his grandfather that it ' s not how you play the game , it ' s whether you win or lose . Yugi changes to Dark Yugi , who says he must teach Kaiba a lesson with a Shadow Game and when he ' s done , he ' ll take back his grandfather ' s card . The Shadow Game . Dark Yugi and Kaiba sit down at a table to play " Duel Monsters " . Kaiba can ' t believe that Yugi challenged him to a game . Dark Yugi explains that the rules of this " Duel Monsters " game will be slightly different than what Kaiba ' s used to . Sounds like fun to Kaiba , but he doesn ' t think his cards will lose , no matter what house rules Dark Yugi has . Kaiba then thinks to himself , that if he ends - up in a pinch , he can use the stolen " Blue - Eyes White Dragon " and just tell Dark Yugi that he got it someplace else . Kaiba goes first and draws a Level 5 monster " Ryu - Kishin " . As Kaiba Summons the card , a real monster emerges from it . Dark Yugi smiles , reminding Kaiba that he said the game would be different . Dark Yugi Summons " Blackland Fire Dragon " to battle " Ryu - Kishin " . A real " Blackland Fire Dragon " emerges from the card and uses its flame breath to defeat the gargoyle . Kaiba observes his card disappearing . Dark Yugi tells him that the monsters become real and a Penalty Game awaits the loser ; those are the rules of a Shadow Game of " Duel Monsters " . Appearances . Debuts are in bold . Featured Duels .

The character Seto Kaiba is based on a collectable card games player that a friend of Kazuki Takahashi met . Takahashi ' s friend asked this person to teach him how to play a card game , but he replied " Hmph ! Come back when you ' ve collected 10 , 000 cards " . The story made Takahashi mad , but thought the player would make a good character . Kaiba uses the man from the story ' s line about collecting 10 , 000 cards in this chapter . " Yu - Gi - Oh ! " had been a series of chapters , each with its own single storyline and featuring a different game in each story , up until this point . " Duel Monsters " proved to be largely popular , so Kazuki Takahashi decided to expand on it and base larger storylines on it . The position many monsters appeared in after being Summoned , including " Ryu - Kishin " and " Blackland Fire Dragon " were used by Konami as their artworks in the " OCG " / " TCG " , rather than the artworks the cards had in the manga . The previous " Yu - Gi - Oh ! " card game by Bandai had used the artworks featured on the cards in the manga .
