Yu - Gi - Oh ! - Episode 047 Dungeon Dice Monsters , Part 2 , known as Showdown ! Dungeon Dice Monsters in the Japanese Version is the forty - seventh episode of Yu - Gi - Oh ! . It aired in Japan on March 20 , 2001 and in the US on November 2 , 2002 . Summary . Yami Yugi and Duke Devlin have agreed to play a game of Dungeon Dice Monsters . If Yami wins , Joey will be released from being Duke ' s servant for a week - - a job that , at the moment , involves Joey wearing a dog suit . But if Duke wins , Yami must never play Duel Monsters again , giving up his title of " King of Games " to Duke . The duel arena reconfigures itself to reveal a grid of squares . Also , the duelists ' podiums now have three illuminated hearts on them . As the combatants take up their places , Yami sees that the podium is now different , featuring a similar grid of squares instead of the usual field of card zones . There is also a small computer monitor and keyboard , which Duke describes as the Help Screen , just in case Yami can ' t keep up with the rules . This brings up the next problem : Yami has no idea how this game works , but Duke apparently does . First , a bin opens near Yami , holding dozens of dice in multiple colors and with a variety of symbols on them . Duke says that Yami must choose 15 of the dice to use during this game . Yami ' s friends protest that he should explain what the dice do first , but Duke doesn ' t indulge them , instead holding out the 15 dice he ' s already picked . Yami selects his dice anyway , and they put them into a compartment that will shuffle the dice . Duke takes his turn first , and the podium gives him three of his dice at random . Duke rolls them , and two of the dice come up with the same symbol . Duke identifies this symbol as a Summon Crest , but Yami ' s wonder only increases when Duke picks up one of these two dice and presses it into one of the squares of the grid on his podium . A hologram of the die appears on the corresponding square in the arena , and the die unfolds into six red squares leading away from the foot of Duke ' s podium . The square upon which the die was placed now has a bright sphere that reshapes itself turning into a monster , " Ryu - Kishin " . Duke explains that , when a player rolls two Summon Crests , one of those dice can be used to summon a monster . These monsters then have the ability to move around on the created squares . The aim is to reach the opponent and attack one of the three Heart Points . Each attack eliminates one Heart Point , and when a player loses all three , that player loses . After Duke throws his two unused dice back into the shuffler , Yami begins his turn . He takes his three dice and rolls them decisively . To his shock , none of the resulting symbols match . Duke is not surprised , saying that his dice were at too high a level . Looking for an explanation , Yami examines his dice and realizes that there is only one Summon Crest on each of them . Duke explains that the Summon Crests on dice also feature their levels , and Level 4 dice only have one Summon Crest each . On the other hand , Duke was using Level 1 dice , which have four Summon Crests each . Of course , his monster is not strong , but at this stage , it ' s better to go for a higher chance of summoning . Yami realizes that most of the dice he picked were high - level ones , and his friends object , saying that Yami should be given a chance to re - select his dice . But Duke refuses that , and he takes his next turn . Over the next few rounds , Duke summons monster after monster ( including one high - level throw that only summons a closed treasure chest ) , while Yami can ' t summon anything . He does get two Summon Crests once , but Duke shoots him down by pointing out that the Levels of the paired dice have to match for the summon to occur . In very little time , the red squares from Duke ' s unfolding dice are well into Yami ' s half of the arena , and every die placed is one more opponent for Yami to face . Gathering all his will , Yami throws his next three dice , and he gets the high - level summon - - " Mighty Mage " . He uses his monster ' s ability to launch the first attack of the game , destroying one of Duke ' s monsters . Duke remains unworried , summoning another monster with low stats . On Yami ' s next turn , he ' s happy to see that he got some of the low - level dice he picked , and the opportunity pays off with a second monster . When Duke ' s next turn doesn ' t deliver two Summon Crests , things finally seem to be turning around . But this relief is cut off when Duke says he didn ' t want another monster this turn . He reminds his opponent that all non - Summon Crests that are rolled get stored in the player ' s Crest Pool until they get used . With this roll , Duke has increased his store of Magic Crests , and he uses four of them to activate the ability of his most recent monster . From across the playing field , " Blast Lizard " destroys Yami ' s low - level monster . Yami is back to fighting for his life , and he manages to summon one more monster , but Duke ' s monsters are already closing in . All too soon , the first one arrives in front of him , and with a blast of fire from " Gator Dragon ' s " mouth , Yami has lost one - third of his life . Yami is in a tight spot , and Duke drives the point home with his latest taunt , revealing not only his skill , but also the fact that he ' s the inventor of Dungeon Dice Monsters , which shocks Yami and his friends . So much is on the line , but how is Yami supposed to win against the creator of their game ? Featured Duels : Yami Yugi vs . Duke Devlin , Part 1 . " The Duel featured in this episode uses Dungeon Dice Monsters rules . " " Note 1 : Please note that they do not often show the dice pool or show the dice result clear enough for us to see . As a result , the total may be wrong . In order to do this as accurately as possible , I had to go back and check several times and calculate what they use . Most of the time the dice pool is wrong . " " Note 2 : Please note that the monster stats are not always the same as the real life game on the card text .

" Errors . - The first scene of Duke ' s first roll shows the white and yellow dice with LV2 Summon crests and the green one with a Movement crest , but in a close - up of the green die , it has changed to a LV2 Summon crest . - In Duke ' s hand of his second roll , the three dice include a yellow die with a LV2 Summon crest . However , his dice roll first shows the yellow die with a Summon crest without the 2 on it and a red die with a LV2 Summon crest , so the Summon crests were not the same level after the roll and therefore a monster would ' ve not been able to be dimensioned . However , the next scene changes the yellow die to show a Summon crest with 2 on it , making the Summon crests equal levels and Duke summons Yaranzo . - Yugi ' s three dice all show Summon LV4 crests when he first grabs them . However , one of his two white dice shows a normal Summon crest of LV1 after the roll , so the LVs shown on the dice changed , and with them different , he should not have been able to summon the Mighty Mage .
