In the anime, Duke invented [[Dungeon Dice Monsters]] and visited [[Maximillion Pegasus]] to demonstrate the game shortly before the [[Duelist Kingdom]] tournament. Duke was impressed by Pegasus' skill at the game. Pegasus himself enjoyed the game and approved of the creation of Dungeon Dice Monsters, wanting to expand it further. Upon Pegasus' request, Duke allowed him to make additions to the game, like the "[[Dark Magician (DDM)|Dark Magician]]" as a monster and also hacked into [[KaibaCorp]]'s computer system. However, after Pegasus disappeared after being defeated by [[Yugi Muto]] in the Duelist Kingdom tournament, Duke blamed Yugi for his disappearance and believed that Yugi must have cheated to beat a gamer as good as Pegasus. He swore to get revenge on Yugi whom he believed didn't believe deserved deserve, the title "King of Games".
After the Duelist Kingdom tournament, Duke opened the [[Black Clown]] (a rival game shop to the [[Kame Game]]) and was transferred to [[Domino High School]], the school that Yugi attends. He quickly became popular and impressed girls with a number of dice tricks. [[Joey Wheeler]] became jealous and challenged Duke to a game of [[Duel Monsters]]. They agreed to the stakes which were that if Joey won, Duke would close his shop and if Duke won, Joey would be his slave for a week. Having been the runner-up in [[Duelist Kingdom]], Joey was certain that he would win. However, not having his own Deck, Duke insisted that they play using cards straight from [[Booster Pack]]s. Joey agreed and they each created a Deck.
Duke also televises his game with Yugi. Having not played Dungeon Dice Monsters before, Yugi struggles at first and Duke gains an early advantage. However, Yugi makes a few comebacks and ultimately wins using the "Dark Magician" that Pegasus added.
Duke realizes that Yugi plays honestly and determined that he wouldn't have cheated against Pegasus. He starts to worry that the televised game was going to be bad publicity as it made him look like a bad person. However, Yugi and his friends comfort Duke, saying that Dungeon Dice Monsters has the potential to become a great game. Duke soon receives word from [[Industrial Illusions]] afterward, saying that they will be helping produce Dungeon Dice Monstersand have agreed to make the game global.
