Plot
The story begins in Ancient Egypt, with the prince of the dynasty, who often spends time at the duelling ground playing against others in the village. Him together with his friends Teana and Jono notice suspicious behaviour on behalf of the Mages, particularly one named Seto. On returning to the palace one day the prince is confronted by Heishin who forces him into a duel, to take only Millennium Item not in possesion of the Mages, the Millennium Puzzle, which Simon Muran hands to the prince before the duel. Heishin ultimatly wins (no matter if the player can defeat him or not, he will keep challenging until he wins). To avoid handing over the Millennium Puzzle, the prince is forced to shatter it. Simon manages to seal the princes soul in the puzzle until it gets re-assembled.

A millennnia later the puzzle is solved by Yugi Moto. Yugi has a dream at the before entering a Duel Monsters tournament hosted by Kaiba Corporation. In this dream he meets the prince inside the puzzle and is given six blank cards. After waking he meets Shadi who is curious about Yugi. Yugi tells him about the dream and Shadi tells him the name of the man in the dream is Yami.

Throughout the tournament Yugi is faced by holders of the other Millennium Items after Yugi defeats each of them their items becomes sealed in the blank cards that the prince gave him. After Yugi seals all six of the items a display of lights appears signalling the princes return to Ancient Egypt, to which yugi responds "Is this what you wanted Yami?".

The prince returns to the Dynasty to find it taken over by the Mages. He defeats the High Mage at each shrine surrounding the dynasty to take the items from them. He then heads for the shrine located in the dynasty. After passing the labyrinth at the start of the shrine he meets Seto, who reveals plans to betray Heishin and promises to help the prince, by leading him to the resting place of the items. But, last minute he reveals how he has double-crossed the prince too and managed to use him to gather all the items in the place he can use them to obtain ultimate power. Although he is defeated by the prince in a duel Heishin, who had secretly followed them uses the items to awaken Darknite. Darknite refuses his services to Heishin, claiming to have made no pact with the likes of him. He then turns Heishin into a card, disguisted by expectations. After stating that the card is one of the worst and the ugliest card he ever created he destroys it. Confronted by a new evil the prince reasons with Darknite, saying he must be put back to rest if he loses to him in a duel. Amused by this idea Darknite accepts, fully confident that he will win. However after losing to the prince, Nitemare does not keep his end of the bargain and transformes into Nitemare. The prince the duels Nitemare. After he is victorious he seals away Nitemare.

After the circumstances the prince becomes king. And Seto is never seen of again.

Game Mechanics
The mechanics of this game differ from Yu-Gi-Oh! Trading Card Game, and these differences are also contiguous with the PS2 game Yu-Gi-Oh! The Duelists of the Roses, but are not the same. The main differences are: The following example is used in the manual: "when "Gaia the Dragon Champion" (AP:2600) chooses Mercury and attacks "Blue-Eyes White Dragon" (AP:3000 and in attack position), "Gaia" has his AP increased to 3100, making it possible to defeat "Blue-Eyes White Dragon"."
 * A deck must be made up of exactly forty cards.
 * At the start of the player's turn, he or she draw from his or her deck until his or her hand consists of five cards; if the deck cannot, the player loses the duel.
 * The player must play at least one card to the field after drawing.
 * Cards can be "fused" in the hand without the card Polymerization; the player can fuse any amount of his or her cards together and in any order, but the chance of a "successful" fusion (where a new monster or magic or trap is made, or when a monster is strengthened) depends on the cards the player is fusing.
 * When any magic or trap card is fused with a monster that is not compatible, the magic or trap card is discarded and the monster is unaffected.
 * After fusion, cards can be played face-up or face-down. Traps that are played face-up are not activated until their condition is met.
 * Monster cards must select one of two "Guardian Stars", which allow a monster to gain five hundred attack and defence points if it has chosen a superior alignment against its opposing card; these alignments are taken directly from cosmic bodies and are arranged as follows (> means "is superior to"):
 * Mercury > Sun > Moon > Venus > Mercury
 * Mars > Jupiter > Saturn > Uranus > Pluto > Neptune > Mars
 * The Guardian Stars selected represent the type of the monster. In the 3-D battle sequence the attack the monster uses depends on the guardian star selected. For example when you summon Meteor-Black Dragon you are given the choice of Sun or Mars. Choosing Mars will cause Meteor-Black Dragon to use a fire attack and give it an attack bonus against Jupiter (typically plant-type) monsters.
 * Mercury typically represents spellcaster-type monsters.
 * Sun typically represents light monsters.
 * Moon typically represents dark monsters.
 * Venus typically represents fairy-type monsters
 * Mars typically represents fire monsters.
 * Jupiter typically represents plant-type monsters.
 * Saturn typically represents zombie-type monsters
 * Uranus typically represents rock-type monsters.
 * Pluto typically represents thunder-type monsters.
 * Neptune typically represents water monsters.
 * During the battle phase, after attacking and before damage is calculated, pressing square will take the player to a polygonic action battle screen.
 * Cards that cannot be used at that time are darkened (once a monster has attacked, its card darkens.)
 * Pressing start will end the player's turn.
