'''Yu-Gi-Oh! Ultimate Masters: World Championship Tournament 2006''', known as '''''Yu-Gi-Oh Duel Monsters Expert 2006''''' '''「遊戯王デュエルモンスターズ エキスパート2006」''' in Japan, and '''''Yu-Gi-Oh World Championship Tournament 2006''''' in Europe is a video game released in early Summer 2006 based on the ''[[Yu-Gi-Oh!]]'' franchise. The gameplay involves the player collecting cards in-game and using them to battle the computer players. Players may also (upon completing the Free Duel mode) battle against Decks which they themselves have designed and saved. This game comes with three promotional Yu-Gi-Oh! cards enclosed; they are "[[Helios - The Primordial Sun]]", "[[Helios Duo Megistus]]", and "[[Golden Homunculus]]". These cards were later handed out in English [[Blister Pack]]s.
This game contains every Yu-Gi-Oh! card made in English at the time of its release, with the exception of "[[Barrel Behind the Door]]", "[[Darkness Approaches]]", "[[Double Spell]]", "[[Kaiser ColosseumDragon Piper]]", "[[Gravekeeper's Chief]]", "[[My Body as a ShieldKaiser Colosseum]]", "[[Barrel Behind the DoorMind Crush]]", "[[Dragon PiperMy Body as a Shield]]", "[[Spring of Rebirth]]", "[[Mind Crush]]" and Level 5 [[Normal Monster]]s other than "[[Curse of DragonAitsu]]", "[[Steel Ogre Grotto 1|Steel Ogre Grotto #1Bottom Dweller]]", "[[OcubeamCurse of Dragon]]", "[[Bottom DwellerGiga Gagagigo]]", "[[Illusionist Faceless Mage]]", "[[King of YamimakaiJack's Knight]]", "[[Labyrinth WallKabazauls]]", "[[Mr. VolcanoKing of Yamimakai]]", "[[The Earl of DemiseLabyrinth Wall]]", "[[Molten Behemoth]]", "[[KabazaulsMr. Volcano]]", "[[AitsuOcubeam]]", "[[Giga GagagigoSteel Ogre Grotto 1|Steel Ogre Grotto #1]]", "[[Terrorking Salmon]]", "[[Woodborg InpachiThe Earl of Demise]]" and "[[Jack's KnightWoodborg Inpachi]]". Unlike previous games, the cards collected from packs have direct correlation to those released for the TCG. Players purchase packs from the original ''[[Legend of Blue Eyes White Dragon]]'' all the way up through the ''[[Shadow of Infinity]]'' series. There are also specialized packs focusing on themes ([[Machine]]s, [[Spellcaster]]s, [[Warrior]]s, etc.), and even by card type (all [[Effect Monster Card|Effect Monsters]], all Normal Monsters, all [[Spell Card|Spells]], all [[Trap Card|Traps]]). Additional packs are unlocked as you progress in the game. "[[Elemental HERO Neos|Elemental Hero Neos]]" is featured in the game prior to its release.
As with prior games in the series card passwords printed on TCG cards can be entered in order to obtain cards in the game. You can now get as many copies of each card as you want in this way (limited to one in previous games, except ''WCT 2005''), but you must pay a fixed cost for each card (costs range from a few hundred [[DP]] to in excess of 10000 DP for [[Limited]] and [[Forbidden]] cards such as "[[Pot of Greed]]" and "[[Black Luster Soldier - Envoy of the Beginning]]").
