Dueling Arena

In the Duelist Kingdom tournament, two players duel in what's known as a "Dueling Arena." Each arena projects giant holographic images of the cards the players activate. Some arenas also contain properties of a specific type of land mass that can alter a monster's ATK and DEF. Duel Areans were also seen in the KaibaCorp building, Kaiba Land, and Duke Devlin's gameshop.
