- Not to be confused with "Playing Field".
A Duel Field is a special field exclusively used in the World Duel Carnival finals. So far, there exists four of these fields which are magma, space, jungle, and canyon. Each of them existing in the underground section of the Duel Coaster.
Relating to their names, each field occurs on a certain location such a volcano, a spacecraft, jungle and at a canyon. In each of these stages is where the eight WDC finalists will engage in one on one Duels in order to pass to the second final round of the Tournament.
In addition to this, each Duel Field is also it's own Field Spell; having an effect that will influence the duel. For example; The Jungle Field will inflict 1000 points of damage to a player who does not summon a Monster from their hand on their turn. The Sphere Field is counted as Duel Field as used in the WDC finals match between Yuma Tsukumo and Vetrix on top of the Duel Tower.
- The Duel Fields can be compared to the "Speed World" from the 5D's series. Both are activated just before the Duel, and are treated as Field Spell Cards, but are not actually in any player's Deck.
