Duel Coaster

The Duel Coaster (デュエル・コースター, Dyueru Kōsutā) is a special kind of roller coaster in the Yu-Gi-Oh! ZEXAL anime. It is the site of the WDC Finals, similar to the concept of Kaiba Craft 3, being a mobile spot of the Battle City finals that takes place over the city. The finalists of the World Duel Carnival are to use it as a method to determine whom they will face in the preliminaries of the tournament. It appears that the duels operate in a Battle Royal mode, where any duelist can challenge another they meet, as well as gang up for combination attacks against a single opponent. Players can Summon monsters in Face-up Defense Position. Players can dodge attacks if they change lanes (similar to in the Yu-Gi-Oh 5D's Manga where players can dodge their opponent's attacks during a Turbo Duel).

When a duelist's Life Points hit zero, they are ejected from their car and parachuted down. The empty car is switched to a different track and the winner continues on.

There are special spots on the track, with Spell and Trap Card markings. If a duelist goes over one of these spots, they will activate the card's effect. This could either be good or bad: good, in the case of V when he found "Dian Keto the Cure Master" and gained 1000 Life Points, or bad, in the case of Yuma Tsukumo, who found "Secret Barrel" and lost 1000 Life Points. Life Points don't seem to reset every time there's a new duel, as V found "Dian Keto the Cure Master" after he won his first duel. As such, skills such as handling Speed, keeping track of which lanes your opponents are in, and keeping in mind the cards set along the track, add for a much more unpredictable Duel style.

So far, it seems that Spell Cards give life points, while Trap Cards inflict damage. This incorporates a new element of luck and strategy, as one could be on the verge of defeat but can also find themselves revived or unexpectedly defeated.

A complete set of Heart Pieces is the starting key for each duelist's coaster.

Additional rules were shown in episode 52, specifically that duels are not carried out with the normal rules of Duel Monsters. Though a player can only perform one Normal Summon during their turn, there is no specific turn count on the Duel Coaster. A player can draw, summon a monster, and battle with it but the opponents can also do that during another player's turn.

A player can only attack a player that is on the same lane and can avoid the Duel entirely by moving to another lane. The opposite is also applied since a player can resume a Duel by moving back to the same lane as the opponent's. Also, a player can use their allies' monsters for an Xyz Summon.
