A Battle Royal (バトル・ロイヤル, Batoru Roiyaru) is a game of Duel Monsters involving more than 2 sides.
The rules of a normal Duel apply, but a number of changes are made to accommodate multiple players. The following characteristics are common in this kind of Duel:
- Each player is each other player's opponent.
- Players may help or attack other players.
- Players may cooperate against other players.
- No player may attack on their first turn.
- In Yu-Gi-Oh! ARC-V, no player may draw on their first turn either.
- In Yu-Gi-Oh! ARC-V, if a player joins an ongoing duel without themselves dueling in progress, their starting LP is halved to 2000 as a penalty. Called "Intrusion Penalty"
- If they are dueling each other, they can change their current duel into a Battle Royal if they intruded and the other pair agreed.
This type of game has been carried out multiple times in the anime and manga series.
From episode 106 to episode 107, Nesbitt Duels Tristan Taylor, Duke Devlin and Serenity Wheeler at once. Despite the fact that Tristan lost, his cards were still on the field and their effects were still applying.
In episode 165, Valon Duels Rebecca Hawkins and Duke Devlin while using the Battle Royal rules.
In episode 62 to episode 64, Rex Goodwin Duels Yusei Fudo, Jack Atlas and Crow Hogan, with Goodwin starting with 12,000 LP. It is also a Turbo Duel, even though Goodwin doesn't ride a Duel Runner and stands on the top of a temple, but he uses the Turbo Duel rules against his opponents.
In episode 48, a 7-vs-3 (including Reed and Trout) Battle Royal began in the Volcano Area.
In Yu-Gi-Oh! 5D's World Championship 2011: Over the Nexus, Primo unleashes the Diablo army, which attack the player in a fashion similar to the anime. However, instead of engaging in a free-for-all Duel, the player has to dodge the numerous Ally Salvos launched by the Ghosts for a set time. Afterwards, Battle Royal mode is available in the race simulator.
In Battle Royal mode in the video game, top speed and acceleration of the Duel Runner mean next to nothing. The player must survive for a set 90 seconds while dodging the attacks from Ghosts and picking up any items along the way. Accelerating will only move the player further up the screen, while braking does the opposite. Using a booster will allow the player to temporarily outrun the Ghosts and remain unattacked for a few seconds. Rank is determined not by how long the player survives nor how much the player is damaged, but how many items are picked up along the way.
