Yugi, Joey, and the Paradox Brothers' Duel is a Duel which took place during the Yu-Gi-Oh! anime, between Yugi Muto, Joey Wheeler. and Para and Dox, the Paradox Brothers during the Duelist Kingdom arc.
After Yugi Muto and his friends get trapped by Bandit Keith and his goons, the latter of which he left behind after Bonz's loss, Bakura Ryou's Millenium Ring suddenly activates and acts like a dowsing rod, leading the group to the location of Pegasus, since the ring can detect and seek out other Millenium Items, like Pegasus's Millenium Eye. As they head closer, Téa Gardner notices the walls look more manmade. Soon, they discover and enter a strange room and meet the Paradox Brothers, who introduce them as Eliminators. They challenge Yugi and Joey to a tag-team duel, with Joey wagering two of his eight star chips and Yugi wagers four of his six. With this wager, if they win, Yugi and Joey will each have ten star chips and thus enter Pegasus's castle. However, both reveal that one door will lead to the way out and the other will lead to an endless labyrinth. In addition, while one of the brothers will tell only the truth, the other will tell nothing but lies.
- Note: This duel is the first ever tag-team duel, where a team of two duelists takes on another team of two duelists. Each duelist starts with the normal amount of Life Points and if one duelist loses all their life points, the other duelist loses alongside them.
Para → Joey → Dox → Yugi.
He also explains the rules of the Labyrinth Duel, where each duelist moves a monster a number of spaces equal to their level. Penguin Knight and The Wicked Worm Beast are used as examples to illustrate how it works.

Joey tries to have "Axe Raider" and "Flame Swordsman" regroup with "Celtic Guardian" and "Dark Magician", but Joey's "Axe Raider" steps on the "Jirai Gumo" landmine (ATK: 2100/DEF: 1000), and by negating the boost from Kunai with Chain, "Axe Raider"'s ATK returns to normal and is destroyed. (Joey LP: 2000 → 1600).
Turn 14: Yugi
Draws a card. Yami Yugi plays Mystic Box, sealing Dark Magician in a box and skewers it with swords, but a second box materializes around Jirai Gumo.

Turn 20: Joey
Draws a card. Joey's removes Flame Swordsman from the hats, however he plays the Magic card Salamandra, increasing the power of Flame Swordsman (ATK: 1800 → 2500). Joey attacks Dungeon Worm and destroys it due to it's weakness to fire negating the bonus from Monster Tamer (Dox LP: 1900 → 1600).

Turn 26: Yugi
Draws a card. Yami Yugi summons Summoned Skull and has it attack Suijin using the trail of water left by the flood to bypass the labyrinth. When Dox tries to activate Kazejin's ability to block attacks, Yami Yugi reveals that when Dox attacked with Suijin, he activated Yami's trap, Spellbinding Circle, which not only holds the Gate Guardian in place but lowers each sections ATK.

Turn 29: Dox

- Yami Yugi LP: (800 → 400)
- Joey LP: (1300 → 650)
- Sanga of the Thunder: (ATK: 2600 → 3000)
- Kazejin: (ATK: 2400 → 3050)
Dox, however, cannot attack on the turn he plays Riryoku, so he ends his turn.
Turn 30: Yugi
Draws a card. Yami Yugi sets a card, activates Monster Reborn to revive a monster, has Dark Magician move to the end of the maze and ends his turn.
Turn 31: Para
Without checking what monster Yugi revived, Para attacks "Dark Magician" with "Gate Guardian", but Yugi activates the effect of "Suijin" to end the attack, revealing he had revived Suijin.
Turn 32: Joey
Draws a card. Joey draws Copycat and thinks about how to use it since it can copy one card his opponent played. Joey plays Copycat as Riryoku, draining half of Para and Dox's Life Points and adding them to Black Skull Dragon:
- Para LP: (900 → 450)
- Dox LP: (900 → 450)
- Black Skull Dragon: (ATK: 3200 → 4100)
Joey, however, cannot attack so he ends his turn.
Turn 33: Dox
Draws a card. Dox attacks Dark Magician with Sanga of the Thunder but Suijin intercepts the attack, however, he attacks with Kazejin destroying Suijin.
Turn 34: Yugi
Draws a card. Yugi activates "Monster Replace" to switch the positions of his "Dark Magician" and Joey's "B. Skull Dragon". Since it was Fusion Summoned using both his own and Joey's monsters, Yugi takes control of it and attacks "Gate Guardian", destroying both "Sanga of the Thunder" and "Kazejin" (Para and Dox: 450 → 0).
Yami Yugi and Joey win their remaining Star Chips. With ten each, they were allowed entry into Pegasus's Castle, but the Paradox Bros had one more trick up their sleeve. Yugi still had to guess which door would lead them out, so Yugi placed the symbols on two coins, one for Para and one for Dox. Instead of flipping the coins, Yugi placed a coin in each hand. And whichever coin remains clinched will be the door he chooses. When he released the coin with Dox's symbol, they both reveal Dox's door was the way out. However, Yugi outsmarted them both, by showing them that he had the coin with Dox's symbol clinched in his other hand, revealing that the coin with Para's symbol also had Dox's symbol on the other side, since they both like to manipulate the maze and the doors, so Yugi made it so that no matter what, he would always pick Dox's door. The gang finally escape and head to Pegasus's castle.
