Yu-Gi-Oh! The Sacred Cards known as Yu-Gi-Oh! Duel Monsters 7: The Duelcity Legend in Japan, is an RPG-style game for the Game Boy Advance.

The story of the game loosely followed the Battle City story arc of the anime and manga, with adjustments to allow the player to act the part of a major character and participate all the way into the Battle City Finals.

One important thing to note is that the game automatically cuts to the ending sequence immediately after the defeat of Marik Ishtar, with no option to save. Because of this, any money or rare cards earned in the final duel are irrelevant, and the player never has an opportunity to use The Winged Dragon of Ra without the use of a game-hacking device. The only way to do this normally is to allow Marik to Summon Ra and destroy it (or somehow discard it from the hand), then Special Summon it from the graveyard. Also noticeable that even in the English version of the game, most of the cards have their original OCG artworks like Soul of the Pure, Monster Reborn and Last Day of Witch.

A Konami 'cameo' in this game is the Miracle Moon music in the arcade, which is taken from the Beatmania series of games.
