If you haven't beaten the game, the color of the title screen is normally blue. But after you beat the game, the color switches to purple. You can change it back to blue by pressing Up, Up, Down, Down, Left, Right, Left, Right, B, A at the title screen. Input the same code to change it back to purple.

Every Tuesday, the card shop closes. But every other tuesday, you can find Grandpa Yugi wandering around a random area. You can duel him and his exodia deck at that time.

When playing with an Exodia Deck, If your hand contains, for instance, three of the necessary pieces and Graceful Charity, and you activate Graceful Charity, If you get the final two pieces before you have to discard according to Graceful Charity's effect, and you discard Exodia pieces, the animation for an Exodia victory will play, but the match will be considered a Draw. Weird, huh?
