When you start the game, you have seven slots in your E-Mail that can be filled so that you can challenge people whenever you want.
Those slots belong to:
Jaden
Syrus
Chumly
Zane
Alexis
Chazz
Bastion

Here's how to get them all:

Jaden, Syrus, and Chumly: Simply, when the game starts, you'll be taken to the Slifer Red dorm where you'll meet Jaden Syrus and Chumly. After a brief chat, you'll get all three addresses.

Bastion: Also easy. When you finally get to your first day, go to the Ra Yellow dorm when there's a question mark to meet Bastion. He'll give you his E-Mail after a short chat.

Alexis: A little more difficult. Wait until durring the week, you hear some Obilisk Blue students talking about someone sneaking near the girl's dorm at night. At night on a weekend after hearing this chat, go to the girl's dorm to find Alexis and her two friends. They'll confront you and all challenge you to a duel, thinking that you;re the perv. You may be able to lose, but I did it by beating all three of them. Once they're done, Alexis will give you her E-Mail.

Chazz: Be a Ra Yellow and defeat Chazz 10 times. Durring the week, Crawler will tell you that you will have a duel with Chazz because you beat him so many times. Defeat him, and you'll be promoted to Obilisk Blue, regardless of your rank, and be allowed to skip the next exam! Chazz will disappear for a while before returning under the wing of another school, and you'll fight him in a duel for a tournament. Defeat him for the three ojama cards, Ojama Delta Hurricane, Ojama Trio, and his E-Mail.

Zane: Wait until you get an E-Mail talking about Syrus hanging out near the river in the morning. When he's at the river in the morning, go talk to him, and you'll be pulled into an unrefusable duel. After the first draw, it will say: "A few turns later" and syrus will draw a card, and tell you a story about Power Bond. After that, he'll use Polymerization to make Steam Gyroid and attack you directly. On your turn, use Polymerization (You'll always have the same hand, regardless of your deck) to make Elemental Hero Thunder Giant, use his ability to destroy Steam Gyroid, and attack Syrus directly. After the duel, Zane will appear, and challenge you to a duel the next day. When that day comes, duel Zane. Whether you win or lose, you'll get Zane's E-Mail.

Happy dueling!

If you have a real Yu-Gi-Oh! Card that you want to obtain in the game, just look at the bottom left of your card, there, you will see the card's number and type it in-game, but if you don't have the card you wanted, just search the card's picture on the internet then look at the bottom left part.

Note: Not all card numbers are accepted in the game especially the new released ones.

To get the sacred beats in the game you must beat the game 99 percent then you duel the chancelor.
