Getting Rare Cards
Keep playing until you meet Shadi: defeat him and he will probably give you a rare card. Alternatively, defeat Bandit Keith, who gives you an Exodia.
Super Rare Card
To get it you need 9,999 star chips. Then type the password 89631139 in the password area and press "Exchange".
3D Battle Arena
Press X on one of your monsters, then press Square instead of X to make it attack again.
Crossing the Labyrinth
After defeating the labyrinth guardian you are asked which way to go: go right, right, left, right. Seto and Heishin will appear and you can duel Seto.
