The monster card Giant Orc is named "Giant Oak". Additionally, when viewing the monster
card Dark Magician, it describes it as the ultimate wizard in terms of attack and
"didense" instead of "defense".

Go up to the dog or cat and press R. Although it seems that you cannot challenge him, you
can.

Sometimes when you are dueling Yugi Muto, he will summon all Dark Magicians from his hand,
and summon ones outside the duel until he has five on the field at the start of the duel.
If you win, you gain 2,500 DP.

Obtain 100 DP to unlock the Weekend Tournament.

If you draw all five pieces of Exodia, but then have to toss away a piece due to a card
effect, the Exodia sequence plays and the game ends in a draw (such as when you have three
pieces and you use Graceful Charity - at one point you have all five pieces in the hand,
but you only have four after the effect).

If you challenge someone to a duel, you must play rock, paper, scissors. If you lose,
rapidly continue to press L and you will go first.

When you battle Yugi, he is able to ritual summon Black Luster Soldier without tributing
any monsters for it. He has at least two of them that he can throw onto the field easily.
