[*]Participants must have a ranking of at least five out of eight stars (manga) or level four out of five (anime) to receive a free
Duel Disk, which is required to participate.
[*]Players must play with a
Deck of at least forty cards.
[1]
[*]Players begin with 4000
Life Points.
[*]Players can only have up to 6 cards in his or her
hand unless the card "
Infinite Cards" is in play on his/her side of the field.
[2]
[*]One
Normal Summon is allowed per player per turn.
Monsters can be Summoned in
face-up Attack Position, face-up
Defense Position or
face-down Defense Position.
[*]
Level 4 or below monsters can be Summoned during a Normal Summon.
[*]Level 5-6 monsters needed one
Tribute in order to Normal Summon.
[*]Level 7-9 monsters required two Tributes to Normal Summon.
[*]Level 10+ monsters required three
Tributes to normal summon (e.g "
The Winged Dragon of Ra", Level 10).
[*]When a
Fusion Monster is Tributed, that monster is counted as a number of monsters equal to the number of
Fusion Material Monsters that were used.
[3]
[*]Fusion Monsters must wait one turn after they are
Summoned before they can attack, though the "
Quick Attack" card can be used to circumvent this.
[4]
[*]If an opponent had no monsters in play, the Turn Player is free to attack his/her
Life Points directly, reducing their total by the monster's
ATK value.
[*]Each player must
ante at least their rarest card and a minimum of one Locator Card in their possession. The winner of the duel obtains their opponent's ante'd rarest card and Locator Card as wagered.
[*]The contents of either player's
Graveyards are not open knowledge, and an opponent may not look through their opponent's Graveyard.
[*]If you have to
discard cards from your hand or Deck, you do not have to show them to your opponent.
[*]You must stick to the tournament's list of
forbidden and
limited cards. Cards that inflict
Effect Damage to the opponent's
Life Points, such as "
Hinotama" and "
Meteor of Destruction", were forbidden.
[5] Only one copy of "
Monster Reborn" could be included in one's Deck.
[6]
[*]Certain cards that enabled players to
Special Summon monster(s) can affect both sides of the field ("
Dark Magic Curtain" and "
The Flute of Summoning Dragon", for example).
[7][8]
[*]Players were not allowed to use two or more
Magic Cards of the same name that increase a card's ATK points within the same turn.
[9]
[*]In the manga, the opponent can activate a card or card effect before the Turn Player draws a card.
[*]If a monster is offered as a Tribute by the effect of another card while being attacked by an opponent's monster, the enemy's attack is
negated. The Japanese version of the anime calls this rule, "Sacrifice Escape".
[*]
Replays are not an established mechanic. If a monster is played during the battle phase the attack is intercepted by that monster if their field is empty.
[*]Players can set
Field Spell Cards in their
Spell & Trap Card Zones but when they activate them, they get moved to the
Field Card Zone.
[*]Players could activate cards before a player makes a specific move. "
Time Seal", for instance, could be activated before the opponent drew a card.
[*]Some cards had the reverse display instructions the
OCG/

Lightforce Sword" revealed the card it removed from play.
[*]Field Spell Cards can be activated during the Battle Phase.
[*]A non-Quick Play Spell Card can be activated during the Battle Phase.
[*]A non-Quick Play Spell Card can be activated during your opponent's turn if it was set.
[*]Any card that a player uses will be sent to their Graveyard after they are resolved, Tributed, sent to the Graveyard, or destroyed even if the player was not the owner of that card.
[*]When a Spell or Trap is destroyed by a card effect, it is negated even if the card that destroyed the Spell/Trap doesn't negate its effects.
[*]A monster that becomes an Equip Card is treated as both a monster and an Equip Card.
[*]Effects that require the player and the opponent to have cards in their hand can be activated even if one of the players has no cards in their hand.
