The player must defeat each character in every stage five times to advance to the next stage. Once the player beats a character 5 times, he or she may continue to duel them for more points. Here are the list of characters that a player may duel against:
The player's Starter Deck is chosen randomly from the following list of cards:
Yu-Gi-Oh! Duel Monsters features 365 cards, with the last 15 cards being secret. The basic rules differ greatly from the , and are generally simpler.
There are 315 Normal Monsters (from number 001 to 300, and from 351 to 365) and 50 Spell Cards (from number 301 to 350) in the game; these are the only types of cards featured.
While there are no Fusion Monsters, fusions can be performed by trying to summon a monster from the hand on top of a monster on the field (e.g. " Ansatsu" + " Darkfire Dragon" = " Flame Swordsman").
Monsters only have an " Blue-Eyes White Dragon" ATK, DEF, Type, and description. Levels, Attributes, and Alignments are not featured in Yu-Gi-Oh! Duel Monsters, and monsters can be summoned without tributing.
There is no Deck Cost and no limit to the number of copies of one card which can be in a Deck, but the Deck must contain exactly 40 cards and the player can only have one Deck at a time.
Both Duelists' hands consist of five cards.
Each turn has the same layout:
The turn player draws a card.
The turn player must play one card from their hand. If their hand is empty, the Duel ends and the Duelist with higher Life Points wins. Only one card can be played from the hand each turn.
The turn player must attack or switch to Defense Position each monster on their side of the field.
The turn ends.
The player always goes first in a Duel, but does not draw a card and cannot attack on the first turn.
Attacking Battle screen showing " Sangan" attacking " Ancient Jar". works the same as it does in the OCG and .
If the attack target is in Attack Position:
If the monsters have different ATK, the monster with the lowest ATK is destroyed and its controller takes battle damage equal to the difference.
If the monsters have equal ATK, both monsters are destroyed and neither Duelist takes battle damage.
If the attack target is in Defense Position:
If the attack target's DEF is greater than the attacker's ATK, neither monster is destroyed and the attacking monster's controller takes battle damage equal to the difference.
If the attack target's DEF is lower than the attacker's ATK, the attack target is destroyed and its controller does not take battle damage.
If the attack target's DEF equals the attacker's ATK, neither monster is destroyed and neither Duelist takes battle damage.
If the opponent has no monsters, the turn player can attack the opponent directly. In this case, the opponent takes battle damage equal to the attacking monster's ATK.
The player receives a card after every win or draw. After 10 wins or draws against the same opponent, the player receives a second card.
Each copy of
Yu-Gi-Oh! Duel Monsters came with three cards randomly selected from the following set of ten cards:
