Players duel using cards, in the same way as in the Yu-Gi-Oh! Trading Card Game. Each player starts with a 40-60 card starter Deck. After that, players need to duel to get more cards. Whenever a single game (1 duel) is played, both players get 1 card from a card pack of their choice. Whenever a match game (2 or 3 duels, first to win twice wins) is played, both players get 3 cards from a card pack of their choice.
There are 30 player Levels, Levels 1 through 30. Once a player has played at least 36 duels, he or she can advance beyond Level 1, and must to move from the beginner's lobby to the other lobbies where all players Level 2 and above play.
The player's Level is decided by their score. Each time a player wins a duel, that player's score increases, and whenever a player loses a duel, their score decreases. The amount of points received or deducted depends on the player's level and the opponent's level. For example, a Level 2 player winning from a Level 5 player would gain more points than a Level 6 player winning from a Level 3 player.
To duel, players must spend Duelpass Points (DP). It costs 1 DP for 1 duel. Duelpass points are obtained by purchasing Duelpasses. Purchasing a Duelpass gains the player 30 Duelpass Points, 1 card in the game, and 10 Mileage (that players can exchange for cards). Ten Duelpass points are given for free to every account when they are first created.
This is an online purchase that is equivalent to 5 Duelpasses (150 Duelpass points). The 5 cards gained from this type of Duelpass are chosen randomly from a set. At one point, sale of the Duelpass 150 was suspended in the United States due to fraud, but since the release of Duel Evolution, the Duelpass 150 is available in United States again.
USB Duelpass Key
The USB Duelpass Key is equivalent to 3 Duelpasses (90 Duelpass points). It is a USB device that is sold in retail stores in the United States, such as Toys 'R' Us and Target. It works like a standard USB flash drive, except it only contains the information necessary to transfer game credits to your account. A CD-ROM with the full version of the game is included in the packaging for the USB Duelpass Key. The flashdrive itself has only 128K or so of memory, unusable for anything but the duel pass credits. The 3 cards gained from this type of duelpass are chosen randomly from a set. The USB Duelpass Key is sold only in the United States and Mexico. Players in other locations must get duelpasses from one of the other methods or buy them from a third party.
The SMS Duelpass is available in the United Kingdom to date and for a charge of £1 you gain 15 Duel Points and 10MP. It's a quick and popular way of obtaining Duel Points.
