Yu-Gi-Oh! Online features all the cards and rules of the popular trading card game, and allows players to compete and trade cards via a simple point'n'click interface. To facilitate online play, Konami uses a novel charge-based 'DuelPass' system, sold in stores worldwide.
A 16-digit code is printed on each DuelPass. On entering the code, players can unlock the card featuring the figure that appears on that DuelPass card in the game and add it to their deck of cards. Users receive 30 points with one DuelPass, and one point is good for one duel.
