Yu-Gi-Oh Millennium Duels

You only need to complete one duel for this achievement and it doesn't matter if you win or lose. Therefore, the quickest way to do this will actually be choosing to surrender. From the main menu, pick Single Player. Press A several times as you go through the ladders and sub-ladders until it goes to the first match details where you face the opponent "Tea Gardner". Press A again to confirm and then select any deck since this part doesn't matter. Once in the match, there will be a quick round of rock-paper-scissors to determine who goes first. After this and when it is your turn, click on the deck of cards to your right that are face down. After the finger cursor icon is pointing at the deck of cards, press A and then press A again to choose the option "Surrender". It will prompt you "Do you surrender?" so choose Yes and click A once more. You will lose the match but it will count as one complete duel and your achievement will pop!
