In Yu-Gi-Oh! Duel Monsters International 2 and Yu-Gi-Oh! 7 Trials to Glory: World Championship Tournament 2005, the player can unlock Mai as an opponent, by winning the weekend tournament a certain number of times. The player can then Duel her near the shopping district on Mondays and Saturdays, at the K.C. Tower on Tuesdays and Thursdays, in the hometown on Wednesdays and at the Coliseum on Fridays and Sundays. She also faces the player in the K.C. Tower Tournament, the Limitation Tournament, in which the player cannot use WIND monsters, and is a potential round two opponent in the Sugoroku Tournament. When the message "Are the Harpie-related cards for Mai only?" appears on the player's screen, they can challenge Mai to a special Duel, if they have no Spell or "Harpie" cards. The special Duel takes place in the Mountain terrain. If Mai wins, she takes one of the player's "Harpie Lady" cards. If the player wins, they get 1000 DP and cards from the Super Monster Collection Pack.
