Apparently an official Japanese Pokémon Twitter account called @Poke_times has been holding an event involving everyone's new favorite character: Ball Guy! Part of this event is a trio of Mystery Gift Codes that each give you one each of three rare Pokéballs. Only two of the three codes have been revealed so far, with the final code slated to be revealed after the Japanese hashtag #ボールガイチャレンジ reaches 100,000 Tweets. The codes are: K0UN 1NMA SC0T: Moon Ball, Fast Ball and Level Ball 1YAH AYA: Heavy Ball, Lure Ball and Beast Ball 0KUG AFUK 1B0R U: Dream Ball, Love Ball and Friend Ball I've already used both of the revealed codes in my own American copy of the game, indicating that they are not region-specific and all players should be able to use them without issue.
