The online service was discontinued on December 31, 2010, rendering the game unplayable due to its lack of an offline mode. In the original Japanese version of Final Fantasy IX, the minigame was called "Quad Mist," with the name written in English text on the game board. The English localization introduced the name "Tetra Master," which was subsequently used in both Japanese and English versions.
