Tetris 99 may be a few years old, but the game is still supported, even today. When the game doesn’t have the occasional Maximus Cup, there are sometimes brand new updates to the game. The last time an update was released was about a year ago.
Well, Nintendo decided to release a new update tonight. When you update Tetris 99, the game should be version 2.3.0. As for the patch notes, since the update is small, I won’t say much. All they say is that “several issues have been fixed to improve the gaming experience”.
