As is usually the case when Nintendo releases big titles for Switch, they also have a matching Maximus Cup in Tetris 99 where skilled Tetris players can unlock various goodies such as music, themes and Tetriminos with design based on the current game.
Since Princess Peach: Showtime has now launched, they've announced a new Maximus Cup - the 39th edition, so we're guessing the next cup will be a mini-anniversary - which starts this Friday and lasts all weekend. As long as you subscribe to Switch Online, it's free to participate, so be sure to try and win some goodies.
Check out what it looks like in the X post below.
