Nintendo's Super Mario 35th anniversary celebration continues this week with a new event in Tetris 99. The online puzzler's 18th Maximus Cup kicks off on December 3, and this time around, players will have a chance to unlock a theme based on the classic SNES collection Super Mario All-Stars.

Like previous Maximus Cups, this week's event is a point-based competition. Players will earn a different amount of points depending on how well they place in a round. If you can amass at least 100 points before the Maximus Cup ends, you'll unlock the Super Mario All-Stars theme for the game. You can get a glimpse at that theme in action below.

The Maximus Cup runs until 10:59 PM PT on December 7 (1:59 AM ET on December 8). As usual, you'll need to have a Nintendo Switch Online subscription to participate in the event. An individual membership costs $4 for one month, $8 for three months, and $20 for one year, while an annual Family Plan costs $35 and covers up to eight Nintendo Accounts.
