Tetris 99 has featured a handful of other Switch games for its Maximus Cups, but now the frenetic puzzler will be the star of its own crossover event. Nintendo has announced Super Smash Bros. Ultimate's next Spirit Board event will be based on Tetris 99, and it will introduce a handful of new Tetrimino Spirits to the game.

The Spirit Board event kicks off at 11 PM PT on October 24 and runs through October 29. During that time, the following five new Spirits will appear periodically on the Spirit Board, and you'll receive extra gold for defeating them.

• I-Tetrimino
• L-Tetrimino & J-Tetrimino
• S-Tetrimino & Z-Tetrimino
• T-Tetrimino
• O-Tetrimino

The Spirit Board event will overlap with Tetris 99's eighth Maximus Cup, which runs from October 25-28 and features a new theme based on the upcoming Luigi's Mansion 3. Players will be able to unlock the special theme by amassing at least 100 points by the end of the event. Previous Tetris 99 events have featured themes based on Fire Emblem: Three Houses, Super Kirby Clash, and Splatoon 2.

As for Super Smash Bros. Ultimate, the game's latest DLC character, the bear and bird duo Banjo-Kazooie, arrived last month alongside a Mii Fighter costume of Sans from Undertale. The next add-on fighter will be Terry Bogard from Fatal Fury, and he's slated to join the roster sometime in November.

One more as-yet unannounced fighter remains in Smash Ultimate's Fighters Pass, but that won't be the end of the game's DLC. During its big September 2019 Direct, Nintendo announced that even more DLC fighters will be added to Smash Bros. Ultimate in the future, although the company hasn't shared any more details beyond that.
