Mix the calming waters of Endless Ocean Luminous with the frantic gameplay of online Tetris matches and you have an ocean of confused sea critters, or the potential for a new theme on your copy of Tetris 99.

Starting next weekend, May 10th to May 13th, is the 40th MAXIMUS CUP. As always, earn points depending on how well you perform in each online match. If you accumulate 100 points throughout the weekend, you unlock the theme to keep forever.

This theme features art, music and themed Tetris blocks from the world of Endless Ocean Luminous.

Tetris 99 is a free download as part of your Nintendo Switch Online subscription.
