Tetris® Effect amplifies the magical feeling of total immersion by surrounding you with fantastic, fully three-dimensional worlds that react and evolve based on how you play.
Music, backgrounds, sounds, special effects—everything, down to the Tetris pieces themselves, pulse, dance, shimmer, and explode in perfect sync with how you're playing, making for a game you'll want to experience over and over for days, weeks, and months. The core of the game is still Tetris—one of the most popular puzzle games of all time—but like you've never seen it, or heard it, or felt it before.
Whether in full HD on a standard display with a PlayStation®4 system, or in razor-sharp 4K resolution with a PlayStation®4 Pro system, or in fully-immersive 3D via the optional PlayStation®VR support, Tetris® Effect's gorgeous imagery, evocative sounds, and engaging gameplay add up to an unforgettable experience.
Not at the moment, but they will be updating it around the launch of the PS5 with more modes. There are some online leaderboards and things but nothing competitive. Still VERY worth the money, farastic game. Its the same ol Tetris. Just reinvented. Hope this helps!
You would have more fun trying to figure it out then actually playing the game.
