Tetris Effect was developed by Monstars and Resonair, with Tetsuya Mizuguchi as a co-producer, and first released for PlayStation 4 and PlayStation VR on 9 November 2018. It reached Meta Quest on 14 May 2020. The Connected update, which added cooperative and competitive multiplayer, arrived on Quest as a free expansion in August 2021. The game takes its name from the "Tetris effect", where people who play for a long time keep seeing falling blocks when they close their eyes.

The rules are classic Tetris, but the presentation is not. The game has thirty themed stages, each with its own music and visuals, and your moves are tied to the beat. A Zone mechanic lets you pause time and clear more than four lines at once, something standard Tetris does not allow. It was very well reviewed, with Metacritic scores from 80 to 94 across platforms, and won Best VR/AR Game at the 2018 Game Critics Awards. On the Meta store it is rated 4.5 from about 2,000 ratings and is rated for everyone.
