About CTWC

The Classic Tetris World Championship (CTWC) began in 2010 where the first ever Classic Tetris World Champion was crowned.

Now in its 16th year, the CTWC has evolved from a grassroots tournament into a global esports phenomenon-garnering millions of views on its YouTube and Twitch channels.

A few of our highlights…

We have been running competitive Tetris tournaments across the world for over a decade. Here are just a few of our achievements over the years.

Over $100,000 in prize money

Our prize pools continue to grow each year, with thousands being awarded each CTWC to our players, as well as several other prize pools from regional and online events.
