Congratulations to our 2019 Winner Joseph Saelee!

The 2020 CTWC will take place at the Portland Retro Gaming Expo August 14-16th at the Oregon Convention Center. We hope to see returning champions Joseph Saelee, Jonas Neubauer, and Harry Hong along with many of the players featured in the award-winning Tetris documentary Ecstasy of Order: The Tetris Masters.

After 10 years of Classic Tetris World Championships, the competition is stronger than ever! Inspired by the historic 1990 Nintendo World Championships, the tournament has brought the love of classic Tetris into the 21st century.

The CTWC format is spreading all over the world!  Be sure to check out the Schedule tab to learn more.
