Alex T
Alex Thach (born November 7, 2008), known online as Alex T, is an American classic Tetris player. He is best known for back-to-back victories in the 2024 and 2025 Classic Tetris World Championships (CTWC), becoming the first person to get a score of over 10 million points, and achieving various other records on both original and modified game cartridges which prevent crashes late game.
Thach entered the competitive Tetris scene in 2020 at 11 years old. He initially found success using the "hypertapping" technique of playing but in 2022 adopted the more competitive "rolling" technique as competition improved. Using the new technique, Thach broke multiple records in a more than hour-long game livestreamed on March 11, 2024, where he achieved the highest level reached in one game and a score of more than 10 million, also winning a $2,600 bounty made by the Tetris community for being the first to do so. On June 9, 2024, Thach won the CTWC after beating two-time former champion Michael Artiaga (known online as "Dogplayingtetris"). On June 9, 2025, Thach became champion again, this time without losing a single game: breaking several records in qualifying and bracket play.
Upon his back-to-back CTWC victories, Thach has been described as the "greatest Tetris player in the world" in a 2025 interview by The Classic W. Thach has also remained in Tetris pop culture by featuring in Guinness World Records, on game shows, and through his signature victory celebration of dumping parmesan cheese on his head.
