Alex Thach (born November 7, 2008), known online as Alex T, is an American classic Tetris player. He is best known for his victory in the 2024 Classic Tetris World Championships (CTWC), becoming the first person to get a score of over 10 million points, and a number of other smaller records achieved 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 originally 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 $2,400 bounty made by the Tetris community for being the first to do so. On June 9, 2024, Thach won the Classic Tetris World Championship (CTWC) after beating two-time former champion Michael Artiaga ("dogplayingtetris"). Thach is also known for his unique and signature victory celebration of dumping Parmesan cheese on his head.
