Tetris, released in 1984 by Soviet programmer Alexey Pajitnov in Moscow, became one of the most commercially successful video games in history. The puzzle game features falling tetrominoes—four-block shapes—that players rotate and position to form complete horizontal lines, which then disappear from the playing field.
Pajitnov created Tetris while working at the Academy of Sciences of the Soviet Union. The game was first distributed on Electronika 60 computers throughout the Soviet Union before reaching Western markets. Nintendo released the Game Boy version in 1989, bundling it with the handheld console and selling over 40 million copies worldwide.
In 1999, The Tetris Company was founded to manage licensing and intellectual property. The game received the Video Game Hall of Fame induction in 2016 from The Strong National Museum of Play in Rochester, New York. Tetris has sold over 100 million copies across all platforms, making it the best-selling video game of all time and defining the puzzle game genre.
