Tetris was created in 1984 by Soviet programmer Alexey Pajitnov, and its best-known melody is Korobeiniki, a 19th-century Russian folk song about a peddler and a young woman. The tune was arranged as the main theme for the 1989 Game Boy version, which sold millions and carried the music into homes around the world. From arcade cabinets to phone ringtones, remixes and TikTok edits, the melody became shorthand for the game itself, and it still signals fast, addictive puzzle play today.
