The beloved video game Tetris has a fascinating, complicated history. While the Tetris Company (TTC) claims exclusive rights to the geometric pieces at the heart of the game, known as tetrominoes, history shows that the Russian engineer and game designer duo behind TTC did not, in fact, own them. In this excerpt of Soviet Blocks: The Bizarre Puzzle of How Tetris Embraced Western Values, Julien Mailland traces Tetris’s journey from the Soviet Union to the West, and shows how the game is a lens through which to view two very different systems.

After the Soviet Union collapsed, Belikov and Patjinov — who by then had teamed up with Nintendo’s fixer Henk Rogers — sued each other over the rights to the game in federal court in New York. Pajitnov had very little going for him. The USSR did not recognize software copyright, or any private property for that matter other than for household pots and pans. Further, he developed the game on his work computer during work hours, which under U.S. legal principles would make it his employer’s property.
