Which country did Tetris originate in?

Tetris originated in the Soviet Union.

Alexey Pajitnov created the first version of Tetris in the mid-1980s while working as a computer researcher in Moscow. At the time, Moscow was part of the Soviet Union, and the game was developed on an Elektronika 60 computer used at the Soviet Academy of Sciences’ computing center.

The game spread informally through Soviet computer circles before reaching Hungary and then the West. Because Soviet state organizations controlled software export and licensing, Tetris’s international release became entangled in a complicated legal and commercial struggle. The state-run organization Elektronorgtechnica, commonly called Elorg, handled the Soviet Union’s licensing arrangements, while Pajitnov initially did not receive royalties from the game.

A common mix-up is answering Russia. Russia is the country most closely associated with Tetris today, and Pajitnov later moved there and then to the United States, but Tetris was created in the Soviet Union before its dissolution in 1991. The game’s famous Russian imagery in Western marketing reinforced that association, but the historically precise origin is Soviet rather than British, American, or Japanese.
