Alexey Pajitnov immigrated to the United States, marking a significant turning point in his life and career. This move allowed him to pursue opportunities in the Western gaming industry and eventually gain financial control over Tetris.

The Soviet Union officially dissolved, marking a significant geopolitical shift and the end of the communist state under which Tetris was created. This event indirectly influenced Pajitnov's ability to secure royalties from Tetris, as it led to his move to the United States.

Tetris was licensed to Andromeda Software by ELORG for distribution in the West and was distributed by Mirrorsoft in Europe and Spectrum Holobyte in the United States, marking a significant step in the game's global recognition and popularity.

Alexey Pajitnov completed the first playable version of Tetris while working at the Dorodnitsyn Computing Centre in Moscow. This initial version lacked levels and a scoring system but proved highly addictive, signaling the game's potential.

Dmitri Pavlovsky wrote a program Peremoga, based on graphics capabilities of new equipment. This program inspired Alexey Pajitnov to create a game, which later became known as Tetris. Peremoga featured falling geometric shapes that the player had to rearrange.
