History of Tetris:

Tetris is a puzzle video game that was created by Russian software engineer Alexey Pajitnov in 1984. It was released in the Soviet Union on June 6, 1984. The game is based on a simple concept: players must place falling tetrominoes (shapes made up of four squares) into a grid to create complete rows, which then disappear. Pajitnov named the game "Tetris" by combining the Greek prefix "tetra," meaning "four," with "tennis," his favorite sport.

Tetris quickly became popular in the Soviet Union and was later released in other parts of the world, including Japan and the United States. The game has been released on numerous platforms, including arcade games, home video game consoles, and mobile devices. In 1988, Tetris was released for the Nintendo Entertainment System (NES) in North America and quickly became one of the most popular video games of all time. Today, Tetris is available on a wide variety of platforms and has been played by millions of people around the world.
