Tetris

Tetris was created by Russian programmer Alexey Pajitnov in June 1984. He had an immense love for puzzles, and he felt compelled to create a game that allowed players to arrange distinctive puzzle pieces along the bottom of a field or "matrix." Pajitnov chose the name Tetris by combining the words "tetromino" and "tennis."


The game was first made available on the IBM computer. It quickly enjoyed popularity and was ported to a variety of other platforms. In 1987, it became a major hit in the United States.


But it wasn't until Nintendo released its version of Tetris for the Game Boy in 1989 that Tetris reached critical mass. According to The Tetris Co., the Game Boy version of Tetris sold more than 35 million copies.
