Tetris is a puzzling game in which players have to arrange different "falling" block pieces along the bottom side such that every dot in the matrix get filled up in order to clear the line. It is one of the most widely recognized evergreen video games, with mass worldwide appeal that continues to thrive.

Since its creation 25 years ago, the game is still provided pre-loaded in many new mobile handsets. But not limited to just cellphones, this game is available for nearly every video game console and PCs, as well as on devices such as graphing calculators, media players, PDAs and even as an Easter egg on non-media products like oscilloscopes. The company claims that till date more than 125 million Tetris products have been sold.

Researchers say that playing of tetris boosts general cognitive functions such as "critical thinking, reasoning, language and processing" and increases cerebral cortex thickness. Possibly because of this, my roommate is very fond of this game, and has successfully infected more than a dozen in his circle.

Apart from regular additions of attractive new features in latest version of the game, its first ever released version in 1989 is nowhere lags than the latest one. That's why the company has made it available to freely enjoy the very first release of the game for Tetris lovers.
