It's hard to overstate how big of a deal "Tetris" is. From its humble origins in Russia to a worldwide phenomenon that's spanned decades, "Tetris" is one of the most important games ever made.
It's also so, so good.
The concept is immediately clear to anyone playing "Tetris": Clear the board by creating lines using the randomized pieces that are falling from the top. Its raw puzzle nature is more akin to Sudoku or crosswords than most other video games. That simplicity lends itself well to accessibility — "Tetris" will run on nearly any computer or game console. It was just as good on the original NES as it is on a modern game console. And since it's a puzzle game above all else, it stands the test of time.
It's hard to quantify exactly how many copies have been sold of "Tetris."
It's been available on so many platforms across so many years that simply keeping track is difficult. A representative from The Tetris Company — the group that oversees "Tetris" on an ongoing basis — told us the following via email: "Billions of 'Tetris' games are played online every year, and over 500 million 'Tetris' mobile games have been downloaded to date."
"Tetris" is famous for being the best-selling mobile game of all time — a record it achieved way back in 2010, before smartphones were ubiquitous — having sold more than 100 million digital copies at that point already. Our best guess puts the game's lifetime sales somewhere north of 200 million copies sold, but the truth is that it's hard to know for sure.
