Tetris

Tetris (Russian: Ð¢ÐµÑ‚рис)^[a] is a puzzle video game created in 1985 by Alexey Pajitnov, a Soviet software engineer. In Tetris, falling tetrominoshapes must be neatly sorted into a pile; once a horizontal line of the game board is filled in, it disappears, granting points and preventing the pile from overflowing. Over 200 versions of Tetris have been published by numerous companies on more than 65 platforms, often with altered game mechanics, some of which have become standard over time. To date, these versions of Tetriscollectively serve as the second-best-selling video game series with over 520 million sales, mostly on mobile devices.

I never knew it was Russian.
