А знаете ли вы

Have you ever known that tetris was invented in Russia? And it celebrates its 30th anniversary in 2014. I think many of us should congratulate it and be thankful for our "happy childhood".

Russian programmer Alexey Pajitnov released the first version of Tetris (Те́трис in Russian) on June 6, 1984. The game featured seven tetrominos descending from the top of the screen, to form a sort of jigsaw-puzzle stack at the bottom. The game became insanely popular, spreading across the globe in a variety of versions, many of them unauthorized, on all sorts of computer hardware.

Today, the NES (Nintendo Entertainment System) version of Tetris is used in the Classic Tetris World Championships, and attracts top players from around the world—many of whom are roughly the same age as the game itself.
