Tetris is a falling-blocks puzzle video game, released on a vast spectrum of platforms. Alexey Pajitnov originally designed and programmed the game in June 1985, while working for the Dorodnicyn Computing Centre of the Academy of Science of the USSR in Moscow. Pajitnov has cited pentominoes as a source of inspiration for the game. He derived its name from the Greek numerical prefix "tetra-", as all of the pieces contain four segments, and tennis, Pajitnov's favorite sport.

The game (or one of its many variants) is available for nearly every video game console and computer operating system, as well as on devices such as graphing calculators, mobile phones, portable media players, and PDAs. It has even been played on the sides of various buildings, with the record holder for the world's largest fully functional game of Tetris being an effort by Dutch students in 1995 that lit up all 15 floors of the Electrical Engineering department at Delft University of Technology.

While versions of Tetris were sold for a range of 1980s home computer platforms, it was the hugely successful handheld version for the Game Boy launched in 1989 that established the reputation of the game as one of the most popular ever. In 2007, Tetris came in second place in IGN's 100 Greatest Video Games of All Time.

Use your arrow keys to move the pieces left and right. The up arrow rotates the piece. The down arrow moves the piece down one line quickly. The spacebar is for drop... and it does!
