Risk is a strategy board game produced by Parker Brothers (now a division of Hasbro). It was invented by French film director Albert Lamorisse and originally released in 1957 as La Conquête du Monde ("The Conquest of the World") in France. Risk is a turn-based game for two to six players. The standard version is played on a board depicting a political map of the Earth, divided into forty-two territories, which are grouped into six continents. The object of the game is to occupy every territory on the board and in doing so, eliminate the other players.[1] Players control armies with which they attempt to capture territories from other players, with results determined by dice rolls.

Tetris (Russian: Те́трис, pronounced [ˈtɛtrʲɪs]) is a Soviet tile-matching puzzle video game originally designed and programmed by Alexey Pajitnov. It was released on June 6, 1984, while he was working for the Dorodnicyn Computing Centre of the Academy of Science of the USSR in Moscow. He derived its name from the Greek numerical prefix tetra- (all of the game's pieces contain four segments) and tennis, Pajitnov's favorite sport. It is also the first entertainment software to be exported from the USSR to the US and published by Spectrum HoloByte for Commodore 64 and IBM PC. The Tetris game is a popular use of tetrominoes, the four-element special case of polyominoes. Polyominoes have been used in popular puzzles since at least 1907, and the name was given by the mathematician Solomon W. Golomb in 1953. However, even the enumeration of pentominoes is dated to antiquity. 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, PDAs, Network music players and even as an Easter egg on non-media products like oscilloscopes. It has even inspired Tetris serving dishes and been played on the sides of various buildings. While versions of Tetris were sold for a range of 1980s home computer platforms as well as the arcades, it was the hugely successful handheld version for the Game Boy launched in 1989 that established the game as one of the most popular ever. Electronic Gaming Monthly's 100th issue had Tetris in first place as "Greatest Game of All Time". In 2007, Tetris came in second place in IGN's "100 Greatest Video Games of All Time". In January 2010, it was announced that Tetris had sold more than 170 million copies, approximately 70 million physical copies and over 100 million copies for cell phones, making it the highest paid-downloaded game of all time. On 16 March 2014 Tetris featured in the Sochi 2014 Paralympic Games closing ceremony where a huge colourful game of tetris was played on the stadium floor and the Tetris cubes spelling out the word impossible.
