After a limited special-edition release in 1999, in France, called Risk: Édition Napoléon in commemoration of 200th anniversary of the Napoleonic era (1799-1815), a new edition called Risk: 2210 A.D. In 1993, the rules for Secret Mission Risk, which had been the standard in Europe, were added to the United States edition. Called Castle Risk, it featured a map depicting 18th-century European castles instead of a map of the world, and it was a financial disappointment.

The first new version of Risk was released in 1986. It was bought by Parker Brothers and released in 1959 with some modifications to the rules as Risk: The Continental Game, then as Risk: The Game of Global Domination. Risk 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. It is still in production by Hasbro with numerous editions and variants with popular media themes and different rules, including PC software versions, video games, and mobile apps. The simple rules but complex interactions make it appealing to adults, children, and families. Risk was invented in 1957 by Albert Lamorisse, a French filmmaker, and it became one of the most popular board games in history, inspiring other popular games such as Axis & Allies and Settlers of Catan. European versions are structured so that each player has a limited 'secret mission' objective that shortens the game. The game can be lengthy, requiring several hours to multiple days to finish. The goal of the game is to occupy every territory on the board and, in doing so, eliminate the other players. Players may form and dissolve alliances during the course of the game. Turns rotate among players who control armies of playing pieces with which they attempt to capture territories from other players, with results determined by dice rolls. The standard version is played on a board depicting a political map of the world, divided into 42 territories, which are grouped into six continents. Risk is a strategy board game of diplomacy, conflict and conquest for two to six players.
