Monopoly is a board game published by Parker Brothers, a subsidiary of Hasbro. Players compete to acquire wealth through stylized economic activity involving the buying, renting, and trading of properties using play money, as players take turns moving around the board according to the roll of the dice. The object of the game is to own every piece of property and drive the other players into bankruptcy. The game is named after the economic concept of monopoly, the domination of a market by a single entity.
In fact, tournament play calls for a 90-minute time limit. 2 hour time limits are used for international play.
