Monopoly is a multiplayer economics-themed board game. In the game, players roll two dice to move around the game board, buying and trading properties and developing them with houses and hotels. Players collect rent from their opponents and aim to drive them into bankruptcy. Money can also be gained or lost through Chance and Community Chest cards and tax squares. Players receive a salary every time they pass "Go" and can end up in jail, from which they cannot move until they have met one of three conditions. House rules, hundreds of different editions, many spin-offs, and related media exist. Monopoly has become a part of international popular culture, having been licensed locally in more than 103 countries and printed in more than 37 languages. As of 2015, it was estimated that the game had sold 275 million copies worldwide. The original game was based on locations in Atlantic City, New Jersey, United States with the exception of Marven Gardens which is in adjacent Ventnor, NJ.

Charles Brace Darrow was an American board game designer who is credited as the inventor of the board game Monopoly. Although the original idea for the game came from Lizzie Magie's The Landlord's Game, Darrow has been credited as the creator by Parker Brothers, the game's publisher.
