Monopoly is derived from The Landlord's Game, created by Lizzie Magie in the United States in 1903 as a way to demonstrate that an economy that rewards individuals is better than one where monopolies hold all the wealth and to promote the economic theories of Henry George-in particular, his ideas about taxation. The original game was based on locations in Atlantic City, New Jersey, United States. As of 2015, it was estimated that the game had sold 275 million copies worldwide. 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. House rules, hundreds of different editions, many spin-offs, and related media exist. 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. Money can also be gained or lost through Chance and Community Chest cards and tax squares. Players collect rent from their opponents and aim to drive them into bankruptcy. In the game, players roll two dice to move around the game board, buying and trading properties and developing them with houses and hotels. Monopoly is a multiplayer economics-themed board game.
