McDonald's teamed with Hasbro to promote MONOPOLY. The game mimics the game of MONOPOLY. Customers receive tokens with certain menu items purchases. Tokens correspond to a property space on the Monopoly board. and when combined into color-matched properties, the tokens may be redeemed for cash. In a 2006 game the grand prize was awarded for collecting the four railroads. In order to restrict the availability of the top prizes, one property in a set is rare. There are also "instant win" tokens the recipient can redeem for McDonald's food (typically small menu items such as a free hash brown or ice cream sundae), cash or other prizes.
