The promotion mimics the game "Monopoly". The game is also advertised with tokens appearing in Sunday newspapers. Originally, customers received a set of two tokens with every purchase, but now tokens come only with certain menu items. Tokens correspond to a property space on the Monopoly board (with the exception of the "Golden Avenue/Arches Avenue" "properties", which were added in the 2008 edition; and "Electric Company/Water Works" utilities added in 2014). When combined into color-matched properties, the tokens may be redeemed for money. Historically, the grand prize ($1 million, annuity only) has been the combination of the two most costly properties, Park Place and Boardwalk, but in the 2006–2007 games the top prize ($5 million, with the traditional $1 million prize for Boardwalk/Park Place) was awarded for collecting the four railroads.
