Community Chest is based on the game Monopoly and is a smaller version of the game. You play the computer and try to make money without going bankrupt. The game has 16 squares with 13 squares named after London streets, Community Chance, Jail and a Go square. The street squares are split into six sets. Each player takes it in turns to throw a dice to move their counter and if a street square is landed on then the player has a choice to buy it if the player has enough money. If the player has brought a street to make up a set then houses can be brought and placed on the square. As the players move buying streets and a player lands on a street square owned by the other player then that player has to pay rent and the cost depends on how expensive the street is and if there are any houses on it. Landing on a Community Chance square reveals an incident and this can either lose or gain the player money. The Jail square forces the player to pay a fee and if a player passes the Go square then they receive £2000. A player will lose the game if they go bankrupt.
