What was the object of the westing game

A mysterious realtor arranges for a specific group of people to become tenants in an apartment building called Sunset Towers that overlooks the abandoned mansion of Samuel Westing. A diverse group of unconnected people, both families and individuals, live together in at the Sunset Towers until a young girl, Turtle, discovers the body of Sam Westing after entering the Westing mansion on a dare. After his body is discovered, the tenants learn that each of them is considered heirs to the Westing fortune and are invited to the mansion to hear the will. Sam Westing's will claims that one of them is the murderer and divides them up into pairs and gives them each clues to solve the mystery of who killed him. The winner will receive 200 million dollars.
