Monopoly is a popular board game in which players compete to acquire wealth through property ownership and strategic trading. The game requires players to use the six-letter word 'CORNER' to purchase properties, the seven-letter word 'CONTROL' to gain an advantage over other players, the five-letter word 'TRUST' to form alliances, and the six-letter word 'CARTEL' to form a monopoly. The fifteen-letter phrase 'lockonthemarket' is used to describe the ability to CONTROL prices and limit competition.
