In Masters of Commerce you take on the role of a freewheeling capitalist out to outmanoeuvre your competitors and earn your place as a great industrialist. Players are divided into landlords and merchants. Your goal is to earn more money than any other landlord (if you are a landlord) or more money than any other merchant (if you are a merchant) by the end of the fifth round. Each round landlords and merchants negotiate with each other in a two minute free-for-all to set rent agreements on the landlords' properties. Merchants then collect income from the properties they rented but not until a roll of the dice has brought changes to the value of the four colours of properties. Landlords collect rent from merchants, pay taxes on their properties, and buy new properties at auction. At the end of the fifth round the merchant with the most money and the landlord with the most money are each declared winners, the true Masters of Commerce.
