According to a mathematical study, by Neil Thomson, the best properties to buy in the London version of Monopoly are the orange ones – Vine Street, Marlborough Street and Bow Street. He used probability matrices to come up with this.

(He also said that the key is to buy every street you land on, and to put hotels on one set before you put houses on another. He added that the stations are rubbish, but the utilities are even worse. – Now I know where I’ve been going wrong all these years.)
