Formerly the Official Monopoly Rules
This page used to hold the “official” Monopoly® rules as stated by Parker Brothers.Unfortunately, Hasbro has decided that fan sites can’t have such things any more, so they have been removed.
You might want to visit these two pages for additional information and clarification:
Monopoly® Rules Explanations explains a few rules that aren’t made all that clear in the official rules.
This page clarifies some of the commonly-missed or misunderstood regular Monopoly® rules, according to tournament play.
I am actively trying to find content to replace the valuable information that was on this page.
