The following are the various Ferengi Rules of Acquisition we have heard over the run of Star Trek. There are 285 rules (DS9, "Rules of Acquisition"), and they were written by Gint, the first Grand Nagus, and his cronies (DS9, "Body Parts").

The list is based on the Encyclopedia, and so may omit some mentioned in later DS9 episodes. As usual, any corrections or updates should include the number and text of the rule, the episode it's from, and if possible an idea of where in the episode it is mentioned.

In the episode "Prophet Motive", the Grand Nagus produced a revised set of the Rules of Acquisition whilst under the influence of the Bajoran Prophets. The following are the known rules from this set, all copies of which were destroyed when the Nagus regained his original personality.

1 If they want their money back, give it to them. DS9 "Prophet Motive"
10 Greed is dead. DS9 "Prophet Motive"
21 Never place profit above friendship. DS9 "Prophet Motive"
22 Latinum tarnishes, but family is forever. DS9 "Prophet Motive"
23 Money can never replace dignity. DS9 "Prophet Motive"
285 A good dead is its own reward. DS9 "Prophet Motive"

Additionally, the Voyager episode "False Profits" featured Neelix telling two Ferengi stranded in the Delta Quadrant that rule of acquisition number 299 was "When you exploit someone, it never hurts to thank them". We do not know if this is an accurate quotation; if it is, then we would need to believe that the Ferengi have added extra rules sometime prior to Voyagers accident and that Neelix has read up on these since.

In DS9's "House of Quark", Quark himself suggested an additional rule : Rule 286, "When Morn leaves, it's all over". Quark was bemoaning the state of his business at the time, and it is unlikely that this rule is a real one.
