Rules of Acquisition Explained: The Ferengi Business Code

Short answer: the Rules of Acquisition are a list of 285 business sayings that Ferengi characters in Star Trek quote all the time. They are about making profit, and they are often funny. Here is what some of the best-known ones mean in plain words.

What are the Rules?

In the Star Trek world, the Rules are old guidelines for doing business the Ferengi way. We are told there are 285 of them, though only some have ever been heard on screen. They were first mentioned in the Deep Space Nine episode “The Nagus” in season 1. The Ferengi say the Rules were written long ago by a leader named Gint. In one story, Gint even admits they were more of a clever marketing idea than real law.

Well-known rules, in plain words

  • Rule 1: once you have someone’s money, you do not give it back.
  • Rule 3: never pay more for something than you have to.
  • Rule 6: never let family get in the way of a good deal.
  • Rule 7: keep your ears open.
  • Rule 9: a good chance plus good instinct equals profit.
  • Rule 10: greed never ends.
  • Rule 34: war is good for business.
  • Rule 35: peace is good for business.
  • Rule 59: free advice is hardly ever cheap.
  • Rule 62: the riskier the road, the bigger the profit.
  • Rule 285: no good deed goes unpunished.

These are our own simple summaries, not word-for-word quotes. The exact wording changes a little between episodes and books.

Why are they funny?

The rules are said in a very serious voice, but many of them show how silly it is to put money above everything. Rules 34 and 35 seem to say opposite things, yet both are “true” for a trader, because a good Ferengi can find profit in any situation.

A fun fact: rule 286

When Quark once makes up a rule number 286 about one of his regular customers, his brother Rom points out that there are only 285 rules. Quark simply says there should be more.

Do the Ferengi follow them?

Mostly, but not always. Quark likes to quote a rule to win an argument. Yet in many episodes he breaks the rules for a friend, and that is where the story gets interesting. In one episode, the rules are even rewritten into opposites, such as “if they want their money back, give it to them”.

Where to hear them

You will hear the rules most in Deep Space Nine, but they also appear in other Star Trek shows, novels and books.
