"Categories is a word game in which players think of words that begin with specified letters and belong to specified semantic categories. For instance, given the letters in "Sargon" and the category "U.S. states", one can list:

* South Carolina
* Arkansas
* Rhode Island
* Georgia
* Oregon
* North Dakota

A typical game consists of choosing five initial letters and five categories. These become the rows and columns of a 5×5 grid which the players attempt to fill within five minutes. If there are only two players, the one who fills more of the 25 combinations is the winner. If there are more than two players, the scoring usually discounts any entries written by more than one player."
