The district court judge agreed, ruling in favor of the Trivial Pursuit inventors.

Players move their pieces around a board, the squares they land on determining the subject of a question they are asked from a card (from six categories including history and science and nature).

Each correct answer earns a plastic wedge which is slotted into the answerers playing piece.

Some question sets have been designed for younger players, and others for a specific time period or as promotional tie-ins (such as Star Wars, Saturday Night Live, and The Lord of the Rings movies).

Northern Plastics of Elroy, Wisconsin produced 30,000,000 games between 1983 and 1985.

In December 1993, Trivial Pursuit was named to the Games Hall of Fame by Games magazine.

Questions are split into six categories, with each one having its own color to readily identify itself; in the classic version of Trivial Pursuit, the Geography category is blue, Entertainment is pink, History is yellow, Arts Literature is originally brown, later purple, Science Nature is green, and Sports Leisure is orange.

A small plastic wedge, sometimes called cheese (like cheese triangles ), 6 can be placed into each of these sections to mark each players progress.

This track is divided into spaces of different colors, and the center of the board is a hexagonal hub space.

When a players counter lands on a square, the player answers a question according to its color, which corresponds to one of the six categories.

If the player answers the question correctly, their turn continues; a correct answer on a category headquarters space awards a wedge of that color if the player does not yet have one.

The hub is a wild space; a player landing here may answer a question in any chosen category.

Any number of playing pieces may occupy the same space at the same time.

A variant rule ends a players turn on collecting a wedge, preventing a single knowledgeable player from running the board.

If this question is answered correctly, that player wins the game.

Otherwise, the player must leave the center of the board and try again on the next turn.

The original version is known as the Genus edition (or Genus I ).

Several different general knowledge editions (such as Genus II ) have followed.

Other editions include Junior Edition (1985), All-Star Sports, Baby Boomers, 1980s, All About the 80s, 1990s and others.

In total, over 100 different editions in different languages have been printed.

Worth, author of The Trivia Encyclopedia, Super Trivia, and Super Trivia II, filed a 300 million lawsuit against the distributors of Trivial Pursuit.

He claimed that more than a quarter of the questions in the games Genus Edition had been taken from his books, even to the point of reproducing typographical errors and deliberately placed misinformation.

One of the questions in Trivial Pursuit was What was Columbo s first name with the answer Philip.

That information had been fabricated to catch anyone who might try to violate his copyright.
