Trivial Pursuit: Unhinged is a video game developed by Artech Studios and published by Atari Interactive based on the trivia board game of the same name.
Players take turns moving their pieces around the Trivial Pursuit board answering questions in six different categories to win one differently colored "pie piece" in each category.
The first player to collect all six "pie pieces" and answer a randomly selected question in the game board's hub is the winner.
The titular Unhinged mode is a variation of Classic mode where players can bet on their opponents' game performance and certain spaces on the game board are given different properties including: This is a quick two-player mode in which each player starts at the bottom of a tower and chooses a question in one of two random categories, each correct answer brings the player up a tier on the tower.
Atari announced the game on August 15, 2003 for a release during the Christmas season.
