Four games based on 24 have been created so far.
24: Countdown
To promote Season 4 of 24, LG Electronics sponsored a 24-based web driving game for Fox's official 24 website in December of 2004.
24: Countdown takes place between seasons 2 and 3 and involves Jack driving across three stages, trying to stop a terrorist cell from detonating a bomb in Las Vegas.
24: The Game
24: The Game is a Playstation 2 console game from Cambridge Studios, detailing the major events between seasons 2 and 3.
Mobile Phone
i-play has begun to develop 24 games for the mobile phone. In the first game an encrypted message sent to the North Korean consulate is intercepted by CTU agent Chloe O'Brian that implicates the North Koreans in a possible attack on the U.S.A. The North Korean government refutes their involvement in any such operation and adds that any action taken against their people or their consulate regarding these outlandish accusations will be seen as an act of war. You will guide Jack Bauer and other CTU agents through a series of mini-games and puzzles.
DVD Board Game
The 24 DVD Board Game has players taking on the roles of CTU agents, sorting out real clues from red herrings and racing against each other to become top agent.
