In this offbeat game show, players picked up in the Cash Cab have to answer trivia questions with mounting cash values before they reach their destination in order to win up to $1,000. If a player answers incorrectly, he is kicked out of the cab without any money. There are two help options: Mobile Shout-Out (phone call) and Street Shout-Out (asking a stranger on the street). Once the player reaches his destination, he can leave the cab with his winnings, if any, or risk them on a more difficult question. A correct answer doubles his winnings; an incorrect answer means he leaves the cab with no money at all.
