The two contestants, in turn, were read a (usually) four-part question in their category. The current champion, or the winner of a coin toss, decided whether to play first or second; while the first player heard the question and answered it, the second would be placed in an isolation booth. After the first contestant had answered, the isolated player was given the same question. Whoever answered more parts of the question correctly won (see below for the money scale), and had the option to either quit with the amount of money they'd just won, or face another opponent on the next episode with the risk of losing all the money if they failed. In the event of a tie, both contestants won money and each got the option to stop or continue. In order to actually win the money, however, the winner needed to answer at least two questions correctly, regardless of category.
