The clock started when the category for the first subject (Place, Thing, etc.) was displayed on the screen and the subject was shown to the giver. Up to six clues would be shown, one every two seconds; when the giver believed there was enough information for the guesser to figure out the subject, he/she said, "Solve it!" and no further clues were shown. The guesser then turned to the screen, offered a guess, and turned away again. The contestant won $10,000 if the guesser correctly identified five subjects before time ran out, or $250 per correct answer otherwise.
