During the first season, after the TV went "Off the Air", gameplay continued as normal with the remaining two contestants until time expired. Beginning with the second season, this format was scrapped for a "lightning round" to determine the winner.
Think Real Fast[]
In Seasons 2-4, the two remaining contestants competed in a 30 second speed round entitled "Think Real Fast". Typically, this was a fill-in-the-blank or spot-the-errant-word format. For example, Ober would read movie, TV show, or song titles that had one word replaced with a different word, and contestants had to come up with the correction. The high scorer moved on to the bonus round, while the runner-up was eliminated in a manner similar to the third place contestant.
This, That or the Other Thing[]
In the fifth season, as well as the second season of the syndicated version, all three players played a different version of the lightning round called "This, That or the Other Thing," but it was not the last round in the game. All questions now had one of three answers that Ober would list before the round started. These were usually people or characters who shared a common name, for example: "Andy Taylor, Andy Warhol, or Andy Rooney." Contestants had 20 seconds to ring in and answer as many questions as possible; after this round, the TV immediately went "Off the Air" and the third place contestant was eliminated.
