Beginning in 1969, three couples competed in the first round in which the first couple to buzz-in with a correct answer scored five points. A wrong answer, however, gave the other couples a chance to score ten points. Only during that first round would all contestants be allowed to buzz-in on all questions. The points were doubled during the last two minutes of the round. The two highest-scoring couples advanced to the next round, played exactly the same as the previous two-couple format. Five-time champions were offered an airplane in lieu of attempting to win two more games.
