In the first three rounds, play was as in the radio NPB rounds. However, on TV, there was a lockout system: if a team buzzed in before the question was finished that team could not buzz in for approximately 1.5 seconds. The questions increased in difficulty with each round. Each round had 3 categories, and each category had about 4 or 5 questions, but some had 3 or 6. The categories were often given humorous names which had some connection to the content of that category.
