round decided on who would play for the Million Peso Jackpot Round, with the defending winner choosing a question from a category to ask the challenger. If the challenger gave all the correct answers, they were declared the winner and kept the prize; answering incorrectly meant the challenger lost and they left with half of the ₱50,000 prize, and the defending winner advanced to the next round. The winner of the clincher round advanced to the Million Peso Jackpot Round, where they answered a question from a category they chose (e.g. Arts & Literature, Geography & Nature, etc.).

If they gave an incorrect answer, they had to return in the succeeding episodes and increase their winnings.
