This week, Kang Han Na is back alongside Lee Hee Jin of Baby V.O.X, Yoo A from OH MY GIRL, and the very comic Yoo Byung Jae. It's an individual race this week where the right investment takes the win. In a series of games, four members will face each other in competition while the rest place their bets on one person winning. Each of the four members selected will have different odds of winning, thus making the rewards higher but riskier. The loser faces the water bomb. (thetvdb.com)
