Nam Woo Hyun, Kim Ha Neul, and Lee Jun Young join the cast for this week's Roulette Battle of Weak Loyalty Race, where unexpected alliances take center stage. A large roulette wheel with 60 empty slots will slowly fill through missions and games with their names. They will spin the roulette wheel at the end to determine which three members will get the prize or the penalty. However, if it lands on an empty slot, all members suffer the penalty. Who will walk away with the reward, and who will fall victim to the roulette of fate? (thetvdb.com)
