Sae-byeok explores an air vent and witnesses workers melting pots of sugar. Sang-woo learns of her discovery and guesses that the next game must be dalgona (honeycomb cookie). Players must extract the shape (circle, triangle, star, or umbrella) undamaged from the honeycomb within 10 minutes.
Sang-woo does not warn his teammates and chooses the simplest shape for himself. He also encourages them to choose different shapes. When Gi-hun chooses the most complicated shape (umbrella), Sang-woo starts to warn him but then changes his mind. Strategically, Sang-woo’s omission makes sense: he maximizes his chances of winning while removing competitors.
