Before each phase of the escape challenge, the members first gather in the bus. Since the second challenge (third episode) of Season 1, the program team will assign the captain (주장) of the period in response to the performance of the members of the previous challenge, and the captain will receive an armband. Prior to arriving the location, members will wear eye masks, and the staff will lead the members to the start point in the large secret room. After fulfilling the instructions of the staff, the members can remove the eye mask. In each challenge, members need to use the clues in the room to gradually explore the large secret room until all members escape from the location. Each challenge has a different theme, and members will learn about the context of the background story from the clues during the exploration. In addition to finding and cracking the clues, members may need to interact with the story characters played by the staff (such as helping the character, leading the character to escape, etc.) before they can escape from the large secret room. There is no stipulated time limit for each escape challenge, it will only end when all members and story characters (if any) have successfully escaped.
