First up to compete against each other were the group's oldest members, Insung and Youngbin. The latter had a winning streak playing a Korean version of rock-paper-scissors for the first few rounds. The boys then tortured�Insung, who had to face punishments like raising his voice a key for the rest of the game, being sandwiched under all of the members, and rolling on the floor while screaming. Insung soon got the hang of the game, however, which resulted in Youngbin being punished in the form of calling the CEO of 'NewsAde' and getting her to say "I Love You"!

The boys serenaded her on the spot�and earned the response in no time. Next up were Dawon and Taeyang playing the zero game, resulting in some rough punishments, one involving kissing... (Two SF9 members were not able to attend the game due to personal schedules.)

Watch SF9 being fun above, and be on the lookout for part 2!
