The cast members of SBS's variety program 'Running Man' put on a fierce battle to see who could win the true title of the 'ddakji king'.

The game began with a heart-pounding hide-and-seek in the early morning, made even more exciting by the presence of professional mixed martial arts fighter Choo Sung Hoon and actress/professional boxer Lee Si Young.

Along the way, the teams would have opportunities to pick up cash through a series of games, competitions, and challenges, which they could then spend on a variety of ddakji - folded-up pieces of paper - to use in the final battle, where each team would vie to flip over as many of the other teams' game pieces as possible.

Although the original 'ddakji king', Yoo Jae Suk, put up a formidable challenge, the eventual win went to Kim Jong Kook, who then celebrated his hard-won victory and the new crown of the 'ddakji king'.
