The nail-biting 'mafia game' came to a shocking conclusion on the latest episode of 'Running Man'!

With four mafia members hidden within the cast and guests, the innocent citizens would have to eliminate all of them through voting rounds. If a single mafia member remained at the end, the mafia would be the final victor.

At the end of each game, the game's winners would be excused from the list of suspects, leaving the rest of the cast and guests to determine two mafia suspects from the group and eliminate them.

By the final game, the cast had succeeded in eliminating all but one of the mafia - Oh Man Suk, Kim Min Jong, and Kim Jung Nan. However, the verdict was torn on who could be the final suspect.

The final mafia member turned out to be none other than Ji Suk Jin, who managed to hide his identity throughout the entire day by playing it cool and keeping a low profile! Since none of the cast expected this shocking twist, he ended up surviving the round-up and grasped the joys of victory.
