Running Man Vietnam episode 12 features secret hunters and Trấn Thành's setback

In episode 12 of Running Man Vietnam, contestants participated in a high-stakes challenge requiring them to collect number cards to unlock escape routes. The game featured a twist where secret hunters attempted to complete missions and escape while remaining undetected by the rest of the cast.

Ninh Dương Lan Ngọc and Anh Tú Atus acted as the secret hunters, successfully using deception to mislead other players. Meanwhile, host Trấn Thành faced a setback due to overconfidence. After being the first to collect enough cards to win, he chose to stay and socialize rather than immediately heading for the exit. This delay proved costly, as the exit door he intended to use was occupied by another player, Trần Ngọc Vàng, leaving him unable to secure his victory.
