ARG

/ˌeɪ ɑːr ˈdʒiː/

Alternate Reality Game. An interactive story that blurs fiction and real life, asking players to solve puzzles across websites, videos, and social media.

The term is used both precisely (an actual designed ARG) and loosely (any mystery-style internet rabbit hole that feels like one).
