Wikipedia:Articles for deletion/Treasure hunt (game)
The fact that there's a https://www.guinnessworldrecords.com/world-records/largest-treasure-hunt-game specific world record for this indicates that it's a separate topic with a distinct title.   There are numerous books about the activity by this title and so it's quite notable and sourcing the topic will not be difficult.  Other similar activities such as egg hunts or geocaching have separate and distinct features and, per , there's no need or benefit from trying to cram everything together
