This is one of the most frequently asked questions. The conch game can only be done by priests. That is, by people who are invested in this mission as a result of years of study and practical training. Try to think of the priest as the spiritual equivalent of a doctor in the material dimension. Just like, I think, you would not be accepting a medication from someone who does not have a medical degree, or you would not have surgery for someone who is not a surgeon, you would not want to be spiritually advised by someone who is not specifically prepared to do it.
