Hunter is a term that refers to an individual MouseHunt player. Every player who adds the MouseHunt application gains this title. There are several Ranks of hunters, which affect how and where one can hunt.
Every hunter can have several people in their hunting party. Your hunting party grows if you have more Facebook friends online and hunting in your location. With a larger hunting party, your friends can sound the horn for you, sending you on more hunts, so long as you are online within the last hour. Otherwise, only the hourly trap checks can happen without the hunter's input. You must log into MH once per 24 hours to recieve the hourly trap checks.
