Each mouse caught is worth a specific number of points. Trap components have a minimum points requirement, should a hunter fail to meet the requirement they will not be able to purchase the component. Points determine your rank on the scoreboard.
Points are gained by catching mice. The heavier the mouse is, the less points it is worth. Since a smaller mouse is faster, it is more challenging to catch, and therefore worth more points. In certain areas, the mice might steal points if you attract but fail to catch them, including the Harbour, the Mountain, the Calm Clearing, the Great Gnarled Tree, the Lagoon, the Laboratory, the Town Of Digby, the Mousoleum, the Bazaar, the Training Grounds, the Dojo, the Meditation Room , the Pinnacle Chamber, the Catacombs, the Forbidden Grove, the Acolyte Realm, the S.S. Huntington II, the Cape Clawed, the Elub Shore, the Nerg Plains, the Derr Dunes, the Jungle Of Dread and the Dracano. Losing points does not affect rank progress and thus will not cause a Hunter to drop in rank.
25 points are also awarded each time you sound the Hunter's Horn. You gain 10 extra points for each hunter in your hunting group at your location and yet to sound the horn, up to a maximum of 250 points.
