This game is pretty much just to have fun & hang out with fellow KoA'ers, the xp isn't phenominal but the game is ridiculously easy.

Gnome Ball is a members-only minigame.
This is technically a dangerous activity, (if your level 10 maybe) but if you die I will be there to bless you & make fun of you for the rest of your RS life for getting killed by a gnome

In Gnome Ball, one or more players aim to score goals against gnomes. This is done by throwing the gnomeball into the goal. Cheerleaders near the field will root the player on, announcing each goal and winning of the game. Ranged experience is gained each time the ball is thrown, and Ranged and Agility experience when a goal is scored. When players enter the field, they can talk to the referee & learn how to play.
