This game i learnt from friends on gaming forums... there are other variations of this game and if there are on this forum then i do apologize. anyway the game goes like this:
There is a hill and you have to do everything and anything to capture it... once you have captured it you simply say "My Hill" Starting....NOW!
I force you to leave the hill and then, I create an invisible, invincible, unbreakable, impassable and inteleportable-through barrier arround the hill!
