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 use a Black Hole Generator to destroy your hill, then I make it into a wormhole, travel to a parallel universe, claim a hill, and build a black hole reactor which is programmed to blow up if anything gets inside the then empty universe apart from me, thus obliterating it, the hill, and all dimensions except for me, who can escape in my trusty TARDIS.
