erm send them giant spiders, made of gold, with like 15 lions faces. And the lions are drinking big bottles of coke, except if you look close, its actually molten silver and not coke, and the bottles are really gasoline tubs. Then if you play some more you get sent minature little people in the post, and if you're nice to them they clean the lions teeth and clean up the spiders webs.
Then if you win a jakpot or something, they send you a minature house to put the people in, and they have a min jukebox in the house that plays all your favourite music, and once the little people have cleaned up the spider-lion monster thing they have parties in the house and invite loads of fit women over. But because the fit women are proper size they cant get in the mini house, so they will come round and have sex with you if you like, or do some cleaning or just talk and easy you with your problems.
And maybe they could send cheescake over as well if you win a jackpot, thinking about it thats sensible, the little people and the spider-lion monsters need to eat, and everyone likes cheesecake - well unless they're people who think it's real cheese on the cake and not the delicious desert topping.
can't think of anything else at the moment, but im sure I've covered the best stuff.
