I'm confused here? Why is this a scam? The house always wins and even major betting firms admit that upwards of 90% of their clients will end up losing money.
I don't think there's a house edge. It's either 1- 500 (Lo) and 501 - 1000 (Hi).
I see. I would have thought CP would have put some weighting on it so they can make some money. Why else run a game like this?
