Don't they? Let's say I rig the slot machines so that they can win on command, and then I hire a couple of actors to come in once every two or three days to 'win' a jackpot. The odds of anyone else actually hitting a win is actually 0 - nada, nothing, zilch. But I can't leave it at zero, if people don't think they have at least a chance, they're not going to throw money at it. With cheating, I have all the benefits of convincing people into thinking they can win, without actually loosing any money in reality. Probably a multitude of other sneaky things you can do with an unregulated casino if someone were to put their mind to it.
