Thats why an established name is so important online I think. Small bets is ok many places, I think people build up their use of a casino before really using it fully. There is some oversight and review ongoing, its not quite the wild west when we are this many years in.
I think with magnets in the roulette, the ball that falls on the number is rigged. Magnets pull the ball to the number that is probably rigged with some kind of computer system.
They definitely do spot checks on casinos for this reason. That would be a really shady establishment to be pulling that off, I'm not sure even the Mafia when in Las Vegas did such things ? Weighting of various instruments in a casino is checked quite religiously I believe, gradient and all sorts. Some magnets being added is quite a big deal. I'm fairly certain most places just rely on the house advantage and the costs of drinks etc - the answer to this question will come from Maths
