I've played roulette many times, and yes I agree that doing it with skill on a fair wheel would be impossible. I thought we were talking about potentially rigged games, and just as I couldn't roll fair dice to the same number 20x in a row I'm aware that dodgy dice can be made, so why couldn't a dodgy wheel (or accidentally dodgy by being so old that a noticeable pattern emerges) be made?
