Is it illegal to play guaranteed to win strategies in online casino?

Doubling your bet at the roulette table will not work because you will very soon run into the table limit. I've seen it happen myself in Las Vegas and other places. I once witnessed black come up 24 times in a row for a guy that was using the same method. He lost ALL the cash he had already made prior because he ran right into the table limit before he could hit a win. The casino can be beat in the short run only. Never in the long run. The advantage is always on the house. The edge will grind you out. No way around it.
