Are casinos under legal obligation to run their games fairly and randomly?

Are there any such laws? e.g. poker machines easily draw cards that make the player lose, a dealer deals the cards in favour of the casino, ONLINE casino sites as well are huge - roulettes for example roll 15 blacks if the casino needs it. Are these legal? If not, what claims can you bring against them?... show more Are there any such laws?

Are these legal?

If not, what claims can you bring against them? Can you prove the casino was unfair if let's say they won hands or bets which were only probable less than 1% and this happens like a few times until the player eventually losses?

Thanks!
