Say you play video poker in Vegas. Are the cards not dealt completely randomly? Do the previous cards dealt affect the cards dealt in the next round? Is the game not completely analogous to if somebody dealt you the cards in real life from a well shuffled deck? To my best knowledge that is how video poker machines should work according to the law. And there isn't any need for them to work in any other way because the pay tables make sure that the casino will win on the long run.
