So what you are saying is that some of these casino does have some sort of back door to adjust the odds in their favor. If it were a truly random game they would not be able to win 13-14 hands in a row all the time, the odds are highly against it, yet it happens all the time. It would be like if you were sitting at a table in a land based casino, all of the sudden the pitboss comes up and removes some aces and 10s from the deck, because 'they had been paying out too much that day'. If they really are capable of doing this(adjusting the odds to offset some payout to another player or bonus) then you are taking a gamble on a gamble, but i guess thats what online gambling is all about, you have no idea what the guy on the other end is up to.
The statement 'if they were rigged then the player could take advantage of it' is totally false. How can you win when its programmed to make you lose?? There is not a definable pattern to it, but the losing streaks drag on for suspicious amount of time. Best thing to do, if you lose 2 hands in a row, reduce to a $1 bet, play about 7-8 hands then bump your bet back up, that strategy seemed to work for me. Increasing your bet on each loss is a stupid way to play, all they would have to do is win 10 hands in a row and you are toast.
