There is no way of knowing for certain if online blackjack is fixed. However, it would be close to impossible to get caught if the online casinos programmed themselves an extra 3-4% edge. If you think all online casinos are on the "up and up" you are extremely naive.
I'd steer clear from them at all costs.
Online blackjack doesn't need to be rigged, the rules of
the game gives the house a built in edge that
is enough for the online casino to make a killing.
How the hell do you think the casinos keep the lights on
24/7 in vegas?
I think it clearly is rigged and I also agree with GTC08 that the selections you chose to speed up the game (repeat same bet and fast deal) make it that much more a losing proposition.
"The games aren't rigged. They don't need to be."
The comment makes no sense. It is like saying why do loan sharks take 25% when they can do quite nicely getting 15%.
The answer is why get a 3 or 4% edge when you can get a 7 or 8% edge? The fact that they can get away with it is reason enough as there is no regulation.
