And fortunately, BitZino is "provably fair" by providing a hash of every deck before each play so that it can later be determined that the numbers were not "adjusted".

That is a feature you don't get in Vegas (yet), and not a feature provided even with all bitcoin-related online gambling. But with bitZino (and other "provably fair" gaming services), with every hand is the hash which will match the secret given after each play to ensure the sequence of cards in the deck was random (based on the seed provided by your browser) and did not change during play.
