The founder of Playtech, Teddy Sagi, was in prison for stock market fraud. I do not think the live Blackjack on Playtech is transparent. The shoe is taken away from the table for a few minutes to be shuffled elsewhere, rather than in full view of the player. It would be relatively easy to "adjust" the shoe so that even if it is shuffled once at the new table, there will be a larger advantage for the house. One simple method is to group tens together, called "touching tens" in the casino cheating industry. The only fair game is one shuffled in full view of the player.
