If you are about to lose, and you close out the game, it won't register the loss and you can play again from the same point (start the hand over, but different cards). If you do this, it will become blatantly obvious that the game cheats in it's own favor. I just did the same hand 10x. The same person won EVERY time. The same person skipped me 2-3x EVERY time. The win occurred when I was 1 card away EVERY time. The winner is predetermined, and the computer just generates what it needs.
