I will again mention Bayes theorem (to the newcomers to this post). Assuming your a priori guess as to the probability of being cheated is only 1/1000. You would only arrive at an 0 for 50 1/29000 honestly. Your post event guess as the chance that the game was honest is (1/29000)/(1/1000)=1/29. Even if your a priori guess was your chance of being cheated was only 1/10000 you still conclude that your post priori chance that you were cheated was about 2/3. Also it would not surprise me: Never overestimate the intelligence of a casino.
