How are game outcomes determined?
The outcome of online casino games are determined by various random number generation systems embedded in the casino software.

In order to demonstrate game fairness, casinos/software developers now have their historical return to player rates audited and verified across all games by the accounting firm PriceWaterhouseCoopers. Rates are typically verified in the range 96% to 99%, proving returns are just as good, if not better than those offered at traditional casinos.

I have also read player claims that at certain casinos outcomes appear random until the ante is upped, then all of a sudden the dealer wins all the high value bets.

However, if we leave aside the less than scrupulous operators and address the legitimate casinos, then the answer to this question is that outcomes of the games are determined by various random number generation systems. Casinos using Boss Media software, for example, employ a Geiger-Mller Tube Detector to guarantee random number generation. Therefore, the number that the roulette ball lands on, the number that the die add to in craps, or
