Most all top online casinos voluntarily subject themselves to regular audits (usually monthly) by a qualified and reputable third party firm, such as Pricewaterhouse Coopers (PwC).
These audits generally focus on two aspects of the online casino's operations: their random number generator and their payout rates.

Top Online Casino Payout Rates
An online casino's payout rates are displayed as a percentage — that being the percentage of incoming wagers that are paid out in winnings.
As you can imagine, the higher the payout rates, the better. The top online casinos are often considered so, in part, precisely because they offer the highest payout rates.
A top online casino with the highest payout rate in video poker may not have the best payout rate for slots. Payout rates vary within top online casinos for each individual game.
If you're planning on joining a top online casino for a specific game — be it poker, craps, baccarat, video poker, roulette, blackjack, slots, keno, or any other top online casino game — check the top online casino's payout percentages for that specific game.
