A casino’s payout rate refers to the percentage of total bets returned to players as winnings. This is closely related to Return to Player (RTP), which applies to individual games. For example, a slot with 96% RTP theoretically returns £96 for every £100 wagered over time. Similarly, a casino with a 96% payout rate will, on average, return £96 of every £100 bet at the online casino.

User experience is one of the key factors in online gambling, just like it is in any online business. If your users don’t like using your site, it doesn’t matter at all what you have in there. The United Kingdom Gambling Commission keeps tabs on the casinos it has licensed and makes sure that they follow the rules and regulations. If there are any discrepancies, the casinos will be severely fined or have their licenses revoked.
