For us, that means judging new technology by whether it genuinely improves the player experience, rather than simply being a new feature. Casino platforms are becoming better at organising content around individual preferences, making it easier to discover relevant games and promotions. This means that being a casino player is ever-changing, and you are one of the first to benefit from these new creations. There’s also no sign of this slowing down, with this year proving to be one of the biggest yet. Slots n’Play have an exciting offer up for grabs for any new players that sign up. When reviewing casinos, we test the process first-hand by signing up, submitting the required documents, and assessing the ease and speed of the process. Most British gambling sites verify the documents in 24–48 hours, but they can take longer during busy periods or in case of errors. Unless you plan on completing the KYC process long before you have to make a withdrawal, consider how long the casino takes to approve the verification documents.
