What criteria are used to evaluate online casinos?

Casino bonuses are offers that give you something extra to play with, such as free spins, bonus funds or cashback. You’ll often find them as part of a casino welcome offer, but they’re not just for new players. Existing customers can also claim promotions such as reload bonuses and loyalty rewards. Unlike casino welcome bonus offers, reloads can come around more than once. Some casinos run these online casino bonuses every Friday or over the weekend. They’re usually smaller than casino welcome bonuses, but I’d still check the promotions page before depositing.

UK online casinos cater to fans of classic games and those seeking new, exciting UK casino online games options. Betfred Casino is our current #1 because it gives most UK players the strongest balance of trust checks, game choice, payments and offer clarity. The best advice you’ll ever hear from a casino expert is to never claim anything before you read the independent casinos fine print.

Perhaps you’re wondering how you can ensure the casino isn’t lying about its licensing. The good news is that you can prove a licence is valid yourself to make sure everything is legitimate. You need to click the UKGC logo in the website footer or the casino’s licence number (depending on the site). You will then be directed to the operator’s licence, which will indicate whether it is still active.
