A casino earns a high score for its promos if new players can sign up with both a £50+ deposit match and large number of free spins, especially if these include no deposit offers. After that, we check if there’s daily and weekly bonuses up for grabs, and a VIP or loyalty scheme offering regular players the chance to claim extra rewards.

We are constantly checking UK regulations and will update our website accordingly when there’s a change in the law. The first thing you’ll bump into is a plethora of online casino bonuses to choose from. The welcome bonus is the biggest attraction at UK casino sites, and it is easy to see why. Players can benefit from generous offers simply by signing up and making their deposit. Our experts look at deposit matches, free spins, wagering requirements, maximum bets, expiry periods and any restrictions on winnings. We also pay attention to wager-free promotions and other simpler bonus formats that have become increasingly popular. That’s why every casino featured on Casivo goes through the same review process. Our team signs up, explores the platform and, where appropriate, deposits and tests key parts of the player experience.

We only recommend legitimate and fully licensed online casinos, regulated by the UK Gambling Commission and other licensing regulators in British territories.
