Their standout feature is their wonderful live interactive games, featuring plenty of favourites including Monopoly and Crazy Time.

What makes Coral special is their jackpot collection – with over 130 progressive titles.

The blue-themed platform is organised into clear sections, making navigation straightforward even for casino newcomers. Their payment processing is solid, with PayPal withdrawals completed within eight hours. While their 92.35% payout rate sits slightly below some competitors’, their regular promotions more than make up for it.

6. Fitzdares

Fitzdares offers new players a 100% match casino bonus up to £100 when you deposit at least £10 and stake £20 on any slots within 48 hours. Their carefully curated game selection complements their renowned sports betting platform with premium slots and table games.

What caught our eye right away was the sheer number of bonuses and promos available. These deals roll across the screen on a slow conveyor belt above the games library. The welcome bonus was generous enough to get us in the door but it’s nice to know there are other ways of boosting the bankroll later down the line.

A great slot casino has a mix of classic and new releases, decent RTPs above 96%, and regular free spin promotions. We’ve listed our top picks below to help you find the perfect slot site – including wager-free bonuses.

Blackjack

The best blackjack casinos offer multiple variants with favourable rules like 3:2 payouts; dealer stands on soft 17, and the ability to double after splitting. We’ve added our top blackjack casinos below, chosen for their game variety, low house edges, and smooth gameplay across both digital and live dealer options.

Roulette

Roulette combines simplicity with excitement, making it a casino classic. The best roulette sites offer European and French variants (with lower house edges) alongside American and special versions. We’ve selected our top roulette casinos below based on game variety, wheel fairness, and special features like multi-wheel play.

Poker

The best poker sites offer a mix of video poker machines, live dealer tables, and dedicated poker rooms for tournaments and cash games.

Live Games

Live casino games bring real dealers and genuine interaction to your screen. Top live casinos offer HD streams, professional dealers, and games from Evolution, Playtech and Pragmatic Play.

We’ve picked our top 5 live casinos below based on game variety, stream quality and betting limits that work for all players.

Payouts

High-payout casinos give players better value. A good payout rate (RTP) shows how much money wagered is returned to players – the higher, the better. Online casinos typically offer RTPs of 95–98%, much higher than land-based venues. Below, we’ve listed our top payout casinos, all offering above-average returns across their games and are regularly tested by independent regulators such as eCOGRA and iTech Labs.

Fast Withdrawals

Fast withdrawal casinos are crucial for players who value quick access to their funds. Nobody wants to wait days or weeks to get their money. The best fast withdrawal casinos process payments within hours rather than days, with some offering instant payouts through e-wallets and cards with Fast Funds technology. Quick withdrawals indicate a casino’s financial stability and commitment to customer satisfaction. Below, we’ve added our fastest withdrawal casinos, all offering speedy access to your winnings without unnecessary delays.

Welcome Bonus

Duelz Casino offers an impressive welcome package with a “100% Matched Bonus up to £100 + 100 Free Spins” on Book of Dead. The free spins are given in batches of 20 over five days – you’ll receive the first batch when you make your deposit and the rest over the next four days. The minimum deposit is £20, with a maximum bet of £2 while the bonus is active.

Free Spins

Bally Casino has a great free spin offer with its “Spend £10, Get 30 Free Spins” that comes with zero wagering requirements – what you win is yours to keep without any playthrough conditions. These spins can be used on the Secret of Phoenix Megaways game. Bally also provides ongoing rewards to existing customers including free spins, cashback, and cash prizes on a weekly basis.

Cash Back

If you’re looking for a good cashback casino, then All British Casino stands out as our top choice. They offer a genuine 10% cashback on all your losses with no wagering requirements – what you get back is real money you can withdraw immediately. This cashback is calculated from your first deposit onwards and can be claimed whenever your account balance falls below £10.

Debit or Pre-Paid Cards

Debit cards remain the most widely accepted payment method at UK casino sites. Visa and Mastercard debit cards offer instant deposits, widespread acceptance, and the ability to claim welcome bonuses that might be restricted with other methods. Pre-paid cards like PaysafeCard give you extra control over your spending and add a layer of privacy since you don’t need to share your bank details. They’re ideal if you want to stick to a strict budget or prefer not to link your bank account directly to gambling sites.

E-wallets

E-wallets have become increasingly popular for casino transactions due to their speed and convenience. PayPal stands out as the most trusted option, available at over 50 UK casinos, offering instant deposits and typically faster withdrawals than cards. Its strict security measures and buyer protection make it a great choice for safety-conscious players. Skrill and Neteller provide similar benefits with even wider acceptance but come with a significant drawback – many casinos exclude these methods from welcome bonuses and promotions.

Pay by Phone

Pay by Phone lets you make casino deposits and bet by phone bill, offering simplicity and instant transactions. This method works with major UK networks including Vodafone, Three, O2 and EE. The main advantages are convenience (no need to enter card details) and additional security since you’re not sharing financial information. However, there are limitations – you can’t withdraw using this method, deposit amounts are typically capped at £30 per day, and some operators charge processing fees (up to 15% in some cases).
