The Best Online Casino Reviews & how we Rank UK Casino Sites

Any of the best online casino sites that intend to stay on top of the rankings must comply with a number of features. Below are a few criteria, from Casino Deal’s point of view, to help you understand the independent reviews we publish.

Variety of Games at Online Casino Websites

  • Casino and games: There must be a wide variety (slot machines, roulette, cards, etc) and gameplay options (live, mobile, progressive prizes, etc).
  • Jackpots: How much are the jackpots? Jackpots are the main attraction for bettors who like to compete for huge sums. After all, who does not want to become a millionaire whilst having fun?
  • Offers: Welcome bonuses and promotions make a difference as well as loyal members. The bonus and offers are the factors that accumulate the most points in reviews.

Do they have a Live Casino or host Live Casino Games

There's been a big uptake within the best online casino sites for a Live Casino offering. This brings you closer to the action as there are real people dealing the cards and spinning the wheels.

With some great Live Casino software providers out there, our reviews make sure they cover in detail this side of things.

Reputable & Trusted Online Casinos – Licencing

All online casinos must have permits for operating, provided by the government agencies for the country where their headquarters are, to act legally. Not just the best online casino sites, but all online betting sites must have an appropriate operating license.

In order to accept UK players, every online casino must be licenced by the UK Gambling Commission The most common licences held by the best online casino sites are from Malta, Curacao, Alderney and Gibraltar.

Find the Best Online Casino Slots and Table Games

We detail the best online casino slots out there today, so regardless of what you like, we have you covered. There are loads of different types of online casino slots to check out, all suiting different types of player.

High Roller Slots

If you’ve landed here, then you’re most likely a VIP who plays big to win big. The only thing you’ve got your eyes set on is the highest RTP (return to player). You most likely get treated with custom VIP casino packages, bonuses and free spins or tournaments. Online casinos reward those who wager high whilst chasing the big one.

High roller slot games have the largest of all wagering possibilities, ranging between £20 to £5000 per spin. In some cases, it’s been known that players have been able to wager £100,000 per spin. High roller slots carry medium to high volatility.

One of the Best VIP Slots is Bonanza

Bonanza by Big Time Gaming is popular among high rollers and VIP because of the high volatility and big winnings. If you are keeping ahead of your game and on the punt to bet big and cash out even bigger, then this is our slot of choice!

Beginner Slots

As a beginner or the average player, gaming is about having fun. Our favourite slots are themed on TV or music bands, which have cool features, graphics, bonuses, wilds, scatters and music. The best tips for online casino’s as a beginner is to play slots that have a lower volatility. Payouts that come more regularly (but with lower amounts), increases the entertainment factor.

One of the Best Slots for Beginners is Rainbow Riches

Rainbow Riches is one of the world’s most popular slots at both online and land-based casinos. Whether your hunting Leprechauns or spinning the reels for some amateur fun, this is a slot where winnings are very common but on a smaller payout to other slots.

Jackpot Slots

Never stop dreaming! Some of the biggest wins have been on jackpot slots. There a few jackpot slots at most online casinos, but the ones to keep your eyes peeled for are the progressive jackpot slots. Progressive jackpot slots are shared amongst multiple casino sites with several common pots (jackpot pools). Millions of £’s are won in a single spin on the major jackpot, with consolation jackpots to be claimed worth hundreds of thousands of pounds.

One of the Best Jackpot Slots is Mega Moolah

By far the slot machine that has turned most slot players into millionaires. This Microgaming jackpot slot holds a Guinness World Record for handing out £13,213,838 to a lucky player from Leeds playing at BetWay.

Mobile Slots – Our Best Mobile Slot is Starburst

Starburst slot is the most popular mobile slot and it hands out free spins like no tomorrow. This slot was developed for mobile phones. Interestingly, the desktop version was released later. A true mobile classic, one of the most popular overall slot games ever made.

The Best Online Casino Bonuses Explained

There are many advantages that online casinos have over land-based casinos. One of these advantages is the amount of casino bonus offers that are available to both gain and retain players. There is a range of different types of online casino deals, varying in size, form, and type.

Matched Deposit Bonus (commonly found as a Welcome Bonus)

The most common bonus that you see in the best online casino providers listed here on Casino Deal is the matched deposit bonus which is regularly packaged as a welcome bonus. This is a bonus, which is often based on the first deposit or deposits.

Example: 100% up to £100 + 10 free spins. In this case, you receive a £100 bonus if you have deposited £100, thus totaling £200 to start playing with. It's key to remember that all bonuses come with key terms and conditions attached. Notably, the wagering requirements, where you must turn over the bonus and/or the deposit a number of times for winnings to be released.

Free Spins No Deposit Bonus (commonly found as a Registration Bonus)

All you need to do is create an account, in order to instantly receive free spins in your account on popular slot games, without depositing any funds. Hence, it’s a no deposit bonus.

Reload Bonus Offers

Online casinos occasionally offer existing players reload bonuses. This is a means of maintaining both satisfaction and engagement. It is also a way to keep existing customers coming back to the site in question in a very competitive space.

Cash Back Bonus Offers

When players wager all their funds, they may occasionally receive Cash Back bonuses into their accounts to recuperate a percentage of their total losses. Obviously, this is a very exciting bonus offer that is increasing in popularity amongst online casinos.

Casino Bonus Codes are Important

Casinos Bonus Codes are something like discount coupons. You enter a code and get a gift. Attention: The bonus codes consistently vary. Interestingly, special offers are negotiated at many online casinos. The bonus codes guarantee that you will get those bonuses. There are cases where the casino provider only knows through the bonus code that you are eligible for the special bonus.

Casino Deal takes Responsible Gambling seriously

Both entertaining and profitable, you can’t always win when gambling. Being ready for a loss is all part of the game. We support Responsible Gambling and encourage you to not risk funds and time that you can’t afford to lose.

Gambling is addictive and it is difficult to recognise addictive behavior in yourself or others. Have fun, be aware and stay in control of your gambling behaviour. Most casinos will help you set gaming limits on yourself through both finance and time limits.

You can read more about this on our Responsible Gambling page, where you'll find information on lots of resources that offer help and advice such as begambleaware.
