How Do We Find The Best Gambling Sites Online?

When picking out the best gambling sites online, it’s natural to look for those offering the top gambling deals. A plethora of gambling operators give new UK customers the chance to pick up brilliant sign up bonuses. 

The best casino welcome offers usually come in the form of matched deposit offers, free spins packages, promo codes, classic free bets, and occasionally a combination of these. There are usually strings attached, however, with even the best online gambling deals having stipulations attached including wagering requirements, which can sometimes take the shine off a good-looking bonus.

This is where a comparison site like GamblingDeals.com can help. We’re passionate about helping you find the top gambling offers from the best UK gambling sites online.

The UK’s Best Online Gambling Sites for 2021

How Do We Compare The Best Gambling Sites?

Here’s a quick breakdown of what we look for when reviewing the UK’s best gambling sites.

The Range of Gambling Products

It’s always important to consider exactly what kinds of betting opportunities are available at an online casino. Can you wager on sporting events as well as casino games, for example? Are bingo rooms part of the mix? We look closely and highlight these finer details and more.

The Diversity of Casino Games

The range of casino games can vary a great deal between casino sites. We make a note of what’s available – if a site specialises mainly in slots games, for example, or if there’s an equally big focus on table games like roulette and blackjack, or live casino experiences. We also check if there are interesting variations on classic casino games, progressive jackpot games, and more.

Casino Software Partnerships

An online casino is only as good as the games on offer. If a site has partnered with the best software developers, you’ll know you can access the casino games available. The presence of industry leaders like NetEnt, Evolution and Microgaming is a sign of a great site, although we like to see a few offerings from the younger companies expanding the possibilities of online gambling.

Licensing

Security is paramount when it comes to online gambling. That’s why we’ll only review sites that are licensed by the UK Gambling Commission, one of the world’s most respected authorities within the gambling industry. It requires gambling sites to be audited for fair play and provide responsible gambling tools for members.

Payment Methods and Withdrawal Options

Depositing and withdrawing funds without too much fuss and bother is an important consideration for most bettors. If a gambling site has a good range of banking options, from debit cards to various e-wallets, that will certainly earn brownie points from our experts.

Available Sportsbook Odds and Gambling Markets

When assessing online bookmakers in the UK, we like to see a wide range of sports covered, from biggies like football and tennis through to more niche passions like volleyball and handball. A good spread of betting markets and odds is also key, so sports fans can bet on all kinds of outcomes within individual events.

Sportsbook Tools and Features

The best online bookmakers will provide tools and extras to enhance the sports betting experience. These include bet builders, bet editors and the ability to cover your accumulator bets with Acca insurance. We also look for in-play bets and early cash out options.

Customer Support and Full T&Cs

It’s not the most exciting part of betting online, but it’s important that any gambling site clearly lays out the full terms of its games, betting markets, promotions, and anything else that’s necessary. Customer support should also be easily contactable – ideally in a range of ways including phone, email, and 24/7 live chat.

Our Top Gambling Sites Checklist

The GamblingDeals.com review process is geared towards helping you find an all-round positive experience when you join a new online gambling site. For a more comprehensive breakdown of how we find the best gambling sites, check out our gambling offers discovery checklist below.

Compare the Best Gambling Sites

At Gambling Deals, we know players like to have as many options as possible when they join a UK gambling site. After all, you may feel like placing sportsbook wagers one day and playing casino slots and table games the next. If you’re a member of a site that offers a good range of gaming options, you can do exactly that in one place. 

That said, we also recognise that some UK customers are after a specific sort of experience. That’s why we’ve made it easy for you to navigate and search through various types of sites, from minimum deposit casinos to no deposit bingo sites and beyond.

Finding the Best Gambling Offers

Pretty much every gambling site will offer you sign up bonuses and ongoing promotions. These can include matched deposit bonuses; free bet offers, and free spins on popular slots. That’s a lot of information to digest, but don’t worry. At GamblingDeals.com, we’ve done the legwork for you. We’ve gathered all the essential information on bonuses and their terms and conditions, and ranked the best online gambling deals in one place to make it a breeze for you to find your next online casino! 

Fast Ways to Join and Play

Once you’re ready to join a new gambling website, just follow our link which will take you straight to the sign-up page. It’s usually a very straightforward process:

1. Enter your personal information and create a new password
2. Verify your age and address as part of the legally mandated KYC (Know Your Customer) process – This may require showing documents such as a passport, driving licence and recent utility bill
3. Visit the casino’s cashier
4. Select your chosen deposit method – Debit card, NETELLER, Paysafecard, Skrill, etc. – Be aware, some methods are not eligible for deposit bonuses
5. Select your deposit amount and add any codes for welcome bonuses 
6. Start playing your favourite casino games!

Securing the Best Gambling Offers

Weighing up the best gambling offers is about more than just comparing how much you’ll receive. You also need to check the full terms so you’re fully aware of any strings that may be attached.

For example, you’ll need to know if there’s a minimum first deposit or bet required to unlock the bonuses. Once you have the bonus credits or free spins, there will usually be a fixed time limit by which they need to be used. Many bonuses will also have wagering requirements attached, meaning you’ll have to bet the bonus amount or free spins winnings a certain number of times before you can withdraw the bonus profits as real money. For example, a £10 bonus with a 30x wagering requirement would need £300 to be wagered before any winnings from the bonus can be withdrawn. 

Kick-Starting Your Online Gambling Experience

Once you’ve signed up as a new UK player, the only thing left to do is play. The best gambling sites will let you use bonuses to explore your favourite casino games and bingo rooms and place bets on sportsbook markets at the best odds available right now.

Why Join the Best Gambling Sites Online?

When thinking about joining a gambling website or the best online casinos, it’s important to understand what you’re looking for. In some cases, it might suit you to join an online gambling site that is specific in what it offers. For example, Buzz Bingo is one of the best bingo sites in the industry and offers free bingo and some awesome no deposit bingo offers.

Whereas, Betfred, Betfair, Betway and William Hill are massive UK gambling websites considered to be some of the best all-rounders online. Let’s take a look at the important factors to consider.

Trust & Safety

Feeling like you can trust a gambling website is vital when you sign up. There are certain factors you can look to for reassurance. For example, how long has the website been operating? Who is the site owned by? What deposit methods do they offer and how big are their customer support teams?

The most important question is whether the site is licensed by one or more leading regulatory bodies like the UK Gambling Commission or the Malta Gaming Authority. To receive and maintain a licence, a gambling site must adhere to strict service guidelines. For example, casino games must be checked by independent auditors to ensure they pay out fairly and use random number generators (RNG) where applicable. All betting sites must also give UK players the option to set time out periods ranging from 24 hours to six weeks. They must also meet the necessary technical standards – firewalls, SSL encryption, etc. – to keep members’ details safe.

All online casino sites and sportsbooks recommended by GamblingDeals are licensed and regulated, so you’ll know you’re in safe hands.

Ease & Convenience

Another factor to think about is convenience. Do you want to spend all of your time jumping between different gambling sites when looking to opt-in to different casino games? Some of the top gambling sites like Mr Green, Betfred, Foxy Casino, and Coral offer you the chance to play across online casino, sportsbook betting, bingo, and slots.

That means you only have to go through one verification process, and you can access everything you need in one place. With that said, you might be missing out on unique casino games, or niche offerings that smaller gambling sites offer.

Managing Your Betting Balance

When you’re thinking about whether to join one gambling site or several, another factor to consider is cash management. When you use multiple gambling websites, you need to manage the process of funding each betting account. Using one gambling site that offers multiple products and longer time limits reduces the need to move funds around. On top of this, you can keep tabs on all your wins and losses in one place, which makes calculating casino cashback and other incentives easier.

Licensed betting sites provide tools to help you manage your gambling. You’ll be able to set deposit limits, which will cap how much you can spend in a given period and activate notifications to alert you when your session has exceeded a set amount of time. You can lock yourself out of an account for days or weeks if you need a break, while longer self-exclusion is also possible.

VIP & Loyalty Schemes

Gambling from one central online gambling site also allows you to make the most of that online casinos gambling incentive and potential VIP schemes. Much like when you first sign up and grab a real money top gambling offer, gambling sites will constantly offer existing UK players new incentives, bonuses, and offers.

In fact, some websites even offer VIP schemes that allow you to get better bonuses and VIP treatment (like access to unique games and better customer service) without the risk of expiry. If you choose to spread your play across a number of gambling sites, the likelihood is you won’t get as much value from existing player bonuses.

Payments & Wallet Management

Managing how you fund your gambling website balance is another important consideration. The best gambling sites online will offer multiple payment options, including debit cards and e-wallets like NETELLER, PayPal, Skrill. 

You may be able to deposit into your account using cash through Paysafecard, a payment system where prepaid vouchers can be bought in physical shops, and the funds then transferred to online accounts using a PIN. There are also Pay by phone options like Boku, which allow you to make deposits by charging the amount to your monthly phone bill.

If there’s a particular method you prefer, it’s useful to double-check that a betting site supports it before you sign up. Currently, we’re seeing that casinos with PayPal are amongst the most popular with UK gamblers, perhaps because of how secure e-wallet payments are, and because withdrawals tend to be faster than other methods.

What are the Different Types Of Gambling Websites?

There are UK gambling sites to suit all interests – whether you’re into spinning slots and roulette wheels, enjoy a spot of bingo, or want to place bets on the footie. Let’s have a quick look at what’s out there.

Online Casino & Live Casino

The best UK online casinos provide a whole selection of classic casino games right at your fingertips. The choice of games can include – but are not limited to – roulette, blackjack and baccarat, and video poker games like Deuces Wild and Jacks or Better. 

Immersive live casino experiences are also available, beaming the action live via webcam from stylish studios across the world. Some live casino games, such as those provided by Evolution Gaming, are highly inventive variations on classics like roulette and blackjack, while others let you play famous game shows and board games for real money prizes.

Slot Sites & Slot Games

As well as offering online casino games, leading gambling sites partner with the best software providers online. That means that they can compete with new slot sites that pop up all the time, looking to steal your business away. Leading slot game makers include Microgaming, Playtech, and NetEnt.

Each of which produces some of the best slot games online – including Age of Gods, Starburst, Cleopatra, Fluffy Favourites, Rainbow Riches, and Eye of Horus. If you are looking to join gambling websites that offer the best slots online then check out our slots section.

Bingo Sites & Bingo Offers

While many all-round casino sites do offer online bingo, niche bingo sites like Bounce Bingo, Bingo Idol, Mecca Bingo and Wink Bingo are often better equipped to meet the needs of proper bingo buffs. They offer no deposit bingo, no wagering bingo, and a lot more besides. 

It’s also worth keeping an eye out for new bingo sites and bingo slot sites. As these are fresh on the scene and keen to grab the attention of potential customers, they can often be highly competitive when it comes to providing the best bingo offers.

Betting Sites & Betting Offers

Finally, if you’re passionate about sports betting, you can check out the best bookmakers in the UK. Top sites like Betfred and Bethard have made their reputations by offering a wide spread of betting markets – both in terms of the range of sports covered, and the kinds of bets it’s possible to make. 

With the best UK bookies bringing features like acca insurance, cash-out betting, in-play betting and, of course, sign up betting offers, you’ll be able to wager in a way that suits you, whenever you like.

Types of Gambling Offers

The next step in choosing the best gambling sites is to find the best gambling offers is to understand the sign up offers themselves. Let’s take a quick look at the most popular form of gambling sign up offer.

Matched Deposit Gambling Offers

Matched deposit offers mean that the online gambling site will match your deposit up to a certain value. Traditionally, they will read something like; 100% Up To £100. This means that you will get deposit bonuses matched to your deposit up to the value of £100. For example, if you deposit £50 to bet on horse racing then you will get a £50 bonus.

The best way to maximise matched deposit gambling offers is to deposit the total amount that is being offered by the bookies. In this case, that would be £100, making your total betting balance £200. However, always be responsible and only deposit what you can afford. Betting responsibly is a vital part of gambling online.

Minimum Deposit Gambling Offers

Minimum deposit offers allow players who are looking for maximum value to get a gambling offer. For example, you might be seeking out minimum deposit casinos that accept a £5 deposit in return for a gambling offer, in this case, you can deposit just £5 and get access to a gambling offer up to £20 or more.

No Wagering Gambling Offers

No wagering offers are another way that the best gambling sites incentive players. Wagering requirements are often stipulated when you take up a gambling offer, meaning you need to wager your bonus and any winnings before they hit your cash balance.

This can be a frustrating process for a lot of players, and so seeking out no wagering bonuses is a great way to ensure that whatever you win is yours to keep.

No Deposit Gambling Offers

Finally, some gambling websites will offer you the chance to grab a gaming bonus on your first bet without making a real money deposit. This means that you do not actually need to deposit any funds to take advantage of a gambling offer.

These offers are not always the most lucrative, but they do allow you the chance to try out the online casino or bingo site for free. And you can always deposit money later to get a better bonus code.

Gambling Bonus Terms and Conditions

As we’ve already touched on, it’s vital to read the full terms when comparing the best gambling deals. Here are some of the key conditions to look out for.

Wagering Requirements

With most gambling offers, you won’t be able to withdraw your bonus winnings straight away. Instead, there will usually be a wagering requirement to fulfil. Let’s say you’ve been given a matched deposit bonus of £100, with 20x wagering attached. This means you’ll have to wager a total of £2,000 before you’re eligible to withdraw anything you win using the bonus.

Time Limits

If you’re tempted to set your bonus funds or free spins aside to use later, be careful. There are usually strict expiry dates on such offers, so double check these to ensure you don’t accidentally exceed the deadline. There will usually be time limits on meeting wagering requirements too.

Minimum Deposits

With the exception of no deposit bonuses, you’ll almost always have to transfer over a minimum deposit to be eligible for a sign-up offer. It’s worth double-checking if there’s an additional, minimum qualifying bet you’ll also need to make.

Game Restrictions

The best gambling offers are often able to be utilised across a wide range of casino games or betting markets. That being said, some bonuses may be restricted to certain games or markets only. Free spins are a prime example, as they’re often limited to a small number of specific slots.

Payment Exclusions

New UK customers at some betting sites may not be able to access welcome bonuses if they make their first deposit through certain payment methods. It’s often the case that welcome bonuses are off-limits if you make your first transfer using Skrill or NETELLER, so this is a crucial thing to check if you intend to bank with an e-wallet.

Mobile Gambling Sites

If you want to join the best online gambling sites via iPhone or Android mobile devices, there are plenty of brilliant bonus offers you can access with just a few taps. Regardless of whether you’re playing online casino games, online bingo, or want to place wagers on your favourite sports, you’ll have all the usual functionality accessible on the go.

Practically all gambling sites have mobile-optimised websites you can access through the browser on your phone or tablet. Many also have mobile apps you can download – these can be even more user-friendly, with push notifications to keep you updated on the best gambling offers.

What’s more, there are specific payment methods that are exclusive to mobile devices. For example, you can link up your debit cards or bank accounts with Apple Pay and Google Pay, to make secure and fast transactions with UK gambling sites.  

Payment Methods at Online Gambling Sites

When it comes to selecting a payment method at new gambling sites, most online gambling sites will offer traditional deposit methods like debit card and bank transfer – credit cards are now banned for UK players. In addition, you will also be able to use e-wallets and pay by mobile casino sites depending on the online casino you sign up with. Cryptocurrencies like Bitcoin and Ethereum are increasingly being accepted at the best betting sites, too. 

Let’s take a quick look at some of the most popular banking methods for players and punters in the UK.

Debit Cards

Using your debit card can be a highly convenient way to deposit and withdraw funds. After all, it doesn’t require setting up any new accounts, and the money will be in your betting account instantly. However, withdrawals can take up to six working days. 

PayPal

Still the most popular e-wallet, PayPal is a highly secure way to transfer and receive funds, as you’ll never have to share sensitive bank or card details. As well as providing instant deposits, PayPal withdrawals are also on the speedy side, with some sites able to process your payouts in 24 hours or less.

Boku

Boku is a pay-by-phone platform that is incredibly easy to use. You simply provide your phone number on the cashier page of the betting site, and the deposit amount will be charged to your next phone bill. The downsides are low spending limits and the inability to make withdrawals using the same method.

Paysafecard

Another way to make an instant deposit is via Paysafecard. You can purchase vouchers online or even in shops using cash and transfer the amount on the voucher to your betting account using the unique PIN. While some sites may allow withdrawals if you have a My Paysafecard account, this remains a deposit-only method at most casinos and bookies.
