Best Casino Bonus Sites: The Definitive Guide

We’ve created the ultimate guide to finding, comparing, and taking advantage of the best casino offers out there right now. Whether you’re looking for online casino bonuses without wagering requirements, free spins, matched deposit bonus offers, or no deposit casino bonuses, our guide to the best online casino offers can help. 

Here’s what we’ll be delving into on this page. 

• How do we find the best casino offers?
• What do all of the best casino offers include?
• What are the best casino offers?
• What are the different types of casino bonuses?

Let’s get started.

The Benefits of Claiming Casino Offers from Casino Bonus Sites

There are numerous advantages of claiming casino offers for UK customers. Of course, every player is different and will benefit from different aspects of such bonuses. It’s therefore helpful to research the main types of promotions before signing up with a site, in order to get the most out of the rewards.

Below, check out some of the main reasons to claim free bets and other lucrative rewards from casino bonus sites. 

• Chance to win real money — Rewards such as free spins and bonus credit regularly feature in casino welcome bonuses and give you the chance to win real money without having to stake your own cash. What’s more, if you opt to play with a no wagering bonus, you’ll have a much better chance of being able to withdraw your bonus cash later, as wagering requirements on casino offers can be quite restrictive.

• Getting to grips with a site — Playing with rewards from casino offers gives you the chance to test out a site and see if you enjoy the experience. If you initially play with bonus credit from a no deposit offer, you can try a casino without depositing any funds at all. With such a range of casino sites to choose from, it’s worth taking the time to ensure you’re happy with all aspects of the site, such as customer service, navigation, and payment options.

• Trying out new games — Casino bonus sites typically host hundreds of games, so players are spoilt for choice. However, it can take time to get up to speed with a new game. A great use of a casino welcome bonus is to try out some new games you wouldn’t normally play. It also gives you the chance to practice before playing with your own money.

Disadvantages of Casino Offers

• Only available on selected games — One of the main terms and conditions attached to free bets for UK customers is the eligibility of games. Thankfully, the selected games on casino offers tend to be popular fan-favourites such as Starburst by NetEnt and Book of Dead by Play’n GO. Nevertheless, it’s always a good idea to check out the eligible games and see if you like the look of them before committing to a casino offer. 

• Can only claim a casino welcome bonus once — Casino welcome bonuses are typically the most lucrative promotions available to players, as operators compete to attract new customers. Common rewards include free spins and deposit matches where you’ll receive bonus credit. However, a welcome bonus is a one-time offer to new customers that can’t be claimed again. 

Additional restrictive terms and conditions — Bonus terms and conditions are usually quite extensive and go beyond which games you can play. There is often a maximum win cap that limits your prize money. A similar restriction is the value of the free bet, which is usually capped at a game’s minimum bet.

How We Find the Best Casino Offers Online

Finding the best casino offers around is never an easy task. However, here at GamblingDeals.com, it is what we do each and every day. That means you can quickly browse our new UK online casino offers tables to find the best casino deals and online casino sign up offers in the business.

And it all starts by focusing on the critical factors that make up the best casino deals online. We will dive into a lot more detail shortly, but finding the best casino offers means focusing on two aspects, firstly the casino site itself, and secondly the casino deals being offered.

Our mantra is that we want to send you through to play at the best casino sites. It doesn’t make much sense referring you to an amazing casino offer if you can’t use it to play the casino games and slots that you enjoy. Likewise, we want to show you the casino sites that value your business by incentivising you with the best online casino offers around.

To make sure that we get it right, we always follow our casino offers UK checklist. Not only does this mean we bring the best online casinos, like Betfred Casino, Mr Green, Foxy Casino and Gala Casino to your fingertips, but it means your guaranteed to get their best casino offer available when you sign up.

Casino Offers UK Checklist

Each and every time we find you the latest casino offers from the best casino sites, these are the critical factors that we look for:

Casino Bonus Sites Checklist

• Trustworthy – we check to make sure that the site offering casino deals is trustworthy by looking into its operating history, who it’s owned by, and whether there have ever been any legal disputes about its operating practices;
• Regulated with proper licensing – we make sure that the casino site holds a licence with the UK Gambling Commission. This means the casino must adhere to the gaming authority’s strict regulations, allow its games to be audited for fairness by independent testers, encrypt all customer transactions, and provide players with tools to curb problem gambling habits;
• Range of gambling products – how expansive is the casino site’s offering? We carefully assess the categories of products you can explore once you’re a member, including slot games, table games, and live casino experiences, not to mention bingo, video poker, and sports betting;
• Casino software partnerships – the best casino sign up offers should let you use your bonus funds and online casino free spins UK on the top games out there. That’s why we like casino sites that work with top game makers like Playtech, Microgaming, and NetEnt who pull out the stops when it comes to creating the most immersive iGaming experiences around;
• Slot games – we know that real money slots are a huge draw for online casino players. Our experts pay close attention to the size and diversity of the slots libraries at UK casino sites, checking to see if there are modern classics like Starburst and Book of Dead as well as the latest titles and potentially lucrative progressive jackpots;
• Live casino games – another super important thing we look out for is the availability of live casino games. Some players love to play live casino, and it’s a key reason why they take up casino offers. If a site makes its welcome bonus available for live casino titles, we want to tell you about it;
• Payment methods and withdrawal options – does the casino site offer flexible and trusted payment methods, including debit cards and e-wallets like PayPal, Skrill and Neteller? That’s another key question our experts ask when reviewing sites. Note that credit cards are no longer valid at licensed gambling sites as of April 2020;
• Customer support – we like to see casino sites offering strong customer support options. Ideally, members should have a number of ways to reach out to staff, such as by email, online live chat, and by phone. We also dish out extra brownie points if customer support is available around the clock.

Once these things have been established, and we know that the casino sites are worth your time, then we look at the best casino offers available. Here’s a snapshot of our bonus offer checklist.

Casino Offers Checklist

• Type of casino offer – is the casino offering a matched deposit bonus, such as Aspers Casino’s 100% up to £100 deal? Perhaps there’s an online casino no deposit bonus, like the £88 free play credits which new customers can claim at 888 Casino? We’ll lay out what’s on the menu so you can pick out the best casino offers for you;
• Value of the casino offer – how much is the casino site offering in terms of a bonus? This can vary a great deal from site to site, and some can offer sizeable deals. An example is Playzee, which provides a matched deposit of 100% up to £300 for new members;
• Added benefits – does the offer for new players come with added incentives like free spins, casino cashback, or bingo site tickets? These kinds of bundled casino offers are pretty common, which is great news for bettors. Take Casino Lab’s welcome package, which features a matched deposit of 100% up to £100, plus 100 free spins;
• Wagering requirements – what are the wagering requirements? How severe are they, and is it realistic that you can turn your bonus funds into real cash? We’ll highlight what the requirements are for different casino offers, making it easier to pinpoint low wagering deals like Grosvenor’s ‘Deposit £20, Play with £50’ welcome bonus package, which has a very player-friendly 5x wagering requirement attached;
• Terms & Conditions – are the terms and conditions of the casino offer clear and concise? Do they clearly stipulate what you’re signing up for, and if there are any max or minimum requirements? We check whether this is the case, and also make sure that the online casino follows begambleaware.org guidance.

Once we are happy that the online casino offer adds enough value for you, then we’re ready to show it in our online casino deals tables. This is where we try to max out the value for new players with the best bonus offers around.

The Different Types Of Online Casino Offers

Now that we have covered some of the best casino sign up offers and welcome packages around, let’s take a look at the various types of casino deals and how they differ.

Matched Deposit Casino Offers

The most common casino deal is the matched deposit. With these offers, casino sites match a certain percentage of your deposit when you first sign up, so you get a matched bonus amount to wager in the casino when you’re getting started.

For example, you might see something like the below:

• 100% Bonus Up To £200

Here, depositing £100 will mean you get an extra £100 sent straight to your bankroll. As it’s capped at £200, any amount you deposit exceeding this won’t be matched. In other words, if you deposit £1,000 you’ll still only get the £200 bonus. Some of the very best casino sign up offers go further with the percentage, with matched deposits as high as 200%, 300%, and even 500%. These are ideal for high rollers who want to maximise their bankrolls and don’t mind satisfying the correspondingly steep wagering requirements to obtain their winnings. 

One of our top recommended sites for matched deposits is Royal Slots. Its welcome offer gives you the potential to rack up £1000 in bonus funds – a pretty significant boost.

No Deposit Casino Offers

The next type of deal is a no deposit casino bonus. This will reward you with funds just for signing up, with no need to transfer your own money over. These casino sign up offers can look like this:

• £10 No Deposit Bonus

This means that when you sign up, you’ll get £10 added to your betting balance without needing to make a deposit. What’s more, some online casinos will offer free spin no deposit bonuses, so you can spin the reels of top slot games like Rainbow Riches, Starburst, Cleopatra, Age of Gods, and Twin Spin without having to risk your own funds.

Like everything in life though, nothing is free. No deposit casino deals are often harder to find and can come with tougher wagering requirements. 

A great no deposit bonus can be found at Paddy Power Games, which lets new members claim 100 free spins on selected daily jackpot slots, just for signing up. The best bit? There are no wagering requirements, despite this being a no deposit offer.

No Wagering Casino Offers

As you might guess, no wagering casino offers give you the chance to play at new casinos without having to worry about wagering requirements. In fact, whatever you win when playing with a no wagering bonus is yours to keep. Let’s take a look at a quick example where bonus wagering does not apply:

• £100 Casino Bonus With No Wagering

This means that anything you win using your bonus funds can be cashed out straight away as real cash. Unlike match bonus offers with wagering requirements, you don’t need to worry about game weighting on eligible games, or deposit match terms on your max bonus bet.

PlayOJO is known for these kinds of casino deals, and it currently offers new customers 80 free spins on the popular Book of Dead slot. The freebies are yours if you make a minimum £10 deposit, and there’s no wagering on anything you win.

Free Spins Bonuses

Whenever you take up free spins casino offers, you’ll be able to try out select slot games with no risk to your own funds. Typical free spins bonuses for UK players will look something like this:

• Get 50 Free Spins on Book of Dead

Here, you’ll get 50 free spins to use when you first sign up and make a minimum deposit. Regardless of your max bet, you can enjoy video slots gameplay and get better spin value just for taking up a free spins casino offer.

Free spins are widely offered as part of welcome bonuses. A great example is the sign up package at Fruit Kings, where making a first deposit of at least £20 will unlock a matched deposit bonus along with a generous 100 free spins.

Reload Bonuses and Ongoing Casino Promos

Online casino offers aren’t just for new customers. The best UK sites also provide bonuses on subsequent deposits, known as reload offers or reload bonuses, to make existing members feel valued and giving them an incentive to return. Reload offers can take the form of matched deposit bonuses, free spins, and cashback offers. 

One of the top providers of ongoing promotions is Playzee, which has different deals every day of the week. For example, its ‘Crazee Tuesday’ offer gives you back 10% of any losses you’ve had in the previous week. Meanwhile, the ‘Lazee Wednesday’ offer provides a 20% up to match if you make a min deposit of £20 that day.

Referral Offers

Some online casino deals can provide you with benefits just for recommending the site to people you know. Take Paddy Power Games, for instance. This top UK casino site has a scheme in place where you can earn £20 in cash if you refer a friend. All you have to do is provide your friend with a unique referral link. Then, when they sign up and make a minimum £10 stake, you’ll get your £20 reward. You can earn even more by referring more friends, up to a maximum of five in a given month.

Wagering Requirements on Casino Offers

One thing to be aware of when you take up the best online casino deals is that they will often come with wagering requirements, sometimes known as playthrough requirements. This means you’ll have to wager the value of your bonus, and sometimes the bonus plus the value of your initial deposit, before you can withdraw any profits. The concept can be a little tricky to get your head around at first, so let’s go through it.

Let’s say that you take up a £100 casino offer with a 30x wagering requirement. To meet the terms of the bonus, you’ll have to place £3,000 in wagers in order to withdraw anything you win with the bonus funds.

Wagering requirements are applied differently to free spins. Instead of using a nominal value, the wagering requirements are multiplied by your free spins winnings. For example, if you won £10 with your free spins at 35x wagering, you would need to wager £350 to make a withdrawal against the bonus winnings.

Other Types Of Online Casino Bonuses

Much like matched deposit bonuses and no deposit casino deals, there are other types of casino offers that are also worth considering. The best casino offers are available across the gaming suite, meaning you can use them to play live casino, slot games, and other top casino incentives.

Let’s dive in and take a look at some of the other ways you can enjoy the best online casino offers.

Live Casino Offers

While the types of casino offers don’t change much in the live casino space, many top casino sites will offer specific live casino offers. This means you can get a unique set of casino deals that are made especially for live casino play.

The great thing about this is that many casino bonuses and promo codes discount live casino play because the chances of winning on a live casino table are higher (on average) than they are when you play online slots.

As such, casino bonuses tend to have stipulations connected to live casino offers that mean to play on those tables only counts a small amount towards meeting wagering requirements.

Don’t worry though, if you are a live casino player there is a great chance of picking up an amazing UK casino offer.

We have a page dedicated to the best live casino offers, so head over and check it out. However, for a quick snapshot, this is what a live casino offer will look like:

• Get a live casino 100% up to £100 matched deposit

Like other casino deals, you can deposit up to £100 to get a matched deposit bonus. However, the bonus is specifically designed to be played in live casinos like Genting Casino, Grosvenor Casino, and Aspers Casino.

These live casino powerhouses dial you directly into their live tables where you can play the best live roulette, blackjack and baccarat action.

Casino Cashback Offers

Finally, you can also grab a unique casino deal called a casino cashback offer. Unlike traditional casino bonuses, casino cashback offers give you the chance to earn cashback on your losing bets. Leading casino sites like All British Casino, Bingo Idol, No Bonus Casino, and others pay up to 10% of your losing bet back into your real money balance.

That means if you hit a losing month and end up £1,000 down, then you will get £100 paid back into your betting balance as cash-out balance. Not bad eh? Here at GamblingDeals.com, we are the number one casino cashback site online and have our own VIP scheme which gives you access to a selection of exclusive casino cashback deals.

Casino cashback deals will look something like this:

• Get 10% cashback on your losing bets

As we have run through, this is one of the best casino offers around for anyone who wants to protect their bets with the chance to get a percentage back in the event of a losing month.

What’s more, you won’t need to worry about withdrawal restrictions, deposit amounts, playthrough, or bonus cash. Whatever you win regardless of you claim back in your bonus balance is yours to keep.

Bonus Codes

Sometimes online casinos offer bonuses through promo codes. These may be displayed on the site’s home page, in marketing emails, or on TV ads. All you need to do is add the bonus code to the relevant field when making a qualifying deposit, and the bonus will be credited to your casino wallet. This kind of bonus could take the shape of extra spins or free cash, but of course you should bear in mind that terms and conditions will apply. Wagering requirements, time limits, wagering contributions and more could be factored in, so be sure to read the T&Cs before you opt-in.

Where Can You Find New Casino Offers?

Finding new casino offers is a breeze on GamblingDeals.com. We spend a lot of time scouting out the best new slot sites and new casinos, meaning we can put the best new casino offers at your fingertips. And the great thing is, there are always new casinos looking to grab your attention.

These include top casinos like Volt Casino, Rizk Casino, Playzee and Hyper Casino, all who have launched in the last few years to disrupt the traditional casino space.

Something that we have noticed when it comes to new casino offers is that they include unique benefits. For example, Volt Casino offers the chance to earn free Volt Spins and Volt Coins to build your own virtual city, while Playzee gives you the chance to earn Zee coins.

If you are looking for a new way to play, in new casinos that offer something a bit different, it’s well worth checking out the best new casino offers around.
