Best Casino Offers for 2021:

How to Choose the Best Casino Bonus?

When you’re on the lookout for casino offers, you must make your choice of gaming platform from among the best UK casinos. You can do so by reading fair, unbiased online casino reviews, such as the ones we have published on our site. And that way, you can be sure that you’re genuinely choosing the best casino offers available. Things to look out for in particular include, first and foremost, safety. The best UK casino must have a proven reputation, must hold an active UKGC license, and should use adequate safety technology. Then you can move on to consider things like game selection and available payment methods.



Safety is always at the forefront of online gaming and any site that handles sensitive information. Hence, online casinos must use encryption technology to protect their users’ private details. And in addition, it’s always good to see that casinos are involved in responsible gaming, which shows they can provide a safe environment for players.



Licensing is another vital factor when considering online casinos. All gaming sites need to hold a valid license issued by the UK Gambling Commission in order to offer their services to UK players. So make sure that’s the case with the casino you’re considering. And it certainly won’t hurt if there are additional licenses present, as well.



The game selection of the online casino is also of importance. After all, the main reason you are even at the casino is to play the games there. So make sure the library offers a rich enough assortment of different game types. And it’s a good idea to note any titles you already know and enjoy playing.

Payment Methods


Last but not least, the payment methods listed at the casino need to include options that work for you. Furthermore, those options need to be available both for deposits and withdrawals. And be sure to note any potential fees and what the time frames are.

How to Claim Casino Bonus Offers?

Claiming the best casino deals is no difficult feat. All you have to do is decide on the exact bonus you would like to take advantage of. And then, you also need to ascertain that the casino offering it is safe and trustworthy. You can check out our list of best UK casino offers to see if any of them catch your eye. Once you’ve narrowed your options down, it’s essential to read through their terms and conditions. That way, you will know what potential limitations there are, as well as whether or not the wagering requirements are reasonable to you.

From that point on, all you have to do is register an account at the casino of your choice and claim the said bonus. After that, you can start playing. And as you do, you will need to complete the wagering requirements to clear the bonus. Here’s what that will all look like in step-by-step format.

1. Choosing the Bonus. What bonus you choose will depend on your gaming preferences, so be sure that the bonus can accommodate those.
2. Check Terms & Conditions. It is crucial that you are familiar with the bonus terms to make sure you are indeed eligible for the exact offer.
3. Check Wagering Requirement. The wagering requirements are essential for any bonus, and these will help you determine whether or not it would make sense for you to go after a particular promotion.
4. Account Registration. Next, all you have to do sign up at the casino you’ve chosen by using your email address and personal details.
5. Claim the Bonus. After you’ve registered your account, take the steps necessary to claim the bonus (e.g., make a deposit, enter a bonus code, etc.).
6. Clear the Bonus. Once you have received the casino bonus, you will need to start completing the wagering requirements in order to cash out your winnings.

Online Casino Offers – Different Types Explained

Casino offers these days come in a plethora of shapes and sizes. And they can vary depending on a handful of various factors, such as the target audience, as well as the game types they’re intended for. For instance, certain casino promotions may be designed to promote a specific game, such as a slot game. And in that case, they may be offered in the form of free spins only for that particular title.

As far as the target audience, gaming sites usually distinguish between new and returning players. For example, some of the best online casinos offer a great variety of welcome bonuses. Hence, they cater to new customers and aim to incentivize them to register at the casino. Alternatively, casino bonuses may be part of the online gaming platform’s loyalty program. And in this case, they will be aimed at existing players and may be handed out as rewards for achieving a new status in the program, for example.

Casino Welcome Offers

Casino welcome bonus offers are arguably the most common type of promotional offers in the iGaming world. They also happen to be among the most attractive. And if you have a look at our selection of the best online casino sign up bonus offers, you will see why that is. Typically, they will feature a rather significant cash bonus available for play, although they don’t have to. There are also various kinds of welcome offers, such as deposit and no deposit bonuses. They can be given as bonus funds, or they may be credited to players as free spins, for instance. And frequently, you can even find a combination of both.

Best Casino Deposit Bonus

If you’re interested in exploring the best casino deposit bonus offers, you will notice these, too, can vary enormously. For example, some of the best casino bonus with deposit promotions feature a 100% match bonus. This means that the casino will match the size of your deposit with bonus funds. But you can usually also find offers that go beyond that. For instance, it’s not uncommon to see deposit bonuses of 200%, 300%, and even up to 500%. Hence you can enjoy up to double, triple, and up to five times the worth of your deposit as bonus money – on top of your deposit.

Deposit Bonus Types:

100% Deposit Bonuses

200% Deposit Match Casinos

300% Deposit Bonus for Slots

➞ 500% Deposit Offers

➞Deposit 5 Get Free Spins

➞10 Pound Deposit Slots

➞Deposit 20 Get Bonus

Casino Reload Offers

Casino reload bonuses constitute a significant section in the world of gaming bonuses. This is because, in addition to attracting new players, gaming sites need to retain their existing ones, as well. And that’s where the casino reload bonuses come in. These types of promotional offers allow players to claim bonuses on their subsequent deposits (i.e., not their first deposit). As a rule, these will be of a smaller size than the welcome offer. For example, it’s common to find 50% match bonuses in such promotions. But that doesn’t necessarily have to be the case, and it all depends on the casino.

Casino Cashback Offers

Casino cashback offers are a type of promotion that is aimed at existing players at the casino. Moreover, cashback bonuses cater to players who have already spent some time and money at the casino. And, most importantly, it’s for players, who’ve already accumulated some losses, as well. Hence, by definition, the casino offers to reimburse them to a certain extent and, thus, encourage their players to keep playing. It’s a nice gesture, as well, because being on a continuous losing streak can certainly be disheartening. And a good cashback bonus may be precisely what you need to cheer you up and make up for some of those losses.

Casino Loyalty Programs

Loyalty bonuses are a very popular means of ensuring players are motivated to keep playing at the same online casino. And the way they work is they offer various loyalty casino bonuses, depending on the progress you make within the rewards program. For example, by playing at the casino, you can climb the ladder in the loyalty program and achieve new levels over time. And with each new level, you can unlock bigger and better perks at the casino, quite possibly also including cash bonuses. And the higher levels of such programs can even provide players with various exclusive extras, such as special event invites, and so on.

Live Casino Bonus

Sometimes online casinos may offer bonuses intended explicitly for their live dealer games. This makes sense because there are players out there who particularly enjoy the authentic atmosphere of land-based casinos relayed in these live dealer titles. And hence, the bonuses cater to a select audience. Besides, live dealer games often attract high rollers, as the limits are much higher than what you can find in regular RNG titles. For instance, some tables can allow stakes of way up in the thousands. So it’s not uncommon to see much larger bonuses in live dealer promotions, as well.

Slot Bonuses

Slot bonuses, as you might be able to guess, are casino promotions oriented toward slot players. They can often be included in welcome packages and seasonal or recurring promotions at the casino. And they can just as well be offered upon player deposits, as well as granted without any deposit being necessary. It all depends on the exact type of promotion they are part of. But one thing they all have in common is that they are given in the form of free spins because they are intended to be used in slot games.

Blackjack Bonuses

Blackjack is one of the most played types of casino games. So it’s only logical that casinos would offer different bonuses for the classic table game. And it’s not only a matter of catering to a specific kind of player, although that’s also part of it. It also has to do with wagering requirements that are often different for table games.

Roulette Bonuses

Being among the most popular casino games since the dawn of time, the roulette section of the casino always has plenty of players flocking to it. And with roulette having its specifics compared to other casino game types, online gaming platforms frequently run promotions exclusively for roulette players.

Free Spins Bonus

Free spins bonus offers are a type of promotion intended for online slot games in particular. And when it comes to casino bonuses that include free spins, UK players have a sea of options to choose from. Like with some of the other bonus types out there, free spins bonuses can also be quite versatile. For example, they may be offered upon deposit, or they may simply be granted on registration. And as a rule, the free spins bonus will be meant for a specific title, or maybe even a selection of titles.

No Deposit Bonus

One of the particularly attractive types of casino promotions out there are the no deposit bonus offers. As the name suggests, no deposit offers don’t require players to deposit to claim them. Instead, depending on the terms of the exact promotion, they can be claimed by simply registering at the casino or otherwise fitting into the bonus’s eligibility. Furthermore, no deposit bonuses can be offered in various forms. For instance, while it’s very common for casinos to grant them as bonus funds, they can just as well provide them as free spins.

VIP Bonus

If you are a member of the online casino’s loyalty program, which is often also called VIP club, you may be entitled to specific bonuses. We call such types of promotions VIP bonuses for this reason. And they can be offered based on, for instance, achieving a new status in the loyalty program, etc.

Daily Bonuses

It’s common for online gaming sites to run recurring promotions, and some of these may even be on a daily basis. This means that players can take advantage of a casino bonus every day, as long as they meet the requirements that make them eligible for the offer in question.

Casino Raffles

Raffles are always loads of fun, and they serve as an excellent enhancement of players’ experience at the online casino. The rules of the raffle and who can participate in it may vary tremendously from casino to casino. But the bottom line is that players can win all sorts of prizes, from bonuses to vacations and beyond.

Referral Bonuses

Online casinos are always looking for a way to attract new players, and referral bonuses serve precisely that purpose. They act as an incentive for players to invite their friends or people they also know to join the casino. And in return for that, they can receive a bonus.

Low Wagering Bonus

Most online casino bonuses have wagering requirements, so it’s always ideal to seek bonus offers with lower wagering requirements. This makes it easier for players to turn over the bonus in time and release their winnings before they expire. Hence, there are low wagering bonuses out there that can even be labeled as such.

No Wagering Bonus

While the vast majority of casino bonuses need to be wagered in order to be able to cash out your winnings from them, there are bonus offers that don’t have such requirements. This makes them especially attractive because whatever you win using the bonus is yours to keep right away.


Freerolls are a type of promotion aimed at poker players. The idea behind them is that they provide players with free entry into a poker tournament, which, in a way, is also a kind of bonus offer. Such promotions may target new players, as well as cater to existing players.

Comp Points

At online casinos, comp points are a way to reward returning players for playing at the site. As you play the various casino games, you accumulate points. And later on, the casino offers to exchange those points for various prizes or simply convert them to cash.

Tips for Casino Promotions

Of course, casino promotions need to be fair and revolve around games that we like to play. But in order to truly make the most of them, there are things that players can do on their part as well. For instance, it’s important to coordinate the wagering requirements of any bonus offer with your own gaming style.

If, for example, you tend to play table games more than anything else, then bonuses that favor slots for the completion of their wagering requirements may not be such a good idea for you. Also, it helps to note the exact games the bonus is intended for. Some casino offers, especially no deposit ones or free spins bonuses, can often be tied to a specific title. So if you’re going to maximize your gain from the bonus, you will want to make sure that you actually enjoy playing that said title.

Terms and Conditions for Casino Bonuses

All casino bonus offers have their own terms and conditions. Here is where you will find all the necessary information related to what makes players eligible to claim the offer. And it’s also where you can learn about any limits that may apply to the online casino promotions in question. Usually, these will have to do with the wagering requirements, but they may also revolve around game availability, time restrictions, and so on. Hence, in order to be sure you’ve found the best online casino bonus for yourself, it’s vital that you thoroughly read its terms and conditions first.


For the most part, all bonuses have some validity to them. And it’s only natural; otherwise, players won’t really have the motivation to turn the bonus over and play the games at the online casino. For this reason, players will usually have a limited amount of time to meet the wagering requirements.


Not all bonuses are made the same. Some might be used on all games, whereas others may only be available for a select few. The same is also true for the games in terms of their contribution towards fulfilling the wagering requirements. So it’s essential to know the contribution weight of all game types.

Minimum deposit

If the bonus offer you are looking to claim is a deposit bonus, you will need to consider what deposit amount eligible for said offer. So once you’ve ascertained what that amount is, you will need to deposit that same amount or more in order to receive the bonus.

Wagering requirements

The wagering requirements in the terms and conditions will tell you exactly how many times you need to roll over (stake) the bonus. Meeting these requirements is necessary in order for players to free their winnings and be able to withdraw them.

Wagering time limit

While the wagering requirements will tell you how many times you will need to stake your bonus, they may also have a time limit. Namely, players will need to fulfill these requirements within a fixed time. And failing to do so will usually result in the forfeiture of all bonus funds and winnings.

Time limit

Sometimes the bonus received may only be valid for a certain time. For example, this very common with free spins offers that may only be active for 24 hours. And in this case, players will have 24 hours to use the free spins before they disappear.

Max Bet

Often there may be a limit on the amount you are allowed to stake per bet. This is done in order to prevent players from meeting the wagering requirements immediately. After all, it’s about getting you to spend some time at the online casino, as well.

Win limits

Especially when it comes to no deposit or no wagering bonus offers, there may be a cap on the amount you can win from them. This is a common practice to prevent the house from losing too much cash on such promotions, so it’s something to keep in mind.

Online Casino Wagering Requirements

Most bonuses you will find these days have their online casino wagering requirements. And casino bonus wagering requirements exist for two main purposes. One is that the casinos don’t end up simply throwing their money at people and, as a result, suffering losses. And the other actually goes hand in hand with the purpose of the bonuses offered at these casino sites. Bonus offers, for the most part, exist to attract and retain customers.

Hence, the bonus may bring in new players. But the wagering requirements will ensure that players stay long enough to get a good feel for the casino. The end game is that the players will actually have an enjoyable enough experience to want to come back more often. As for the wagering requirements themselves, these are the number of times you will need to stake your bonus. Sometimes they may apply to the bonus and winnings, sometimes to the bonus and deposit, for example. That will depend on the particular offers and their terms. But the bottom line is that you need to meet these requirements in order to be able to cash out your winnings.

Game Contribution Percentage

Once you have claimed your bonus and can start working your way to meeting the wagering requirements, you will want to know which games best serve that purpose. What that means is that not all games will have the same contribution weight for the wagering requirements. For example, most slot games will usually have a 100% contribution. And that means that 100% of your stake in a given slot game will count towards the bonus turnover. Alternatively, there may be games with a lesser percentage and even no contribution whatsoever. So those games are best to avoid as far wagering requirements go.

Wagering Calculator

Sometimes it may feel like the wagering requirements are complicated and confusing. However, calculating the amount you need to wager is actually very easy. And the first step towards doing this yourself is finding out from the bonus terms whether the wagering is applied to the bonus or the bonus and deposit amount together. From that point on, it’s just simple math.

Say you have a 100% deposit bonus for depositing £50. And the wagering requirements are x35 for the bonus amount only. In that case, you will have to stake £50 x 35 times = £1750 to meet the wagering requirements. And if you had the same kind of 100% match bonus for your £50 deposit, only the wagering requirements were x20, and they were meant for the bonus + deposit:
(£50 + £50) x 20 = £2000.

Of course, you can also use our free bonus calculator to double-check your results.

Best Deposit Bonus Payment Options

The best deposit bonus payment options will vary from player to player. Everyone has their unique preferences based on what’s convenient for them. However, there are a few things that remain universally true for online casino payment methods, regardless of preference. One is that even the best casino bonus with deposit offers may have a restriction on the payment methods you can use to claim the bonus. It’s not you – it’s them. Nevertheless, it’s important to make sure you aren’t using any of these restricted processors, so you don’t end up disappointed later.

And then the other critical point to make about payment methods in the context of online casino offers has to do with withdrawals. As you may already know, not all payment methods at online casinos are available both for deposits and withdrawals. And with that in mind, it’s best to make sure you can cash out via the same method you used to deposit.

Most Used Payment Methods

If you browse through a fair amount of online casinos, you may notice that certain payment providers tend to stick out more. For example, lately, PayPal online casinos have gained a lot of momentum since the e-wallet began to work with gaming sites. And if you’ve happened to come across a Trustly casino, UK players are starting to use this method, especially often, to fund their accounts.  Both of these payment methods are very fast and easy to use. But in addition to that, they also have a reputation for offering exceptional levels of safety.

Restricted Payment Methods

At times, it may happen that you run into a bonus offer that has restrictions on certain payment methods. The reasoning may be different from bonus to bonus and in regards to the individual payment provider. For example, Boku is a convenient and accessible payment processor. And Boku casinos these days are especially popuar. However, due to the way it’s structured, Boku cannot accommodate withdrawals. And it’s a similar story with a handful of other providers like in the case of Apple Pay casinos. And since as part of general safety procedures, withdrawals need to be requested via the same method used to deposit, these providers may fall under bonus restrictions.

Casino Bonus Codes

Some bonuses at online casinos may come with a code. This may seem like a bit of an extra step sometimes, but actually, there are several good reasons for different promotions to have their separate codes. One is that certain players may not wish to receive a bonus when they register at the casino, for instance. Hence, they shouldn’t have to take any extra action in order to refuse the bonus.

And, on the other hand, players who do wish to take advantage of the welcome offer can do so simply by entering the bonus code when registering. Another reason for there to be bonus codes is when the online casino is running several promotions at a time. So if, for instance, there are several different deposit bonuses on offer, you’d need to specify which of them you would like to claim. And that is done with the help of bonus codes.

Mobile Casino Offers

With mobile gaming having gained so much momentum over the last several years, mobile casino offers have become synonymous with regular casino offers. That’s because casinos these days strive to make their sites and games compatible with various mobile devices. We have shortlisted some of the best mobile casino UK platforms that you can have a look at to see how well they fit into any screen size.

Hence, whether you’re interested in playing mobile slots, live dealer titles, or any other casino games on your smartphone or tablet, you can do that. And you can use any bonus you’ve claimed as a mobile casino bonus all the same. There are rare exceptions of games that haven’t been optimized to fit smaller screens, however. And in the event that you’re set on playing a specific title, it may be a good idea to double-check that it’s available on mobile.

Why do Casinos Give Bonuses?

The end game of any bonus or promotion offered at an online casino is to better its business. But if you break it down, casino bonuses essentially serve two purposes. One is that they are intended to attract new players (i.e., welcome and sign-up offers). And the other is to retain existing ones. That is why you have recurring promotions, reload bonuses, and similar types of offers. Bonuses are a great incentive for players to explore the casino’s library and stick around for longer. And if they like what they see, they can then choose to keep playing at the same casino.

Jonathan Cortis was an avid online casino player. He had already been sharing and discussing experiences with a group of like-minded friends that had the same interest. And so it seemed only natural to take a fun hobby to the next level. Jonathan decided to create a website where he and his friends could publish reviews of the casinos they've played at.
