What Is a Casino Bonus?
An online casino offer is probably the most influential factor in determining whether or not a new customer registers with that platform or decides to go with a competitor. Casino promos are classified as free money or rewards that you will receive when you register an account as a new customer.
Why Do Online Casinos Offer Bonuses?
Online casinos are willing to offer players free rewards to get them to sign up and play on their platform and then continue to play regularly. This is in the hope that once the sign up casino bonus funds run out, the player will then play with their own funds. As for players, this is great because you can try out new online casinos and casino games risk-free. Some UK welcome bonus offers are more generous than others, so it is about deciding which one you will use the most and which one suits your tastes and preferences. From the casino promo funds, you can still win money as well. So there really isn’t a reason why you shouldn’t claim a casino sign up bonus as a new player. Not to mention that once you are signed up, you can then take advantage of the existing player offers. If you like the idea of getting something for nothing, then we highly recommend you choose one of the welcome bonus offers from the list above. You can claim as many casino promotions as you wish, and most of them have small minimum deposit amounts too! The bonus funds will differ from casino to casino. Choose which one is best suited to you and your playing style. You can use our expert reviews to help you make a decision. We only share trusted online casino promotions with you and would not list an online casino that is not regulated. This is to ensure that you can trust these platforms to handle your billing information and be true to their word in rewarding you with casino bonus funds.
Types of Casino Promotions
The best online casino bonus offers come in many different forms. This is because not every player has the same wagering style or enjoys the same types of casino games. So that online casinos can target all players, there are different bonus types that have to be wagered in a certain way. We’re going to look at these types of online welcome bonus offers so you can decide which one would be best suited for you.
No Deposit Bonuses
No deposit bonuses are a rarity in the gambling world, which is why you should snatch this offer up if you ever come across one. They are exactly what you think they are, casino bonuses that are rewarded to you without you having to make a single deposit.
Cash Offers
Typically, these casino bonuses will be quite small, perhaps within the region of GBP 5 – GBP 20. This means it will run out quickly when wagering with it, but there’s still an opportunity to make bonus winnings with it and experience part of the platform before depositing your own money there. Of course, if you decide you don’t like the platform, then you haven’t committed to anything to it, and you can play somewhere else. Here are some examples of the best no deposit bonuses that online casino bonus sites have available:
- GBP 5 free no deposit casino bonus
- GBP 10 free no deposit casino bonus
- GBP 20 free no deposit casino bonus
One thing to note is that usually, the more rewarding the casino promo funds, the stricter the terms are, so be aware of that before jumping straight for the one that pays the most.
Free Spins
No deposit free spins are one of our favourite types of online casino bonuses. They are, in our opinion, one of the best casino promotions out there. Free spins are very popular amongst slot games, and a lot of online casinos can get really rewarding with these casino promotions as they see them as a more preferred choice of reward as opposed to cash bonuses that can be used anywhere on the platform. A casino will offer a certain amount of free spins to players that can be used on slot machines. In some cases, they can be used on any slot game that the casino has in their library, whereas some list specific game titles that you have to play. If that is the case, don’t worry because normally, the game titles are exclusive or brand-new casino games that are very popular. You can use the free spins to create bonus winnings and access bonus features within the slot games. Also, there’s no limit on how many free spins a casino will offer either. We’ve seen some platforms offering up to 400 free spins! This is huge, as you’d expect to land some big wins from this many spins. You can also find free spins being added onto deposit bonuses, allowing you to have a cash bonus to use on casino games and then also get free spins on top of that to use on slot games, so you get the best of both worlds. Once you make winnings from the free spins bonuses, all you need to do is comply with the wagering requirements to be able to withdraw what you’ve won. Most players hate wagering requirements, and for good reason.
Deposit Bonuses
Possibly the most common type of casino promo has to be deposit bonuses. They are the main bonus type that UK customers are looking for. Deposit bonuses are offers that require you to make a deposit, and the casino will reward you with casino funds depending on how much you have deposited. A perfect example of this is a 100% matched deposit online casino bonus up to GBP 100. From this example, a casino will match whatever amount you deposit, up to GBP 100. So if you deposit GBP 100, you’ll get an extra GBP 100 to play with, meaning you have a total of GBP 200. Like all bonuses, it’s a great way to play and win more for free and try out new casino games that you possibly wouldn’t play if you were using your own funds.
Welcome or First Deposit Bonus
Welcome bonuses, or first deposit bonuses, as they are also labelled, are typically the most rewarding you will ever get on a casino site. The reason for this is that this is the bonus that new customers will see and decide whether or not to try that particular casino. If a casino has a really poor welcome bonus, they simply don’t get the custom and the new potential player will sign up somewhere else where they can receive more free funds. Below we have listed some of the most popular types of welcome or first deposit bonuses.
Matched Deposit Bonus
Deposit match casino promos, as mentioned before, are one of the most common bonus types. It is where a casino matches your initial deposit up to a certain amount. Some online casinos will be really rewarding and match your deposit up to around 200%, whereas some are less rewarding and may only offer you up to 50%. Don’t always go off how rewarding a bonus is because it could mean that if it is really rewarding, the bonus terms are hard to abide by. Deposit bonuses will likely be your favourite type of casino bonus. They are also one of the best bonuses as well, and we recommend claiming them as you can use the funds wherever you like. There are no limitations like with free spin bonuses and other offers.
Cashback Bonuses
This is also considered as a risk free bet. They aren’t the most popular welcome bonus offers, that’s for sure, but they allow you to wager a certain amount and get refunded for it if your wager is unsuccessful. For example, if you wager GBP 50 on a casino game and the wager loses, you can receive this money back and start again, so you aren’t risking anything but have the opportunity to win big. Typically, the cashback offer will be represented in the form of a percentage, so you can calculate just how much you would get back on a losing bet. Although this bonus can be helpful, in comparison to other bonus offers, it really isn’t anything special.
Reload Bonuses
A reload bonus is one that applies to existing UK customers of a casino. It is given to players that have made a deposit in the past. It’s very important for online casinos to offer this to existing players in order to keep them playing there; otherwise, if they feel they aren’t getting any new rewards from their favourite casino very often, they might decide to play somewhere else and take advantage of new customer bonus offers somewhere else. Statistically, the more you deposit as an existing player, the better the reload rewards will be. For example, they might offer a percentage of bonus funds depending on how much you deposit that week. So, the more you deposit, the more bonus funds you receive.
High Roller Bonuses
A high roller bonus is perfect for those who are willing to spend big. If that’s you, then you’ll want to know more about this casino offer for sure. There are different ways in which you can receive this bonus, for example, as a cash gift or a matched deposit bonus. By depositing massive amounts on your first deposit, you will be rewarded with a certain level within the casino’s VIP club. This will allow you to claim a range of rewards and benefits frequently. However, you have to be willing to utilise these latest casino bonuses before they expire, which is why this bonus is really only suitable for frequent big spenders. The more you deposit, the better tier you will be placed in within the loyalty scheme, meaning the more advanced your rewards will be.
Choosing a Good Casino Bonus
There are a few factors that go into making the best online casino offers. The importance of each factor will depend on the type of player, as some have more to play with than others and prefer different game types. But overall, here are some that we would consider being the most important factors in making a good sign up UK casino bonus.
- Bonus amount: Of course, the more rewarding the bonus, the better. Players will often choose casino bonuses that will give them more to play with and offer less risk.
- Bonus type: The type of casino bonus is very important. If you were to compare a cashback bonus to a no deposit bonus, the majority of players would choose a no deposit bonus as it has the possibility of being a lot more rewarding. Customers will tend to prefer casino deals that provide them with more to play with and give them free funds as opposed to just returning part of their losing bets.
- Terms and conditions: Every casino offer comes with its own terms and conditions. Some are more lenient than others, and you want to make sure you’re claiming a bonus that you can actually fulfil the terms and conditions of. For example, if you can’t meet the bonus wagering requirements, then that bonus is irrelevant to you, regardless of how much they are offering in bonus funds.
- Casino site: The casino bonus site itself will also play a factor in whether or not the promotion is good and worth signing up for. If it is a well-known, established casino site that is offering a rewarding casino, then that would be ideal. However, the most rewarding casino bonuses usually come from new casino sites. Luckily, all of the online casinos that we have listed on our site are completely safe and reliable, so you don’t need to worry if they are trustworthy or not.
Bonus Money vs Free Spins: Which Bonus is Best?
There is a big debate in the online casino world as to whether bonus funds are better than free spins or vice versa. In most cases, you will either be a player that prefers slot games or table casino games, in which case you can choose the free bonus spins for slots and bonus funds for other casino games such as blackjack, roulette, live casino games, and more. If you are somewhere in the middle and always find it difficult to choose between cash funds or free spins, then we can help you make that decision. When we talk about cash funds, we mean any UK casino bonus that will reward you with a cash sum. For example, a deposit bonus. Let’s say you have a bonus that will reward you with up to GBP 500 in bonus funds. If you deposit GBP 500, you then have GBP 100 to play with:
- Casino advertises a 100% matched deposit bonus up to GBP 500.
- You deposit GBP 500.
- 500 x 1 = GBP 500 bonus amount.
The bonus cash that you receive will normally have an expiry date and wagering requirements. What that means is that you need to meet the wagering requirements before the expiry date; otherwise, you lose all the remaining bonus cash. An example of wagering requirements might be 40x your bonus. Here is how it will work:
- You can claim GBP 500 in bonuses.
- The wagering requirement is 40x your bonus.
- 500 x 40 = GBP 20,000.
When we are talking about free spins, this offer is very straightforward. However many free spins you get rewarded with, you can use them straight away. In some cases, you will only be able to use them on certain slot casino games. However, most of the time, you can use them wherever you like. Wager the free spins on a slot game and if you land winning lines, you will receive it in bonus cash. For example, let’s say you have 50 free spins and you make GBP 30 from that. You now have GBP 30 in bonus funds. Just like bonus money offers, you still need to meet the terms and conditions, like the wagering requirements. Here is how it can work:
- You receive 50 free spins.
- You make GBP 30 in winnings from these spins.
- The wagering requirement is 10x.
- 30 x 10 = GBP 300 must be wagered.
There are, of course, more terms and conditions for every UK casino bonus, but this is one of the most important ones that is going to affect whether or not you will be able to withdraw any money by the end of it all. Bonus spins are calculated using customer segmentation. What this means is that the casinos will decide who will be awarded what spin bonuses based on certain factors. Firstly, the spins are typically placed on the games that are most popular. This is to get more people playing and enjoying them, giving them the urge to keep playing once they’ve used all the bonus spins. The free spins will also be awarded to those that are most interested according to their CRM. How often a customer plays on the site, how recently they were last online, and their value are all factors that are considered. To conclude our thoughts on it, we would suggest that the bonus cash is better for high roller players because you have the chance to win a lot more and still be able to meet the wagering terms. Whereas if you are a player that doesn’t want to gamble too much, then it will be easier for you to choose the free spins.
Bonus Offer Terms & Conditions
The bane of every casino promotion is the terms and conditions. They can make or break any bonus. Here is everything you need to know about them.
- Wagering requirements: This is the amount of times you need to wager the bonus funds before you can withdraw the remaining balance.
- Casino games selection: Some bonus funds only let you wager the funds on certain casino games.
- Max bet limit: This is the maximum you can bet per wager.
- Winning cap and maximum withdrawal: To stop you from wagering huge amounts and bankrupting the casino, there will be a limit on how much you can win and then withdraw.
- Time-related limit: This is also known as the expiry date. It is the number of days you have to use the bonus funds before they expire and become invalid.
Welcome (Deposit) or No Deposit?
Deposit bonuses are the most popular type of offer, possibly the best casino bonus in our opinion. They are very common, and that’s because they are very attractive for players to redeem. No deposit offers are not as common, but not because they aren’t as popular. It’s because they offer no benefit to online gambling sites, as essentially they are giving out free money without the player having to make a deposit. Both are very appealing offers and great ways to get started at a casino.
Pros & Cons
Here are some of the pros and cons of both bonus types.
