What is a Casino Bonus?

With so many operators and casino sites to choose from, new players, and those looking for a fresh experience, are never short of options when seeking out a new online casino. On the other side of the fence, sites are always on the hunt for new members. To differentiate themselves from the competition and incentivise new players to give them a go, online casinos offer welcome bonuses for first-time deposits, along with ongoing promotions and bonus schemes for regular players.

Why are Casino Bonuses Important?

When it comes to selecting a new casino to play with, it’s tough to find clear-cut reasons to select one casino with a great offering over another. Bonuses can be a worthy deciding factor, particularly as the free funds you stand to enjoy can be a great avenue to try out a new site’s games without having to wager much, if any, of your own cash. If there’s a particular software provider represented in a games library that you’re keen to test out, or just new games in general, doing so with bonus money makes a lot of sense. Not only that, but if you’re entirely new to online gambling, bonuses are a great way to ease yourself in with minimised personal risk. 

Why Do Casinos Offer Bonuses?

You might be wondering why online casinos are so keen to hand out free incentives to players, and the answer ultimately lies in how fierce the competition is. There are countless operators and sites out there that are all vying for your custom in September 2021, and welcome bonuses are a great, player-friendly way for sites to differentiate themselves and win your registration. Once you’re through the door, you can also expect to be offered ongoing bonuses and promotions to keep you invested for reasons beyond great game selections, snappy user interfaces, and top notch customer service.

Types of Online Casino Bonus

There’s an extensive range of bonuses offered by various operators in September 2021, and they each work in their own way. Read on for a breakdown of the various types of casino offers and what you can expect from each one.

Deposit Bonus

A matched deposit welcome bonus sees casinos match your first deposit with additional cash at a specified rate. Matched deposit bonuses are displayed using a percentage to show how much bonus cash you could earn, ranging from 25% up to 500% at some online casinos. There’s often a limit to how much you can earn, so you might see these advertised as something along the lines of ‘200% up to £200’. In this case, the most you can receive in bonus funds is £200. These bonuses are particularly popular because the funds can generally be used across a wide variety of casino games.

So, let’s say you deposit £50 with this deal, netting you a 200% bonus of £100 in bonus cash for a total of £150 to play with. Deposit £100 and you’ll have £300 to play with. Of course, you can deposit more than £100, but you won’t receive any more than the maximum bonus of £200.

Some sites take matched deposit bonuses one step further, offering free spins as part of the same bonus package. This means that players land bonus cash as well as being able to spin the reels on video slots for free. Matched deposit casino bonuses, are currently one of the most popular casino offers in the UK right now.

No Deposit Bonuses

No deposit bonuses are a rare but fantastic treat for any casino player, offering free funds or spins without having to make a deposit to claim them. While these new customer casino offers are a risk-free way to get started with a new operator, the bonus on offer is generally quite small, commonly amounting to around £5 in free cash or up to 50 free spins. Sites also tend to add considerable restrictions to such bonuses in order to protect the casino itself. 

These restrictions can include:

  • Maximum winnings, capping the amount that can be won with your bonus, with anything exceeding the limit being returned to the house.
  • Wagering requirements, stipulating that you must wager a specified amount of your own cash in order to make withdrawals with any winnings from your bonus.
  • Game restrictions, limiting the number of games or game types you can use the bonus for.
  • Time limits, placing an expiry date on your bonus.

Free Spins

Free spins are a fantastic way to get accustomed to slots whilst having the potential to land some winning paylines. Commonly attached to another offer, such as a matched deposit bonus, free spins usually range between 20 and 100 and are often limited to particular games or operators. Starburst and Gonzo’s Quest are common free spins slots, and NetEnt’s also a popular choice for operator-limited spins.

Your free spins are highly likely to be tied to certain restrictions affecting how you can play and what you can withdraw, so it’s always recommended to read the terms and conditions of an individual casino’s offer to make sure you fully understand how it works. You may not be able to withdraw winnings from your free spins, you may be subject to wagering requirements in order to make withdrawals, the offer could be subject to a winnings cap, and the spins themselves may relate to a game besides slots, for example.

Free Cash

Some online casinos set a fixed amount of free bonus cash when you make a qualifying deposit, rather than an amount that’s relative to your first deposit. You might see this advertised as ‘£20 free with your first deposit’. You’ll often be able to use free cash casino bonuses across the games library, although each site will state its restrictions in the bonus’s terms and conditions. These restrictions may be delivered as wagering requirements, game restrictions, a time limit for using the bonus, or a winnings cap on every wager with your bonus funds, to name just a few.

Reload Bonuses

Once you’re playing with a new casino, they’re going to be keen to keep you invested. Reload bonuses are a great avenue for this, meaning you get an additional bonus each time you make another deposit. Alternatively, you may need to deposit a certain amount over a specified period in order to qualify for a reload bonus. The shape these bonuses take varies between sites, with some offering a fixed amount extra when you meet the minimum deposit requirements, while others might offer a percentage of your deposit instead. You might also be gifted some free spins, or perhaps a free bet, in place of or in addition to your reload funds.

Reload bonuses are generally a player-friendly means of topping up your wallet, although they typically come with a few caveats. You may have to reload with a specific payment method in order to claim your bonus, and there will also likely be a minimum deposit you need to make to be eligible. Be sure to check out the terms and conditions of each bonus to make sure you don’t miss out.

Rebate Bonuses

Given that virtually all casino games come down to chance, no one is ever excluded from the possibility of losing money. Rebate bonuses, or cash back bonuses, give players a percentage of their losses back over a certain period of time. The exact percentage and specified period of time will vary between casino sites, but this bonus can help soften the blow if you’ve been on a losing streak.

For example, you may receive a 10% rebate for lost wagers on a site’s sportsbook, netting you a tenth of your wager back. If you wager £10, 10% of which is £1, you’ll get £1 returned to your wallet if you lose. If the rebate percentage is 5%, you’ll get 50p back. 

Unfortunately, rebate bonuses are usually non-withdrawable, but that’s not to say they aren’t a welcome sweetener if luck hasn’t been on your side lately.

VIP Rewards

VIP programmes and loyalty schemes see casino sites reward players with bonuses when they play with higher stakes over a certain time period. While some casino VIP programmes roll out the red carpet and reward players with bonus spins and free cash, others give them access to special perks. You could be endowed with extra funds or spins when your birthday rolls around, a dedicated customer support team to help manage your account, enhanced betting odds, or access to exclusive live casino games and tables, to name a few.

Comp Points

Complimentary points, or ‘comp’ points, work in a similar way to reward points at retailers. While the triggers and values vary between operators, it’s common to see a £10 wager accrue between 1 and 2 comp points at online casinos that offer them, such as 888, Gala, Sky Casino, Betfred, and many more. The points you earn may vary between games, and your points may become more valuable as you rise through a casino’s loyalty tiers. At Sky Casino, for example, first-level loyalty members can exchange 1000 points for £10, while fourth-level members can swap 800 points for £10. In real terms, you need to wager a fair amount in order to withdraw against your comp points, but they’re a welcome bankroll boost nonetheless.

Freeroll Tournaments

Freeroll tournaments—most commonly seen in poker but also available at some sites for blackjack, craps, slots, and more—are competitions that you can enter without a buy-in. Depending on your online casino of choice, freeroll tournaments may be available to everyone, or freeroll entry may be included in your first deposit’s welcome bonus. While buy-ins typically form the bulk of the prize pot in play money tournaments, freeroll tournaments at online sites may offer casino-donated prize money, merchandise prizes, entry to other tournaments, comp points, or non-withdrawable bonus funds for tournament winners.

What Type of Casino Bonus Should I Choose?

Choosing the best casino bonus can be tough, particularly when there are so many great and varied options out there in September 2021. If you’re struggling to settle on a casino offer, or you’re wondering which one is best for you, your experience, and your preferred games, take a look below.

New to Online Casinos

If you’re taking your first steps into the world of online casinos, no deposit bonuses, free spins, and low wagering bonuses will likely appeal most. These bonuses tend to be low value, but they’re also low risk, and you’ll be able to try out the plethora of casino games and betting verticals available without having to wager much, if any, of your own cash.

Experienced with Online Casinos

If you’re already comfortable with online casinos and have a good handle on your favourite games and gambling strategies, you’re probably more likely to be happy to tackle the higher wagering requirements of larger matched deposit bonuses. These bonuses are typically coupled with free spins, which is always a welcome perk. With all that being said, you may still be more inclined towards bonuses with low wagering requirements, in which case you’re best off looking for no deposit and low wagering bonuses, or dedicated spins offers if you’re particularly keen on slots.

Casino Aficionados 

For the high-rollers out there, matched deposit bonuses are likely to be your first choice of bonus. High wagering requirements aren’t necessarily an issue if you play with big sums of cash, and so the bankroll boost of a particularly generous welcome bonus—let’s say in the shape of 100% up to £500 and above—is likely to appeal most to you.

You’ll also want to keep an eye on VIP programmes and their ongoing bonuses, as the upper echelons of tiered VIP systems are more likely to be within your grasp. If your casino of choice offers an invite-only VIP programme, it’s worth researching the conditions for an invite if they’re publicly available. 

Poker Players

If you’re a keen poker player, sites offering freeroll tournaments alongside eligible matched deposit bonuses are likely to be well-suited to your tastes.

Slots Fanatics

Online slots are arguably the most popular online casino game, and there’s never any shortage of free spins options to select from when you’re picking a welcome bonus from the pack. Ongoing promotions are worth researching as well, as many online casinos offer weekly or even daily injection of free spins to play with. Be sure to read the terms and conditions to make sure your free spins are eligible for use on your favourite slots.

Bonus Calculator

Our bonus calculator tool makes it easy to find out the amount you’ll need to wager in order to meet your bonus’s wagering requirements. Enter the deposit value and percentage, the wagering requirements, the contribution percentage of your favourite game, and whether your casino includes your deposit in the calculation.

How to Choose the Best Casino Bonuses

Our quick guide to signing up for the best casino bonuses of September 2021 will have you covered process-wise across the full selection of sites listed on TopRatedCasinos.

  • Read Our Guide on Casino Bonuses

Before you get started, take a look at the quick explainers above on the different bonuses available, and which type of bonus is best suited to particular players.

  • Compare Casinos, Bonuses, and T&Cs

Next, take a look through our rankings and reviews of September 2021’s best online casinos, along with details of the bonuses they offer. The terms and conditions of each bonus is included in our leaderboards, making it easy to compare the best offerings and how their bonuses will work in practice.

  • Sign Up and Opt-In

Once you’ve settled on an operator, click through to their site and sign up with your details. Be sure to opt-in to the casino bonus offer, and keep an eye on the terms and conditions for eligibility.

  • Make Your First Deposit

Once you’re signed up and have opted in for the welcome bonus, head over to the cashier page to make your first deposit to your new account. Make sure that your payment method is eligible for the offer, and ensure you fulfil any minimum deposit requirements too.

Other Factors to Consider

Whilst selecting the best bonus for you, bear each of these factors in mind as they can all considerably impact the true value of your choice.

Cash Out Limits 

Cash out limits, or winnings caps, place a hard limit on the amount you can win when wagering with bonus funds or spins. For example, your 100% up to £25 matched deposit welcome bonus may be wager free, but it could come with a winnings cap of £100. Therefore, anything you win over £100 with your bonus funds will be unavailable for withdrawal, and will instead be returned to the house. As such, it’s worth keeping your winnings cap in mind as you play through your bonus. Even if you were lucky enough to win big on the jackpot, you would only get to keep a portion of the winnings if a cap is in place. 

Typically, low wagering and wager-free bonuses will have lower winnings caps than bonuses tied to wagering requirements, and those with tougher requirements might have no winnings cap applied at all.

For example, two very similar bonuses could end up looking like this:

          100% up to £25, no wagering, with a winnings cap of £100

          100% up to £25, 35x wagering, with no winnings cap

There is no hard and fast rule for how online casinos set winnings caps on particular bonuses, so be sure to check out the terms and conditions before settling on your bonus of choice.

Wagering Requirements

Wagering requirements are perhaps the most significant restriction you’ll come across with bonuses. Simply put, wagering requirements are used to calculate the amount you must wager before being able to withdraw against your bonus, and they’re in place to make it as safe for the casino to deliver bonus funds as is fair and reasonable.

For example, let’s say you have claimed a 100% up to £200 welcome bonus, netting a cool £200 in free funds, but the wagering requirements are 35x.

          £200 (bonus) x 35 (wagering requirements) = £7,000 (total that must be played)

Some online casinos include your initial deposit in this equation:

          [£200 (deposit) + £200 (bonus)] x 35 = £14,000

As you can see, it’s well worth paying attention to which method your casino of choice uses, as you could be faced with considerably steeper wagering requirements before being able to make withdrawals if they include your deposit in the calculation.

35x is a very common wagering requirement, with lower numbers generally considered ‘low wagering’ and higher figures constituting ‘high wagering’. The greater the value of the bonus, the likelier it is that they will have high wagering requirements, so be ready to wager a substantial amount for any matched deposit exceeding 100%.

Free spins are likely to come with wagering requirements attached too, although they work slightly differently. Let’s say you’ve taken your 25 free spins and won £100, but your spins were attached to a 35x wagering requirement. Your winnings, in place of bonus funds, are then the basis for your wagering requirements:

          £100 x 35 = £3,500

Game Weighting Restrictions

Completing bonus wagering requirements isn’t as straightforward as playing your favourite casino games a handful of times, as there are usually restrictions on which games contribute to wagering requirements. At many casino sites, wagers on most slot games contribute 100%, whilst bets on table games can count for as little as 10%. Some online casinos exclude certain games altogether from the wagering, so this is definitely something to read up on in the small print.

So, let’s say you’re working towards £7,000 in wagering requirements. If you’ve wagered £200 on slots weighted at 100%, the full £200 will be counted towards your journey to £7,000. Alternatively, you may have wagered £200 on blackjack weighted at 10%, meaning only £20 is counted towards your wagering requirements. If you’re dedicated to clearing your wagering requirements as quickly as possible, bear weighting in mind before picking a game to do it with.

Time Limits

Not only will you need to complete wagering requirements, but you’ll likely also need to do this within a specified time frame. Failure to complete requirements within this period means that bonus funds will expire, often along with any associated winnings. Some sites are generous and allow in excess of 30 days to complete the playthrough requirements for casino offers, but others give players just a handful of days.

Games Restrictions

Restrictions don’t simply apply to game weighting — some casinos also set rules as to which games players can use their bonus funds on. Obviously, free spins are restricted to slot games, but you might find that progressive jackpot games aren’t included in the offer. Likewise, you may only be able to use your free cash on certain versions of table games. Of course, you can still play other games, but you won’t be able to do so with your bonus funds.

With that in mind, game restrictions are definitely something to consider as you select your first deposit bonus. If you’re set on playing particular games, it would be a shame to find out too late that your bonus doesn’t cover them, so be sure to check the terms and conditions before signing up.

Payment Method Restrictions

Keep an eye out —  deposits made with certain payment methods may not be eligible to claim a casino bonus. It goes without saying that you’ll need to meet the minimum deposit requirements to claim, but how you deposit could also have a bearing on your eligibility. It’s often e-wallets like Neteller and Skrill that are excluded from casino bonuses, but some sites have bonuses exclusive to PayPal or debit card deposits, or even bank transfers through services such as Trustly. As with all other bonus restrictions, these details will be covered in the terms and conditions.

Casino Offers and Promotions

With so many top online casinos in the UK to choose from in September 2021, you can expect brand new casino promotions daily. This is great news for anyone looking to enhance their online casino gameplay with the latest giveaways, competitions, prize draws and free spins no deposit offers. Of course, making sure you don’t let any great deals slip between the cracks is a tall order. That’s where we come in: we’ve got them all in one place. You’ll find any casino promotion worth your time right here, as and when they become available.

We’ve also got all the need-to-know information on promotion eligibility, wagering requirements and, most importantly, how to claim your bonuses. Keep your eyes peeled to make sure you snap up September 2021’s best UK casino offers before they expire.

Online casino operators are understandably hot on abuses of their welcome bonuses, and withdrawals against bonuses under suspicious circumstances are likely to be blocked or, at the very least, investigated. Red flags can include, to name a few, multiple sign-ups from the same IP address, a pattern of specific deposits being made to claim the same bonus, immediate withdrawals once the bonus’s requirements have been cleared, and patterns of extended play on the same game across multiple accounts.

Your Guide to Casino Promotions

Here’s a breakdown of everything you need to know about online casino promotions and how they work in September 2021.

New Casino Game Promotions

What better way to celebrate the release of a new game than a brand new casino offer? Free spins and leaderboard promotions are a common way for casinos to generate some buzz around the latest titles, and they’re usually targeted at online slot players. If you’re a fan of spinning reels, you might be able to snag extra spins to use on some of the latest additions to your favourite casino’s game collection.

Casino Giveaways

While most promotions offer rewards such as online casino bonuses and free spins, giveaways open the door to some serious VIP treatment. These can range from all-inclusive luxury getaways and huge cash giveaways to tickets for some of the biggest sporting events of the year. Giveaways are easily accessible for most players too – you’ll usually only need to place wagers on a predetermined selection of games to be in with a chance of winning a prize.

Casino Competitions

Some giveaways see winners drawn at random, while others function in a more competitive fashion, featuring a leaderboard. This kind of promotion is best suited to high rollers, as your place on the leaderboard is usually determined by the total amount staked. These promotions usually end with more than one winner too, with cash prizes, bonuses and free spins often shared amongst hundreds of players.

Frequent Rewards

New slots promotions and giveaways only come around every so often. Keeping your eyes on our casino offers feed is one way to make sure you never miss out on the biggest deals, but there are some casinos that award players with bonus offers as part of their regular schedule. Pick out the right casino and you could claim daily free spins, reload bonuses and even weekly cashback offers.

Casino Bonus Payout Percentage

Bonus payout percentages can be the most eye-catching part of our casino leaderboards, but it’s worth noting that bigger is not necessarily better for every player. Because wagering requirements come into play for most lucrative welcome bonuses, the biggest payout percentages often have the most sizeable requirements to hit before making withdrawals. 100% is by far the most common three-figure payout percentage you’ll come across, but operators occasionally raise the stakes, and consequently the wagering requirements, considerably. Here’s a quick look at how payout percentages translate into wagering requirements at 50x wagering:

Matched % — (Deposit + Bonus) x wagering = Total wagering requirements

          100% — (£50 + £50) x 50 = £5,000 

          200% — (£50 + £100) x 50 = £7,500 

          300% — (£50 + £150) x 50 = £10,000

          400% — (£50 + £200) x 50 = £12,500

          500% — (£50 + £250) x 50 = £15,000

As you can see, the greater the percentage the more considerable the wagering requirements, potentially necessitating a huge amount of cumulative deposits if you’re hoping to make withdrawals against your bonus. For high-rollers, or those who purely play for fun, the prospect of £7,500+ wagering requirements may not be too off-putting. For everyone else, it’s something to keep in mind when you’re selecting your bonus.

Frequently Asked Questions

  • This varies between casinos. While some give players the freedom to use their bonus funds as they wish, others limit players to standard versions of slots and table games. Be sure to familiarise yourself with the terms and conditions before you claim a bonus, especially if you’re looking to play live dealer casino games.

  • Not always. In most cases, you’ll simply need to tick a box to opt in to the casino welcome bonus, which will be credited to your account once you’ve made the qualifying deposit. If you do need a welcome bonus promo code, the casino site will make this clear.

  • This depends on whether you have a fully-withdrawable bonus, or a sticky bonus. A sticky bonus means you’ll be able to withdraw the winnings you’ve earned with your bonus, but not the bonus itself. For example, if your total bankroll is £100 after using your £20 bonus, you’ll get to withdraw £80 in total once you satisfy the terms and conditions.

  • For sure. Most online casinos allow players to claim a bonus no matter which device they’re using. As well as mobile-friendly websites, the UK’s best casino sites even have native mobile apps for Android and iPhone, which make it easy to claim the latest casino bonuses like free spins, matched deposits and no deposit bonuses on your mobile device. If you download a casino app, you can enable push notifications so that you’re always alerted to the latest bonuses and promotions, even when you’re out and about.

  • Not necessarily. Some casino sites split deposit funds over the first few deposits, rather than offering the whole sum upon the initial payment. In some cases, the initial deposit amount will be just a portion of the advertised sum, which is why it’s always worth understanding the terms and conditions before you sign up.

  • Unfortunately not. The majority of casino games are dependant on chance, which means there’s very little you can do to increase your chances of making a profit- least of all claiming a casino bonus. These bonus funds can boost your existing bankroll and keep you playing for a little longer, but they don’t make you any more likely to win. The best way to increase your chances of winning at online casino games is to understand the ins and outs of gameplay, using free games to practise before you move onto real money casino games.
