Casino Bonus Basics

Casinos award bonus funds and free spins to attract new players and keep existing players coming back. It’s a rare win-win situation in online gambling, as it also gives players more shots at winning online casino games by giving their bankroll a boost.

Of course, you could just as easily lose all your bonus wagers, but even if you don’t make a profit, there are still advantages of claiming a casino bonus. At the very least, casino bonuses give you a chance to get familiar with the games library, as well as the look and feel of your new casino site, without risking any real money funds.

What kind of bonuses are available at online casinos?

There are a wide variety of bonuses available online, so it pays to do your research and figure out which type suits your playing style and bankroll best. We’re here to make this an easy task for you, so let us take you through the basics of each bonus type and highlight the advantages and drawbacks of claiming them.

Matched Deposit Bonuses

The most common type of welcome bonus sees casinos reward newly registered players for making an initial deposit, and sometimes for their first few deposits following this. This bonus does exactly what it says on the tin; place a deposit and the casino will match a percentage of it in bonus funds, usually between 50 and 200%.

Let’s take a look at an example of a typical matched deposit bonus:`

100% Matched Deposit Bonus up to £100

This simply means that any deposit you make, up to £100, will be matched pound for pound by the casino in bonus funds. While you’re welcome to deposit more than £100, don’t expect to receive more than £100 in bonus funds as a result.

While you’ll find that the biggest bonuses on offer are usually matched deposit deals, this is offset by the stringent wagering requirements they almost always come attached with.

Reload Bonuses

Bonuses for new players are by far the most rewarding, so it’s no surprise that online casino players often go ‘bonus hunting’ – going from one casino to another taking advantage of new customer offers. But, if you like your new casino enough to stick around, you’ll be glad to know that the bonuses don’t stop once your welcome bonus has expired. Reload bonuses give returning players incentive to return and make deposits. Somewhat similar to matched deposit bonuses, a typical reload bonus sees casinos award players with extra funds for depositing a certain amount.

No Deposit Bonuses

A no deposit bonus is the best way to enjoy what is essentially a free trial period at your chosen casino, with no strings attached. All you need to do to claim your free casino funds is register an account. Once your bonus has expired, you’ll probably know whether it’s the right casino for you, or whether you should continue your search.

Of course, most no deposit deals come with wagering requirements, so you’ll have to meet

these before you can withdraw any bonus winnings you may earn. In comparison to other bonuses, there’s less pressure to do so; with no initial deposit is required, it’s impossible to lose real money stakes here. This makes a no deposit bonus a great option for players on a tight budget. The only drawback is that the value of the bonus is often quite modest. You’ll usually only be given £5 to £10 to play with, or the equivalent in free spins.

No Wagering Bonuses

There are a growing number of casinos offering player-friendly wagering requirements that make withdrawing bonus winnings a more realistic prospect for casino players. However, if you fancy getting your hands on your bonus earnings right away, then a no wagering bonus is definitely the way to go. Much like no deposit deals, you’ll usually only receive a small amount of free spins, or a bankroll boost up to £10. Where this offer differs, however, is that most casinos will require you to make a deposit to claim your bonus.

Free Spins Bonuses

Just about every online casino offers free spins in some fashion – from extra spins as part of a new customer matched deposit bonus to promotional free spins celebrating the release of a new slot game. It’s a great, simple way for new and existing players to enjoy spinning the reels for free. The number of free spins offered varies from casino to casino, and largely depends on whether the free spins are awarded on their own or as part of a bonus package. You can expect to receive somewhere between 20 to 100 free spins, but you’ll usually have to satisfy a wagering requirements before you can withdraw any bonus winnings.

Cashback Bonuses

As its name suggests, cashback bonuses are awarded as a consolation prize after a period of gameplay that sees you lose a certain amount of funds lost to the casino. These bonuses are usually a small percentage of what you’ve wagered in this time, and you’ll usually be limited to a certain amount.

Let’s take a look at an example of a typical cashback bonus:

10% cashback up to £100

In this case, the maximum amount of cashback you’ll be able to claim is £10. This limit isn’t the only one placed on cashback bonuses; casinos will almost always set an expiry date for the bonus, and in some cases the bonus will come with wagering requirements.

How to choose the best casino bonus:

Now that you know what to expect from each type of bonus offer, you probably have an idea of which one suits you best. However, the search doesn’t end here. Once you’ve picked out your favourite type of casino bonus, you’ll find that there are tons of casinos offering them. So, let us take you through a few top tips for finding the best casino bonus for you.

Wagering Requirements

Some of the biggest bonuses come in the form of matched deposits, but it’s important to remember that the bonus sum shouldn’t be the only factor you consider when picking a bonus. The best bonus is one that gives you the best shot at cashing out your bonus winnings. This will mean steering clear of bonuses with wagering requirements that don’t give you a realistic shot at grabbing your bonus winnings.

Game Weightings

Before you start playing through any bonus winnings, it’s well worth taking a look at the game weightings found in the terms and conditions. Money wagered on certain games don’t contribute to meeting wagering requirements at all, while others may have a reduced contribution weighting. For example, 100% of the money wagered on slots will contribute to satisfying the wagering requirements at most casinos, compared to stakes on table games, where the game weighting is often as low as 10%, or excluded altogether.

Maximum Payouts

Most online gambling sites use winning caps to limit how much cash you can win from your bonus funds. If you’re restricted to a 5x winning cap, for example, you can only win five times the value of the bonus you claimed. We’d recommending keeping an eye out for this information in the terms and conditions – it’s just another way to narrow down your search for the best bonus.

We’ve given you our Genius casino bonus walkthrough, so all that’s left for you to do is decide whether or not you want to claim your very own welcome bonus today.

FAQ

Can I meet my wagering requirements by placing low-risk bets, such as red and black on roulette?

This depends on the terms and conditions of your chosen bonus. Most casinos have rules in place that prevent bonus wagering on low-risk bets such as these. A common example is the game weighting tables. You’ll often find that only a small percentage of your stakes on table games contribute to your wagering requirement. In some cases, your table games stakes won’t contribute at all. This encourages players to play through their bonus winnings on slot games, which don’t feature any low risk betting options like the even money bets featured in roulette.

Are there any exclusive bonuses for high rollers and VIP players?

Most casinos don’t offer bonuses for high rollers and VIP players. Instead, there are loyalty programmes that are open to all players. These programmes reward players for playing real money games; the more you play, the more you earn. Naturally, a high roller will earn more rewards, so if you’re playing with a big bankroll, it’s well worth keeping an eye out for a casino with a rewarding loyalty scheme.

Can I use my bonus funds all at once?

If your casino hasn’t set limits on the amount of bonus funds you can use at once, and your bonus stake doesn’t exceed the maximum bet on your chosen game, then you can use your bonus funds all at once. However, in the few instances that there are no limits on your maximum bonus bets, your total bonus balance will be quite modest anyway.

Do I have to claim a casino bonus?

No. If you don’t fancy playing through your bonus to satisfy wagering requirements, or being limited by any of the other terms and conditions that are often attached to casino bonuses, you can simply make your first deposit and start playing real money games right away.

Can I withdraw my funds without meeting wagering requirements?

Yes, but only if you’ve claimed a no wagering bonus. If you choose a bonus with wagering requirements, your bonus winnings won’t appear in your main balance, which means you won’t be able to request a withdrawal.

Can I claim a casino bonus on my mobile?

Yes. The UK’s best casinos offer mobile-friendly sites and native apps that allow players to sign up, deposit and claim bonuses on the go.
