Best Casino Bonuses for Slot Players in 2022

If you’ve ever played slots for real money, then you may have come to expect casino bonuses that allow you to play your favourite slots with some extra cash. Casino bonuses on slot games can be anything from free spins to bonus money awarded on different occasions. In this article, we’ll introduce you to the best casino bonuses for slot players who would love to benefit regularly from such offers, and explain how Slot Tracker can help you make more profit from casino bonuses.

What is a Casino Bonus?

A casino bonus is an offer that is awarded by an online casino operator to its new or existing customers. There are different types of casino bonuses that can be used on slots, and players today will get the opportunity to claim multiple bonuses from different slot sites.

How do casino bonuses work?  

Every casino bonus comes with its own terms and conditions that may restrict its use or the amount of winnings that players can get. In general, casino bonuses come with a minimum deposit requirement, which is the deposit that a player needs to make in order to claim the bonus. However, there are also no deposit bonuses available at some slot sites, which are awarded once a new player creates an account.

Most casino bonuses come with wagering requirements, as well as other limitations, which we’ll explain below in order to help you identify the best slot bonuses.

What to look for to use a casino bonus

There are several things to consider before you claim a casino bonus. First of all, if you love slots, then you’ve got to make sure that your bonus can be used on slot games. Secondly, you’ve got to assess how likely it is to make a profit from this bonus should you get lucky. We’ll explain this in more detail in the next sections.

What are wagering requirements?

Wagering requirements refer to the number of times that you will need to wager a casino bonus once this is claimed. When a bonus is tied to wagering requirements, you need to play through the amount of that bonus for the specified number of times before you can withdraw your winnings. In the meantime, all your winnings will be stored in your account’s Bonus Balance. 

Of course, the higher the wagering requirement, the more likely it will be for you to lose your winnings in the process, since all slots come with a house-edge. This is why Slot Tracker recommends going for a casino bonus with low wagering requirements, or even with no wagering at all (as is the case with some free spins bonuses).

What are Game Restrictions?

All casino bonuses will have game restrictions, which means that certain games at the casino will be excluded from the bonus. Free spins bonuses, for example, can typically be used on just one slot, or a few selected slots. 

If you’re fussy about which slot you’d like to play with a bonus, then you should take note of these restrictions. The good news is that deposit match bonuses at the best slot sites can normally be used on a great selection of online slots.

Minimum / maximum stake

Operators will not allow you to bet as much as you like while wagering a casino bonus. This is why they specify the maximum bonus bet in their terms and conditions (which is normally equivalent to around €5). Free spins bonuses, on the other hand, will have a spin value, which is typically on the lower side of the spectrum (between €0.10 and €0.20 per spin). Of course, this will give you an indication of the amount you can expect to win from a bonus!

Maximum win limits

Some bonuses impose a limit on the amount you can win from a bonus. It is not uncommon for free spins bonuses to impose such a limit (for example, no matter how much you actually win, you may be allowed to withdraw only a maximum of €200 in winnings at some casinos). However, the best slot sites don’t usually impose such a limit, especially when it comes to their welcome bonuses.

Bonus Validity

All bonuses will come with an ‘expiry date’, which you’ve got to take note of so as not to lose your bonus or your winnings! The best slot sites offer bonuses with a reasonable validity, giving you a month or two to wager your bonus. That said, free spins typically come with a shorter validity, which can be as little as 24 hours. This means that you’ve got to use your spins and wager your winnings within this period.

Deposit Method Restrictions

Another thing to keep in mind if you intend to claim casino bonuses are the deposit method restrictions. Some deposit methods are excluded from bonuses, which means that you can’t claim a bonus if you deposit using these methods. Two such methods are the e-wallets Skrill and Neteller, since these have their own rewards systems.

Market Restrictions

Last but not least, some operators will exclude certain countries from their bonuses, so it’s important for you to play with a slot site that rewards players from your country. Restricted countries are normally listed in the bonus terms and conditions, although the currency with which a bonus is marketed should give you a good indication of whether players from your country qualify or not!

How to play with a Casino Bonus 

Once you claim a casino bonus, you’d need to use it wisely, and this is exactly what Slot Tracker helps you to do! By showing you which slots are likely to pay out the most and which operators have the best RTP rates, you’ll get a better idea of how and where to play your bonus.

How to claim bonuses from slot sites 

There are several ways of getting a bonus from casino operators. The biggest bonuses are to be had on first deposit, so it’s worth joining a few new slot sites and claiming multiple welcome bonuses by making the minimum deposit required. Once you join a slot site, you should also sign up for its newsletter in order to get to know about reload bonuses or spins, or check its Offers page on a weekly basis for the latest bonuses.

How to wager your casino bonus 

You should try to wager your casino bonus on the best paying slots if this is possible. Slots with a high RTP and high payout potential will give you a better chance of winning while wagering your bonus. 

Slot Tracker provides actual RTP rates of different online slots, to help you identify the best payout slot games. Another feature, the ‘wager rating’, gives you an indication of how easy or difficult it is to wager a bonus on each specific slot. You will see a wager meter, ranging from Very Bad to Excellent, which will help you decide whether it’s worth wagering your bonus on that slot.

Bonus funds vs. real money funds

As we’ve already said, once you claim a bonus, you’ll see the amount of your bonus and any winnings accumulated from it in your Bonus Balance. Similarly, if you get free spins, the winnings from your spins will be visible in your Bonus Balance first. In order to convert these winnings to cash and make them withdrawable, you need to complete wagering requirements. 

That said, there are some free spins offers that come with no wagering requirements. Winnings from these spins will go directly to your cash balance, for you to withdraw or use as you please!

How to withdraw a casino bonus

Once you complete the wagering requirements, you should be allowed to withdraw your casino bonus by making a withdrawal request. The casino will ask you to choose your preferred withdrawal method for this. That said, most casinos have a minimum withdrawal limit (which typically ranges between €10 and €40), and may not allow you to withdraw lower amounts. 

How to make money from casino bonuses 

If you’d like to know how to profit from a casino bonus, you’ve got to claim a good bonus and use it on the best paying games. We’ve got the following tips for you:

  • Claim a bonus with low wagering requirements or no wagering
  • Use your bonus on a high RTP slots with a good hit rate
  • Try and go for a slot with a great bonus game that is not too difficult to trigger (since the biggest wins are normally to be had from the bonus game)
  • Use your bonus on a slot game with a good Wager Rating 
  • Bet lower amounts in order to get more spins from a bonus

Slot Tracker can help you with most of the above points, as it shows you how difficult it is to trigger the bonus round in each slot, and gives you other metrics, such as hit rate and average bonus win, to help you find the best slots to play.

Slot Bonuses

Casino bonuses that are usable on slots are the norm at online casinos, which is a great thing for slot players. There are different types of slot bonuses on offer, and in this section we’ll be taking a look at the most common ones to let you know what to expect.

Welcome Bonus (sign-up bonus)  

The casino welcome bonus, or sign up bonus, is the most common bonus type, as it is offered by most casinos and slot sites. 

What is a casino welcome bonus?

Casino welcome bonuses may consist of any type of offer that is awarded to new players who register with a casino. It can be a no deposit bonus, a deposit match offer, a free spins offer, or a mix of both. 

How do Casino Welcome Bonuses work?

Welcome bonuses work in various ways, as each operator will impose its own terms and conditions. The only common thing between them is that they are all awarded to new players. The best casino welcome bonuses will consist of ‘welcome packages’ which reward you on your first few deposits, and not just on your first one. These may consist of a combination of bonus money and free spins.

How to claim a Casino Sign Up Bonus

To claim a slots welcome bonus, you need to create an account with the slot site. Most casinos will require you to opt-in for the bonus on sign up. 

Sometimes, a no deposit bonus will be awarded to you automatically once you verify your account, but for most welcome bonuses, you need to make the minimum deposit required using a bonus-eligible payment option. The amount of your bonus should then be visible in your Bonus Balance. Free spins as part of the welcome bonus may become available once you launch the eligible games, or you may need to claim them from a particular section in your casino account.

No Deposit Bonus

No deposit bonuses are everyone’s favourites, although they’re not as easy to come by these days. And yet, some of the best slot sites still offer them, giving you the chance to play free slots and win real money!

What is a No Deposit Bonus?

As the name implies, a no deposit bonus can be any casino bonus that is awarded by the operator without requiring a deposit first, subject to certain conditions. A casino bonus no deposit keep what you win offer has the added benefit of being free of wagering requirements, although this type of no deposit bonus is quite rare to come by.

How do No Deposit Bonuses work?

Most no deposit bonuses are awarded when a player first registers and verifies his or her account with a casino. These serve as a welcome treat, as well as an incentive for players to try out games at the casino for real money. 

The majority of no deposit bonuses consist of no deposit free spins on a specific slot, or a selection of games. Each of these spins will have a real-money value, enabling you to win real cash if you get lucky as you spin. Of course, most no deposit bonuses will also come with a wagering requirement, and sometimes you would need to make a deposit in order to be able to complete the wagering.

How to claim a No Deposit Bonus

To claim a no deposit welcome bonus, all you need to do is successfully create an account with a casino or slot site. The casino will not award you this bonus if you try to create another account from the same household or IP address. Once you register and verify your account successfully, you will be informed about where to claim your no deposit bonus by the casino.

Free spins Bonuses 

A slot lover’s treat, free spins bonuses are a great opportunity to extend your playing time on slots! Luckily, free spins are easy to come across today, and the best slot sites offer them to both new and existing players.

What is a free spins bonus?

Free spins, also known as bonus spins or extra spins, will consist of a set of real-money spins for use on one or more slots at a particular casino. Conditions for free spins bonuses will vary depending on the offer and the platform you get them from. Sometimes you will get as little as 10 spins, whereas some casinos can award hundreds of free spins, especially as part of their welcome package.

How do free spins bonuses work?

Each free spin will have a real-money value, which means that you will be playing the slot by staking that amount on each spin. Normally, spins given away for free will have a value that corresponds to the minimum bet on a slot game (between €0.10 and €0.25 each). You can then win the amount of that value multiplied by the winning combinations that you hit while spinning (for example, a spin of €0.20 that hits a combination which pays 1,000x your stake will pay out €200). 

Like all casino bonuses, most free spins bonuses will come with wagering requirements. In this case, the wagering will apply to the amount of your winnings from the spins. For example, if you get free spins with a wagering requirement of 20x, and you win €100 from your spins, you would have to wager €2000 before you can withdraw any remaining balance.

How to claim a free spins bonus

Free spins bonuses can be claimed either as part of a no deposit bonus, a casino welcome bonus, regular or special offers for existing players running at specific days or times during the week, or on specific occasions. There are plenty of opportunities around, and all you need to do to claim your spins is deposit the minimum required during the promotional period. 

Remember that free spins bonuses tend to have a short validity, so make sure that you use and wager your spins within the specified timeframe!

Reload / Deposit bonus 

Reload bonuses are what keep existing players happy at a slot site, and can be a great way for players to boost their balance on a regular basis. 

What is a reload / deposit bonus

A reload bonus, or deposit bonus, is an offer given to existing players who have already claimed their welcome bonus. The best slot sites tend to offer reload bonuses on a weekly or daily basis. Most reload bonuses will require a deposit and will come with wagering requirements and game restrictions.

How do reload bonuses work?

Reload bonuses can take the form of deposit match bonuses (for example a 50% bonus on Monday deposits), or free spins (for instance, a set of free spins if you deposit on certain days of the week). These bonuses tend to be valid for a short time every week (for example during ‘Happy Hour’), although they can also be awarded on special occasions throughout the year, such as during the Christmas period.

How to claim a reload / deposit bonus

Players can get to know about reload bonuses by visiting the Promotions page of a casino, or by subscribing to a casino’s newsletter. To claim them, you normally have to make the minimum deposit during the promotional period indicated in the offer terms and conditions. 

No Wagering Bonuses

Casino bonuses with no wagering requirements are highly sought after these days, because of the obvious benefit they provide: with these bonuses, you get to keep your winnings, although there may still be some restrictions in place.

What is a no wagering bonus?

A no wagering bonus could be a set of free spins or a cash bonus that comes with no wagering requirements. This will normally consist of a small bonus, which is awarded either on deposit or as a reload bonus.

How do no wagering bonuses work?

After you play your no wagering bonus, you should be able to withdraw your winnings from it immediately, as you will see the amount of winnings generated in your cash bonus. However, sometimes operators impose a maximum cap on winnings from a no wagering bonus, to avoid having someone walk away with huge amounts of cash without having wagered anything.

How to claim a no wagering bonus on slots?

To claim a casino bonus with no wagering requirements, you need to find a slot site that offers one. This can be quite difficult, as most operators impose wagering requirements these days. However, there are a couple of casinos that offer them, both as part of their welcome bonus as well as part of their rewards or VIP programme.

Cashback Bonuses 

Cashback is something most of us are familiar with, and this kind of offer is getting increasingly common across online slot sites as well. Although more commonly awarded on live casino games than on slots, a good cashback bonus can give you a nice boost when you most need it

What is a Cashback Bonus?

A cashback bonus involves getting a certain amount of cash back from your losses at a casino, or getting some additional bonus money based on the amounts of your deposits. Some casinos will also award cashback as part of their rewards or loyalty programme, whereas others may award it to existing players on certain days of the week.

How do Cashback Bonuses work?

Cashback bonuses at online casinos can work in two ways: the least favourable of them would involve a percentage of your losses given back to you in cash (for example 15% of your losses will be refined back to your account). Our favourite cashback bonuses involve those that allow you to get cash back on the total of your deposits, regardless of whether you win or lose. 

How to claim a Casino Cashback Bonus

A cashback bonus is more commonly offered to existing players rather than to new depositors at a casino. To claim a cashback bonus, you need to find a slot site that offers one, and check out the offer terms. More often than not, the cashback bonus will be awarded only if you play certain types of games.

The best way to get cashback in the long term is to join a casino VIP programme, as most loyalty programmes will involve cashback, especially for players at the higher tiers.

Mobile casino bonuses 

As mobile slots are becoming the norm these days, it comes as no surprise that slot bonuses are usually available on mobile devices as well. You can claim bonuses on your mobile device in much the same way that you would on desktop, either via the casino app or using your mobile browser.

What is a Mobile casino bonus?

A mobile casino bonus can be a special bonus offered to players who use the casino’s mobile app as opposed to the desktop version. 

However, these days, most mobile casino bonuses are the same ones available also on desktop. You can claim a welcome bonus, a no deposit bonus, a reload bonus or free spins by logging in to the casino via the mobile app or your mobile browser.

How do Mobile casino bonuses work?

Any bonus that you claim from a slot site should be visible on your account, whether you log in to the site via your desktop or mobile. Therefore, mobile casino bonuses work in exactly the same way as other slot bonuses, except for those special mobile bonuses that are offered exclusively to app users (however, these mobile casino bonuses are not so common anymore).


Online casino bonuses can be a great way to play free slots for a chance to win real money. The most important thing for players is to identify the best slot bonuses that will give them the best chance of making a profit from them while playing their favourite slots. Remember, Slot Tracker can be of great help with this, as the tool will show you which slots it’s best to wager your bonus on, and which slot sites pay out the best. You can sign up for Slot Tracker on this page, to start gambling smarter and winning more on slots today!


Why can’t I withdraw my casino bonus?

In order to be able to withdraw your casino bonus, you first need to complete any wagering requirements. This means that you have to wager the amount of your bonus for the amount of times specified by the casino, before the winnings can be released to your cash balance. 

Online casino no deposit bonus – how does it work?

A no deposit casino bonus is any kind of bonus that is awarded to players without requiring a deposit. Most no deposit bonuses are awarded on registration with a new casino, and come in the form of no deposit free spins on slots.

How to make money from slot bonuses?

To make money from a casino or slot bonus, you need to claim a good bonus with decent wagering requirements and terms. Then, it is best to use your bonus on high paying games which give you the best chances of winning a fair amount of cash.

What is the best casino bonus?

The best casino bonuses are those that come with no wagering requirements or with low wagering, enabling you to keep as much of your winnings from the bonus as possible. We love casino bonuses that can be used on a variety of slots, and that do not impose any restrictions on the amount you can win.
