Choosing the Best Slots Bonuses

On our Slots Bonuses page, and in every other page of you have the opportunity to see the most important terms on every Casino Bonus immediately. This makes it easier for you to choose the appropriate bonus. Because you should always check T&Cs into account when making a decision for or against slots bonuses.

Simply move the mouse pointer over the underlined “T&Cs Apply”. Or tap it with your finger when visiting from your smartphone or tablet. You will then see a small window in which we have listed the most important information about the bonus conditions for you.

Many casinos have restrictions on the countries whose players qualify for a bonus. So only players from certain countries can access the bonus. Be sure to briefly review this information when viewing a bonus promotion in a new casino.

All of the casino bonuses presented have their very own advantages. So how do you choose the bonus that suits you best? There are offers for every budget and for every type of player. You just have to know what is important to you, then you can secure something suitable.

Deposit amount

First of all, you usually have to deposit a minimum amount to claim a casino bonus. You do not get the bonus for a deposit of 1 or 2 euros, but only from higher amounts. For most providers, the minimum amount is 10 to 20 euros. This restriction also makes sense, since smaller deposits would not be worthwhile for either the player or the casino.

Some casino bonuses are tied to certain deposit amounts. You usually get welcome bonuses from a deposit of €20. Casino bonuses, which you get from regular offers, often require a minimum deposit amount before you can use the bonus. So think about whether the deposit amount is worth the bonus to you.

Payment methods

There are offers where you can get a casino bonus if you use certain payment methods. There is nothing wrong with that, unless you are using a certain payment method exclusively for gambling.

It may well be that you do not want to open a new account with a payment provider or that you do not want to link your personal data to your gambling account. On the other hand, bonuses are also a great way to try out a deposit and withdrawal method that you were already interested in. And maybe you can even get fastest payouts. Note that if you use e-wallets like Skrill or Neteller, you can often be excluded from using a casino bonus.


Some casino bonuses work better than others for certain types of games. Depending on which casino slots games you prefer, you should of course also choose your bonus. Starting credits and all forms of real money bonuses are suitable if you want to use your bonus without restrictions. You can use the money on online slots as well as on table games. Live casino bonuses are often a separate promotion.

Free spins are of course particularly popular with slot lovers, they are even more worthwhile if an online casino gives you the wagering requirements. Many casinos also lure with free spins on the slot machines as a casino bonus. Often these are offered on the one hand without a deposit and thus represent a top-class casino bonus.

However, it is usually more worthwhile if you make at least the minimum deposit. Because many providers put a decent amount of free spins on top when making a deposit. So, with a deposit of just ten euros you can benefit from several 100 spins on the slots. Then there is the further subsidy of the casino bonus. And this way you often get € 20 and free games for a meagre deposit of just €10.

If you compare this with the non-existent casino bonus at land-based casinos or the classic lottery ticket, you can see the advantages of casino bonus on the net. In detail, of course, what kind of bonus conditions apply. In most cases, however, it is worth taking the additional money from the casino bonus with you.

Of course, there are also bad offers, which usually only become apparent when you read the small print. For this reason, it is always a good idea to look at the bonus terms. Also check out our wagering guide if you need help finding. Depending on the gambling authority, there are some rules when it comes to promotions and offers.

What are Wagering requirements?

Wagering requirements indicate how often you have to wager the bonus (or the bonus plus your deposit amount) before you can request a withdrawal of your winnings. With wagering requirements, an online provider makes sure that you will be visiting and playing for a longer period.

You can often recognize good casino bonuses by the amount of the bonus rollover. Wagering requirements indicate the number of times you need to rollover a bonus amount before you can withdraw your winnings. For example, if you get a bonus with 25x wagering requirement, you have to bet the bonus amount 25 times before you can make a withdrawal request.

The wagering requirements are even more important than the amount of the casino bonus, because at the end they decide whether you have a good chance of actually getting real money from the offer. A 400% casino bonus is not particularly useful if the bonus terms are inappropriate.

Also check whether the wagering requirements are just for your bonus money or from both the bonus and your deposit amount. Many casinos apply the wagering requirements to the sum of the deposit and bonus, which makes these conditions twice as high as for casinos that only use the bonus amount as a basis.

By tying bonuses to wagering requirements, casinos protect themselves from money laundering and against players opening accounts only to tap welcome bonuses. Nevertheless, wagering requirements must still be reasonable. You should consider whether you want to meet the wagering requirements, as this means that you will stay with a casino for longer. The best online casinos offer wagering requirements between 20x and 40x.

Other conditions

Since there can always be additional terms, we recommend that you read the online casino’s terms and conditions (T&Cs apply) and bonus terms carefully before accepting a casino offer. Common conditions to watch out for:

  • Certain conditions often have to be met within a certain period of time. A good example is casinos where you have to reach wagering requirements within 7 days or less. This restriction makes it much more difficult to achieve the conditions.
  • Game contributions to wagering requirements: Often, bets on certain types of games do not count at all, such as roulette or live casino games. Some casino games, like the particularly lucrative table games, are excluded from the fulfilment of the wagering requirements. But this makes sense actually. Imagine a player in the roulette could, for example, bet the same amounts on red and black (and a smaller amount on 0 as insurance) and thus unlock the bonus amount in no time.
  • As long as you use a bonus, you must not exceed a certain maximum bet, to rule out bonus fraud. A good example is the maximum amounts you can bet with an active bonus in the casino. For most providers, these are around 5 euros per game.
  • Free spins can only be used on selected games only (for example 20 free spins on Starburst).
  • Free spins and Free bets usually come with a max winnings cap and a short expiration period. Usually free spins expire after 7 days and in some occasions even just after 24 hours.

The bottom line is that the percentage (%) and maximum bonus amount (€ / $ / £) you can get, does not tell whether the casino bonus is good or bad. Only in connection with the terms of the bonus can you decide whether the offer is really good and worth it for you.

So, you see why a good understanding of the bonus terms is so important. It is far from pleasant to win hundreds of euros with a casino bonus and then get these winnings withdrawn from the casino. So read the information in this section carefully and also make sure that you read through the individual bonus terms in the casino of your choice.

Finding the Deals: Slots Bonuses checklist

Gambling on the Internet can be a lot of fun and, with a little luck, it can also be very profitable. However, you should play only on a legal and reputable slots site that you can fully trust. Always try to choose a trustworthy casino with a good bonus and a valid license. In this bonus checklist we have summarized the main points for you:

  • Mobile casino: If you like to play on your smartphone or tablet; the corresponding bonus casino should offer a mobile app or the option to play directly in the browser. It is also important to choose the games that are offered for the mobile bonus casino. Always check if there enough mobile slots available? Otherwise, slots bonuses don’t matter.
  • Payment Methods: Usually you have to deposit some real money on the casino and then get your bonus. To do this, you should have enough payment options, especially the ones you use on the Internet. So, can you take advantage of the casino bonus via a depositing through your preferred method?
  • Language: Playing with slots bonuses not in your language is not a good idea. In addition to the menu navigation, the general terms and conditions, and the bonus requirements, the casino site should be available in a language that you master. When selecting slots bonuses, always check whether support and bonus conditions are available in your language.
  • Games: Can you play all of your favourite games with the casino bonus? This is a very important question when choosing the right casino bonus. The number of different providers is now so large that you will definitely find a site that offers your favourite video slot games. Because what does the best slots bonus bring if you have to wager it on slots you don’t like?

Types of Slots Bonuses

There are several types of casino bonuses offered to real money players. These generally apply to specific scenarios, like the first deposit. The purpose of these bonuses is to reward players and encourage them to bet. Winnings can be withdrawn in adherence to the wagering requirements in the terms and conditions (T&C s apply).

Free Spins

Free spins are a very popular slot site bonus offer. With them you can play for free at slots that have been selected by the casino beforehand. In order to impress potential players in particular, some online casinos also offer free spins with a particularly high value per round.

No-Deposit Bonus

A casino no deposit bonus is, as the name suggests, a casino slots bonus for which you don’t have to deposit anything. You can get it either when registering to a new online casino or as a bonus, for example via customer support service or a VIP loyalty program.

Welcome Bonus

If you make your first deposit in an online casino, you can look forward to a welcome bonus. This is either a simple percentage deposit bonus or a welcome pack. A deposit bonus is a money bonus. This bonus is expressed by a percentage, because your own deposit is increased by a certain percentage.

For example, if you get a 100% bonus, your deposit will be doubled. This 100% bonus, is also called as a matched bonus, since the provider matches your deposit. A welcome pack includes some free spins or free bets.


Casinos love to see their players spinning the wheels as much as possible. That’s why they use to organize tournaments. In a standard tournament, the target is to make as much profit from a selected slot as possible. A real money jackpot will be spread out among the top players.

High Roller Bonus

Online casinos are businesses and as every other they like high roller players. That’s why you will see special promotions for players who want to deposit a large amount of real money. So if a standard welcome bonus is up to $200, for high rollers it can exceed $1.000. Sometimes high rollers bonuses come with better terms as well.

Reload Bonus

Bonuses are not only for new players, but also for loyal existing ones! They receive some offers which often are reload bonuses. It’s a way to trigger players to make some deposits.

Game-Specific Bonuses

The iGaming industry is blooming. Not only new online casinos open every day, but also new game and software suppliers. These companies are now a big part of the ecosystem and for new game releases or special events they offer some exclusive bonuses. For example, they offer free spins to be used on selected games. Some times you could find those slots bonuses with attractive wager conditions. This way you can enjoy some small wins after some games played.

Loyalty bonuses

Many online casino providers have VIP and loyalty programs for their players. In order to motivate their customers casinos offer various rewards for each level their players reach. The higher they climb the VIP ladder, the more lucrative the bonuses are. They can get cashbacks, free spins, free bets, even some real gifts as tickets for concerts, or sport matches etc.

Cashback bonus

Since we talk about cashback, you can already understand that this kind of bonus, is for existing players only. Players which reached a certain deposit level, can get a small reward in the form of a cashback bonus. For VIP’s this bonus can be wager-free, while for norm is that cashback bonuses, which can vary from 1% up to 20% or even 30%, come with the standard bonus terms and conditions.

Refer-a-friend bonuses

The more the merrier is the slogan for every casino provider. And the best way to make it happen is to motivate existing customers to bring their friends. These motivation tactics include wager-free cash (up to $100 for every player you bring), free spins, free bets, VIP points etc..

Percentage Deposit Slots Bonuses

Percentage deposit bonuses are very common in the industry. They add extra funds to players accounts based on their deposits. In many cases, the percentage exceeds the standard 100%. Mainly for high roller deposits. This way customers are encouraged to deposit more at once and get a better deal.

100% casino bonus / deposit bonus

With a 100% slot bonus, for example, you deposit € 100 and receive a further € 100 from the casino. So you play with a total of € 00. This is the case if the casino bonus is as follows:

100% up to € 100

The 100% casino bonus is the most common casino bonus offered by online casinos. It is called a match bonus because the casino “matches” your own deposit. So, it provides the same amount as the one you deposit. Your deposit will be doubled. Incidentally, the “up to” means that you can also deposit less and then this amount is doubled by the casino. This way, you can get a nice casino bonus balance for yourself even with a small budget.

In any case, pay attention to the wager required of the casino bonus. Do these relate to the money you get from the casino? Or the sum of your own deposit and the bonus money? This makes a difference of 100% here. The lower the wagering requirements, the better the bonus is, since you will have more chances to meet the conditions and keep part of the bonus, or the whole bonus plus some winnings.

When the bonus is subject to 35x wagering, and when you only refer to the bonus money, you have to play games worth €100 times 35, that means €3.500 (40 × €100) Here, of course, everyone has to determine for themselves whether it’s worth it and whether you want it. Otherwise you have the option at practically all casinos not to accept the casino bonus and simply to play with your own deposit.

200% slots bonus / deposit bonus

The 200% casino bonus is particularly worthwhile. Here, your own deposit is not only doubled, but tripled. So, for example, you deposit € 100 and play with a total of € 300. This is the case if the casino bonus is as follows:

200% up to € 200 welcome bonus

It is important that you understand this information correctly. With this type of casino bonus, the amount of money is the amount that the casino will give you. So, you have to do a little math. With a casino bonus displayed as follows, 200% up to €100, the casino would grant you 200% of your deposit amount. However, only up to the sum of €100. Specifically, this means that you would deposit €50 here to take full advantage of the bonus.

Note that in some occasions those kind of bonuses come with some bonus spins as well. For example: 200% up to € 200 plus 200 bonus slots. The 200% slots bonus is not as common as the match bonus mentioned earlier. Nevertheless, there are some online casinos that offer this bonus amount. Usually the amount that the casino grants you is a little lower. So, if you have a lot of money that you want to use, a match bonus may be more worthwhile for you. However, if you play on a smaller budget, you can of course particularly benefit with a 200% casino bonus.

The following also applies here: pay attention to the wagering requirements and the slot bonus terms and conditions (T&Cs apply). For .example, if the casino counts only the bonus amount towards play-trough, or if it is the whole sum (Bonus money + deposit amount) which makes a huge difference.

300% slots bonus / deposit bonus

If you are very lucky, you may even find a casino with a 300% casino bonus. Such offers are very rare, but are extremely worthwhile for the player. Just imagine: you deposit € 100 and play with € 400. Your first deposit is quadrupled with this offer. It will make your start in the casino a lot easier. If you find such a great casino bonus, it could look like this, for example:

300% up to € 300

With this offer, you could receive a maximum bonus of € 300. This means that to make maximum use of the offer, you would have to make a deposit of € 100. This would then be tripled for the full bonus amount of € 300. With wagering requirements of 40x, however, you would have to wager a total of € 12.000 in the casino to unlock the bonus and convert it into real money. This is of course a large amount, so as always, you should carefully consider the amount of your casino bonus. It may make sense to only use part of the casino bonus to make it easier to meet the wagering requirements.

As mentioned, such offers are of course very rare. Few casinos are so generous that you give them a 300% bonus to start with. Nevertheless, there are some of them that you can of course also find them here at Betandslots.

400% slots bonus / deposit bonus

Last but not least, we still have the 400% casino bonus. This offer is even rarer than the 300% casino bonus. If you could find such a bonus, for example, you would deposit €100 and play with €500. The deposit is therefore quintupled, which is a really fantastic offer. In this case, the casino bonus is displayed as follows:

400% up to € 400

Deposit 10 play with 50 slots bonus is rare. So you can let off steam with a small deposit amount at the slot machines and table games of the casino. With wagering requirements of 40x, however, you would then have to wager a whopping €16.000 in the casino. This is the only way to successfully implement the bonus. As you can see, such great offers should always be chosen carefully. For example, if you deposit only €50, you will receive a bonus of € 200 and can play with €250. The wagering requirements would then be halved and would “only” amount to €8.000.

How to Get a Slot Bonus Deal

Getting a casino bonus is easy. If you are unfamiliar with how slot promotions work, here’s a simple guide to walk you through:

  • Step 1: Choose a casino. Select from our list above and see which one offers the best bonus to suit your playing needs. Betandslots provides all important terms so you can make compare the offers. Remember that for those on a smaller bankroll, free spins bonuses are most appealing.
  • Step 2: Register and open an account. You can take advantage of a bonus, but first you need to create your account. Provide the details needed. Remember, they need to be accurate, because in case of winning you will need to provide documents in order to withdraw your money! Remember that fully licensed casinos must ask for prove of identity.
  • Step 3: Activate the slot bonus. Some slot bonuses, such as no deposit bonuses or free spins, can be activated immediately with your registration. Other (also no deposit, or Free Spin bonuses) require a specific promo code – if you are unsure contact the casino customer support and they should help.
  • Step 4: Make a deposit. In most cases, especially for the most attractive and most generous slots bonuses, such as deposit or matched deposit bonuses, you must make a deposit. Visit the cashier, choose your preferred banking method, and make a deposit in order to receive your desired bonus. You can make a direct bank transfer, or use a prepaid, or cash, or credit (not in the UK) card as a proxy between the casino and your bank account.
  • Step 5: Start spinning! Once you have made your deposit and got your bonus, you can enjoy yourself. Start spinning and remember to fulfil the wagering requirements before asking for a pay-out.

Slots bonuses FAQ

Online casinos want to lure you and convince you that they can give you the best gambling experience. Most of them offer a welcome bonus that multiplies your first deposit and often also has some free spins attached. But be careful, there is usually a catch.

There is no one that gives away real money for free. Online slot sites also have no money to give away. Therefore, slot bonuses always come with certain conditions. And it is important to meet wagering requirements before profits can be paid out. Basically, it is always worthwhile to read the bonus conditions carefully before deciding for or against a casino bonus.

An online casino bonus is a bonus that, depending on the type, is credited to you for a registration, participation in a special promotion or a deposit into your casino account. It can be a sum of money or free spins. You use the bonus just like regular money in your casino account.

No, of course no! You don’t necessarily have to take any casino bonus. Many players appreciate the fact not having to deal with complicated bonus terms and simply play with their own money. No wagering requirements headaches and no maximum bets limitations. It is simply a choice whether you prefer simplicity or you prefer to maximize your winning chances.

Some online casinos use bonus codes to activate a slots deposit bonus. This is a bonus code, for example BONUS01 or something similar, which you enter into a field provided for this purpose. Your bonus will then be activated. Bonus codes can be found particularly often in reload bonuses or to distinguish a deposit for an action from a regular deposit.

Don’t be afraid. Even if you accept a casino bonus and fail to meet the wagering requirements, nothing serious will happen. As soon as you have used all bonus money, you have no other obligations. This means that with your next deposit, you no longer have to meet any wagering requirements. At least until you get another bonus again.

Many online casinos also offer free spins as part of their welcome bonus. These usually come for a specific slot game. Usually you receive a message that states that some free spins have been credited to you. If you didn’t get them, but you think that you should have them, contact customer service.
