What are Casino Bonuses?

A casino bonus is a promotional offer given out by online casinos. The easiest way to relate it to every day life is to think of it like a coupon.

A casino will give you a coupon upon joining to give you a better chance of winning by providing you will either free money or free spins on slot games.

Why use a Casino Bonus?

A bonus promo allows the player to easily double, triple or even quadruple their starting balance at the casino. Thanks to the bonus you can play with higher bets on the casino games and get bigger payouts in return.

In the end, even if you lose your entire balance you will lose only a fraction of real money than you would if you played without a bonus but with the same balance.

For example, you make a $100 deposit and claim $200 in addition as bonus money. If you lose you only lost $100, instead of $300 of real money if you wanted to deposit and play with the same amount.

It’s one of the main reasons why a player will create an account and make a real money deposit. The maths is simple. The better the bonus promotion is, the bigger bets you can place and therefore increase your chances of winning big.

Casino Bonus Types

There are dozens of different casino bonuses as online casinos get more creative attempting to attract new players.

We will focus on the most important which are the only ones you need to know about as they satisfy 99% of all casino players.

Free Spins

Free spins are a slot lover’s most preferred play option. This type of bonus gives you free credits to use when playing online. Keep in mind that the bonus only applies to specific titles and not the entire casino. This shouldn’t bother you because these games are often the most popular ones. A typical promotion would be something like 30 Free Spins or 50 Free Spins. It’s extremely rare to see a huge offer such as 100 Free Spins but if we ever do, rest assured that 5bestcasinos will list it!

No Deposit Bonus

As a way to get you playing, some casinos are happy to let you have a small amount of free money without requiring you to deposit any funds. This usually isn’t much, something like $10 No Deposit Bonus is the most common but it’s enough to place a few bets on the house and get a feel for the casino. Be warned, you can’t withdraw this money if you win with your $10 as there will be wagering requirements associated with a no deposit bonus, but that’s cool we still like it!

Match Bonus

A match bonus will match up the amount you deposit and grant you that amount as extra cash to use. You can use the bonus amount freely and deposit as much as you like, up to a certain threshold, which is usually very generous. Match bonuses are most commonly part of the welcome offer also known as a sign-up bonus.

Welcome Bonus

Free Play is another concept altogether. You are given free cash to use and try to win something extra. Your winnings will be capped at a certain point, meaning you can only withdraw a certain amount, no matter how much you end up winning. The bonus amount itself won’t be part of your final balance.

VIP & Loyalty Bonus

VIP & Loyalty bonuses are great ways to make sure that you are being rewarded for your persistence and love for gaming. By being a loyal customer, the casino will keep rewarding you in the form of exclusive bonuses designed specifically for your particular needs at the time of reward.

Reload Bonus

Reload bonuses are additional incentives that are usually granted at the discretion of the casino. Some Reload Bonuses are part of regular promotions as well and they are implemented in the casino to give you a little in the way of a leg-up. Overall, a reload bonus is a great way to keep your bankroll topped off.

Best Casino Bonus for Slots

Many players search for slots casino bonuses as they look for specific terms and conditions which favor playing mostly slot games.

As online slots are the most popular casino game it is no coincidence that all casinos focus their offers on slot players.

Clearly if you are looking for a slots casino bonus then you would automatically be attracted to the highest free spins offer.

However, we would recommend a welcome bonus package that offers you a good percentage on your deposit plus free spins. So something like a 300% match bonus plus 100 free spins is perfect for slot players.

How We Find the Best Casino Bonus Offers

Finding the best online casino bonuses takes time. Some casinos choose to offer just a handful of promotions whereas others will make sure that you can access every last single one of these bonus types.

In both cases, to determine whether a bonus is worth your while, you take a closer look and examine the specifics of each individual offer.

Finding the best casino bonus is a matter of being able to read through the offer and consider its upsides and downsides.

No one is as prepared to do this as our insightful industry experts who are aware of the industry’s standards and can tell you at a glance whether a bonus is worth the effort.

Understandably, our casino experts go much deeper than a glance.

The Small Print you Need to Know

Before you make a real money deposit at a casino and claim a bonus it’s best to familiarize yourself with the bonus terms.

This will help you decide whether the bonus in question is worth claiming. You will also find out what your chances will be to wager it and make a withdrawal.

Here are some of the most common bonus terms you can come across at the best online casinos

Wagering Requirements

Picking the best casino bonus offer comes with a few provisions that you will need to acknowledge and agree to before you can enjoy it.

Let’s face it – many casino customers end up complaining, because they never bother with the small print, the all important terms and conditions.

We know that you are a better class of player and understanding what the playthrough requirements are is part of making educated choices and influencing your game in the best possible way as well.

3 main points you should be on the lookout for:

  • Playthrough 
    Each bonus needs to be “played through” a specified number of times before you can withdraw it from your casino balance
  • Deadline 
    A use-by date which tells you how soon you have to be done with the playthrough requirement

  • Wagering Contributions 
    Not necessarily part of the bonus, the wagering contributions tell you what amount of your stake counts towards the bonus

These terms seem rather easy to understand and they are, but there are a few extra caveats that we would want to draw your attention to first.

Let’s take the playthrough requirement. It can be applied to only your bonus amount or deposit and bonus amount both.

With this in mind, it’s always worth making sure you’ve read the terms and conditions. A 20x or even 30x playthrough may seem a treat when you are only wagering the bonus amount, but if that factors the playthrough, then you will have to agree that it’s a bit steep.

Maximum Allowed Bet per Spin

The maximum allowed bet per spin is especially important for players who make a bigger deposit.

This allows them to claim a big bonus and play on higher bets. At most casinos, the maximum allowed bet per spin is $5.

Some operators allow a maximum bet as low as $1 or in correlation with the deposit or bonus amount, for example 10% of the bonus amount.

If you like to make big bets, make sure that the bonus you want to claim allows you to do so.

Can you Cash Out the Bonus?

At most online casinos you can withdraw your entire balance once you manage to clear the water. But some casinos offer players a Sticky or Non-Cashable bonus.

This bonus is awarded for wagering purposes only. This means it will be deducted from your balance once you make a withdrawal.

For example, you claimed a $200 bonus and managed to make a $500 withdrawal. But you will only receive $300 in real money since the bonus amount is non-cashable.

This is why it’s recommended to claim a cashable bonus every time you can, so look out for this in the terms.

Allowed Casino Games

Every online casino will have a list of allowed or forbidden casino games which you can play with bonus funds.

This protects the casino from players who claim a big bonus amount and wager it on low variance and high RTP slots without losing too much of their balance.

This is why usually games like these don’t allow you to play with bonus funds.
