As some casinos will give the best bonus right on your first deposit, and others might require several deposits to unlock the offer, the casino with the best offer here will change depending on the amount you enter. Bonus Awarded ? Total bankroll figures depend on the way the casinos award their bonuses. A casino might offer the same bonus as another overall, but will require 1, 3 or several deposits to reach the full reward.

What to look for to get the best bonus for you

It’s really important to understand that even the best bonuses come with some strings attached. The good news is you can (and should) read the fine print from top to bottom before any kind of signup or bonus redemption. Just look for the Terms and Conditions associated with the offer to get down to the nitty gritty. Ask yourself these key questions to stay protected:

  • What Users Asked

    How much of my deposit will the bonus match?

    Expert Advice

    50%, 100%, 200%, looking for a high percentage means you can boost, match or even double your deposit it amount.

  • What Users Asked

    Are there any other important conditions?

    Expert Advice

    The time to find out if there are any other conditions on your deal is BEFORE you accept it.

  • What Users Asked

    How do I max out the value on my bonus?

    Expert Advice

    The best online casino bonuses offer extras like free slots spins and other giveaways on top of the cash amount.

How Do Match Bonuses Work?

Almost all types of casino bonus in 2018 operate using what’s typically referred to a bonus percentage. This number, almost always in the range of 50-200%, refers to how much of your deposit amount you’ll get back as bonus cash.

The second number in an online casino bonus, preceded by “up to”, refers to the maximum amount the casino will give back in bonus funds for making a real money deposit.

This can be a little confusing if you’re not used to match bonuses, so let’s look at a real-world example of a casino online bonus to figure everything out.

Example: Bonus Percentage of 200% up to $300

A deposit of $50 with 200% match
(the rest of the bonus amount expires)

Deposit $50
=
Bonuses $100

A $150 deposit with 200% match.
(the full bonus amount has been met)

Deposit $150
=
Bonuses $300

Watch Out For The Small Print!

Before you accept a bonus, you’ll want to examine all the ins and outs of how it works:

Checking for things like the site’s wagering requirements, conditions of how and when you have to make deposits, which games count towards clearing wagering requirements etc. will help you to get the best out of a welcome offer and score the most bonus cash possible.

Are there any additional online casino bonus conditions to check out?

Are there any additional online casino bonus conditions to check out?

You’ll also want to take a look at how long you have to clear wagering requirements and when you can withdraw your casino bonus as real money. Sites that offer the best online casino bonuses are VERY transparent and won’t hide any of this information away from you or try to trick you into making a mistake.

Don’t forget to enter promo codes where applicable, as if you fail to do so you may lose out on your welcome offer entirely!

How Do Wagering Requirements Work?

Wagering requirements refer to the amount of money you need to bet before you can convert bonus funds into real money.

They usually range between 20x and 50x the value of your initial deposit and/or bonus cash you’re being awarded, so getting lower wagering requirements can make a big difference if you’re a casual gambler.

Let’s take a look at a real-world example:

$100 Bonus
bonus with wagering
requirements of 10x bonus value
10x$100

amount
You need
to bet
$1000
To release

Casinos also impose restrictions on things like how long you have to clear wagering requirements, how much you can bet and which games you can play using bonus cash.

Are Other Promotions Available?

Casinos need lots of traffic to be successful and reach the top, so they’re always eager to attract new players. As a result, any sign up bonus designed for newbies in 2018 is sure to be far and away the most valuable.

However, the best sites do offer added extras like the odd no deposit bonus, free spins on certain slot machines, giveaways and promotional entries into tournaments to keep existing players from straying too far.

If you stick with one specific casino online you may also be able to get some mileage out of their loyalty program, or perhaps even their VIP scheme if you gamble enough, with various freebies and extras on the proverbial table.

Frequently Asked Questions

What are casino bonuses?

An online casino bonus is a reward, offered as an incentive, whether it be sign up, loyalty or deposit based, to play the ames at any given gambling site.

How do they work?

It depends on the site you are visiting. Offers will always vary in such a crowded market place, which is why we do the hard work for you and search out the best bonuses on offer. For the most part, you will need to invest some real money of your own at some point in order to release your winnings. However, most bonuses do at least provide you with money to play with beyond your initial bank roll.

What are bonus codes, are they different?

While most online casinos offer you an immediate bonus to play, some may require an activation code which they, or us, will provide you with. Once this code is entered into the correct box on its intended site, the bonus is activated.

Are they worth it?

Of course! We want you to enjoy the best possible gaming experience and the more value you squeeze from your online casino, the more fun you'll have. Whichever casino you choose, the bonus will be worth collecting. If you're searching for the best online casino bonuses available across the web, then check with us first.

What casino games can I use them for?

That will be stated when you agree to claim a bonus. All, or most, online casino games offer specially tailored and bespoke bonuses relevant to what their players require. That means you get to enjoy games like blackjack, baccarat, roulette, slots, poker and video poker whilst gaining free money in the process.

Are they just for new players?

Sometimes but not always. Online casinos value your custom and often provide loyalty bonuses and further rewards for depositing funds along the way.

Are they available for mobile play?

Most of the time, yes, a mobile casino will offer bonuses.

How do I find the best bonuses?

With us, of course. We work hard ensuring that the bonuses we recommend are relevant, up to date and in your best interest.

Are the biggest bonuses usually the best?

Not necessarily, no. They might look impressive but may require more outlay from your pocket in order to release the bonus on offer. Read the small print and make certain you understand exactly how each offer works.

How long does it take to receive my bonus?

As long as you fulfil your required commitment, more often than not your online casino bonus will activate instantly.

Can I withdraw my bonus?

Sometimes, yes. Sometimes, no. Once again it depends entirely upon the sites you use and the types of bonus you are attempting to cash in on. Some sites may allow you to invest a certain amount of real money before withdrawal, others may insist that all winnings are collected minus the bonus. It really is worth getting to know your bonus types and making sense of the industry terms. Once you understand the various types of online casino bonus available, you are in a good position to make an informed decision.
