How are Casino Bonuses Calculated?
Almost all casino bonuses in 2023 operate using what’s typically referred to as a bonus percentage. This number, which is 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 the words “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 matching bonuses, so let’s look at a real-world example to figure everything out:
Example: Bonus percentage of 200% up to $300
| Deposit | Bonus | |
|---|---|---|
A deposit of $50 with 200% match (the rest of the bonus amount expires) | $50 | $100 |
A $150 deposit with 200% match (the full bonus amount has been met) | $150 | $300 |

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 the 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:
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.
What other casino promotions exist?
Real money casinos need lots of traffic to be successful, so they’re always eager to attract new players. As a result, the latest bonuses designed for newbies in 2023 are sure to be the most valuable.
However, the best sites do offer added extras for existing players like:
- No deposit bonuses
- Free spins on certain slot machines
- Giveaways
- Promotional entries into tournaments
If you stick with one specific online casino, you may also be able to get some mileage out of their loyalty program, or perhaps even their VIP scheme, if you gamble enough.
Casino bonus terms & conditions
Before you accept an online casino bonus, you'll want to double check the fine print. We can't stress enough how important it is that you read the T&Cs of the bonus offer. You'll especially want to find this out:
- 1What the minimum deposit for the bonus is
- 2If there's a time restriction on using bonus funds
- 3Whether there are promo codes to enter
- 4Which games are included in the bonus offer
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 get the most out of a welcome offer and score the best casino bonus possible.
Are there any additional online casino bonus conditions to check out?
You’ll definitely 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.

Frequently asked questions about bonuses
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 games at any given gambling site.
How do online casino bonuses work?
How casino bonuses work varies. For some you will need to invest some real money of your own to earn the bonus, but you can get no-deposit bonuses just for signing up. They might be bonuses of money to wager, free spins to play with, or free coins. Read our breakdown of the types of bonuses you can earn.
What are bonus codes and are they different to bonuses?
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. The bonuses we recommend don't need bonus codes and are activated in the link you click.
Are online casino bonuses worth it?
Of course, we think the bonus is usually well worth collecting. If you're searching for the best online casino bonuses available across the web, we know where to look.
What casino games can I use bonuses for?
That will be stated when you agree to claim a bonus. All, or most, online casinos offer specially tailored and bespoke bonuses relevant to what their players require. That means you get to enjoy casino games like blackjack, baccarat, roulette, slots, poker and video poker whilst gaining free money in the process.
Are casino bonuses just for new players?
Sometimes bonuses are aimed at new casino players, but not always. Online casinos value your custom and often provide loyalty bonuses and further rewards for depositing funds along the way.
Are casino bonuses available for mobile play?
Yes, and there are even some fantastic casino bonuses which are exclusive to those playing on a mobile device. A mobile casino bonus can come in many different forms, ranging from no deposit bonuses to free spins at some of the best online slots. While the rollover requirements differ from casino to casino, nearly all are worth taking advantage of when you first start using a mobile device to play.
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. You can read through our 25-step review process to learn exactly how we rate casinos.
What makes a good bonus?
It depends. A good casino offer should suit how you play, how much you play, and work with your preferred game. Check out the different types of bonuses and compare offers from different casinos.
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. Check the terms and conditions of the bonus before you sign up to make sure though.
Can I withdraw my casino bonus?
It's not that common, but once again it depends on 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.
