How to choose the best casino bonus

It's important to know what you're signing up for when you're looking for a gambling casino online bonus. We asked our members what their most common questions on the best casino promotions were – below is our best advice.

How much of my deposit will the bonus match?

It can be anything from 50% to 200%. Looking for a high percentage means you can boost, match or even double your deposit amount.

Are there any other important conditions?

You should always read the T&C's. The time to find out if there are any other conditions on your deal is before you accept it.

How strict or loose are the wagering requirements?

This varies across the sites. Find out how many real money bets you have to make to be able to withdraw your bonus funds on your casino.

How do I max out the value on my bonus?

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

Types of casino bonuses and promotions

Welcome bonuses

You'll find a welcome bonus casino is very popular with new US players. Welcome bonuses are rewarded just for signing up and will have different strings attached to them from having to wager your deposit a certain amount of times to specific eligible titles.

  • Get a cash reward as soon as you sign up
  • Start your gaming session with a healthy bankroll
  • Have your deposit amount matched by anything up to 200%

No deposit bonuses

Get some cash to play with and try out a casino risk free with no deposit bonuses. These are unsurprisingly a very popular form of bonus as players in the US can play with a bonus without having to deposit any money.

  • Get a bonus now, all without spending your own cash
  • Try out any game you like before choosing to deposit
  • Cash out your bonus once you’ve completed the playthrough requirements

Monthly bonuses & promotions

See your loyalty rewarded with a monthly bonus from casinos who value not only new players, but their returning customers too. These will vary from casino to casino, but expect free spins and bonus cash to play with.

  • Receive a monthly bonus amount to keep up your game
  • A variety of seasonal promotions through the year
  • Get both cash and prizes in return for regular play

High roller bonuses

High roller players get treated to big bonuses for making regular large deposits. These are very rare to come by as they are reserved for casino's top paying customers. As they are so bespoke, we can't give away too much.

  • Work through the tier system for better player rewards
  • Get exclusive bonus rewards to top up your bankroll
  • Enjoy other prizes like gadgets and even holidays

Game-specific bonuses

  • Get other rewards like VIP points and free spins
  • Broaden your player skills, and your bankroll

State-specific bonuses

Online casinos that operate across a number of different US states may offer different bonuses and promos to customers in each state. You can find our curated lists of state-specific casinos below:

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:

$100 Bonus
Bonus amount
10x$100
Bonus with wagering requirements of 10x bonus value
$1000
To release bonus winning

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:

  • 1
    What the minimum deposit for the bonus is
  • 2
    If there's a time restriction on using bonus funds
  • 3
    Whether there are promo codes to enter
  • 4
    Which 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. Sites that offer the best casino bonuses are very transparent and won’t hide any of this information from you or try to trick you into making a mistake.

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

Legal online gambling in the US

You can play at a whole range of legal casinos across the US depending on the state you're in. For many states you can play at social casinos for free and enjoy the casino experience safely and securely. In other states like New Jersey and Pennsylvania, you can legally gamble with real money. Luckily, most casinos offer bonuses whether they offer real money or social gambling.

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 in the US 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 them 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 they available for mobile play?

Most of the time, yes. In fact, many people don’t realise that there are 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.
