What Is a Refer-a-Friend Casino Bonus?

A refer-a-friend casino bonus is a unique promotional offer that has gained popularity with both operators and players alike, because it’s a win-win for everyone involved!

As the name suggests, refer-a-friend casino bonuses are rewarded to players who recommend the casino site to their friends, who then sign up for an account.

The bonus is usually awarded upon the friend's successful registration and initial deposit. casino bonuses are one of the many ways that online casinos reward their current players for their loyalty to the site, often providing a reward to the friend who signs up as well.

Taking advantage of a refer-a-friend bonus is a great way to boost your bankroll while sharing the fun of playing at your favourite casino with your favourite people!

How Refer-a-Friend Casino Bonuses Work

There are three common ways of sharing this bonus to interested parties. We've included them below:

  1. Share a Referral Code
    This is a unique code that your friend needs to input during the registration process to activate the bonus.
  2. Share a Referral Link
    Another common option is to share a generated link on which any referred individuals can click.
  3. Input the Details of the Friend You Want To Refer
    Here, you'll need to enter your friend's phone number or email address to generate unique registration link that will activate the bonus once they have signed up.

How To Claim a Refer-a-Friend Casino Bonus

Much like other top casino bonuses and offers, refer-a-friend bonuses are simple to claim. Here’s how to find and activate them:

  1. Find a Casino Offering a Refer-a-friend Bonus
    Choosing a casino is the first step, if you're not already signed up to one. Be sure that the site offers a wide variety of games, good customer support, casino banking methods and an attractive array of promotions apart from the refer-a-friend bonus. Always read the terms and conditions attached to the offer to make sure that they are fair, rather than simply basing your decision on the size of the bonus.
  2. Choose a Trusted and Licensed Casino
    It is vital to choose an online casino that is fully licensed and trusted by a leading authority, such as the Malta Gaming Authority or the UK Gambling Commission. You also want to get your bonus from a safe and secure casino that features software provided by top developers.
  3. Get Consent From Your Friend
    Before you refer a friend to your favourite online casino, it is essential that you get their consent before doing so. This is particularly true if you plan to provide the casino with your friend's phone number or email address!
  4. Send the Link or Input the Details!
    Once consent from your friend has been given, both of you can activate the bonus. You will have to send the invitation which your friend then needs to accept. As we mentioned above, you might alternatively have to input your friend’s details yourself. Simply follow your casino’s instructions, whatever the case may be.
  5. Activate Your Refer-a-Friend Casino Bonus
    Once your friend registers at the casino, they will usually be asked to make deposit before the refer-a-friend bonus can be credited to your account.

Different Types of Refer-a-friend Casino Bonuses

There are four primary types of refer-a-friend bonuses offered by today’s online operators. These include:

1. Cash Bonuses
Cash bonuses are the most common type of bonus offered by online casinos – they reward you with real funds that you can then play games with. This is also a common type of welcome bonus across various casino sites.  No deposit casino bonuses generally fall into the cash bonus category as well.

2. Free Spins Bonuses
Free spins
are to be used on slot games. Generally, players will tend to go for the slots with the best RTP, although sometimes the game choice isn’t up to the player, and is instead defined in the T&Cs of the bonus itself.

3. Loyalty Point Bonuses
Some online casinos allow you to earn loyalty points that can move you up to a higher level on the operator's VIP/loyalty programme. These bonuses are another great way to boost your bankroll, allowing to extra funds to use on your favourite slot titles, table games, and live casino games.

4. Non-Casino Rewards
A fourth refer-a-friend bonus type includes non-casino rewards. These are gifts that are not directly linked to real money for use on casino games, and can grant prizes such as online shopping vouchers.

Refer-a-Friend Bonuses vs VIP Programmes

While refer-a-friend casino bonuses and VIP programmes are not the same, they do have one key thing in common. In both cases, the online casino provides you with a reward for demonstrating loyalty to the brand.

The main difference is that a refer-a-friend bonus is a one-off reward for each friend that you successfully refer, while a VIP programme usually consists of a series of tiers where you receive a gift each time you move up.

Refer-a-Friend Bonuses: Important Things To Remember

Now that we’ve covered what to expect with this type of bonus, it’s worth noting a few additional things to bear in mind. Here’s the low-down:

Terms and Conditions

There are going to be specific terms and conditions that apply to each refer-a-friend bonus that you claim. It is important to understand these T&Cs, including points such as the number of friends you can refer, the referral method itself, and the number of people per household that can take advantage of the offer.      

<strong>Limits on Claiming</strong> Limits on Claiming

The majority of online casinos will only allow you to refer one friend – however, there are a few others that will allow you to refer several. This is another key reason to carefully read the terms and conditions for each refer-a-friend casino bonus that you wish to claim.

Wagering Requirements

You should always look carefully at the wagering requirements attached to any refer-a-friend casino bonus. Wagering requirements refer to the amount that you will have to play through the bonus before you can withdraw any of your winnings.

Deposit and Withdrawal Limits 

As with virtually all promotions at online casinos, there are deposit and withdrawal limits that you need to be aware of before claiming a refer-a-friend bonus.

Expiry Dates

A final thing to remember is the bonus's expiry date. You will want to be aware of any time limits that are in place so that you can successfully plan out how you will wager your bonus funds within that period.


Refer-a-friend casino bonuses really are a great promotional opportunity because they serve the needs of everyone involved. The casino benefits from adding new customers, while you benefit from a bonus for making referrals. Often, your referred friends will get a bonus for joining as well.

With our handy list of recommended online casinos included above, you are now ready to go out and find your perfect refer-a-friend casino bonus. We are confident that if you follow the advice we provided, you will soon be enjoying the benefits that come along with this excellent promotion!

Refer-a-Friend Casino Bonus FAQs

Yes, you can! Several casinos offer a refer-a-friend bonus for players in the UK and the rest of the world. See above for our list of casino recommendations to get started.

It is very simple to do. Sign up to your chosen casino and then make full use of whatever referral bonus that the site in question offers. You may need to activate the promotion through a unique referral link or code, or enter your friend’s email address or phone number (after getting their consent to do so).

No. You need to make sure that your casino of choice offers this particular promotion beforehand.

This depends on your preference. It also depends on the type of game you want to play, and the type of casino you have registered to. Always remember to read the terms and conditions attached, too.

These would be Unibet, Maria Casino, and Drift Casino.

This is dependent on the casino itself. Some have a limit, while others will allow you to invite as many friends as you like.

A refer a friend bonus is not the same thing as a VIP scheme. The latter is, however, another great way to boost your bankroll through rewards you receive as a loyal player.

Given how competitive today's online casino industry is, a refer-a-friend bonus is another great way to attract new players.

Generally speaking, the reward will arrive in your account as soon as the friend that you referred has successfully signed up and made their first deposit. Given the fact that additional rules may apply, it is always a good idea to check the specific casino's terms and conditions first.
