Online Casino Referral Bonuses

Referral Bonuses Intro Icon

Online casinos are like any other business; they want lots of customers. And they know that, very often, word of mouth is the best promotion. That’s where the online casino referral bonus comes in. 

An internet casino knows that if they have a good product, their customers are willing to recommend it to their gambling friends, especially if they get something in return.

This is how refer-a-friend offers work: an online casino customer recommends the site to a friend. If their friend signs up and deposits, the customer gets a reward.

Here we will explain these offers in detail, list the top online casinos that have them, and tell you how to claim an online casino refer-a-friend promo.

What is a Refer-A-Friend Offer?

What Is a Casino Referral Bonus Icon

A refer-a-friend bonus is awarded to online casino customers who get others to sign up and play. Sometimes called Tell-a-Friend or Invite-a-Friend, these are popular promotions casinos use to get new players.

Customers usually claim the casino refer-a-friend offer by sending their contacts a unique link or code by email. They get paid when a new player signs up and deposits. 

The online casino referral promotion usually has wagering requirements you must clear before withdrawing the bonus money. Online casinos have different rules on these rollovers or the number of people players can refer.

Although many online casinos offer them, referral promotions are not as common as online casino welcome bonuses.

How To Claim A Refer-A-Friend Promo

If you need help claiming your referral bonus, here’s a step-by-step guide that will allow you to do it without any issues.

  1. Go to the Online Casino’s Promotions Tab

    Sign in to the online casino and navigate over to the Promotions tab. Look for the Refer-A-Friend promo and read the rules or terms of the offer to make sure it suits you.  
  2. Enter Your Friend’s Details and Send the Invite

    You must fill out a form with your friend’s contact details, including name, address, and email. In some cases, you may have to email your friend a link or code.
  3. You Can Also Use Social Media

    Sometimes, an online casino referral deal will appear on a site’s Twitter, Facebook, or other social media, and you can click to get a form.
  4. Receive the Bonus Funds

    The casino has to process your friend’s information, which will take as long as their sign-up and deposit process. Then, the site will get the money to you ASAP. It may take more than a day, depending on the casino.

Referral Bonuses Terms & Conditions 

Below are some factors you should consider when deciding whether claiming a Refer-A-Friend offer is good for you. Make sure to read these in detail before making a referral.

Promo Codes

Some online casinos may require that your friend use a promo code when depositing. This is not the case with any of the offers we recommend on this page, but keep an eye out because other sites may use this method.


In the rules or terms of the offer, you will find playthrough or rollover and wagering requirements. You have to clear these before you can withdraw your bonus money. Many casinos provide a tracker so that you know your progress.

Specific Games

Bonus wagering requirements have different levels of contribution for different types of games. Slots typically count 100% or dollar-for-dollar, while table games count less.

Max Payout and Min Deposit

There are also stipulations for the minimum your friend must deposit and the maximum you can withdraw on the offer. Typically, your friend will need to deposit at least $20 or $25 for you to be able to claim the bonus amount.

Time Limit

There are also stipulations for the maximum amount of time your friend has to make the deposit. It varies from casino to casino but make sure to inform your friend.

Calculate The Value of a Referral Bonus

While in some cases, referral offers are pretty straightforward (for example, you get $100 if your friend makes a deposit), in other cases, you may have to calculate the amount of money you will get.

Many casino offers are divided into two main parts: the match rate and the maximum amount. The site will match your referral’s deposit x3 and will deposit a maximum of $300 in bonus money in your account.

Let’s look at an example.
