| Many gambling operators use a refer a friend program as a method to try and increase the number of players signing-up for accounts at their online casino. The promotion offers existing customers the opportunity to receive refer a friend bonuses for recommending a casino to someone they know. Unlike other offers, a casino refer a friend scheme doesn’t require you to spend any real money and you and your friend will receive a bonus amount when they sign-up for a new account. Many casinos also give you the bonus offer on more than one occasion, rewarding you for every friend you refer up to a specified amount. There are usually terms and conditions attached to each refer a friend bonus, although these are generally not as restrictive as other casino bonus offers. The bonus amount is usually credited to both parties as funds you can use to play casino games, although some operators give the existing customer a cash payment they can withdraw immediately. The Casino Billions team love refer a friend casino offers and has worked hard on your behalf to produce this in-depth guide that shows you how they work.
