If you play online bingo, then you have more than likely taken advantage of some sort of bonus. If you have not yet done so, then the time to do so it now. One type of bonus offered is known as a Refer a Friend Bonus.
As the name hints, this bonus is given when you refer one of your friends to the bingo site. Simply referring them is not enough. They must also sign up with the site and play a certain number of games. Bingo sites like rewarding their loyal customers and offering refer a friend bonuses are one way that they do this.
Generally, the bonus will be given not only to the referring friend but the friend who signs up for the site. Also, as a new member, the friend will be eligible for other bonuses as well. By referring a friend, you make it possible for you to play bingo with many of your friends.
