What is a 'Phantom Bonus'?
A phantom bonus, also known as a sticky bonus, is a bonus from an online casino
or sports book
that a customer can use to bet with but can't withdraw. It is added to a customer's account when they first sign up and make a deposit. A company won't advertise it as a sticky bonus but will state something like the bonus is for "wagering only", meaning that a customer can use it to place bets, but they can never cash it out as money.
'Phantom Bonus' Explained
Say, for example, that a customer deposits $100 and gets a $100 sticky bonus. That means he has $100 that is his to lose and a $100 bonus amount. If he bets the full $200 on a team winning at 2-1 and wins, he would win back $300. The £100 bonus would remain in his account for the next bet, but it wouldn't be withdrawable
.Blackjackforumonline.com suggests that players should ignore sticky bonuses if they have a bankroll of less than $2,000. If a player has a bankroll
of between $2,000 and $4,000, they should only take sticky bonuses that are 100% of the deposit or more. The reasoning is that the best way to take advantage of a Phantom Bonus is through the Martingale
system that states on a 50/50 game a player should keep doubling his losses. The Martingale can work well, but only if a player has a large bankroll.Phantom bonuses will have different terms and conditions depending on the betting site. For example, it is doubtful that any site would allow a player to continue winning with a sticky bonus forever. They will lose their validity after a certain date or after the player has won a certain amount of money.
