If your bet is successful, we will add a boost of 5 - 70% to your winnings. The boost amount is dependent on the number of selections. Boost is paid as cash and added to your withdrawable balance. Bets placed with Bet Credits do not qualify for this boost.
However, winning too often will see your account with bet365 restricted. This is why bookmakers don't like professional gamblers who consistently win. It is bad for business, and bookmakers are out to make money, not lose them.
