A Special bonus is a no-deposit or deposit match bonus which is usually linked to a specific event. It can be awarded on a certain date, e.g. Birthday or Anniversary Bonus, or after fulfilling certain requirements, such as posting comments on the casino’s social network pages, finding mistakes on the casino website, or sending verification documents. In some cases, the special bonuses are awarded for deposit via a certain payment method, e.g. Skrill or Neteller.
