A type of a bookmaker's promotion.
It is quite a common type of promotional offer. Here, tipsters do not only compete against the bookmaker, but also against each other, which brings out even more emotions and, therefore, satisfaction. Usually, punters have to keep on betting to collect ranking points, however, it is not always the case. Sometimes, all you need to do is to opt-in for a free-to-play contest at the official bookmaker's website. The reason betting contests are so popular among punters is impressive prize pools, cash rewards and even VIP ticket packages for the most popular sporting events.
