A Banker is an available function for a multiple bet. Next to each selection appears the letter B.
If you consider a match prediction to have the highest probability of success, you may select the Banker. In this way, a system bet will consider the Banker as guaranteed and all other sporting events will be directly combined with it.
If your Banker bet is a winner, your ticket odds will increase. If it is not, the entire ticket will be lost, regardless of the other results.
