What is a banker?
Bankers are events that you are certain that you are going to win on. When you choose some event/s to be your banker/s, only combos containing the selected banker/s will be placed. Example: you have selected 4 events in your bet slip. With no bankers chosen, you will be offered to place 1 standard 4-fold combo (containing all four events), 6 Doubles and 4 Trebles. When you have selected one banker however, you will be offered to place only 1 standard 4-fold combo, 3 Doubles and 3 Trebles – only the combos in which your banker participates. If you have chosen 2 bankers, you will be offered to place only 1 standard combo and 3 Trebles. It is not possible to combine only bankers and therefore in the last example you are not offered a Double.
