A System Bet is a way to increase your possibilities of winning. You can place a system bet by entering at least 3 selections on your bet slip. For example, a 2/4 has 6 possible winning pairs (1st team X 2nd team or 1st team X 3rd team etc). You win even if only two of the four predictions prove correct. The winning amount is different on every case based on the odds of your selections.
