A box trifecta bet allows you to select as many runners as you like to finish first, second and third (in any order). Use the list below to calculate the costs of aR$1 unit box trifecta on the Melbourne Cup (halve if using a 50-cent unit):

The +  and -  are put in front of odds or lines, indicating the favorites and underdogs. The favorites will be marked with a minus sign, whereas underdogs have the plus sign. This is the case for all types of bets, including moneylines and point spreads.
