A Tote Trifecta is where you are betting on horses to finish first, second and third in a particular race. You can place a straight trifecta, a single bet where you select the horses to finish in the first three in your chosen order. A combination trifecta is where your horses can finish in any order in the top three for you to win but consist of more bets as you are covering multiple lines. The last bet is a banker trifecta, where you pick a specific horse to finish first, then select the second and third horses that can finish in either order.
