This bet is the same as a Trifecta bet in that you are betting on three horses coming in first, second and third place. However, a Trifecta Box bet means that the three horses you picked can finish the race in any order. They only need to place in the top three positions for you to win. This bet is basically 6 bets in one. For example: you place a $3 trifecta box bet on horses number 4, number 6 and number 7. There are six possible outcomes for these three horses to finish in first to third place; therefore, the total amount of the bet is $18. You win your bet if horse number 4, number 6 and number 7 finish in first, second and third place of any order.
