A Trifecta requires you to select the first, second, and third finishers in a race in their exact order.
The selections can also be selected as a Boxed Trifecta, allowing for the first, second and third horses to finish in any order.
If one of the selected runners in a Trifecta is declared a 'non-runner' or is scratched after the wager is confirmed, wagers will be refunded on every combination which includes the scratched runner, and the combination stands and the wager re-calculated without the scratched runner.
In the event of a Dead Heat for any or all of the place getters, there will be as many dividends as there are correct order combinations as declared by the home tote.
