Trifecta odds are bets placed on the three best finishers in a race, and they have to be in the exact order. You have to bet on the win (first-place horse), place (second-place horse, and show (third-place horse). Trifecta bets are some of the most challenging ones to win. However, if the odds are in your favor, the payouts are so profitable that they surpass those of exacta and quinella bets.
