This wager requires the player to pick the runners that will finish the race in first and second in either order. Many racetracks no longer offer this wager, although where it is available it is popular. The player normally plays the top two favorites in the race. This wager also can be played with the runners other than the favorite. This method would result in higher payouts to the player if the runners come in.
Some racetracks offer only a few races that have the trifecta wager.
Others offer every race as a trifecta as long as the race has a minimum of six runners. Many players will box more then three horses for the trifecta, but one must realize that with each addition of a marginal horse the cost grows rapidly. The exacta marginal horse may not be worth the extra cost. The twin trifecta is a very exciting race. The player must pick the first three finishers in two consecutive races.
