The superfecta is a type of wager in the United States and Canada parimutuel betting in which the bettor, in order to win, must pick the first four finishers of a race in the correct sequence.
This is even more unlikely than a successful wager in the trifecta, which requires correctly picking the first three finishers in order, and as such will have a correspondingly higher payoff.
This 10 cent bet is very popular with the fans as it permits a bettor with a small bankroll to cover many combinations and still have a chance for a large payoff.
For instance, the New South Wales TAB in Australia previously offered a superfecta bet on selected races requiring bettors to pick the first six finishers in the correct order, rather than four.
This type of wager is called quadrifecta in Brazil and cuatrifecta in Argentina and Uruguay ("quad-fecta").
