 of the number of entries in each race. For example, if there are ten entries in the first race and eight in the second, there will be eighty betting interests, one for each combination of two potential winners. This results in higher payoffs than those found in straight betting for win, place, or show.

For many years the daily double was the only exotic wager offered. Later the exacta was also offered on select races during each program. The wagers were offered only a few times each day largely because of the limitations of electro-mechanical totalisator systems. When computer technology took over, more exotic wagers were introduced, such as the trifecta

The word comes from the related betting term, "perfecta". A trifecta is known as a tiercé in France and Hong Kong and as a tris in Italy.It...

 and pick 6. The higher payouts for these wagers tended to diminish interest in the "old fashioned" daily double, but it is still offered at all tracks, sometimes more than once during a program. A "late double" is frequently offered on the day's final two races; some tracks offer a "rolling double" - a daily double starting on each race on the program except the last race.

The "Pick 3" and "Pick 4" wagers are derived from the daily double. These wagers require bettors to pick the winners of three or four consecutive races. These are also often offered on a rolling basis — a rolling pick 3 on races one through three, another on races two through four, and so on throughout the day.

Occasional doubles are offered on important races contested on separate days. The most prominent example is the "Oaks-Derby Double" offered by Churchill Downs
