In all races except sweepstakes with five or more separate entries which start, racing associations shall provide win, place and show pools; in all races with four separate entries which start, they shall provide win and place pools; in races of three or two separate entries which start, they shall provide only a win pool; and pari-mutuel tickets shall be sold accordingly; provided, however, that in sweepstakes with less than four separate entries which start, racing associations may, at their option, provide that there shall be no betting; and in such cases an additional race with betting shall be added to the program, if feasible.
