N.J. Stat. § 5:5-63
The machine, or mutuel board, is also to display the approximate odds on each horse in any race; the value of a $2.00 mutuel ticket, straight, place and show, on the first three horses in any race; the elapsed time of the race; the value of a $2.00 daily double ticket, if conducted, and any other information that may be necessary for the guidance of the general public. Any such machine must be approved by the commission before it may be used, and to prevent a monopoly in the use of any particular machine or type thereof the commission may in its discretion approve the use of any other machine. No other place or method of betting, pool making, wagering or gambling shall be used or permitted by the holder of a permit, nor shall the parimutuel system of wagering be conducted on any races except horse races at the racetrack where such parimutuel system of wagering is conducted, simulcast horse races as provided by the "Simulcasting Racing Act," sections 1 through 12 of P.L. 1985, c.269 (C.5:5-110 et seq.), or simulcast horse races as provided by section 37 of P.L. 1992, c.19 (C.5:5-125).
