There is hereby created in the state treasury a special nonreverting fund to be known as the Gaming Regulatory Fund, referred to in this section as “the Fund.” The Fund shall be established on the books of the Comptroller. All funds appropriated for such purpose and any gifts, donations, grants, bequests, and other funds received on its behalf shall be paid into the state treasury and credited to the Fund.

Any moneys remaining in the Fund, including interest thereon, at the end of each fiscal year shall not revert to the general fund but shall remain in the Fund.
