Notwithstanding any other provision of law, the South Carolina Lottery Commission may enter into a multi-state agreement for the sale of instant game tickets, online game tickets, and related multi- state lottery products including game shows and promotional products. Procedures for ticket sales and validation, prize redemption, and other details of the commission's participation in the multi-state lottery games must be governed by the terms of the agreement entered into by the commission.
