Using alternative drawing formats.
Except for enhanced raffles, licensees may use alternative drawing formats that randomly determine winners if licensees:
(1) Fully disclose to each player the random selection process used in the alternative drawing format before selling tickets; and
(2) Maintain a copy of the disclosure with the permanent raffle records; and
(3) Use controls and accounting procedures that:
(a) Provide the ability to audit gross gambling receipts from ticket sales; and
(b) Have sufficient controls to prevent manipulation of the random selection process; and
(c) Document the random selection process.
