18- 553 C.M.R. ch. 40, § II-10.0
In purchasing a Play, or attempting to claim a prize in Maine, purchasers and prize claimants agree to comply with and abide by all applicable Maine laws, rules, regulations, procedures, and decisions of the Party Lottery where the Play was purchased, and by directives and determinations of the director of that Party Lottery.
Additionally, the player shall be bound to all applicable provisions in the Mega Millions Finance and Operation Procedures.
A prize claimant agrees, as its sole and exclusive remedy that claims arising out of a Play can only be pursued against the Party Lottery which issued the Play. Litigation, if any, shall only be maintained within the jurisdiction in which the Play was purchased and only against the Party Lottery that issued the Play. No claim shall be made against any other Party Lottery or against MUSL.
Nothing in these rules shall be construed as a waiver of any defense or claim the Party Lottery which issued the Play, any other Party Lottery or MUSL may have in any litigation, including in the event a player or prize claimant pursues litigation against a Party Lottery, or MUSL, or its officers, directors or employees.
All decisions made by a Party Lottery, including the declaration of prizes and the payment thereof and the interpretation of Mega Millions Rules, shall be final and binding on all Play purchasers and on every person making a prize claim in respect thereof, but only in the jurisdiction where the Play was issued.
Unless the laws, rules, regulations, procedures, and decisions of the Party Lottery which issued the Play provide otherwise, a prize shall not be paid upon a Play purchased, claimed or sold in violation of these Rules or the laws, rules, regulations, procedures, and decisions of that Party Lottery; any such prize claimed but unpaid shall constitute an unclaimed prize under these Rules and the laws, rules, regulations, procedures, and decisions of that Party Lottery.
