Indian tribes; event wagering; other events

SB 1777 amends Arizona's lottery statute (ARS 5-554) to clarify rules for state-run lottery games. It explicitly prohibits lottery prizes based on the results of dog races, horse races, tribal gaming activities under the 2021 compact, or any sports/event outcomes. The bill also establishes new requirements for ticket validation, prize distribution (including equal division for tied claims), and adds provisions for special "charitable" instant games with separate accounting. These changes directly affect the Arizona Lottery Commission, authorized vendors, and lottery players by standardizing game operations and restricting certain wagering mechanisms.
