Montana Lottery Halts Millionaire Sales After System Failure

Only 12,919 of 720,000 available Montana Millionaire tickets sold before the lottery halted sales on Sunday morning due to a system failure. The error forced terminals across the state to stop feeding tickets, leaving many customers waiting in line until the postponement was announced around 11 a.m.

The disruption occurred shortly after sales opened at 5:30 a.m. Terminals displayed error messages stating that transactions were not allowed. Lottery Director Bob Brown explained that the system experienced performance issues caused by the high volume of transactions. The state and vendor Bally’s Intralot had tested the new central gaming system earlier this year. Brown said those tests simulated a sales rate approximately double the highest previous Montana Millionaire sales volume.

Brown noted that the team believed they were ready for the expected demand. However, the system struggled to process the real-time load. Brown declined to provide specific technical details on Monday about what caused the shutdown. He stated that the state and Intralot have identified a fix and are currently testing it to ensure it is ready before bringing the game back online.

The glitch altered the odds of instant wins for the tickets sold that morning. More than 2,000 of the 12,919 sold tickets were instant winners. This included 991 tickets winning $100 and 1,019 tickets winning $500. This result created a winner ratio of roughly one in six, compared to the expected ratio of one in 74. Brown confirmed that all instant wins from Sunday will be honored. Tickets sold that day remain valid for the final drawing in December.

To maintain fair odds for future buyers, the lottery will add more instant wins back into the game. This adjustment means the state will pay out up to $600,000 more in prizes than originally expected. Brown said Intralot will cover this additional cost. He described the vendor’s decision to step up and take on the expense as the right thing for people.

Brown apologized for the delay, acknowledging that stopping sales sooner might have been better in hindsight. He said the team initially tried to implement simple fixes to resume sales quickly. They only postponed the game after determining that was the best option to protect the system.

The lottery has not set a specific date for resuming Montana Millionaire sales. Brown said leaders want to give retail partners and the public enough time to prepare. He emphasized that the system will undergo multiple successful test runs before it goes live again. The game has seen growing popularity in recent years, with 620,000 tickets sold out in just over six hours in 2025.
