Allwyn Resolves National Lottery Tech Glitches

Key Takeaways:

• Technical issues post-upgrade disrupted ticket sales but were resolved within days, restoring near-full functionality.
• The Momentum ecosystem enhances security and efficiency, supporting the lottery's £2 billion annual good causes funding.
• Regulatory oversight emphasizes technology's role in maintaining player trust and operational integrity.

Allwyn has addressed widespread technical glitches affecting National Lottery terminals across the UK, following a major software upgrade earlier this month. Retailers reported intermittent failures in ticket sales and prize validations, prompting urgent interventions to restore full operations. The issues, which emerged shortly after the transition to Scientific Games' Momentum ecosystem, underscore the challenges of modernizing one of the world's largest lottery networks but also highlight Allwyn's commitment to minimizing disruptions for its 43,500 retail partners.

The upgrade, completed in August 2025, marked the most significant technological overhaul for the National Lottery since its 1994 launch. It involved migrating to a new central gaming system, updated terminal software, and enhanced data security protocols, aimed at accelerating transactions and improving player experiences. However, the rollout led to glitches that temporarily halted services at select locations, with some retailers experiencing delays in processing draw-based games like Lotto and Euro Millions. Allwyn's operations director, Jenny Blogg, confirmed that a dedicated support team worked around the clock to deploy fixes, ensuring 99% of terminals were operational by September 29. This swift resolution prevented prolonged revenue losses and maintained contributions to good causes, which exceed £30 million weekly.

The incident arrives amid Allwyn's broader transformation strategy, initiated after assuming operations from Camelot in February 2024. The Momentum platform, provided by Scientific Games, now powers retail, digital, and instant-win products, incorporating advanced features like real-time inventory tracking and AI-driven personalization. Industry analysts note that while teething problems are common in such large-scale migrations—the largest in global lottery history—the upgrades position the National Lottery for sustained growth. Participation rates remain robust at 29% for draw tickets in recent surveys, but seamless reliability is crucial to retaining trust among the 45 million annual players.

Regulators, including the UK Gambling Commission, monitored the situation closely, emphasizing participant protection in a September 23 speech by CEO Andrew Rhodes. He stressed that robust technology is integral to the lottery's societal role, funding arts, sports, and heritage without compromising integrity. Allwyn's proactive response, including enhanced retailer training and contingency plans, aligns with these priorities, averting potential scrutiny.

Looking ahead, Allwyn plans further enhancements, such as expanded digital wallets and contactless payments, to boost accessibility. For retailers, the upgrade promises faster checkouts and reduced downtime, potentially increasing footfall. As the lottery navigates this digital evolution, resolving these glitches reinforces its resilience, ensuring continued support for vital community initiatives.
