This is a shortened and summarised version of this page — we have included key points and important information.
The UK online gambling market is off to a flying start in 2025, posting record figures and continuing its sharp digital trajectory. According to the latest UK Gambling Commission statistics, online gross gambling yield (GGY) for Q1 hit £1.45 billion, up 7% on the same period last year. It’s the kind of growth that signals something bigger than just a seasonal boost.
So what’s driving this surge? A combination of increased mobile activity, major sporting events, and the ever-growing dominance of online slots in the UK. Retail continues to slide, while online shows no signs of slowing down.

Digital Slots Dominate the Market
The big story of Q1 2025 is the continued rise of digital slots, now the engine behind the UK gambling market’s expansion. According to the UKGC, slots generated a record £689 million in gross gambling yield (GGY), accounting for 47% of all online gambling revenue – an 11% year-on-year increase. But it’s not just about headline figures – the real story lies in the behaviour behind the numbers.
- Spins surged to 23.4 billion – up 6% on the previous year
- Monthly active slot accounts hit 4.5 million – also up 6%
- Sessions lasting over an hour rose 5% to 10.1 million
- Average session length remained steady at 17 minutes
This stability in average session time, despite increased engagement, points to a shift in player behaviour. Rather than longer sessions, users are playing more frequently in short bursts – a pattern that fits neatly with mobile-first platforms and modern gamified slot mechanics.
Interestingly, the UK Gambling Commission notes that hour-plus sessions still account for around 6% of total play – unchanged from last year. This suggests a broader player base is fuelling the growth, rather than just intensified activity from existing users. Slots are increasingly embedded into casual routines – something to dip into between tasks or on the go – and that trend is defining their rise.
Modern slot design supports this perfectly. Games are fast to load, easy to understand, and built with looped features, achievements, and unlocks that keep things moving. If you’re looking for a quick spin on the bus or a ten-minute session before bed, most players can get a complete experience in one sitting.
Behind the scenes, operators are refining this even further. AI-driven personalisation is helping match players with the right games at the right time, while enhanced loyalty systems and gamified promotions reward regular play. These tools are keeping players engaged, discovering new titles, and coming back for more.
It’s also telling that the UKGC has begun reclassifying certain games under the slots category to better reflect their mechanics and popularity. This structural change speaks volumes about the genre’s centrality in the market, and it aligns with what the data shows – slots aren’t just a category anymore, they’re the main attraction.
Why Slots Are Winning in 2025
- Accessibility: Mobile-optimised interfaces make it easy to jump into a game anytime, anywhere.
- Engagement: Quick-play formats and personalised offers encourage more frequent sessions without extended playtime.
- Variety: Thousands of themes and mechanics cater to every taste, from classic three-reelers to branded Megaways titles.
- Technology: AI, gamification, and seamless payment tools enhance the entire experience.
- Trust: Clear RTP rates, volatility ratings, and responsible gambling tools help build long-term player confidence.
Put simply, online slots in the UK are more popular than ever, and there’s no sign of that slowing down. The market’s growth is being driven by new audiences, smarter tech, and play styles that work around modern lifestyles. It’s not about marathon sessions – it’s about short, frequent, engaging experiences that fit seamlessly into daily life.
As mobile technology advances and operators continue to fine-tune player journeys, the role of slots in the UK’s gambling ecosystem will only strengthen. Slots are the heartbeat of online gambling in 2025 – and they’re powering a digital revolution that shows no signs of stopping.
Betting Still Strong, but Slots Take Centre Stage
Real event betting (which includes sports) isn’t far behind. GGY reached £596 million for Q1, a 5% rise year-on-year. Interestingly, this came despite a slight fall in the number of bets and active users. It points to higher-value bets or improved bookmaker margins – or both.
Other segments like poker and non-slot casino games stayed flat or dipped slightly, reinforcing the narrative that slots and headline sporting events are the key pillars of current online gambling behaviour in the UK.
What’s Fueling the Growth?

1. The Digital Shift Is Real – and It’s Accelerating
The trend away from high street betting shops has been unfolding for years, but the pace is picking up. Retail GGY dropped 3% to £554 million, while online surged ahead.
More tellingly:
Total online bets and spins rose to 25.2 billion
Retail bets and spins fell to 3.1 billion
With mobile apps offering instant access, quick payouts, and personalised features, the convenience gap is widening. Most major operators have invested heavily in mobile-first platforms, streamlining everything from onboarding to in-game offers.
And with ongoing concerns around retail footfall, cost of living, and shifting social habits, online gambling in the UK continues to look like the default choice for many.
2. Big Events Still Bring Big Money
The Cheltenham Festival remains a betting juggernaut. Each year, it pulls in hundreds of thousands of attendees, and online, the figures are just as impressive. Back in 2022, punters wagered an estimated £500 million on Cheltenham alone – and while full 2025 figures aren’t yet confirmed, early signs suggest similar or higher volumes.
In Q1 2025, bookmaker-friendly results at Cheltenham gave online operators a noticeable revenue bump. With the rise of mobile horse racing bets, especially during major events, festivals like this act as focal points for spikes in both user acquisition and activity.
3. Engagement and Personalisation Go Hand in Hand
More accounts, more spins, longer playtime – the UKGC’s data shows user engagement is rising, not just in volume but in stickiness.
Operators are responding with hyper-personalised experiences:
- AI-driven game recommendations
- Tailored bonuses and promotions
- Gamification features like achievements and leaderboards
- Enhanced loyalty schemes that reward regular play
This kind of personalised engagement not only extends session duration, it also builds loyalty – and it’s proving incredibly effective in a highly competitive market.
4. Regulation Isn’t Slowing Things Down
Despite a tighter regulatory landscape, including stake limits and enhanced responsible gambling rules, the market continues to grow.
Rather than fight the changes, leading platforms have leaned into transparency and player protection. Many now use real-time behavioural monitoring to identify risky play patterns and prompt time-outs, deposit limits, or support tools. These efforts may be boosting consumer trust, contributing to higher participation and longer player retention.
Interestingly, the UKGC recently updated its statistical reporting, separating out slot-specific data to better reflect the sector’s growth and dominance. It’s a subtle but clear acknowledgement of how central online slots revenue is to the industry’s future.
The Retail Slide: Why High Street Gambling Is Losing Steam

The story on the retail side is far less upbeat:
GGY down 3%
Spins and bets down 5%
Major firms like Entain and Evoke have both reported weaker-than-expected retail performance, citing reduced footfall, changing preferences, and broader economic pressures.
The takeaway? For many, the high street just doesn’t compete with the ease and flexibility of mobile gambling. Unless retail experiences evolve to offer something genuinely different or complementary, the slide is likely to continue.
What This Means for the UK Gambling Market in 2025
Digital first gambling is focused on mobile formats
All signs point to a digital-first gambling landscape. Slots are leading the charge, with nearly half of all online GGY now coming from digital slot play. Engagement is rising, technology is improving, and players are responding to increasingly refined, personalised experiences.
Major events like Cheltenham continue to provide tentpole moments for acquisition and revenue, but the bigger story is the shift in how and where people gamble. Retail may still have a place, but it’s becoming the exception, not the norm.
Operators that double down on innovation, personalisation, and transparency are likely to gain the most. Meanwhile, regulatory compliance and responsible play are no longer just boxes to tick – they’re core to building trust and retaining customers.
UK Online Gambling Surge – Final Thoughts
The first quarter of 2025 has cemented a few key truths about the UK gambling industry:
- Digital slots are king
- Mobile is now the default gambling platform
- Big events still drive spikes in betting
- Personalisation and AI are shaping the future
- Retail gambling continues to decline
With the right mix of innovation, responsibility, and customer focus, the UK’s online gambling market looks set to keep growing throughout the year. The sector isn’t just evolving – it’s transforming, with technology and user behaviour driving a profound shift in how gambling is experienced across the country.
Casinos etc. will be keeping an eye on how these trends develop as 2025 progresses – especially the continued rise of online slots and the shifting balance between retail and digital gambling in the UK.
