Under-25s Protected with £2 Maximum Bet Per Spin
The UK government's consultation on a maximum stake limit for online slots games has resulted in clear age-based limits coming into effect. The mandatory stake caps went live on May 21, 2025, after being introduced as a mandatory licence condition for remote casino operators.
The new rules, created under the Gambling Act 2005 (Operating Licence Conditions) (Amendment) Regulations 2025, limit maximum stakes on online slots to £5 per spin for adults aged 25 and over, and to £2 per spin for adults aged 18 to 24.
This statutory limit approach followed the government consulting on stake cap options including sets of £2, £5, £10, and £15 per spin along with providing extra protections for younger adults through either a £2 limit, a £4 limit, or requiring age-based risk mitigation. The consultation lasted from August to September 2023, with analysis concluding that online slots posed a risk of major losses, frequent sessions, and loss-chasing behaviour.
The government highlighted the neurological and economic vulnerabilities of younger adults in its rationale for lowering their stake limits, citing factors such as ongoing brain development, lower disposable incomes, and managing finances for the first time.
The mandatory stake limits became a firm condition for remote gambling operators under Great Britain's regulatory regime in April and May 2025. This dual-stage introduction was designed to protect consumers from online gambling harms that the government said are linked to the readily accessed high-risk slot machines.
The stake limit policy was unveiled as part of the wider reforms to gambling regulation under the Gambling Act 2005, including the creation of a statutory levy to fund research, education and treatment. But the age-based fixed stake caps represented a central change intended to mitigate significant financial and behavioural risks, particularly for younger players.
The Gambling Commission has published guidance on the new online slots stake limit rules, which make clear that the £5 cap applies to every individual game cycle, not as an overall session limit. It has also confirmed the split £5 / £2 level and noted operators must alter their systems by the May 21 deadline for the under-25 customer cohort as well.
