From 9 April 2025, the UK Gambling Commission introduced a maximum stake limit on online slot games for all licensed operators:
£5 per spin (game cycle) became the absolute maximum stake for adults.
This applied across all UK-licensed online casinos and effectively capped how much a player could bet on a single spin.
Further change (May 2025)
A second phase came shortly after:
From 21 May 2025:
£2 per spin limit for players aged 18–24
£5 per spin remains for players 25+
