The amount of money people can place on a single online slots bet will be restricted for the first time as part of a wider government overhaul to tackle gambling addiction.
A £5 per spin limit will apply to all adults aged 25 and over with a £2 per spin limit for 18 to 24-year-olds.
The Department for Culture, Media and Sport (DCMS) is also set to introduce a statutory levy on gambling companies to help fund addiction treatment.
It said the measures would allow people to “gamble safely” but the betting industry’s main lobby group said the government was “at risk of losing perspective”.
