The maximum stake on fixed-odds betting terminals (FOBT) will be cutfrom 100 to 2, the government has announced.
The move follows lengthy consultations over the machines, dubbed the crack cocaine of gamblingby critics due to their potentially addictive nature.
Bookmakers have previously claimed movesto slash the maximum stake on FOBTs would lead to the loss of thousands of jobs in the industry.
The government said the new measureswouldcut the potential for gamblers to rack up huge losses and reduce harm inflicted as a result on the wider community.
When faced with the choice of halfway measures or doing everything we can to protect vulnerable people, we have chosen to take a stand, culture secretary Matt Hancock said.
These machines are a social blight and prey on some of the most vulnerable in society, and we are determined to put a stop to it and build a fairer society for all.
