Fixed-odds maximum bet 'could drop to £2'
The maximum stake for fixed-odds betting terminals could drop to as little as £2 under a government review.
Currently, people can bet up to £100 every 20 seconds on electronic casino games, but ministers are considering a new limit somewhere between £2 and £50.
The consultation aims to reduce the risk of people suffering large losses and to tighten up advertising rules.
The Association of British Bookmakers said the onus was on the gambling industry to help cut problem gambling.
According to a government consultation, cutting the stake to £2 would cost the industry over the next 10 years.
But problem gamblers say it is time for action to be taken - including, but not only, lessening the amount they can lose in one hit.
Gambling vlogger Andrew Margett told BBC Radio 5live how the machines, also known as FOBTs, proved addictive: "I was just in a trance, in a complete bubble, playing it. Hitting the button, hitting the button, hitting the button."
As part of the government review:
- The Gambling Commission - the industry's regulator - will consult on changes to protect online players.
- Broadcasters, advertisers, industry and support groups will draw up an advertising campaign to promote responsible gambling, with an annual budget of up to £7m.
- New advertising guidelines will be drafted to protect problem gamblers, children and young people.
- Access by under-18s to gambling content and channels on social media will be restricted.
- Gambling companies are being told to step up funding for research, education and treatment. If they don't, operators may face a levy.
Culture minister Tracey Crouch said current laws on gaming machines - which critics have called the "crack cocaine of gambling" - were "inappropriate".
"It is vital that we strike the right balance between socially responsible growth and protecting the most vulnerable, including children, from gambling-related harm," she said.
"We have seen online gambling grow rapidly and we need to protect players in this space, while also making sure those experiencing harm relating to gambling receive the help they need," she said.
But in an urgent question session in the Commons, shadow culture secretary Tom Watson said the government was kicking the issue into "the long grass" and added that action, rather than a consultation, was needed.
"There's an old maxim that the bookies always win, and they've won again today," he said.
Mr Watson, who is also Labour's deputy leader, claimed that 450,000 children are gambling on a weekly basis.
Labour wants a new gambling bill to look at the explosion of digital and online products - to stop children gambling on phones and to protect vulnerable people.
Carolyn Harris MP, who chairs an all-party parliamentary group on the issues involved, said there was overwhelming evidence people's lives were being destroyed by the machines.
"When you see the statistics that 31% per cent of people who use these machines are earning less than £10,000... Where do they get the money? Because they are not earning it," she told the Victoria Derbyshire programme.
The government began to look again at gambling in October 2016, when it made a "call for evidence" on the number and location of gaming machines and the measures in place to protect players.
Fixed-odds terminals were introduced in casinos and betting shops from 1999, and offer computerised games including roulette and blackjack at the touch of a button.
The government is consulting on 11 different types of gaming machine, with stakes ranging from 30p to £5. Each machine accepts bets up to a pre-set maximum and pays out according to fixed odds on the simulated outcomes of games.
'Reducing FOBT odds is a matter of principle', by Amol Rajan, media editor
Like every other industry, gambling has been radically transformed by technology. The advent of smartphones has made gambling much easier, more convenient, and constantly present than it was before. For centuries, gambling was for the most part an activity or habit that you had to move towards. Now, thanks to the internet, the gambling comes to you.
It is dangerous to reduce the debate of FOBTs to one about economics: how much is raised in tax revenue; potential job losses; the impact on our high streets and so on. It is rather also a question of principle.
In a free or liberal society, is it reasonable to let fully informed adults of sound mind make their own decisions about how to spend - and yes, waste - their money? Perhaps it is; but it becomes intolerable when this freedom harms others.
It seems that public opinion has moved to the view that negative social consequences and harm have flowed from the gambling industry's tendency to cluster in areas of deprivation and high unemployment.
Malcolm George, of the Association of British Bookmakers, said the government shared its wish to identify problem gamblers and get them help.
But restricting terminals in betting shops would redirect problem gamblers to other avenues where there were fewer controls on the amount of gambling, he said.
"Just as alcohol policy in this country is not solely determined by alcoholics" he added, there needs to be an environment for the "vast majority who gamble responsibly".
The British Amusement Catering Trade Association's John White said the government needed to "strike the right balance", but stakes should be "quite substantially" reduced, he said.
Asked about job loss fears, he said half of high street adult gaming centres had disappearing since FOBTs were introduced.
Tax law changes in 2001 led to a vast increase in the number of terminals.
By 2005, about 20,000 terminals were in use and more than 34,000 are now found across the UK, according to the Gambling Commission.
