Care has been speaking out after the All-Party Parliamentary Group (APPG) on FOBTs published its final report of a six-month inquiry.
Following growing disquiet among politicians about the harm being caused on Britain's high streets by the machines, the MPs have recommended a cut in the maximum stake.
The high-stake, high-speed electronic casino games have been branded "the crack cocaine of gambling" by campaigners, who argue that they are dangerously addictive.
Care's Director of Parliamentary Affairs, Dr Dan Boucher, who gave evidence to the APG committee, said: "In a context where this Government has rightly set the goal of Britain working for everyone, it is clear that FOBTs don't really fit the narrative.
"FOBTs certainly work for the bookmakers, but not for problem gamblers, their families or society as a whole. The recommendations this report makes are therefore very welcome and urgently needed."
He added that the government had to "act now" to cut the maximum stake.
The Association of British Bookmakers (ABB) warned such a move would be a "hammer blow" to high street bookies and threaten thousands of jobs.
Chief executive Malcolm George said: "This is a deeply flawed report funded by vested interests who would directly benefit if its recommendations are ever implemented.
"Betting shops are already closing at the rate of more than 100 a year and if the findings of this rigged report are implemented, it could spell the beginning of the end for the high street bookmaker."
