Four machines, and a rulebook that changed underneath them
The terminals along the wall of a betting shop are the most heavily rewritten part of the British high street gambling estate. They arrived in 1999, and the Gambling Commission counted 33,319 of them in betting offices between October 2011 and September 2012. The rules on what they may take per play were then rewritten twice in five years: a decision in May 2018 cut the maximum stake on certain content from £100 to £2, the change was delayed, and it finally took effect on 1 April 2019. A shop may hold up to four terminals in total, and that ceiling counts older-style slot machines as well, which is why the machine wall in almost every chain looks the same length. Everything on this page describes the legal frame around the machines. None of it is a description of any particular terminal in any particular branch, because we have not stood in front of one.
Four rules that hold whichever fascia is above the door
A shop cannot opt out of these, and a chain cannot compete on them. That makes them the most reliable thing anyone can tell you about a machine, and it is why they are worth knowing before you read a single word of promotional copy.
The cap counts everything
Shops are allowed up to four terminals, and traditional slot machines count towards that number. The limit is on the premises, not on the brand, so a bigger shop does not get more of them.
The stake ceiling is statutory
The reduction to a £2 maximum on certain machine content was a government decision taken in May 2018 and applied on 1 April 2019. It was not a courtesy offered by any operator, and no shop can quietly restore the old level.
The return figure must be shown
A terminal is required by law to display its theoretical return to player. Published reference figures put slot-style content in the region of 90 to 94 per cent and standard roulette content around 97 per cent, but those are long-run averages across enormous numbers of plays, not a forecast for an afternoon.
Time and money prompts exist
A facility for customers to set time and money limits on these terminals was introduced across the sector in 2014. It is easy to walk past, and it works considerably better before a session than during one.
