Casino slots vs arcade machines

Casino slots vs arcade machines: the short answer

Every gaming machine in a British venue belongs to a category, and the category sets the maximum stake, the maximum prize and where the machine may be sited. Casinos can host the widest range, including the highest-limit Category B1 machines. Arcades split into two very different kinds of venue: the adult gaming centre, which is for adults only and can offer some Category B machines, and the family entertainment centre, which is limited to Category C and D.

The Gambling Commission’s gaming machine categories (opens in a new tab) set out the limits below. They have not changed since the Category B2 stake cut of 1 April 2019, and the government’s May 2024 response on land-based gambling kept them as they are.

What casino slot machines are allowed

B1 machines are the closest thing in Britain to a Las Vegas slot: £5 a spin, prizes up to £10,000, and progressive jackpots linked between machines on the same premises up to £20,000. Only casinos may host them. Casinos can also offer B2, B3, B4, C and D machines. Our page on casino slot machines covers what you find on a typical floor.

How many machines a casino can have depends on its licence. Under section 172 of the Gambling Act 2005 (opens in a new tab), a large casino may have up to 150 machines and a small casino up to 80, in each case no more than five times its number of gaming tables. The five-times ratio for small casinos applies from 22 July 2025, when it replaced two times. Older casinos licensed under the 1968 Act have a default of 20 Category B to D machines, and from 22 July 2025 can take an extended entitlement of up to 80, on a sliding scale tied to their gambling area and table numbers.

What arcade machines are allowed: AGCs vs FECs

An adult gaming centre can offer Category B3 and B4 machines up to 20% of its total machine count, plus any number of Category C and D. Because it offers Category B machines, it is an adults-only venue. The government announced in May 2024 that this would become a ratio of two Category B machines for every C or D machine, but as at 21 October 2026 the 20% cap in section 172 still applies. Venues licensed before 13 July 2011 may keep four B3 or B4 machines, or 20%, whichever is greater.

A family entertainment centre is different. A licensed FEC may offer any number of Category C and D machines; an unlicensed FEC, run under a permit, may offer only Category D. Category C machines are 18+ wherever they are sited. Seaside and holiday arcades are usually FECs, sometimes alongside a separate AGC area. The Commission’s summary of machine provisions by premises (opens in a new tab) lists every entitlement, and our FEC and AGC rules page explains them.

Age rules: casino slots vs arcade machines

Categories B and C are 18+ only, so every casino slot and every AGC machine is adult-only, as are the Category C fruit machines in a family arcade. Category D is the exception: it has no statutory minimum age at present. Since 2021 the industry body Bacta has applied a voluntary ban on under-18s using cash-paying Category D slot-style machines. On 16 May 2024 the government said it would make it an offence to invite or permit under-18s to use those cash-out machines, as recorded in the written ministerial statement (opens in a new tab), but no regulations creating that offence had been made as at 21 October 2026.

This site writes for adults. Category D machines that pay cash work like small slot machines, with a stake, a random result and a prize, and they cost money over time. Our pages on Category D age rules and whether under-18s can play arcade machines give the detail, and the guide for parents covers questions families ask.

What 100 plays cost on casino and arcade machines

Machines in Categories B1 to C must display a theoretical target return to player, and Category D machines must too, except crane grabs and penny falls. No minimum percentage is set in law. The average cost of play is stake × plays × (100% − RTP), so read the figure on the machine and do the sum. The table uses a 90% return purely as an illustration; real machines vary.

Higher-category machines are not more generous because they allow bigger prizes. They let more money pass through each play, so the cost per hour rises with the stake. Multiply your own stake and the machine’s displayed percentage the same way to see your figure.

Paying in and collecting on venue machines

The Gaming Machine (Circumstances of Use) Regulations 2007 (opens in a new tab) apply in casinos and arcades alike. They set how play works:

1. Pay in by cash or ticket. A single payment in is limited to £20 on Categories A to C and £2 on Category D. Machines may not be designed to take debit or credit cards, and phone wallets count as the card.
2. Commit to play. One action may commit up to £10 on Categories A to B3A and £5 on B4 and C.
3. Play each game separately; the result is decided by the machine’s software.
4. Collect wins. Wins over £50 on A to B3A, over £10 on B4 and C, and any money prize on D must be collectable rather than forced back into credit.
5. Take a break before fetching more money; where a digital top-up removes that break, the operator must build one in.

The government decided in May 2024 to allow direct debit card payments on machines once protections such as a £100 transaction cap and a 30-second transaction time are in place. That change was not in force as at 21 October 2026. Many venues use ticket-in, ticket-out systems instead; see do slot machines take cards.

Online casino slots vs arcade and casino machines

‘Casino slots’ often means online slots too, and these follow different rules. Online slots are not in the machine categories. Stakes are capped at £5 per spin for players aged 25 and over (from 9 April 2025) and £2 for 18 to 24-year-olds (from 21 May 2025), there is no legal prize cap, and every game must take at least 2.5 seconds per spin with no autoplay or turbo. Accounts come with deposit limits, time-outs and GAMSTOP. Free demo play is available only after age verification. Our page on online vs land-based slot machines compares the two in full.

Testing and the new machine standards

Category B1, B2 and B3 machines must be tested by an independent test house approved by the Commission before use. The Commission published new gaming machine technical standards on 30 September 2026: an interim standard defining a gaming machine ‘session’ comes into force on 30 March 2027, and the final standards on 30 June 2027. Trade press reports that new Category B machines will then need player limit-setting and displays of time played and net position, and that new A, B and C machines will lose turbo and slam-stop features and may not celebrate returns that are equal to or less than the stake. Existing machines are reported to be exempt. Our page on gaming machine technical standards tracks the detail.

Myths about casino and arcade machines

• ‘Casino machines pay out more than arcade machines.’ They allow bigger prizes, which is not the same as a better return. Read the displayed percentage; see do slot machines pay out more in casinos than pubs.
• ‘Coin pushers are just games.’ A pusher with money prizes is a Category D gaming machine with a stake and a prize; see are coin pushers gambling.
• ‘Crane grabs are fixed so you can never win.’ Crane grabs are Category D machines with a £1 stake and £50 prize limit, and are exempt from displaying a return; our page are crane grab machines rigged explains what is known.
• ‘A machine that hasn’t paid out is due.’ You can’t see where a machine is in its cycle, and other players have fed it first.

Self-exclusion and help for casino and arcade play

Online, GAMSTOP blocks you from every UK-licensed site at once. In venues, self-exclusion works through schemes run for each sector, so you register with the casino, the AGC operator or the local scheme covering the arcades you use. The Commission’s self-exclusion page (opens in a new tab) explains the options, and our guides on arcade self-exclusion and help for slot players list contacts. The National Gambling Helpline, run by GamCare, is free and open 24 hours on 0808 8020 133.

Verdict: casino slots or arcade machines, by type of player

If you want the highest land-based limits, only a casino offers B1. If you prefer modest stakes, an AGC or a Category C machine keeps each play smaller, though the cost still adds up. If control tools matter most, online play offers deposit limits and time-outs that venues can’t.
