UK online slot stake limits

What the UK online slot stake limits say

The limits come from the Gambling Act 2005 (Operating Licence Conditions) (Amendment) Regulations 2025, which add a new condition to every remote casino operating licence. The Gambling Commission's online slots stake limit guidance (opens in a new tab) sums up the effect: the most an individual may stake per game cycle on an online slot is £5 if they are aged 25 or over, and £2 if they are aged 18 to 24.

Because the limit is a licence condition, it applies to every operator offering online slots to players in Great Britain, including licences issued before the regulations took effect. It sits alongside the rest of our UK casino bonus rules and the older slot game design rules on autoplay and spin speed.

What a 'game cycle' means for the stake limit

The limit is set per game cycle rather than per click. The regulations define a game cycle as running from the moment a player starts a game until either all the money staked has been lost or all winnings have been delivered or made available to collect. If a game offers further staking opportunities inside the same cycle, they count towards the same limit.

The Commission's guidance works through scenarios. In one, a 27-year-old stakes £2 at the start of a cycle; the game may then offer further stakes in that cycle of up to £3, bringing the total to £5, but nothing more. In another, a player who is offered a prize can accept it, ending the cycle, or turn it down to gamble for a bigger prize. Because the player isn't asked to stake any additional money in that choice, the limit isn't breached.

The guidance doesn't separately address bonus rounds or free spins features inside a slot, so check a game's help screen for how its features work. It also repeats the existing rule that at least 2.5 seconds must pass between the start of one game cycle and the next, a requirement set out in the Commission's responsible product design standard, RTS 14 (opens in a new tab).

Which games the stake limits cover

The limit applies to online slots, which the regulations define as casino games that are reel-based and played online. 'Reel-based' is wider than it sounds: it covers games that display moving or changing images or text, whether on visual reels or by other means, where you can win a prize based on the resulting arrangement. That catches classic three-reel games, Megaways slots and most themed video slots.

The guidance states that the limits don't apply to other casino games, such as roulette or blackjack. Those games have their own design rules, including a minimum of five seconds per game cycle since January 2025, but no stake cap under this regulation. Our table games bonus page explains how bonuses usually treat them.

How the stake limits came about: timeline

The limits were one of the headline measures in the 2023 white paper, High stakes: gambling reform for the digital age (opens in a new tab). It proposed consulting on a stake limit of between £2 and £15 per spin, with a lower £2 or £4 option for young adults. After consultation, the government announced on 23 February 2024 that the limits would be £5 and £2, in a release headed new £2 maximum stake for under-25s playing online slots (opens in a new tab). That release expected a September 2024 start, but the limits actually began in spring 2025.

Why the UK capped online slot stakes

Online slots are fast, continuous games, and before 2025 there was no stake limit at all online, while high-street machines had been capped at £2 since 2019. The white paper's concern was that very high stakes on slots could lead to large losses in short periods, and that young adults were a group at particular risk. The lower £2 limit for 18 to 24-year-olds reflects that concern.

The limit doesn't change a slot's return to player or house edge; it limits how much can be lost on each spin. At £5 a spin, 100 spins put £500 at stake; at £2, the same 100 spins put £200 at stake. With a 96% RTP, the average cost would be about £20 and £8 respectively, though any one session can differ widely. Our RTP glossary entry explains why these are long-run averages.

Stake limits and bonus max-bet rules

Most deposit bonuses have their own maximum bet rule, and it sits on top of the legal limit. Whichever figure is lower is the one you must keep to. For a player aged 25 or over, a bonus that allows £5 per bet matches the legal limit on slots. For an 18 to 24-year-old, the legal £2 limit is lower, so the bonus allowance makes no difference on slots.

Casumo's welcome offer is a useful example. Its terms set a maximum of £5 per bet while a bonus is active. A 30-year-old playing slots can stake up to £5; a 22-year-old can stake no more than £2, whatever the bonus says. The Casumo max bet page covers that offer's terms in full.

Breaking a bonus max-bet rule can lead to bonus winnings being removed under the offer's terms. The legal limit works differently: operators must stop further staking once your band's limit is reached in a game cycle.

How stake limits change the maths of clearing wagering

Lower stakes don't change the total you need to wager, only how many spins it takes. Take Casumo's maximum bonus: a £200 deposit brings a £100 bonus, and 10x wagering means £1,000 of bets within 7 days. At £5 a spin that is 200 spins; at £2 it is 500. With the 2.5-second minimum per spin, 500 spins need roughly 21 minutes of play at the very least, and realistically much longer.

The average cost depends on the total wagered, not the spin size. £1,000 of slot bets at a 4% house edge costs about £40 on average, whether that is 200 spins of £5 or 500 spins of £2. Smaller stakes do make results less extreme from session to session. Our guide on how to calculate wagering requirements shows the method for any offer, and the 10x wagering cap page explains the limit on wagering itself.

Free spins and the stake limits

Casino free spins are almost always set at a fixed stake well below both limits. All three of our partners' spin offers use 10p spins, so 100 spins are £10 of play and the stake limit never comes into it. Free spins also can't be resized: you play them at the value the casino sets. Our page what stake are free spins played at explains spin values, and the coin value entry covers how a spin's total stake is built up.

Where the limit can matter is after the spins. If no-wagering spins pay out in cash and you go on to play with that money, each spin must still respect your band. Lower stakes stretch the same balance over more spins, but they don't change the average cost per pound wagered.

How to check which stake limit applies to you

1. Make sure the date of birth on your account is correct; it is verified when you sign up.
2. If you are under 25, expect slots to cap your stake at £2 per game cycle.
3. Open the bonus terms and find the maximum bet while a bonus is active.
4. Use the lower of the two figures as your ceiling on slots.
5. Contact support if the stake options don't match your age band.

The guidance doesn't spell out how operators move a customer from the £2 band to the £5 band at 25. In practice, the verified date of birth on the account is what operators go on, which is one reason age verification before play matters. The question can under-25s claim bonuses covers the bonus side.

What the online slot stake limits don't cover

• Table and live games. Roulette, blackjack and other casino games have no stake cap under these regulations.
• Deposit amounts. The limit is per game cycle, not per day or per deposit. Deposit limits are a separate tool you set yourself.
• Losses over time. Many small stakes can still add up; the limit slows losses but doesn't stop them.
• Northern Ireland and unlicensed sites. The licence condition applies to operators licensed in Great Britain. Players in Northern Ireland or on unlicensed sites don't get the same protection.
