UK online slot stake limits explained

UK online slot stake limits explained: the two caps

Great Britain now has a legal ceiling on how much a single online slot spin can cost. For anyone aged 25 or over the ceiling is £5. For anyone aged 18 to 24 it is £2. A UK-licensed casino must stop you placing a bigger spin, whatever the game and whatever its own settings would otherwise allow.

Before 2025 there was no statutory limit on online slot stakes at all. Each game and casino set its own maximum, and those were often far above £5. The change brought online slots closer to the rules for land-based gaming machines, where the most widely discussed machines in betting shops were cut to a £2 maximum stake in April 2019. For the full list of current rules, including spin speed and bonus caps, see our overview of UK slot rules.

Where the stake limits came from

The limits were one of the headline measures in the government's review of the Gambling Act 2005. The review's white paper, published in April 2023, said online slots needed a stake limit because play is fast, continuous and available at any time. A public consultation that year tested a range of possible caps between £2 and £15, plus a lower limit for young adults.

The government confirmed £5 and £2 in February 2024, and the limits were brought in during 2025 in two stages so operators could update their systems. Our explainer on the Gambling Act review and online slots follows the rest of that story.

The lower limit for young adults reflects evidence that people in their late teens and early twenties are more vulnerable to gambling harm. We explain the reasoning in more depth in why there is a £2 slot limit for under-25s.

What counts towards the £5 or £2 limit

The cap applies to the full cost of one spin, sometimes called the total bet. That is the amount taken from your balance when you press spin. It is not the coin value and it is not the bet per line.

This matters because slot bet settings can be confusing. A game might show a coin value of 10p, a bet level of 5 and 10 lines. Multiply them and the spin costs £5. Another game might show a stake of £2 but add an optional extra bet that raises the real cost to £2.50. If you are under 25, that £2.50 spin would breach the limit, so the game should not let you place it.

• Line bet × number of lines: a 25-line game at 20p per line costs £5 per spin.
• Coin value × coins × lines: check the total, which most UK games now show clearly next to the spin button.
• Optional extra bets such as an ante bet: the extra cost is part of the spin, so the whole amount must fit under the cap.
• Bonus-funded spins: a stake paid from bonus money is still a stake on an online slot, so the same limit applies.
• Promotional free spins: these come with a fixed value, such as 10p, which is well below either cap.

Feature buys are not offered to players in Great Britain, so you cannot get around the limit by paying a large one-off sum to enter a bonus round.

How a casino knows which stake limit applies to you

Every UK casino has to confirm your age before you can deposit or play, including free demo games. That check records your date of birth, and the casino uses it to set your stake limit. The page on age checks on slot sites explains how that verification works.

When you turn 25, your verified date of birth means the £5 limit should apply. You do not need to request it. If a game still restricts you to £2 after your birthday, contact the casino's support team, as there may be a delay in a particular game updating.

Using someone else's account to get a higher limit, or letting a younger person use yours, breaks the casino's terms and can lead to the account being closed and winnings withheld. Accounts are personal, and the limit follows the verified person who owns them.

What the stake limits mean per hour of play

A per-spin limit sounds modest, but slots are quick. UK rules require at least 2.5 seconds per spin, which still allows up to 1,440 spins an hour if you press continuously. Many people play more slowly, so the table uses 600 spins an hour as a more typical pace, and a 96% RTP, meaning the average cost of play is 4% of the amount staked.

At the maximum pace of 1,440 spins, a £5 player would stake £7,200 in an hour, with an average cost of £288 at 96% RTP. A £2 player at the same pace would stake £2,880, with an average cost of £115.20. These are long-run averages. In a single hour you could finish well ahead or lose far more, especially on high volatility slots, where the swings are larger.

How stake limits change a slot's max win in pounds

Slot max wins are quoted as a multiple of the stake, so the cap on stakes also caps the largest possible prize in pounds. A game with a 5,000x max win could pay up to £25,000 on a £5 spin, or £10,000 on a £2 spin. The odds of reaching that ceiling are tiny in either case; most players will never see it.

Progressive jackpots are different, because their prize is a pool rather than a multiple. Some jackpot games require a minimum stake or give a better chance at higher stakes, and under-25s may find those rules matter more. The mechanics are set out in how progressive jackpots work. The full maths of max wins is covered in slot max win explained.

Stake limits, bonus max bet rules and 10x wagering

Bonuses add a second limit on top of the legal one. Most deposit bonuses carry a max bet rule, and breaking it can void the bonus. Casumo's welcome bonus, for example, sets a maximum of £5 per bet while the bonus is active, which matches the legal cap for over-25s but is irrelevant for under-25s, who are already limited to £2.

Since 19 January 2026, wagering on any UK casino bonus is capped at 10 times. Here is how stake size changes the work involved. A £100 bonus with 10x wagering means £1,000 of slot stakes before the bonus converts. At £2 per spin that is 500 spins; at £5 it is 200 spins; at 50p it is 2,000 spins. Smaller stakes take longer but spread the risk across more spins. Our wagering examples page works through more cases.

What the online slot stake limits do not cover

The £5 and £2 limits are specific to online slot games. They do not set stakes for other online casino games such as roulette, blackjack or live dealer tables, which have their own maximums set by the operator. Land-based gaming machines in pubs, arcades, bingo halls, betting shops and casinos sit under separate machine category rules.

The limits also do not cap how much you can deposit or lose overall. That is the job of your own deposit limits and the casino's checks on spending, which we cover in the guide to affordability checks on slot sites.

Choosing a stake below the cap

The legal limit is a ceiling, not a recommendation. A stake that suits you depends on your budget, how long you want to play and how swingy the game is.

1. Decide how much you are prepared to spend on this session and treat it as the cost of entertainment.
2. Decide roughly how long you want to play, for example one hour.
3. Estimate spins: at a relaxed pace, around 400 to 600 spins an hour.
4. Divide your budget by the number of spins, then halve it if the slot is high volatility.
5. Set the game's total bet to that figure or the nearest lower option, and check the total shown by the spin button.
6. Set a deposit limit in your account so the session budget cannot quietly grow.

Bonuses that fit within the stake limits

Casumo offers new customers aged 18 or over a 50% bonus up to £100 on a first deposit of at least £20, with the bonus wagered 10x within 7 days and a £5 maximum bet while it is active. 10bet's casino welcome bonus is a 100% match up to £25 for new UK customers, wagered 10x on slots within 3 days, with bonus winnings capped at £1,000. Terms apply to both.
