Checked against the UK Gambling Commission public register on 9 November 2026. An independent site, not the Gambling Commission. How we work.

UK online slot stake limits are a legal cap on how much a player can stake on a single game cycle of an online slot. For players aged 25 and over the cap is £5. For players aged 18 to 24 it is £2. The limits are a condition on remote casino operating licences, so every UKGC licensed casino has to apply them. This page sets out what the rule says, when it started and how the Commission explains it.

The dates

The Gambling Commission's guidance gives two start dates. The £5 limit for all adults went live on 9 April 2025. The £2 limit for adults aged 18 to 24 went live on 21 May 2025. From that second date the age-based structure was in full effect.

The limits were made through a statutory instrument that adds a new condition to every remote casino operating licence, including licences issued before the instrument came into force. For licences already in place, the condition took effect from the date the rules came into force.

What the condition says

The wording is short. For an online slots game, the total amount that an individual may stake in relation to any game cycle may not exceed £2 where the individual is under 25 years old, and £5 where the individual is 25 years old or over. Everything else in the guidance explains how to apply those two numbers.

The legal definitions matter:

  • Online slots game: a casino game built on reels or a similar display of moving or changing images or text, where the result shown decides whether the player wins a prize or another advantage.
  • Stake: paying or risking an amount in connection with an online slots game.
  • Game cycle: the period from the moment a player starts a game until all the money staked has been lost, or all winnings have been paid or made available for collection.

What is not covered

The Commission states that the limits apply to online slots only. They do not apply to other casino games, such as roulette or blackjack. A casino therefore applies the cap to the slots section and not to table games, live dealer games or sports betting. Whether a particular game meets the slots definition is a matter for the operator and the Commission, not for the player.

Separately, the Commission refers to its remote gambling and software technical standards, which require at least 2.5 seconds between starting a slot game and starting the next game cycle (RTS 14D). The two rules are different, but both aim at slowing the pace of slot play.

Worked examples from the guidance

The Commission's guidance includes examples that make the cap concrete.

  1. A customer aged 27 stakes £5 on a slot. No further staking can be provided until the cycle ends, because £5 is the maximum for someone aged 25 or over.
  2. A customer aged 27 stakes £2. More staking opportunities could be provided within the same cycle up to a further £3, for a total of £5.
  3. A customer aged 19 stakes £2. No further staking can be provided until the cycle has ended, because £2 is the maximum for ages 18 to 24.
  4. A customer aged 27 stakes £5 and wins a prize that they can accept, or reject for a chance at a larger one. The customer is not asked to put in more money, so the gamble does not breach the cap. If the gamble fails, the balance has already been reduced by the £5 stake and stays unchanged afterwards.

The point of the examples is that the cap is per cycle, not per day or per session.

What the limits mean for you

On a UKGC licensed site, the limits apply whichever brand you use, because they are a condition of the licence. You can check a brand's licence on the register: see how to check a UKGC licence. The licensed casinos section lists the brands we have matched to a licence holder.

The limits sit with other rules for licensed sites: affordability checks, bonus rules and GAMSTOP, explained on the GAMSTOP page. None of them replaces the others.

Outside the rules

A casino that holds no UKGC licence is not bound by the condition. People who search for slots without a stake cap are looking for that gap. Playing at such a site is not an offence for the player, since the Gambling Act 2005 section 33 offence is committed by the operator. Still, a UK player there is not covered by the stake limits, GAMSTOP or the UKGC complaint route and ADR, and the affordability checks are not required either. Our page on slots not on GAMSTOP describes that side as information only.

Questions readers ask

Do the stake limits apply to roulette and blackjack?

No. The Gambling Commission's guidance states that the limits are for online slots only and do not apply to other casino games such as roulette or blackjack. A game must meet the legal definition of an online slots game, which is built around reels or similar moving images and a prize shown by the result.

How is the age that sets the limit decided?

The legal wording uses the player's age. Under the condition, the total staked in a game cycle may not exceed £2 if the person is under 25 and £5 if the person is 25 or over. Operators work from the age they hold for the account, which is why accurate details matter.

Is there a minimum time between spins?

Yes. The Commission's guidance refers to its technical standards, RTS 14D, which require at least 2.5 seconds from the time a slot game starts until the next game cycle can begin. That applies to remote slots and sits alongside the stake limits.

Does a casino outside the UK have to follow the limits?

The condition is attached to remote casino operating licences issued in Great Britain. A site with no UKGC licence is not bound by it, so a UK player there has no stake cap from the Commission and no UK route to complain about it.

What counts as a game cycle?

A game cycle starts when the player begins a game and ends when all the money staked has been lost, or all winnings have been paid or made available to collect. A game can contain several cycles. Extra stakes can be taken inside one cycle only up to the cap.
