The Review RoomUK online slot stake limits: £5 a spin, or £2 if you are under 25
If you play online slots at a GB-licensed casino, the most you can stake on a single spin is £5 if you are 25 or over, and £2 if you are 18 to 24. The £5 limit started on 9 April 2025 and the £2 limit on 21 May 2025.[1] The limits apply to online slots only, not to table games such as roulette or blackjack.
The limits at a glance
| Your age | Maximum stake per spin | In force since |
|---|---|---|
| 18 to 24 | £2 | 21 May 2025 |
| 25 and over | £5 | 9 April 2025 |
The Commission's guidance sets the limit "per game cycle", which in plain terms means one spin, including any feature that the spin triggers.[1] Remote slots must also leave at least 2.5 seconds between one game cycle and the next.[1]
Which games are covered
The limit applies to online slot games offered under a remote casino licence. The Commission's guidance says it does not cover games such as roulette or blackjack.[1] So you may find a table game at the same casino that accepts a £10 or £50 stake. That is not a breach of the rules, and it is worth knowing if you set your own budget around the slot limit.
How the casino knows your age
Every online gambling business must verify your age and identity before you can gamble.[2] That verified date of birth is what decides whether the £2 or £5 limit applies to your account. When you turn 25, the higher limit applies under the rules. You do not need to do anything to qualify.
What the limit does not do
A per-spin cap is not a spending cap. At £5 a spin with a spin every 2.5 seconds, the stakes on a single slot can add up fast: 100 spins is £500 staked, even though most of it is paid back as wins along the way. What you actually lose depends on the game's return, the swings of a session and how long you keep playing. The stake limit slows that down. It does not stop it.
That is why the deposit limits and time reminders in your account settings matter more than the stake cap. Our page on safer gambling tools for UK players explains where to find them and how GAMSTOP blocks every GB-licensed site at once.
A stake above £5 is a warning sign
If an online casino lets you spin a slot for more than £5, or more than £2 when you are under 25, it is either breaking its licence conditions or does not hold a GB licence. Either way, stop and check the site against the register before you deposit again. Our step-by-step licence check shows how.
Bonus terms can set a lower maximum stake than the legal cap while a bonus is active, but never a higher one. The other bonus rules that changed in 2026 are covered in our guide to the 10x wagering cap on UK casino bonuses.
