Play the same slot in two regions and the British version may stand out: no autoplay, no turbo switch, and a short wait before each new spin can start. Those differences usually trace back to one source, the Gambling Commission’s remote gambling and software technical standards, or RTS. This piece explains what the standards require now, how they began with slots in 2021 and how they were widened in 2025, drawing only on the Commission’s own publications.
The current requirements, rule by rule
The game design rules now sit in RTS 14, titled “Responsible product design”. The Commission last updated its RTS 14 page on 12 January 2026. The sections that shape how a game behaves are:
| Section | What it requires |
|---|---|
| RTS 14C | No casino system may let a player run several games at the same time, whether through split screens, multiple screens or combined play. |
| RTS 14D | A slot must leave at least 2.5 seconds between the start of one game cycle and the start of the next. Each cycle needs the start button released and pressed again; holding it down cannot produce repeated spins. |
| RTS 14E | A casino game may not offer a way to bring the result forward. The standard names slam stop, quick spin and turbo as not allowed. Exempt: feature or bonus games that take no extra stake, and reveal-all or scratch-all options. |
| RTS 14F | A return equal to or below the total stake must not be celebrated. The game may display the amount and play a short result sound, but nothing styled as a win. |
| RTS 14G | Casino games other than slots must leave at least 5 seconds between game cycles. |
Above these sits a general rule, RTS 14A, covering all gambling products. They must not push customers to chase losses, increase their stake or carry on once they have indicated they want to stop.
Where it started: the 2021 slots package
The Commission announced a set of changes for online slots on 2 February 2021, to be in place by 31 October 2021. Its reasoning was that online slots produced the highest average losses per player of any gambling product, and that the features being targeted were associated with binge play, more intense play and players losing control.
Four areas were covered:
- Pace. Spins quicker than 2.5 seconds were prohibited, together with features that accelerate play or create an illusion of control over the result.
- Automatic play. Autoplay was withdrawn, with the Commission pointing to evidence that it helped players lose track of their play.
- Disguised losses. Audio or visuals implying a win when the return was equal to or lower than the stake were banned.
- Session data. Players needed to see how long they had been playing and their running total of wins or losses.
17 January 2025: the same limits for other casino games
On 1 May 2024 the Commission announced a group of changes, each with its own start date. The remote game design change came into effect on 17 January 2025 and carried the slot restrictions over to other online casino products. It banned turbo and slam stops, autoplay, operator-led features for running several products at once, and celebrating any return at or below the stake. The same change set the RTS 14G five-second gap for games other than slots, and required net spend and session length to be displayed in real time.
The display rules are spelled out in the Commission’s consultation papers. Net position is winnings less losses, counted from the start of the session. Time played must be on screen for the whole session, in hours, minutes and seconds.
Stake caps in April and May 2025
In a separate measure, the government capped how much can be staked on a single online slot game cycle. Two levels apply, per the Commission’s guidance: one for all adults from 9 April 2025, and a lower one for players aged 18 to 24 from 21 May 2025. The exact amounts are in that guidance.
Relevance to a virtual-coin site
SlotSpecs runs entirely on virtual coins, so these rules do not apply to play here in the same way. They are still worth knowing. They account for rules screens that differ between regions, and why a feature mentioned in one of our reviews, such as autoplay on Plinko+, might not appear in the British build of that game.
They also line up with the way we describe results. The ban on celebrating returns at or below the stake reflects the same principle we apply: results are expressed as multiples of the stake, and getting back less than you staked is not a win. When you load Fishin Frenzy, Golden Winner or Lucky Pharaoh on SlotSpecs, the version is free; the rules above govern how stake-based versions of such games must behave in Britain.
For the underlying loop these rules are meant to slow down, read how slots work. Practical limits are listed in playing responsibly.
