Game speed rules on mobile casino games set a floor on how fast you can play in the UK: at least 2.5 seconds per slot game cycle, and at least 5 seconds for other casino games such as roulette and blackjack. They apply in every licensed app. This guide explains how the timing is measured, what it means for live speed games, and what pace does to the cost of an hour's play.
Online slots: at least 2.5 seconds per game cycle since 31 October 2021.
Other casino games: at least 5 seconds per game cycle since 17 January 2025.
Timing runs from the start of one game to the start of the next.
Faster play means more stakes per hour, so a higher expected cost.

Game speed rules on mobile casino games: the minimum times
The UK's speed rules are part of the Gambling Commission's Remote Gambling and Software Technical Standards. They don't care what device you use, so a phone app, a tablet and a desktop browser all have the same floor. Here's the full set.

Roulette, blackjack, baccarat and other casino games (RNG and live)
The clock runs from the moment a game starts until the next game cycle can begin. It's not a rule about how long the reels must spin or the ball must roll. A slot can show its result quickly; it just can't let the next spin begin until 2.5 seconds have passed since the last one started.
For slots there's a second condition: you have to release the spin button and press it again. Holding it down won't fire off spins at the minimum interval. That's part of why autoplay disappeared, which we explain in why there is no autoplay on UK casino apps.
Start to start, not start to finish. A table game might settle in under 5 seconds; the next round still can't start until 5 seconds after the last began.
Bonus rounds are treated differently. The Commission's RTS 14 guidance exempts bonus games that need no extra stake from the time-to-result requirement.
The rule is a minimum. Most live games run far slower than 5 seconds because of dealing, spinning and betting time.
Why game speed matters: the cost of an hour on your phone
Speed matters because the house edge is charged on every stake. More rounds per hour means more money staked, and a higher expected loss, at the same bet size. The minimums put a ceiling on that pace.

Real sessions rarely run at the theoretical maximum, but the pattern holds: the faster the game, the more an hour costs at the same stake. The house edge figures come from standard game maths, such as Wizard of Odds' house edge table (opens in a new tab). Our house edge by game page lists the main mobile games side by side.
Expected loss is a long-run average. Individual sessions vary, and losing is the more likely outcome over time on every game in the table.
Speed roulette, speed baccarat and other fast live games
Some live games are marketed as 'speed' versions. They're faster than the standard tables but still far slower than the 5-second floor, so they sit comfortably within UK rules.
No turbo, no slam stop, no playing two games at once
The minimum times would mean little if you could skip the animation or run several games side by side, so the standards close those gaps too.
RTS 14E: a slot must not let you reduce the time until the result is shown. Turbo, quick spin and slam stop features aren't permitted. See our glossary entry on turbo spin.
RTS 14C: no functionality to play several games at the same time. That covered slots from 2021 and was extended to casino games in 2025, so a UK app can't split your screen across two tables.
RTS 14F: a game must not celebrate a return equal to or less than your stake, which removes the 'win' fanfare from what's really a loss.
Clocks, session timers and reality checks on a phone
Speed rules work alongside time rules in RTS 13. One is especially relevant on mobile: if a full-screen app hides your phone's clock, it must show the time of day or the time elapsed itself. Since 17 January 2025, casino games must also show your net spend and time spent in real time, as slots already did.
The case is a reminder that the rules bind game studios as well as casino operators. If a game in an app seems to let you start spins faster than the minimum, you can raise it with the operator and, if needed, through its complaints process. Our complaints guide covers the steps.

Frequently asked questions
How fast can a slot spin in a UK casino app?
No faster than one game cycle every 2.5 seconds. RTS 14D sets that minimum from the start of one slot game to the start of the next, and you must release and press the spin button again each time. The rule has applied since 31 October 2021, in apps and on websites alike. Our slot stake limits guide covers the other big slot rule.
What is the 5-second rule for casino games?
Since 17 January 2025, casino games other than slots must allow at least 5 seconds from the start of one game cycle to the start of the next. It covers RNG and live roulette, blackjack, baccarat and house-played poker, but not peer-to-peer poker or bingo. Most live tables run much slower anyway. See our game speed rules page for the wording.
Do speed roulette games break the 5-second rule?
No. Evolution's Speed Roulette rounds take about 25 seconds, roughly half a standard round, and Pragmatic Play's version averages around 25 seconds. That's five times the 5-second minimum. The speed comes from shorter betting windows and quicker spins, not from skipping the rules. Our live roulette on mobile guide covers the standard tables.
Why does my slot pause between spins?
Because UK rules require at least 2.5 seconds from the start of one spin to the start of the next. If a result shows quickly, the game still waits until that time has passed before the next spin can begin. Turbo and slam-stop buttons, which used to cut that time, aren't allowed. Our answer on why slots spin slower on UK apps explains more.
Do the speed rules apply to bonus rounds?
Not in the same way. The Commission's RTS 14 guidance exempts bonus or feature games that need no extra stake from the time-to-result requirement, so free spins inside a feature may play out differently from paid spins. The 2.5-second rule still governs the paid base-game spins that lead into them. Our free spins in casino apps guide covers spin offers.
Can I play two casino games at once on my phone?
Not within a UK-licensed app. RTS 14C bans functionality that lets you play several games at the same time, which covered slots from 2021 and was extended to other casino games in January 2025. That means no split-screen tables or multi-slot views. Our guide to managing several casino apps looks at the wider habit of juggling apps.
Has anyone been fined for breaking the speed rules?
Yes. In June 2026 the Gambling Commission announced that Stakelogic BV, a games supplier, would pay £122,835 after some of its slots ran below the 2.5-second minimum. The case shows the rule applies to game studios as well as casino operators. Our online game design rules page lists the other standards that came in at the same time.
Does a faster game cost more?
At the same stake, yes, because you place more bets per hour and the house edge applies to each one. A slot at the 2.5-second minimum could take 1,440 £1 spins an hour, an expected loss of £57.60 at 96% RTP, while live roulette at about 50 seconds a round costs around £1.94 an hour at £1.
