Session limit: meaning in casino apps
A session limit is a cap on how long one gambling session can run, set by you in a casino app's account tools. When the time is up, the app ends or pauses your play rather than just reminding you. It controls time, where deposit and loss limits control money.

Session limit meaning
You pick a length, such as 30 minutes or an hour, and the clock starts when you begin playing. When it runs out, the session stops. What happens next varies by operator. It may mean being logged out or having new bets blocked for a while, so check the app's help pages for its exact behaviour.
It's a time tool, which makes it different from the money tools elsewhere in our casino app glossary, such as the deposit limit and loss limit.
Session limits, reality checks and time-outs compared
Three time tools are easy to mix up. The difference is whether they remind you, stop you, or lock you out for longer.
| Tool | What it does | Length | Required by UK rules? |
|---|---|---|---|
| Session limit | Ends the session at a time you choose | You choose | Offered by some operators |
| Reality check | Shows time elapsed; you must acknowledge it | You set how often | Yes (RTS 13B) |
| Time-out | Locks the account for a period | 24 hours up to 6 weeks | Yes (LCCP 3.3.4) |

Why session length matters: an hour in pounds
Time and money are linked through the pace of play. UK slots must allow at least 2.5 seconds per spin, which sets a ceiling of 1,440 spins an hour (3,600 seconds ÷ 2.5). Most people play slower. The table below assumes one spin every 6 seconds, or 600 spins an hour, on a slot with a 96% RTP (a 4% house edge).
| Stake per spin | Staked in an hour | Expected loss in an hour |
|---|---|---|
| 10p | £60 | £2.40 |
| 50p | £300 | £12 |
| £1 | £600 | £24 |
Expected loss is stake multiplied by house edge, and actual results swing well above or below it. Halving session length roughly halves the amount staked, and that is the real point of capping time. See house edge for the maths.
UK rules that support session limits
The Commission's RTS 13 on time requirements and reality checks (opens in a new tab) says you must be able to choose how often a reality check appears, and must acknowledge it to clear it. Full-screen apps that hide the phone's clock must show the time of day or elapsed time instead. Elapsed session time must be displayed too.
From 17 January 2025 those display rules reached all online casino games, with net spend and time shown in real time, as the Commission's 2025 game rules announcement (opens in a new tab) explained. Setting your own time cap goes one step further by acting on that clock. Our guide to reality checks in casino apps covers the reminder side.
Adding a session limit at phone level
If your casino app has no session limit, your phone can supply one. Google's Digital Wellbeing help page (opens in a new tab) says that when an app timer runs out, the app closes and its icon dims, and timers reset at midnight.
- Open Digital Wellbeing on your Android phone.
- Find the casino app in the list of apps.
- Tap Set timer next to it and choose a daily allowance.
- Confirm, and the app closes once the allowance is used.
Because the timer is daily, it works as a daily session cap rather than a per-session one. Our guides to blocking casino apps with Digital Wellbeing and blocking gambling apps on iPhone cover both platforms, and phone habits and gambling looks at the bigger picture.

Frequently asked questions
What is a session limit on a casino app?
It's a time cap you set on a single gambling session. When the time runs out, the app ends or pauses play instead of just showing a reminder. It's different from money tools such as a deposit limit, which caps what you pay in. Not every operator offers one, so look in the app's limits or safer gambling area before relying on it.
Is a session limit the same as a reality check?
No. A reality check tells you how long you've been playing and asks you to acknowledge it, but you can carry on afterwards. A session limit stops the session when the time is up. UK rules require reality checks with a frequency you choose, while session limits depend on the operator. Our reality check guide explains the reminder in detail.
Do UK casino apps have to offer session limits?
Not as such. The Commission's rules require reality checks, a visible session clock and, for online casino games since January 2025, net spend and time shown in real time. Operators must also offer time-outs. Many apps add session limits on top, but check before you sign up. Our overview of safer gambling tools in casino apps lists the common options.
How long should a casino app session be?
There's no official figure; pick a length that fits a budget you've already set. A useful check is the arithmetic: at 600 spins an hour and 50p a spin, you'd stake £300 in an hour with an expected loss of £12 on a 96% RTP slot. Shorter sessions mean less staked. Budgeting for casino apps helps you choose a figure.
Can I set a session limit on my phone instead of in the app?
Yes, on Android you can. Digital Wellbeing lets you set a daily timer for any app; when it runs out, the app closes and its icon dims until midnight. That works alongside any limit inside the casino app. Our guide to blocking casino apps with Digital Wellbeing shows the steps.
What happens when a session limit runs out?
It depends on the operator, so read the app's help pages before you set one. It may mean being logged out or having new bets paused for a while. Either way, the aim is the same: to turn a time plan into a firm stop rather than a reminder you can tap away. If you want a longer break than one session, a time-out locks the account for 24 hours or more.
