This guide is written for UK players who use SlimKing or are thinking about it. It sets out the tools available on your account, the legal protections that apply to every UK-licensed casino, the signs that gambling may be becoming a problem and the organisations that offer free help. If you need to talk to someone now, call the National Gambling Helpline on 0808 8020 133. It is free, confidential and open 24 hours a day.

Basic principles

  • Only gamble with money you can afford to lose. Treat it as the cost of entertainment, not an investment.
  • Gambling is not a way to make money, pay bills or clear debts.
  • Set a budget and a time limit before you start, and stop when you reach either.
  • Do not chase losses by depositing more to win back what you have lost.
  • Avoid gambling when you are stressed, upset, unwell or have been drinking.
  • Take regular breaks and balance gambling with other activities.

Safer-gambling tools at SlimKing

UK-licensed operators must provide tools that let you control your gambling. SlimKing offers the following from your account settings.

ToolWhat it doesDetails
Deposit limitsCaps how much you can depositDaily, weekly or monthly; can be set at registration
Loss limitsCaps your net losses over a periodDaily, weekly or monthly
Reality checksShows an on-screen reminder of how long you have been playingYou choose the interval
Time-outBlocks access to your account for a short period24 hours to 6 weeks
Self-exclusionCloses access to your account for a long period6 months to 5 years
GAMSTOPExcludes you from all UK-licensed online gambling sites6 months, 1 year or 5 years

Deposit and loss limits

You can set a deposit limit during registration, which takes about two minutes. You can change it at any time afterwards. A decrease applies straight away; an increase only applies after a cooling-off period. A loss limit works in the same way but is based on how much you lose rather than how much you deposit.

Reality checks

A reality check displays a pop-up after a set interval showing how long your session has lasted and how much you have won or lost. Use it to decide whether to continue or stop.

Time-out

A time-out lets you take a break of between 24 hours and 6 weeks. Your account is locked for the chosen period and reopens automatically afterwards. You cannot cancel a time-out once it has started.

Self-exclusion

Self-exclusion is for anyone who feels they need a longer break. You can choose a period of between 6 months and 5 years. During this time you cannot log in or deposit, and SlimKing must stop sending you marketing. The exclusion cannot be lifted early. When it ends, your account does not reopen automatically; you would need to contact support to discuss returning. To set one up, use your account settings or contact SlimKing support.

GAMSTOP

GAMSTOP is the free national self-exclusion scheme for online gambling in Great Britain. All UK-licensed operators, including SlimKing, must take part. One registration at gamstop.co.uk blocks you from every participating site for 6 months, 1 year or 5 years. It is a good option if you hold, or might open, accounts with several operators.

UK rules that protect you

These rules apply at SlimKing and at every casino licensed in Great Britain:

  • You must be 18 or over. Your age and identity are checked before you can deposit or play; see our verification guide.
  • Online slot stakes are limited to £5 per spin, or £2 per spin if you are aged 18 to 24.
  • Slots have no autoplay, no turbo or quick-spin features, and each spin lasts at least 2.5 seconds.
  • Bonus wagering requirements are capped at 10 times the bonus amount. See our wagering guide.
  • Credit cards and cryptocurrency cannot be used to gamble.
  • Operators must carry out affordability and wellbeing checks, and may ask for evidence of income if your spending rises.

Warning signs

Gambling may be becoming a problem if you recognise any of the following:

  • spending more money or time on gambling than you intended;
  • needing to bet larger amounts to get the same feeling;
  • trying to win back money you have lost;
  • borrowing money, selling possessions or missing bills to gamble;
  • feeling restless, irritable or anxious when trying to cut down;
  • hiding or lying about your gambling to family or friends;
  • gambling affecting your work, studies, sleep or relationships;
  • feeling guilty or low after gambling.

If any of these apply, consider setting a limit, taking a time-out or self-excluding, and speak to one of the organisations listed below.

Take the self-assessment

Thinking about the last 12 months, answer each question honestly. Your answers stay on this device.

Question 1

1. Have you bet more than you could really afford to lose?

Question 2

2. Have you needed to gamble with larger amounts of money to get the same feeling of excitement?

Question 3

3. When you gambled, did you go back another day to try to win back the money you lost?

Question 4

4. Have you borrowed money or sold anything to get money to gamble?

Question 5

5. Have you felt that you might have a problem with gambling?

Question 6

6. Has gambling caused you any health problems, including stress or anxiety?

Question 7

7. Have people criticised your betting or told you that you had a gambling problem, regardless of whether or not you thought it was true?

Question 8

8. Has your gambling caused any financial problems for you or your household?

Question 9

9. Have you felt guilty about the way you gamble or what happens when you gamble?

This self-assessment is based on the nine questions of the Problem Gambling Severity Index (PGSI), a widely used screening tool. Your answers stay in your browser. The result is an indication only and is not a diagnosis. If it raises concerns, contact the National Gambling Helpline on 0808 8020 133.

Advice for family and friends

Gambling problems often affect the people around the player as much as the player. If you are worried about someone:

  • Choose a calm moment to talk, and focus on how their gambling affects you rather than blaming them.
  • Avoid lending money or paying off their gambling debts, as this can allow the problem to continue.
  • Protect your own finances, for example by keeping separate accounts.
  • Encourage them to use limits, self-exclusion or GAMSTOP, and to contact the National Gambling Helpline.
  • Look after yourself. GamCare offers support to family members and friends as well as to gamblers, on the same number: 0808 8020 133.

Blocking software and bank controls

Blocking tools add a practical barrier that can help when self-control is difficult.

  • Gamban blocks access to gambling websites and apps on phones, tablets and computers. Details are at gamban.com.
  • Bank gambling blocks. Many UK banks let you block gambling transactions on your debit card through their app. Check your bank’s app or ask your bank.
  • Device controls. Parental controls and content filters on phones and home broadband can also restrict access to gambling sites.

Using a blocking tool together with GAMSTOP and self-exclusion at SlimKing gives the strongest protection.

Questions players ask

How do I set a deposit limit at SlimKing?

+
You can set a daily, weekly or monthly deposit limit during registration, or later from the safer-gambling section of your SlimKing account. Decreases take effect immediately. Increases are subject to a cooling-off period before they apply, which gives you time to reconsider. If you are unsure what limit to choose, base it on the amount you can afford to lose after essential bills.

What is the difference between a time-out and self-exclusion at SlimKing?

+
A time-out is a short break from 24 hours to 6 weeks; your account reopens automatically when it ends. Self-exclusion is for a longer period, from 6 months to 5 years, and is meant for anyone who feels they have lost control. During self-exclusion you cannot log in, deposit or receive marketing, and the exclusion cannot be reversed early.

Does GAMSTOP cover SlimKing?

+
Yes. SlimKing operates under a Great Britain gambling licence, and all such operators must take part in GAMSTOP. Registering at gamstop.co.uk excludes you from every participating online gambling site in Great Britain for 6 months, 1 year or 5 years. If your details match a GAMSTOP registration, SlimKing must block you from opening or using an account.

Is the SlimKing self-assessment a diagnosis?

+
No. The self-assessment on this page is based on the nine questions of the Problem Gambling Severity Index (PGSI), a widely used screening tool. It gives an indication of how gambling may be affecting you, but it is not a medical or clinical diagnosis. If your result concerns you, call the National Gambling Helpline on 0808 8020 133, free and available 24 hours a day.

What are the stake limits for online slots in the UK?

+
Online slot stakes in Great Britain are limited to £5 per spin, and £2 per spin for players aged 18 to 24. Slots also have no autoplay, no turbo or quick-spin, and each spin must last at least 2.5 seconds. These rules apply at SlimKing and at every other UK-licensed casino.
