These terms set out the rules for playing at SlimKing, the online casino operated by SlimKing Entertainment Ltd. We operate under a gaming licence for Great Britain and are licensed and regulated for UK players only. By opening an account you agree to follow these rules, so please read them carefully. This page is a plain-English summary. The full terms and conditions shown in your account area are the binding version and prevail over this summary if the two ever differ.
1. Who can play
You must be at least 18 years old and a resident of the United Kingdom to register. We verify your age and identity before you can deposit or play any game, including free-to-play demos. We may ask for photo ID, proof of address or proof of payment ownership at any point, and we may also run electronic checks through independent verification agencies. You may hold only one account, and it must be registered in your own name with accurate details. If you have self-excluded through GAMSTOP, you will not be able to open or use a SlimKing account during your exclusion period.
2. Your account
You are responsible for keeping your login details private and for all activity on your account. Tell us straight away through live chat if you think someone else has accessed it. Accounts are personal and cannot be sold, transferred or shared. All balances are held and displayed in pounds sterling (£). We may suspend or close an account where we reasonably suspect fraud, duplicate accounts, underage play or a breach of these terms, and we will always return any genuine balance where the law allows us to.
3. Deposits
We accept Visa Debit, Mastercard Debit, PayPal, Skrill, Neteller, Paysafecard (deposits only), Revolut, Apple Pay, Google Pay, Trustly, Rapid Transfer and bank transfer. Credit cards are not accepted, in line with UK rules, and cryptocurrency deposits are not permitted on UK accounts. The minimum deposit is £10, or £20 if you want to claim the welcome offer. We do not charge fees on deposits. Every payment method must be registered in your own name.
4. Withdrawals
The minimum withdrawal is £10 and we charge no fees. Once a withdrawal is approved, e-wallet payments typically arrive within 2 hours, while debit card and bank transfer payments usually take 1 to 3 working days. Withdrawals are paid back to the method you used to deposit wherever possible. We may need to complete verification checks before releasing funds, and pending withdrawals will not be delayed to encourage further play.
5. Bonus terms
All bonuses are optional and you can decline or cancel them at any time. Wagering on every SlimKing bonus is capped at 10x, which is the UK maximum.
- Welcome offer: 200% up to £3,000 plus 200 free spins on your first deposit of £20 or more. The bonus carries 10x wagering on the bonus amount and must be completed within 30 days. Free spins are worth £0.10 each and are credited 20 per day for 10 days. Free-spin winnings carry 10x wagering.
- Corner Boost: every Friday you can claim 25% up to £100 when you deposit with PayPal, Skrill, Neteller or Revolut. Corner Boost has 10x wagering and is valid for 7 days.
- Weekly cashback: 10% up to £500 of your net losses, paid every Monday as cash with no wagering attached.
Only one welcome offer is available per person, household, payment method and device. Specific game contributions and any excluded games are listed in the full bonus terms in your account area.
6. Stake limits and game rules
UK rules apply to every online slot in our lobby. The maximum stake is £5 per spin, or £2 per spin for players aged 18 to 24. Bonus buy and feature buy options are not available, and autoplay is switched off. Table, live casino and game show limits vary by game and are shown at each table before you play. If a game malfunctions, all affected plays and payouts are void.
7. Prohibited conduct
You must not use SlimKing for any unlawful purpose. In particular, you must not:
- open more than one account or play on someone else’s account;
- use bots, scripts or any software that gives an unfair advantage;
- collude with other players or exploit errors in games or software;
- deposit funds that are not your own or that come from criminal activity;
- abuse bonuses through irregular betting patterns or linked accounts.
Where we find a breach, we may void affected winnings, withdraw bonuses and close the account. We also report suspicious activity to the relevant authorities as required by anti-money laundering law.
8. Safer gambling
Gambling should stay fun. You can set deposit limits, reality checks, time-outs and self-exclusion from your account area at any time. Decreases to limits take effect immediately, while increases have a cooling-off period. We take part in GAMSTOP, and we work with GambleAware, GamCare and Gordon Moody to point players towards free, confidential help. If we notice signs of harm, we may contact you, apply limits or pause your account.
9. Complaints
If something goes wrong, contact our support team through 24/7 live chat or the contact form in your account area. We aim to resolve complaints quickly and will give you a final response within the period set by our licence conditions. If you are unhappy with our final response, you can refer your complaint to the independent alternative dispute resolution (ADR) provider named in the full terms, free of charge.
10. Changes to these terms
We may update these terms to reflect changes in law, regulation or our services. We will tell you about material changes before they take effect, usually by a notice when you log in, and you can close your account if you do not accept them. The version in your account area always reflects the current rules, and it prevails over this summary.
