Slotroyals is run by Onimim Ltd, which states that it holds an Anjouan licence. Its Welcome Bonus Pack gives up to £6,000 + 500 free spins over four deposits from £20, and weekend Slot Cashback of up to 10% carries no wagering. Our score: 8.4/10

Slotroyals suits slot players who are happy to enter a separate code with each deposit and who value cashback paid without wagering. The Welcome Bonus Pack spreads up to £6,000 and 500 free spins across four deposits of at least £20, and the weekend Slot Cashback returns up to 10% of net slot losses.
The catch is in the small print. Welcome wagering is 40x the bonus plus deposit, to be completed in just 10 days, with stakes capped at £5 or 5% of the bonus, whichever is lower. Each deposit has to be turned over 5 times before you withdraw, the terms allow a fee of up to 8% on multiple withdrawals within a rolling 30 days, and the account has no self-service deposit, loss or session limits.
Our score: 8.4/10, 15th of the 30 casinos in our full list.
What we could not confirm: withdrawal processing times, per-method minimums and maximums, and which footer payment brands the cashier shows, because it only opens after you log in.

Slotroyals fits you if you play mainly video slots, deposit £20 or more at a time and like promotions you can plan around: a code-based reload once a week and cashback every weekend.
Look elsewhere if you want to clear a bonus on live casino or blackjack (both count 0%), like to withdraw small amounts several times a month, or need limits you can set yourself in the account.
If you open a Slotroyals account through a link on this page, The Mountain Air may receive a commission. That payment has no influence on the 8.4 score or on where Slotroyals sits in our list, and the casino’s own terms decide what you actually get.
Each stage has its own code, entered with the deposit; the bonus is then credited straight away on top of it. If you forget the code, contact support before you place any bet. Each code can be claimed once per player, account, IP address or household.
| Deposit | Match | Max bonus | Free spins | Code |
|---|---|---|---|---|
| 1st | 400% | £2,000 | 200 on Starburst | WELCOME1 |
| 2nd | 250% | £2,000 | 150 on Gates of Olympus | WELCOME2 |
| 3rd | 150% | £1,000 | 100 on Big Bass Bonanza | WELCOME3 |
| 4th | 100% | £1,000 | 50 on The Dog House | WELCOME4 |
| Pack | 900% (advertised) | £6,000 | 500 | One code per stage |
Filling all four caps takes deposits of £500, £800, about £667 and £1,000, close to £2,970 in total. More realistically, a £20 first deposit with WELCOME1 brings an £80 bonus and 200 spins. Because wagering counts bonus plus deposit, you then need £4,000 of bets (40 x £100) within 10 days, at no more than £4 a spin, since 5% of £80 is lower than £5. The value of each free spin is not published.
| Term | What the terms say | What it means for you |
|---|---|---|
| Wagering | Bonus plus deposit 40 times within 10 days | A £50 deposit with a £200 bonus needs £10,000 of bets |
| Maximum bet | £5 or 5% of the bonus, whichever is lower | Small bonuses bring an even lower stake ceiling |
| Game weighting | Slots, scratch, classic and fun games 100%; roulette 10% (not live roulette); live casino, blackjack, video poker, craps, baccarat and multiplayer games 0% | Clear the bonus on slots |
| Restricted play | No bets with minimal or no risk, no slot gamble feature; cutting stakes by 75% or more after large bets can lead to deductions | Keep to steady, ordinary spins |
| Conversion limit | Welcome campaigns without their own conversion terms turn at most 10 times the bonus into real money | An £80 bonus can release no more than £800 |
| Cashing out | No withdrawal while a bonus is active; missing the deadline voids the bonus and its winnings | Finish the wagering or give up the bonus first |
| Free spins | Expire 7 days after crediting unless stated otherwise | Use them within the week |
Your real money is used first, winnings made while a bonus is active go to the bonus balance, and only one slot or live casino bonus can run at a time. If any of these clauses are new to you, our plain-English guide to wagering requirements walks through them one by one.
| Promotion | What you get | Minimum deposit | Wagering |
|---|---|---|---|
| Weekly Reload Bonus | 50% up to £250 with code WEEKLY250, once a week | £20 | Bonus plus deposit 25x within 10 days |
| Slot Cashback | Up to 10% of net slot losses, Friday 00:00 to Sunday 23:59 (GMT+1), from £5 to £1,000 | None stated | None |
| Refer a Friend | £5 for you; 10 free spins at £0.10 each for your friend | £20 (friend’s deposit) | None |
| Open Banking Special Offer | 50 extra free spins on a first-ever Open Banking (Instant Bank Transfer) deposit | First deposit | Not stated |
Cashback is credited on Monday and must be activated before it expires; live casino play does not count. Reload campaigns turn at most 5 times the bonus into real money.
The five-level VIP Club runs from Velvet and Royale to Imperial (priority support, 5% weekly cashback), Sovereign (10% weekly cashback, a dedicated VIP manager, fast-track withdrawals) and Eternal (15% weekly cashback and higher withdrawal limits). Level requirements are not published, and the general terms say VIP service is by invitation and can be discontinued at any time.
The slots lobby has its own Jackpots section, where we found King Kong Cash and Wish Upon a Cashpot, both from Blueprint. The operator does not publish how many jackpot games it carries or how their prize pools work, so check each game’s information screen for the jackpot type before you play. All slots count 100% towards wagering, but the maximum-bet rule still applies while a bonus is active. Our overview of jackpot slots and how they pay explains the main formats.
The operator does not publish a total. When we counted the lobby, it listed about 3,880 distinct titles, including 3,546 in the Slots section and 92 live tables. Sections include Megaways, Bonus Buy, Book Of, Jackpots, Casual (scratch cards, keno, bingo, plinko, mines and crash-style games) and Table Games.
| Category | Examples (studio) |
|---|---|
| Slots | Starburst, Gonzo’s Quest (NetEnt); Book of Dead, Reactoonz (Play’n GO); Gates of Olympus, Sweet Bonanza (Pragmatic Play); Immortal Romance (Microgaming); Le Bandit (Hacksaw Gaming); Pirots (ELK Studios); Fishin’ Frenzy Megaways (Blueprint) |
| Live casino | Gravity Roulette, VIP Baccarat (Iconic21); Blackjack Prestige (Lucky Streak); London Live Roulette, Andar Bahar (Ezugi) |
| Table games | European Roulette (Evoplay); Three Card Poker, Caribbean Stud (Habanero); 3D Baccarat (Iron Dog Studio) |
| Crash and instant | Speed Crash, Limbo, Plinko, Mines (Hacksaw Gaming) |
Live tables come from Ezugi, Iconic21 and Lucky Streak; Evolution and Red Tiger games, which some other review sites mention, were not in the lobby we checked.
The operator names these payment brands, all but Open Banking in the site footer; per-method limits and times are not published.
| Type | Brands shown by the operator |
|---|---|
| Cards | Visa, Mastercard |
| Mobile wallets | Apple Pay, Google Pay |
| E-wallets | Skrill, Neteller, MiFinity, ecoPayz, Payz, Jeton |
| Bank | Open Banking (Instant Bank Transfer), named in the first-deposit promotion |
The only published minimum is £20, for each welcome stage, the weekly reload and a referred friend’s deposit. Deposits must come from a card or account in your own name. In most cases the casino covers deposit transaction fees, while your own bank’s charges are yours, and a chargeback or reversed payment can bring a £50 administration fee.
The operator does not publish processing times, but the terms set out the order of steps:
Money goes back to the method you deposited with. Higher VIP levels bring priority processing, with fast-track withdrawals from Sovereign upwards.
| Limit or charge | What the terms say |
|---|---|
| Per 7 days | Up to £5,000, unless stated otherwise |
| Per 30 days | Up to £15,000, unless stated otherwise |
| Winnings per day | Capped at £100,000; any excess can be deducted within 30 days |
| Several withdrawals in 30 days | Fee of up to 8% of the amount withdrawn |
Limits can differ by VIP level.
Full verification is compulsory when you request a withdrawal of any amount, when lifetime deposits pass £5,000, or when a transaction looks suspicious. Expect to upload a signed government photo ID that does not expire within the next 3 months, a selfie holding it (plus a live selfie check), and a bank statement or utility bill from the last 3 months in the same name; proof of payment can also be requested. The privacy policy asks for requested documents within 72 hours. Only one account is allowed per person, household, email, payment account, IP address or shared computer, and linked accounts lose their bonuses and winnings.
According to its terms, Slotroyals is owned and operated by Onimim Ltd (Hamchako, Mutsamudu, Anjouan), which states that it holds Anjouan licence ALSI-192407051-FI3 under the Computer Gaming Licensing Act 007 of 2005. The Anjouan public licence register lists this as a valid B2C licence issued on 29 July 2024 and running until 28 July 2027, with slotroyals.com among its domains, and the validator behind the site’s licence seal shows the same. Onimim (CY) Ltd in Nicosia acts as a service facilitator in some jurisdictions and processes Paysafe-related payments.
Two details are worth knowing: the general terms print the licence number with a different ending (FB rather than FI3), and when we checked, slotroyals.com forwarded to a numbered mirror domain that the Anjouan validator did not show as valid. Disputes about a settled bet must be raised within 3 days; support aims to answer complaints within 28 days, and unresolved cases go to management and then to arbitration.
Slotroyals is a young brand, so public player feedback is still thin. One hands-on review elsewhere praises the clean layout and the cashback without wagering, while other reviews point to the missing self-service limits and one found verification slow.
Slotroyals runs in desktop and mobile browsers, and the account menu keeps bet history, transactions, bonuses with remaining wagering, and verification in one place.
You can reach the support team at any hour by live chat or by email at [email protected]; no phone number is listed. Written communication is in English, and the site is available in English, German, French, Greek, Czech and Hungarian. Sovereign and Eternal members get a personal VIP manager, and the top tiers extra channels including WhatsApp.
Pros
Cons
Choose Slotroyals Casino if you play slots with regular deposits of £20 or more, will use the codes in the right order and want weekend cashback you can withdraw without playing it through. Skip it if you want published payout times, prefer several small withdrawals a month, or rely on self-service limits to keep your play in check.
Compare also: all 30 casino reviews, our top 10 jackpot casinos, Kingia Casino review, Sankra Casino review and Spinobon Casino review.
Play at Slotroyals only if you are 18+. Gambling here is entertainment and never a way to make money, so fix a budget and a time limit before you play and stick to both. Because the account has no self-service limits or reality checks, keep your own record of what you deposit.
The operator’s tools run through support: a 7-day cooling-off period or self-exclusion (the Responsible Gaming page gives a minimum of 3 months, while the general terms allow periods from 24 hours). To self-exclude, email [email protected] with a clear request and the period you want; the terms say this is actioned within ten business days, so if you want a break sooner, ask support for the 7-day cooling-off as well. You can also close the account by email or use the self-assessment checklist on the Responsible Gaming page. More practical ideas are in our guide to safer gambling.
If Slotroyals stops feeling like fun, or you are concerned about someone else’s play, call the National Gambling Helpline (GamCare): free and confidential, 24/7, 0808 8020 133. Further support comes from Gamblers Anonymous, GamAnon (for family and friends), Gordon Moody and the NHS gambling clinics.
The Welcome Bonus Pack gives up to £6,000 + 500 free spins over four deposits: 400% up to £2,000 + 200 spins (WELCOME1), 250% up to £2,000 + 150 spins (WELCOME2), 150% up to £1,000 + 100 spins (WELCOME3) and 100% up to £1,000 + 50 spins (WELCOME4). The minimum deposit for every stage is £20.
You have 10 days to wager the bonus and deposit together 40 times, and no single bet may exceed £5 or 5% of the bonus, whichever is lower. Slots count in full, while live casino games and blackjack do not count at all.
£20 for each welcome stage, the Weekly Reload Bonus and a referred friend’s deposit. The operator does not publish a general cashier minimum or per-method minimums.
Processing times are not published. The terms cap withdrawals at £5,000 in any 7 days and £15,000 in any 30 days, ask for each deposit to be turned over 5 times first, and allow a fee of up to 8% if you withdraw several times within 30 days.
According to the operator, Onimim Ltd holds Anjouan licence ALSI-192407051-FI3. The Anjouan public register lists it as a valid B2C licence running until 28 July 2027.
