Important licensing note
Silver Oak Casino has no Gambling Commission licence and lists the UK among the countries it won’t accept, so British players would get no GAMSTOP and no UK regulatory help. In short, players in Britain shouldn’t play at Silver Oak or any of its sister sites.

The Silver Oak Casino sister sites
Every Primrose Media casino runs the same set of slots and games under the same owner, so the five Silver Oak Casino sister sites below are the ones whose offers, payout promises and paperwork differ most from Silver Oak Casino’s.
Raging Bull Slots
- The green one: Raging Bull Slots is green and black, with a horned gold logo and a homepage full of cartoon drummers promoting its Mighty Drums slot.
- Lighter wagering: Its welcome package offers up to 250% and £2,500, plus 50 free spins on Mighty Drums, and requires 10x wagering on slots and keno (40x on crypto deposits) with no winnings cap, while Silver Oak Casino’s general terms set 40x for slots.
- An owner in the footer: Its footer names Primrose Media Limited and quotes an Anjouan licence number, while Silver Oak Casino remains anonymous.
- Cover for bad weeks: Its menu includes Weekly Insurance and Monthly Insurance promotions, along with an Appreciation Free Chip and a Sign Up Free Chip.
- Phone support: Its homepage promises customer support via live chat and phone, 24 hours a day.
- Best for: Slots players who want a Silver Oak Casino sister site with far lighter wagering on their welcome bonus.
Slots of Vegas
- The Vegas one: Slots of Vegas’s homepage is dark purple, with cartoon showgirls, a witch and a masked robber much like Silver Oak Casino’s, this time pulling a jackpot lever.
- Codes in the open: Its promotions page lists more than a dozen coupon codes for anyone to see, from no-deposit free spins to no-max matched deposit bonuses, while Silver Oak Casino’s shows four.
- A bigger welcome offer: The welcome bonus is a 285% matched deposit bonus plus 77 free spins, against Silver Oak Casino’s 260% and 35 spins.
- More crypto: It accepts Tether, USD Coin, Dogecoin, and Bitcoin Lightning, in addition to Bitcoin, Litecoin, and Ethereum, which Silver Oak Casino also accepts.
- Daily free spins: A Daily Free Spins promotion offers up to 100 spins a day with no deposit needed.
- Best for: Players who prefer choosing a bonus for every deposit rather than waiting to be offered one.
Ruby Slots
- The ruby one: Ruby Slots is red and black and scattered with gems, with a red-armoured samurai woman much like the one on Silver Oak Casino’s homepage.
- No playthrough: The homepage headline promotes its 250% bonus, code RUBY250, with “No Playthrough”, “No Max Cashout” and a £30 minimum deposit.
- A sneaky cap: Lower down on the same page, the welcome bonus becomes 250% plus 25 free spins with “Low Wagering Requirements” and winnings capped at £1,000, so the information is inconsistent.
- Email only: Its Contact Us page gives one address, support@rubyslotsmail.com, with replies within 48 hours, the same arrangement as Silver Oak Casino’s.
- Same sign-up service: New accounts open through Inclave, a separate login service Silver Oak Casino also uses.
- Best for: Players who’d take a smaller welcome bonus boost percentage for the promise of no wagering, as long as they check which version of the offer applies.
Dreams Casino
- The genie one: Dreams Casino is bright purple and blue, with a grinning genie and his sidekicks floating among gold coins.
- Paid in a day: Its promotions page promises “Get paid in 24H or less”, a much more confident line than Silver Oak Casino’s “within a few days”.
- A similar welcome bonus: The welcome bonus is 250% plus 40 free spins, slightly lower than Silver Oak Casino’s percentage but with five more spins.
- Lighter wagering: A 200% no-max bonus with 50 free spins requires a 15x playthrough on a £50 deposit, well below Silver Oak Casino’s 40x general terms.
- The same hole in support: Its homepage promises live chat, email, and phone support at all hours, but the contact page lists only one email address: support@dreamsmails.com.
- Best for: Players drawn in by a 24-hour payout promise, who’ll be ready to hold the casino to it.
Planet 7 Casino
- The space one: Planet 7 Casino is dark red and black, with a logo that turns its 7 into a ringed yellow planet and an “Escape to Planet 7” tagline.
- Spins every day: Its Spins to Win promotion adds 14 free spins a day for 14 days after a £30+ deposit, for 196 spins total, on top of whatever bonus you’ve chosen.
- A smaller welcome bonus: Its welcome offer is a 200% bonus, below Silver Oak Casino’s 260%.
- A monthly no-max offer: A monthly promotion pairs a 275% bonus with no cap on winnings with 25 free spins on a featured slot.
- The same new slots: Shadow Gods, Crimson Castle and Treasure Sparks are in the spotlight on its homepage, just as they are at Silver Oak.
- Best for: Regular depositors who will happily take a fortnight of daily free spins.
How this Silver Oak Casino review was made
This is what my Silver Oak Casino review is based on, and my About Us page sets out the approach I take with every casino.
Rob Hill
I tested Silver Oak Casino as a new player in the countries it accepts would see it, checked its homepage promises against its terms, and checked the licence it claims against the regulator’s records instead of trusting the casino’s own say-so.

Silver Oak Casino: homepage, Promotions, VIP Program, Refer and Earn, Banking (deposits and withdrawals), Contact Us, FAQ, About Us, Meet the Team, Responsible Gambling, Terms and Conditions, the games lobby and the sign-up form; the page Silver Oak Casino shows UK visitors; the Anjouan Gaming public licence register, its licence status definitions and its enforcement page; the Anjouan validation pages behind the seals on Slots of Vegas, Ruby Slots and Raging Bull Slots; the homepages, promotions, contact pages and terms of Raging Bull Slots, Slots of Vegas, Ruby Slots, Dreams Casino and Planet 7 Casino; the terms of Prism Casino, Slot Madness, Crypto Loko, Captain Jack Casino, CoolCat Casino, Club Player Casino and Palace of Chance; Trustpilot, a casino forum thread and an American consumer complaints service; google.co.uk; and, behind my closing UK suggestion, grosvenorcasinos.com and Rank Interactive (Gibraltar) Limited’s entry on the Gambling Commission register.
Published 19 October 2026
The Anjouan licence doesn’t check out
Silver Oak Casino’s footer doesn’t name a company or a licence. You have to open the terms to learn it’s run by Primrose Media Limited, company number 15804, based in Hamchako, Mutsamudu, on the Autonomous Island of Anjouan in the Union of Comoros. The terms say the casino is “Licensed in the State of Anjouan” under the island’s Computer Gaming Licensing Act, but they don’t give a licence number, and the site shows no licence seal. The FAQ is more confident, answering “Is Silver Oak licensed?” with “Yes, we are completely licensed”.
Three of its sister sites go further. Raging Bull Slots, Slots of Vegas and Ruby Slots name Primrose Media in their footers, quote licence number ALSI-202409021-F12 and show an Anjouan Gaming seal. Click any of those seals, and the validation page that opens says “Operating status: INVALID”. The same page lists the places the licence doesn’t cover, and the USA and the UK are both on that list. On top of that, Anjouan Gaming’s public licence register, which holds more than 1,300 licences, has no entry for Primrose Media Limited, for that licence number, or for any of the Silver Oak Casino sister sites.
Silver Oak Casino is plainly aimed at Americans. It works in US dollars, accepts players aged 21 and up, leaves the US off its list of barred countries, and answers “Will my winnings be reported to the IRS?” with “Of course not.” Selling itself to American players on the strength of a licence whose own validation page says it doesn’t cover players in the UK is downright misleading, and I wouldn’t trust this casino with my money.
Thirteen casinos name Primrose Media Limited as their owner: Silver Oak Casino, the five profiled above, and Prism Casino, Slot Madness, Crypto Loko, Captain Jack Casino, CoolCat Casino, Club Player Casino and Palace of Chance. If you fall out with Silver Oak Casino, its terms send you to the Central Dispute System, which they describe as a third-party service “established by our software provider”, and they add that “all decisions made by the Casino are final”.
Fast withdrawals (according to the homepage)
Silver Oak Casino operates in US dollars, so I’ve converted all the relevant figures into pounds using a 1:1 rate. Deposits by Bitcoin, Litecoin and Ethereum are free, take two or three minutes, and run from £30 to £100,000. Visa, Mastercard, American Express and Discover cards are instant but cost 3% to 10% in fees, with a £1,000 ceiling, and Changelly takes £60 to £200 with no fee.
Withdrawals are a different story. Bitcoin pays out from £50 with fees of up to £40, bank transfer starts at £100 and costs up to £20, and a check transfer needs £100 and can cost £25, with all three taking 7 to 10 days. CoinDraw is the only quicker route, at up to seven days for a 5% fee, from £20. Every method stops at £2,500, and anyone who deposited by card can’t be paid back to it.
The terms make it slower still. Withdrawals are approved within 7 to 10 business days of the request, then paid within another 7 to 10 business days after approval, and no more than £2,500 is sent in any week. Monthly withdrawals top out at £10,000, or £5,000 if your balance is at least ten times what you’ve deposited, and if you haven’t wagered your deposit at least once there’s an 8% fee, with a £4 minimum, on top of the method’s charge. Totted up, that’s up to four working weeks before a payout arrives, and a £10,000 win would come in four weekly pieces after that. Yet the homepage sells “FAST WITHDRAWALS” and says it aims to have the money “on its way to you within a few days”. That isn’t a slight exaggeration; it’s another example of the casino misleading would-be players.
260% deposit boosts on the banner, 40x wagering in the terms
The welcome offer, with code SILVER260, gives you a 260% matched deposit bonus and 35 free spins. Other codes on the promotions page include WELCOME100, for 100% and 20 free spins on Vegas Lux, WILD110, for 110% and 25 spins on Wild Fire 7s, and a free-spins code for the game of the month. The same page promises “Deposit £100 and play with £400”. Totted up, a 260% bonus on £100 gives you £360 to play with, not £400, so someone’s fluffed their maths.
The general terms do the heavy lifting. Bonuses require a 40x playthrough on slots, keno, bingo, plinko, and scratch cards, and 60x on table games and video poker, while baccarat, craps, roulette, crash games, Pai Gow Poker, Pontoon 21, and Sic Bo don’t count at all. You can’t cash out deposit bonuses, and they’re deducted from your balance when you withdraw. Free chips that require no deposit pay out no more than the bonus value, with a £100 minimum. Before your first payout, you must make an £11 Litecoin deposit to verify your crypto wallet, and winnings are paid in crypto. Weekly cashback has its own 40x playthrough, and comp points convert at 100 points to £1. For comparison, a UK casino can’t ask for more than 10x on any bonus.
VIP levels you can buy
The VIP Program has five levels, and each includes a “Buy instant level upgrade” offer, priced from £500 for the first level to £8,000 for the top. The top level brings a £700 appreciation chip, deposit bonuses of up to 325% (400% on Bitcoin), 35% monthly cashback, a £3,000 birthday bonus for players who’ve deposited £5,000 in the last 90 days, bets of up to £10,000, and withdrawals of up to £7,500 a week. The first level gets 4% monthly cashback, £500 in free bets and the standard £2,500 a week.
I don’t like it. Selling a quicker route to your own winnings, plus bigger bonuses to keep you playing, for a one-off payment of up to £8,000 is the opposite of what a responsible casino should do. The Refer and Earn scheme is tamer, giving up to 14 friends a £100 free chip each, with rewards for you once they deposit.
Cartoon heroes and 263 RealTime Gaming games
The casino’s aesthetic is cheerful. Silver Oak Casino’s homepage features a big oak tree with silver-white leaves over hills of gold coins, with Zeus, a samurai woman, a laughing baby Buddha, a chick hatching from its egg and a masked robber with a bag of loot gathered underneath. Pale blue, gold and coral keep it light, and the Game of the Month machine in the middle was showing Great Temple on the day I wrote these words.
The homepage claims “over 180+ games”, which undersells it, because the All Games list runs to 263: 228 slots, 15 video poker games, 11 table games and 9 speciality games. They come from RealTime Gaming, whose random number generator the FAQ says has been certified by Technical Systems Testing. Shadow Gods, Crimson Castle, Treasure Sparks, Fu Long Treasures and Winnie the Piggie Las Vegas lead the new games, with Cash Chaser, Yin-Yang Clash and Mask of the Golden Sphinx among the popular ones. There’s a jackpot counter of just over £521,000 on the homepage, next to a “Recent Jackpot Winner” panel that was celebrating a win of £106.18, which is honest of it, if nothing else.
Support by email only (whatever the homepage says)
The homepage says the support team “can be contacted via email, phone, or live chat around the clock”. The Contact Us page offers a form and one email address, help@silveroakmail.com, with replies within 48 hours, and no phone number. Visitors from countries the casino blocks are given a different address, help@silveroakcasino.com. Even the VIP page says, “Our live 24/7 is ready to assist you. Contact us via email”, which doesn’t clarify things.
According to the terms, self-exclusion works through live chat, and limits are set through chat or email. The Responsible Gambling page is a long essay that links to Gamblers Anonymous, the National Council on Problem Gambling and Gambling Therapy, but it has no tools of its own. The Meet the Team page describes one of its writers as seeing gambling as “a basic human right” and not understanding “all the fuss about casinos”, which is odd language and framing for a casino to run with.
If something goes wrong, you have three days from the bet being settled to raise a dispute, and no claims are honoured after that. The terms also cap the casino’s liability at £500, and an account that goes unused for two years can be deleted, with any remaining balance confiscated.
Silver Oak Casino’s reputation
Silver Oak Casino’s Trustpilot page has a 1.4 rating from 101 reviews. The casino hasn’t claimed the profile, and almost all of the recent reviews give one star.
Most of the complaints are about money. Players describe withdrawals still waiting weeks after their documents were approved, being told time and again that a payment was on its way, being asked to verify an account they’d already verified, and winnings taken back under bonus rules. None of that surprises me, given terms that allow up to four working weeks for a payout, cap weekly payouts at £2,500, and remove deposit bonuses at withdrawal. The story is similar on an American consumer complaints website, which lists 21 complaints about Silver Oak Casino in the last three years, five in the past year, with the most recent marked as unanswered.
A balanced view
Points in its favour
- A cheerful cartoon theme on a site that’s easy to find your way around.
- 263 RealTime Gaming games, including 15 video poker titles.
- Free crypto deposits of up to £100,000.
- Bonus codes listed openly on the promotions page, and available for every deposit.
Points against
- A claimed Anjouan Gaming licence that the regulator doesn’t recognise.
- Up to four working weeks for a payout, despite “FAST WITHDRAWALS” advertising on the homepage.
- Higher VIP levels, and their bigger withdrawal limits, sold for up to £8,000.
- Email-only support, with self-exclusion handled through live chat.
My Silver Oak Casino sister sites verdict: nice to look at, impossible to trust
I’ll give Silver Oak Casino its due. It’s a friendly-looking site with a fair spread of games and quick, free crypto deposits. But once you’ve won, everything that matters goes the wrong way. The licence it depends on can’t be confirmed by the regulator that’s supposed to have issued it, payouts are slow and rationed while the homepage calls them fast, and the easiest way to a better standard of service is to pay for it. Its sister sites share the same owner and the same licensing problem, so moving between them doesn’t fix anything.
With no UK licence and the UK on its list of barred countries, Silver Oak Casino isn’t one for British players. If it’s the big-time casino experience you’re after, Grosvenor Casinos is a much safer bet. It’s the online side of Grosvenor’s chain of real UK casinos, licensed by the Gambling Commission to Rank Interactive (Gibraltar) Limited (account 57924), and new players who deposit £20 get a £40 bonus plus 100 free spins on Big Bass Splash.
