Silver Oak Casino Sister Sites — Investigation Overview

Silver Oak Casino launched around 2008–2009 and is operated by BTK Ltd, a company also referred to as Ace Revenue Group. The corporate ownership chain runs through multiple layers: the Virtual Casino Group sits at the top, followed by Crystal Palace Group (a rebrand), which connects to BTK Ltd and the Ace Revenue affiliate programme. No registration number or registered address could be independently verified for any entity in this chain. The operator claims a Costa Rica jurisdiction, but Costa Rica does not issue traditional gambling licences with public registers, regulatory oversight, or player dispute mechanisms. Casino Guru explicitly states that Silver Oak Casino does not hold any official gambling licence as far as they are aware. One unverified blog claimed Curaçao CGA and MGA affiliation, but searches of the Curaçao Gaming Control Board public register at gamingcontrol.cw and the Malta Gaming Authority licence check tool at mga.org.mt returned no matching results for Silver Oak, BTK Ltd, Ace Revenue, Virtual Casino Group, or Crystal Palace Group. CasinoListings.com permanently blacklisted the entire Virtual Casino Group in March 2010. The Better Business Bureau assigns Silver Oak Casino an F rating with 18 unresolved complaints. Casino Guru gives the site a 7.7 Safety Index (Above Average), yet notes 15 direct complaints and 289 from related casinos totalling 1,574 black points. Despite this troubled background, the brand maintains a presence in the US-facing market powered exclusively by RealTime Gaming (RTG). This investigation documents all verified Silver Oak Casino sister sites, their shared risks, and what players should know before depositing.

What Are Silver Oak Casino Sister Sites?

Silver Oak Casino sister sites are online casinos that share beneficial ownership through the BTK Ltd / Virtual Casino Group corporate structure and operate on the same Costa Rica jurisdiction claim. All identified sisters run exclusively on RealTime Gaming software and target the US market. Because none of these brands hold a UK Gambling Commission licence, none are enrolled in GamStop. UK players who have self-excluded via GamStop receive zero automatic protection at any Silver Oak Casino sister sites — self-exclusion must be arranged individually with each brand, and there is no regulatory body to enforce compliance. Similarly, there is no mandatory fund segregation, no independent ADR provider, and no enforceable withdrawal timeframe across the network. Six sister brands were confirmed through cross-referencing multiple industry databases, watchdog reports, and affiliate disclosures. Given that the Virtual Casino Group reportedly operates upwards of 25 interconnected casinos, these six represent a verified subset rather than an exhaustive list.

Silver Oak Casino Sister Sites — Complete List

All six confirmed sister sites share the same Costa Rica jurisdiction claim through BTK Ltd / Ace Revenue Group. No verifiable licence number exists for any brand in the network. Every site runs on the RealTime Gaming platform and targets US-based players.

Brand Specialty Welcome Bonus Wagering Min Deposit
Planet 7 Casino Slots and table games, no deposit bonuses Up to 450% + Free Spins 20x(D+B) match; 30x no deposit $30
Royal Ace Casino VIP-oriented RTG experience
Captain Jack Casino Pirate-themed RTG casino
Slot Madness Slots-focused with progressives 275% + 50 Free Spins
Raging Bull Casino High-value bonus, low wagering on USD 410% up to $10,000 10x USD; 40x crypto
Slots Garden RTG slots-focused

The em-dash entries above reflect a deliberate data gap: the Virtual Casino Group does not publish standardised bonus or deposit information across its brands. Individual terms frequently change and are often distributed through coupon code aggregator sites rather than on the casinos themselves, making long-term verification difficult.

The table below provides a qualitative verdict on each brand based on the depth of verifiable data obtained during this investigation.

Brand Data Verified Bonus Rating UX Differentiation Best Suited For
Planet 7 Casino High Strong Standard US bonus code hunters
Royal Ace Casino Medium Unverified Standard VIP/high-roller segment
Captain Jack Casino Low Unverified Distinctive Casual players seeking novelty theme
Slot Madness Medium Standard Standard Dedicated slots enthusiasts
Raging Bull Casino Medium Strong Distinctive Bonus hunters seeking low wagering
Slots Garden Low Unverified Template

A recurring pattern across all Silver Oak Casino sister sites is the use of an identical platform template. Every brand shares the same RTG game library, the same download client versus instant-play structure, the same cashier interface, and the same customer support team. Visual theming differs — pirate graphics at Captain Jack, Vegas imagery at Royal Ace — but underlying functionality is indistinguishable. This platform uniformity explains why per-brand operational data is sparse: the casinos are functionally the same product with different skins.

Planet 7 Casino

Planet 7 Casino at planet7casino.com is the most widely documented brand in the BTK Ltd network and serves as the primary sister to Silver Oak. The site hosts over 200 games exclusively from RealTime Gaming, spanning slots, table games, video poker, and specialty titles. Planet 7’s welcome package reaches up to 450% in deposit match bonuses with free spins attached, and new players can claim a $25 no deposit free chip. Match bonus wagering sits at 20x the combined deposit and bonus amount, while no deposit free chips carry a 30x requirement — relatively moderate compared to industry averages. Deposits start at $30 via Visa, MasterCard, American Express, Bitcoin, Litecoin, Ethereum, or bank wire. The site frequently distributes no deposit bonus codes with low 5–10x wagering on free spins, which makes it a magnet for bonus code aggregator sites. Planet 7 runs a tiered VIP programme and offers so-called

Frequently Asked Questions

Does Silver Oak Casino hold a verified gambling licence?+
No. Casino Guru states Silver Oak Casino does not hold any official gambling licence as far as they are aware. The operator claims a Costa Rica jurisdiction, but Costa Rica does not issue gambling licences with regulatory oversight. Searches of the Curacao Gaming Control Board and Malta Gaming Authority registers returned no results for Silver Oak or its parent companies.
How many Silver Oak Casino sister sites are there?+
This investigation confirmed six sister sites: Planet 7 Casino, Royal Ace Casino, Captain Jack Casino, Slot Madness, Raging Bull Casino, and Slots Garden. All are linked through BTK Ltd and the Virtual Casino Group. The wider network may include additional brands, as Casino Guru identifies 25 interconnected casinos.
Is Silver Oak Casino enrolled in GamStop?+
No. GamStop enrolment requires a UK Gambling Commission licence, which Silver Oak Casino does not hold. UK players who have self-excluded through GamStop are not automatically blocked from Silver Oak or any of its sister sites. Self-exclusion must be arranged directly with each brand individually.
Why do Silver Oak Casino withdrawals take so long?+
Withdrawal delays are the most common complaint across the entire Virtual Casino Group network. The operator claims crypto payouts in under 24 hours, but player reports consistently describe 20 to 25 day wait times. The BBB records 18 unresolved complaints and Casino Guru has accumulated 1,574 black points across the group. There is no regulatory body to enforce withdrawal timeframes.
Does Raging Bull Casino have a different licence from Silver Oak?+
Yes. Raging Bull Casino holds a separate licence from the Anjouan Gaming Board, an offshore authority based in the Comoros Islands. The rest of the Silver Oak sister sites operate solely under the Costa Rica jurisdiction claim. However, the Anjouan Gaming Board provides minimal regulatory oversight compared to authorities like the MGA or UKGC.
