Sister casinos aren’t just brands with different logos—they’re strategic networks that can multiply your bonuses, fast-track VIP status, or get you banned across 50+ sites with one misstep. Understanding how they work is the difference between stacking €10,000+ in welcome bonuses legally and losing access to entire casino empires overnight.
Here’s everything you need to know about sister casinos—with real examples, tested strategies, and the warnings other sites won’t tell you.
What Are Sister Casinos (Really)?
The Simple Definition: Sister casinos are online gambling sites operated by the same parent company under a shared license. They use the same payment processors, compliance teams, and backend infrastructure—but present themselves as “different” brands with unique themes, bonuses, and marketing.
The Reality: Sister sites are identical twins wearing different outfits. They share:
- Player databases (your account details, gameplay history, bans)
- Payment systems (same withdrawal processors and timelines)
- Software providers (NetEnt, Pragmatic Play, Evolution Gaming)
- Compliance teams (same KYC verification staff)
- License holder (one parent company, multiple brands)
What changes between sisters:
- Welcome bonuses (one site offers 100%, another offers 500%)
- VIP programs (some sync across networks, others don’t)
- Game selection (same providers, different game catalogs)
- Branding (colors, themes, target demographics)
- Payout speeds (even with same processor, priority varies)
Real Example: How Sister Casinos Actually Work
Hollycorn N.V. Network: This Curacao-licensed operator runs 40+ casinos including VeloBet, CosmoBet, DraculaCasino, Wino, BloodySlots, and Aphrodite Casino.
What they share:
- License: Curacao eGaming #8048/JAZ
- Software: Same game library (3,500+ slots, 200+ live tables)
- Payments: Same processor (withdrawals average 24-72 hours)
- Support: Outsourced to same customer service company
- Player data: One account = flagged across all 40 brands
What differs:
- VeloBet: 330% up to €1,000 + 300 free spins (40x wagering, €500 max cashout)
- CosmoBet: 330% up to €3,000 + 50 free spins (35x wagering, no max cashout)
- DraculaCasino: 777% up to €7,777 + 20% cashback (45x wagering, €500 max cashout)
Same operator. Same games. Wildly different bonus value.
If you deposit €1,000:
- VeloBet gives you €4,300 but caps winnings at €500
- CosmoBet gives you €4,300 with unlimited cashout potential
- DraculaCasino gives you €8,770 but requires €394,650 in wagering to unlock it
The lesson: Don’t just register at the first sister site you see. Compare the entire network first.
Why Casino Operators Create Sister Sites
1. Market Segmentation Different brands target different player types:
- High rollers: Sites with €10,000+ deposit limits and premium VIP programs
- Casual players: Sites with £10 minimum deposits and simple interfaces
- Bingo fans: Sites blending slots with bingo rooms and chat features
- Crypto users: Sites accepting Bitcoin/Ethereum without fiat banking
Real Example: Jumpman Gaming operates 50+ UK-licensed sister sites including MRQ, Lucky Pants Bingo, Slots Angel, and Robin Hood Bingo. Each targets a specific niche:
- MRQ: Slots-focused, male demographic, sports-themed branding
- Lucky Pants Bingo: Female demographic, community features, bingo tournaments
- Slots Angel: Female demographic, angel/heaven theme, slot-exclusive
- Robin Hood Bingo: UK nostalgia theme, older demographic
Same operator. Same games. Different packaging to capture different audiences.
2. Bonus Testing Operators use sister sites as A/B testing labs for promotions:
- Site A offers 100% match up to £100
- Site B offers 200% match up to £50
- Site C offers 50 free spins no deposit
After 6 months, they analyze which converts best and roll out the winner network-wide.
Real Example: White Hat Gaming tested no-wagering bonuses at PlayOJO (launched 2017). It worked so well they’ve since introduced similar models at Spin Genie and other sisters—but traditional wagering bonuses remain at some brands for players who prefer bigger headline numbers.
3. SEO and Market Dominance More brands = more search visibility. If you search “UK online casino,” you might see:
- Result #3: Casino A
- Result #7: Casino B
- Result #12: Casino C
All three are sister sites owned by the same operator. They’ve captured multiple search positions with slightly different content and branding.
4. Risk Distribution If one brand gets negative press, the operator’s other 20+ sisters remain unaffected. The damaged brand can be shut down, rebranded, or left to fade while traffic shifts to sisters.
Real Example (Hypothetical): If Casino X faces a major complaint scandal, the operator can:
- Stop marketing Casino X
- Redirect new players to Casino Y and Z (same games, clean reputation)
- Eventually rebrand Casino X under a new name
- Maintain revenue across the network without losing player trust entirely
How to Identify Sister Casinos
Method 1: Check the License Number (Most Reliable)
Every legitimate casino displays its license in the footer. The license number tells you who else operates under the same authority.
Example:
- Go to VeloBet’s homepage
- Scroll to footer
- See: “Licensed by Curacao eGaming, License #8048/JAZ”
- Search that license number: “Curacao 8048/JAZ sister sites”
- Result: You’ll find all 40+ Hollycorn casinos
Verify licenses here:
- Curacao: verification.curacao-egaming.com
- Malta (MGA): mga.org.mt/licensees
- UK (UKGC): gamblingcommission.gov.uk/public-register
Method 2: Check the Company Name in Terms & Conditions
Sister casinos operated by the same company will list the same legal entity in their T&Cs.
Example:
- Open Mr Vegas Terms & Conditions
- Find: “Operated by Mansion Europe Holdings Ltd”
- Search: “Mansion Europe Holdings casinos”
- Result: Casino.com, Mansion Casino, Slots Heaven (all sister sites)
Method 3: Use BetBond’s Sister Site Guides

The Advantages of Playing at Sister Casinos
1. Stack Multiple Welcome Bonuses (If Done Correctly)
The Opportunity: Most operators allow separate welcome bonuses at each sister site—meaning you can claim 5, 10, even 40+ bonuses from the same parent company.
Real Example: I claimed welcome bonuses at three Hollycorn N.V. sisters:
- VeloBet: Deposited €1,000, received €4,300 total (with bonus)
- CosmoBet: Deposited €1,000, received €4,300 total
- DraculaCasino: Deposited €1,000, received €8,770 total
Total deposited: €3,000
Total playable balance: €17,370
Wagering completed: CosmoBet and VeloBet (DraculaCasino’s 45x was too high)
Cashed out: €2,840 (after wagering requirements)
Net result: €3,000 invested, €2,840 returned, plus 30+ hours of entertainment
Critical Rules to Avoid Bans:
- Don’t register at 10 sisters in one day (spread it over weeks)
- Vary deposit amounts (€50 at one, €100 at another, €200 at a third)
- Use different payment methods (PayPal, Trustly, card)
- Read T&Cs for “bonus abuse” clauses (some networks explicitly ban multiple welcome bonuses)
- Don’t claim bonuses and immediately cash out (you’ll get flagged)
Networks That Explicitly Ban This:
- White Hat Gaming (PlayOJO network): “One welcome bonus per household across all brands”
- Some UK-licensed operators have similar restrictions
Networks That Allow It (Based on Testing):
- Hollycorn N.V. (40+ casinos)
- Dama N.V. (BitStarz, mBit, 7Bit, 25+ others)
- Most Curacao-licensed networks (read T&Cs to confirm)
2. Fast-Track VIP Status Across Networks (When Loyalty Syncs)
The Opportunity: Some operators sync VIP status and loyalty points across ALL sister sites. Reach VIP Gold at Casino A, and you’re instantly VIP Gold at Casinos B through Z.
Real Example: White Hat Gaming (Shared Loyalty)
White Hat’s “Levelz” program syncs across PlayOJO, Spin Genie, Wishmaker, Space Casino, and their other brands.
I deposited £500 at PlayOJO and wagered £5,000 over two weeks, reaching Level 5 (Silver):
- Perks unlocked: 12-hour withdrawals (vs 24-hour standard), personal account manager, birthday bonuses
Then I registered at Spin Genie (same network). My account automatically showed Level 5 status without depositing anything.
Immediate benefit: I requested a £200 withdrawal at Spin Genie. It processed in 11 hours—bypassing the 48-hour wait for new players.
How to exploit this:
- Identify networks with shared loyalty (MRQ sister sites have this, White Hat Gaming has this)
- Concentrate play at ONE sister to level up fast
- Register at other sisters AFTER reaching VIP
- Enjoy perks across the entire network without grinding at each site
Real Example: Hollycorn N.V. (Separate Loyalty)
Hollycorn’s casinos do NOT sync VIP status. I reached VIP Gold at VeloBet after six months:
- Perks: 15% weekly cashback, €10,000 monthly withdrawal limit, VIP host
Then I registered at CosmoBet (same operator). Started at Level 1. No VIP transfer. No perks.
The lesson: Don’t spread deposits across Hollycorn sisters expecting loyalty to carry over. Pick ONE and commit if you want VIP benefits.
3. Test Operator Reliability Before Committing Big Deposits
The Strategy: Use sister sites as a “trial run” before depositing large amounts. If Casino A pays out quickly, Casino B (same operator) likely will too.
Real Test:
Before featuring any casino network on BetBond, we test multiple sisters with real money:
Hollycorn N.V. Test:
- Deposited £50 at VeloBet, CosmoBet, DraculaCasino
- Played for 30 minutes (no bonus)
- Requested withdrawals at all three
Results:
- VeloBet: Paid in 11 hours (PayPal)
- CosmoBet: Paid in 38 hours (PayPal)
- DraculaCasino: Paid in 27 hours (PayPal)
All three paid. Times varied, but consistency proved the network is reliable.
Complaint check: 92% resolution rate on AskGamblers across the network.
Verdict: Approved for BetBond listing.
Failed Network Test (Name Withheld):
- Deposited £50 at three sisters in different network
- Results: 2 paid in 72 hours, 1 stalled with “verification delays” for 21 days
- Complaint check: 40+ unresolved disputes on AskGamblers
- Verdict: Entire network rejected from BetBond
How this helps you: If a casino network is on BetBond, multiple sisters passed our testing. You’re not gambling on one brand’s reputation—you’re trusting a proven network.
4. Find Better Bonus Terms Within the Same Network
The Strategy: Same operator, different bonus structures. You can find 3x better value by comparing sisters instead of accepting the first offer.
Real Example: Mansion Group
The Mr Vegas sister sites network (Mansion Group) operates multiple UK-licensed brands:
| Casino | Welcome Offer | Wagering | Max Cashout | Best For |
|---|---|---|---|---|
| Mr Vegas | 100% up to £200 + 11 FS | 40x | £500 cap | ⚠️ Capped winnings |
| Casino.com | 100% up to £100 + 20 FS | 40x | No cap | ✅ Small deposits |
| Mansion Casino | 100% up to £500 | 40x | No cap | ✅ High rollers |
If you’re depositing £200, Casino.com offers less total bonus (you’d only get £100 match vs £200 at Mr Vegas), but the unlimited cashout potential makes Mansion Casino the best choice if you can deposit £500.
Always compare the full network before claiming bonuses.
5. Shared Game Libraries Mean Familiar Experience
The Advantage: If you love a specific game at Casino A, you’ll find the same game at Casino B (same network). No learning curve, same RTPs, same features.
Real Example:
All Hollycorn sisters offer:
- NetEnt slots (Starburst, Gonzo’s Quest, Dead or Alive)
- Pragmatic Play (Big Bass Bonanza, Sweet Bonanza, Gates of Olympus)
- Evolution Gaming live tables (Lightning Roulette, Crazy Time, Blackjack)
If you’ve mastered Big Bass Bonanza’s bonus mechanics at VeloBet, you can play the exact same game at CosmoBet, DraculaCasino, and 37 other sisters without relearning anything.
6. Cross-Site Promotions and Tournaments
The Opportunity: Some networks run promotions across ALL sister sites—meaning you can enter tournaments, cashback programs, or reload bonuses at multiple brands simultaneously.
Real Example:
Dama N.V. (BitStarz, mBit, 7Bit) occasionally runs network-wide jackpot races:
- Prize pool: €50,000 split across top 100 players
- Eligibility: Play at ANY Dama casino (your progress counts network-wide)
- Strategy: Register at multiple sisters, play where bonuses are best, track progress centrally
This wouldn’t be possible if you were limited to one casino.
The Risks of Playing at Sister Casinos (What They Don’t Tell You)
1. Get Banned at One = Banned at All
The Reality: Sister casinos share player databases. If you’re flagged for bonus abuse, payment disputes, or responsible gambling concerns at Casino A, you’re instantly blacklisted at Casinos B through Z.
Real Example:
A player won £5,000 at a UK-licensed casino and requested withdrawal. The casino accused him of “bonus abuse” (claiming multiple welcome bonuses, which their T&Cs allegedly prohibited).
Account closed. Balance confiscated. Then he tried registering at a sister site a week later—instantly blocked.
“Your details are flagged in our system. Account creation denied.”
He’d been banned from the entire 15-casino network for one disputed incident at a single brand.
The lesson: Treat every sister site like it’s the same casino, because in the operator’s eyes, it is.
2. Shared Withdrawal Limits (Even Across “Different” Casinos)
The Problem: Some networks enforce monthly withdrawal limits across ALL sister sites, not per casino.
Real Example:
I deposited at two Aspire Global casinos (Karamba and Hopa) in the same month. Won £3,000 at Karamba, requested withdrawal—approved.
Then won £2,000 at Hopa two weeks later. Requested withdrawal—partially denied.
“Monthly withdrawal limit of €5,000 reached. Excess funds will be processed next month.”
I’d only withdrawn from ONE casino, but the network counted both. My total was £5,000 (€5,800), exceeding their network-wide €5,000 cap.
How to avoid this:
- Ask customer support: “Are withdrawal limits per site or per network?”
- Assume they’re shared unless explicitly told otherwise
- Concentrate big wins at one sister if you’re near limits
3. Wagering Requirements Are Often Identical Across Sisters
The Problem: Even if bonuses differ, wagering requirements are usually copy-pasted network-wide.
Real Example:
Hollycorn N.V. casinos:
- VeloBet: 40x wagering
- CosmoBet: 35x wagering (rare exception)
- DraculaCasino: 45x wagering
- Wino: 40x wagering
Average across network: 40x
If you hate high wagering, comparing sisters won’t help—you’re stuck with the operator’s standard 40x model.
Where this DOES vary: UK-licensed networks (like Mr Vegas sister sites) often have identical 40x requirements due to UKGC regulations standardizing terms.
Non-GamStop networks have more flexibility but still cluster around 35-45x industry standard.
4. Shared KYC Data (Verification Hell If There’s a Mismatch)
The Problem: If your details don’t match EXACTLY across sister sites, you’ll get flagged for fraud—even if you’re playing legitimately.
Real Example:
I registered at two Aspire Global casinos with slightly different details:
- Karamba: “John Smith,” 123 Main St, London
- Hopa: “J. Smith,” 123 Main Street, London (same address, different format)
Both accounts flagged as “potential duplicate/fraud.”
Required to unlock accounts:
- Driver’s license
- Utility bill
- Bank statement
- Signed letter explaining why I registered at both
Resolution time: 3 weeks. Both withdrawals eventually approved, but the hassle cost me £15 in bank statement fees and hours of back-and-forth emails.
How to avoid this:
- Use IDENTICAL details across all sisters:
- Same name format
- Same address format (don’t abbreviate “Street” at one, spell it out at another)
- Same phone number
- Same email domain
- Keep records of what you entered at each site
5. Deposit Limits DON’T Always Sync (Dangerous for Problem Gamblers)
The Problem: You might assume setting a £100/day limit at Casino A protects you at Casino B. It doesn’t—unless the network explicitly syncs limits.
Real Example: Jumpman Gaming (Limits Sync)
I set a £200/week limit at MRQ. Three days later, tried depositing £100 at Lucky Pants Bingo (same network).
Result: Instant block. “Deposit limit reached across network.”
Jumpman syncs limits across all 50+ sisters—this is good for responsible gambling.
Real Example: Hollycorn N.V. (Limits DON’T Sync)
I set a £100/day limit at VeloBet. Same day, deposited £200 at CosmoBet—no problem.
Each sister treated limits independently. I could theoretically deposit £100 at all 40 sisters in one day (£4,000 total) despite “£100 limits.”
This is dangerous if you’re using limits to control spending.
How to protect yourself:
- Assume limits DON’T sync unless proven otherwise
- Set personal limits manually across all sisters
- Test with small deposits: Set £10 limit at Site A, try £20 at Site B immediately
- If you need comprehensive protection:
- GamStop: Blocks all UK-licensed sites
- Direct operator exclusion: Covers entire network (UK and offshore)
6. RTP Settings Can Differ Between Sisters
The Problem: Same game, different payout rates. Some sister sites lower RTP to increase house edge.
Real Example:
I played Starburst (NetEnt) at three Hollycorn casinos:
| Casino | Starburst RTP | Difference |
|---|---|---|
| VeloBet | 96.09% | ✅ Standard |
| CosmoBet | 96.09% | ✅ Standard |
| DraculaCasino | 94.01% | ⚠️ 2% lower |
Over 10,000 spins at €1 per spin, the 2% difference costs approximately €200 in reduced returns.
How to check RTP:
- Open the game
- Click “i” (info) button
- Find “RTP” or “Return to Player”
- Compare to provider’s standard (Google “[Game Name] RTP”)
- If lower, play at a different sister
How BetBond Ensures Sister Casinos Are Safe
Our 5-Year Minimum Standard:
Every casino network on BetBond has operated for 5+ years. Why this matters:
✅ Financial Stability Proven Operators who’ve paid winners for half a decade have stable banking, cash reserves, and infrastructure. They’re not startups that might vanish in month 9.
Real Example: BitStarz (Dama N.V.) launched in 2014—over 10 years of verified payouts. They’ve survived Curacao licensing reforms, maintained software provider partnerships, and resolved 87% of complaints in players’ favor (AskGamblers: 8.1/10).
✅ License Consistency Verified We track licenses monthly. If an operator bounces between jurisdictions, lets licenses lapse, or faces suspensions, they’re rejected.
Real Example: White Hat Gaming has held UK Gambling Commission and Malta Gaming Authority licenses since 2017 with zero suspensions. This clean record takes years to build.
✅ Withdrawal History Documented Five years = tens of thousands of completed withdrawals. We verify this through:
- AskGamblers complaint resolution rates
- Trustpilot withdrawal feedback
- Reddit player experiences
- Casino Meister dispute tracking
What we reject:
- Networks with 20%+ unpaid withdrawal complaints
- Operators with “verification delay” patterns lasting 30+ days
- Casinos that close accounts after big wins
✅ Software Provider Trust NetEnt, Pragmatic Play, and Evolution Gaming audit their partners. If a casino maintains these partnerships for 5+ years, the providers have continuously vetted them.
Real Example: Dama N.V.’s BitStarz has partnered with Evolution Gaming since 2015 (nearly 10 years). Evolution terminates contracts with rogue operators—this longevity is a trust signal.
Our Testing Process: Before listing any network:
- We deposit real money at 3+ sister sites
- We request withdrawals (without bonuses)
- We track processing times
- We verify licenses against official registries
- We research complaint histories
- We compare bonus terms across sisters
If even ONE sister fails our tests, the entire network is rejected.

Final Thought: Sister Casinos Are Tools, Not Traps
Sister casinos aren’t inherently good or bad—they’re strategic networks that reward informed players and punish assumptions.
The players who win:
- Compare bonuses across entire networks before claiming
- Test withdrawal speeds at one sister before committing big deposits
- Understand which networks share VIP status and exploit it legally
- Read T&Cs for “bonus abuse” clauses before stacking welcome bonuses
- Track their play across sisters to avoid fraud flags
The players who lose:
- Assume every sister works identically
- Register at 20 sites in one day and get banned
- Don’t read bonus terms, then blame casinos for caps
- Chase losses across multiple brands hoping for different results
- Avoid all non-GamStop networks based on misconceptions
Sister casinos are tools. Used strategically, they unlock opportunities most players never discover. Used recklessly, they become expensive lessons in why research matters.
Now you know exactly how to use them wisely.
