Mellstroy Casino is an influencer-branded casino built on the 1Win network. You’re essentially playing at 1Win with Mellstroy’s mascot plastered everywhere.
While both Mellstroy and 1Win are well-known names in online gambling, recognition doesn’t equal reliability. The casino has some unfavorable terms buried in the fine print that you should know about before playing here.

Who’s Behind This
The Influencer: Mellstroy (Andrey Burim) is a controversial Belarusian-Russian streamer born December 15, 1998, who gained notoriety through extreme “trash streaming” content. In October 2020, he violently assaulted model Alena Efremova on a live stream watched by 720,000 viewers, leaving her with serious injuries including a broken jaw. He’s currently banned from YouTube, Twitch, and other major platforms.
The Operator: 1Win operates under Curaçao gaming license 8048/JAZ2018-040 through the company 1WIN N.V. (registration 147039), with parent company MFI Investments Limited registered in Cyprus. The platform was founded in 2016 as “FirstBet” and rebranded to 1Win in 2018, claiming over 30 million users. However, 1Win is blocked from all major regulated gambling jurisdictions including the US, UK, EU countries, and Australia, operating primarily in emerging markets.
The Partnership: Mellstroy and 1Win announced a joint casino project in 2024, with Mellstroy claiming he would control design, branding, and even RTP percentages. However, the partnership was suspended due to controversies and a financial dispute, with sources indicating Mellstroy owes 1Win approximately $8.4 million. Apparently, these disputes have been resolved to launch a new casino with Mellstroy’s branding on the 1Win platform.
Red Flags
- 1Win has numerous customer complaints about withdrawal delays, frozen accounts, and unresolved payment issues across Trustpilot and gambling forums
- Mellstroy has systematically failed to honor financial commitments totaling over $14 million across at least seven documented cases
- The Curaçao license offers minimal player protection, and the Gaming Authority explicitly states it doesn’t handle individual player complaints
Registration
Registration offers two paths. Quick registration requires phone number, email, and password. You can also register using your social media accounts, including Google, Telegram, and few others.
Games
The sheer size of the game library is impressive. With 9 000+ games from over 50 providers, you won’t run out of options. Pragmatic Play dominates both slots and live casino. BGaming brings substantial content including proprietary titles. Evolution Gaming handles premium live dealer experiences. Other major providers include Hacksaw Gaming, No Limit City, PG Soft, Endorphina, Playtech, Evoplay, Playson, and dozens more ranging from household names to smaller studios.
Game categories organize the library: Lobby (curated selection), Popular, Mell Originals, Top games, Slots, Roulette, New, Live Casino, Bonus buy, Quick games, Blackjack, Drops & Wins (promotional games), and Bonus Wagering (games where you can use bonus funds). A “Find a game” random selector helps indecisive players.
The platform displays recent big wins in a “Last wins” ticker showing game thumbnails and amounts in various currencies. This social proof element highlights wins ranging from modest to substantial payouts.
These Mellstroy Casino games are also available on Anonymous Casino with much more reliable payout processes.
Slots
Slots selection covers every style. Traditional three-reel classics sit alongside modern video slots with complex bonus features. You’ll find Megaways mechanics, cluster pays, hold-and-win features, and cascading reels. Popular titles getting prominent placement include Sugar Rush 1000, Gates of Olympus (multiple variants), Big Bass Bonanza series, The Dog House Megaways, Sweet Bonanza, Zeus vs Hades Gods of War, Hell Hot 100, 777 Coins, and Olympus Wins Super Scatter.
Many slots offer Bonus Buy features where you can purchase direct access to free spins rounds rather than waiting to trigger them naturally. The casino has a dedicated category for these games.
Progressive jackpots appear throughout the slots library. When we checked, the total jackpot pool showed $11,352,887. A “See all jackpots” button reveals more titles than what displays on the homepage.
Live Casino
Live Casino runs primarily on Evolution Gaming and Pragmatic Play Live. Evolution brings their full suite: multiple roulette variants (including speed, immersive with multiple camera angles, and VIP tables), extensive blackjack options, baccarat, Caribbean Stud Poker, and their signature game shows like Crazy Time, Monopoly Live, Mega Wheel, Deal or No Deal, and Lightning Roulette. Pragmatic Play Live adds more roulette and blackjack tables plus Sweet Bonanza Candyland. Playtech contributes additional live dealer options.
Originals
Mell Originals are proprietary instant games: Coinflip, Penalty, Crash, Dice, Mines, Poker, Double, Keno, Blackjack, and Hilo. These are simple, fast-paced games designed for crypto betting and quick sessions.
Bonuses
Welcome Bonus
The headline offer is 550% bonus plus 400 free spins split across your first four deposits. Here’s exactly how it breaks down.
- First deposit: 100% match bonus up to €110 plus 100 free spins for The Dog House Megaways. Deposit €10 minimum to activate. Deposit €110 to max out the bonus.
- Second deposit: 125% match bonus up to €110 plus 100 free spins for Gates of Olympus 1000. This means depositing €88 maxes out the bonus percentage.
- Third deposit: 150% match bonus up to €110 plus 100 free spins for Big Bass Bonanza. Deposit €73.33 to reach the €110 maximum bonus.
- Fourth deposit: 175% match bonus up to €110 plus 100 free spins for Zeus vs Hades Gods of War. Deposit €62.86 to hit the cap.
Minimum deposit is €10 for each bonus tier. The total maximum bonus across all four deposits is €440 plus 400 free spins if you deposit the optimal amounts. Depositing more than the amounts that trigger maximum bonus is pointless—you won’t get extra bonus funds.
You must activate each bonus within 72 hours of making the deposit or it expires permanently. Once activated, you have exactly 7 days to complete the wagering requirements or the bonus and any winnings from it disappear.
The percentage bonus requires 25x wagering. If you get a €100 bonus, you need to wager €2,500 before you can withdraw. Free spins carry 30x wagering on whatever you win from them. Win €10 from free spins and you need to wager €300. Maximum winnings from free spins are capped at €50—win more and the excess gets confiscated.
You can only have one active Mellstroy Casino bonus at a time. Other bonuses you’ve qualified for sit in a queue under “Available bonuses.” If you activate a new bonus while one is already active, the casino forces you to forfeit the current bonus along with all progress and associated winnings.
Bonuses only work in specific games. You’ll find them listed in the “Bonus Wagering” category under the Casino section. Use your bonus funds elsewhere and the wagering won’t count.
Cashback
The cashback promotion returns a percentage of your net slot losses from the previous week. Credits automatically every Saturday at midnight GMT+3 (overnight from Friday to Saturday) with no wagering requirements—you can withdraw it immediately or use it for play.
The percentage scales based on your total weekly wagers:
- 1% cashback on $1,150 to $3,459 in weekly bets (max $30)
- 2% cashback on $3,460 to $5,759 (max $50)
- 3% cashback on $5,760 to $9,209 (max $60)
- 4% cashback on $9,210 to $11,519 (max $90)
- 5% cashback on $11,520 to $115,169 (max $170)
- 10% cashback on $115,170 to $230,339 (max $230)
- 20% cashback on $230,340 to $575,839 (max $350)
- 30% cashback on $575,840+ (max $580)
The casino advertises up to 30% cashback, which sounds extraordinary. The reality is far less impressive when you calculate what players actually receive.
The structure’s fundamental problem: The cashback percentage scales with your total weekly wagers, not your losses. But the maximum cashback amount is capped far below what those percentages would suggest.
Here’s what happens at each tier:
- 10% cashback tier requires $115,170 in weekly wagers with a maximum cashback of $230. At 96% RTP (industry standard), you’d expect to lose about $4,607 from that volume. Your $230 cashback represents just 5% of your actual losses—not 10%.
- 20% cashback tier requires $230,340 in weekly wagers with a maximum of $350. Expected loss at 96% RTP: $9,214. Your $350 cashback is only 3.8% of actual losses.
- 30% cashback tier requires $575,840 in weekly wagers with a maximum of $580. Expected loss at 96% RTP: $23,034. Your $580 cashback represents just 2.5% of what you actually lost.
The casino bases the percentage on your wagers rather than net losses, then caps the absolute amount to ensure high rollers never receive anywhere close to the advertised percentage of what they actually lose. Someone betting $575,840 weekly expects 30% of their losses back—that should be $150,000+ at expected loss levels. They get $580 instead.
Mell Coins
Mell Coins function as a loyalty program. Every bet you place in slots or sports betting earns points. The conversion rate depends on your currency—for example, every €15 wagered earns 1 point, $10 earns 1 point. You need minimum 1,200 points to exchange them for real money. Exchange rates vary: 1,200 points converts to €8 or $5 depending on your account currency.
Live casino games, electronic roulette, and blackjack don’t earn Mell Coins.
No Deposit Bonus
Verify your email address and receive 20 free spins for Gates of Olympus. You must have made at least one deposit since registering to qualify. The process is simple: open profile settings, enter valid email, click confirm, follow the link in the email you receive, and free spins credit within a few minutes.
The free spins carry 30x wagering with a €50 maximum win cap. You must activate them within 48 hours of being credited, then complete wagering within another 48 hours.
How Bonuses Actually Work
You activate a bonus by making the required minimum deposit. The bonus sits in a separate balance from your real money. You play normally with your real money first. Once your main account balance drops below the minimum slot bet amount, the platform starts using your bonus funds.
As you wager with bonus funds, you make progress toward the wagering requirement. After you complete the full requirement, the remaining bonus balance transfers to your main account as withdrawable cash.
Bonuses get cancelled in four situations:
- If you don’t claim an available bonus before its expiration date, it’s gone.
- If you don’t complete wagering requirements before the bonus expires (typically 7 days), you lose everything.
- If you manually activate a different bonus, the current one gets forfeited.
- If you request a withdrawal while a bonus is active, the bonus and any progress vanish.
The casino reserves the right to cancel bonuses and deny access to promotions if they detect “unfair play” or “abusive strategies” during account review. These terms are deliberately vague, giving them wide discretion. Pattern betting, bonus hunting (signing up primarily to claim bonuses), or using games with very high RTP strategically could all potentially trigger cancellation.
Payments
Deposits
The casino heavily emphasizes cryptocurrency. You can deposit using Bitcoin, USDT, USDC, Tron, TON, ETH, BNB, and Litecoin. Traditional payment methods exist but aren’t prominently featured, suggesting crypto is the preferred route. Supported fiat currencies include EUR, USD, RUB, KGS, AZN, MDL, AMD, GEL, TJS, KZT, UZS, and BYN.
Minimum deposit is €10 to qualify for most bonuses. The terms don’t specify maximum deposit limits. Minimum and maximum amounts may vary by payment method and the casino can adjust them at their sole discretion.
All payments actually process through MFI Investments Limited in Cyprus, not directly through 1Win N.V. This subsidiary acts as payment agent under agreement with 1Win. This arrangement means financial disputes involve a third entity separate from the casino operator.
Withdrawals
The terms conspicuously don’t specify daily, weekly, or monthly withdrawal limits. This absence is concerning because it means the casino can impose arbitrary limits when you attempt to cash out. Without stated limits, you have no contractual right to withdraw any particular amount per day or week.
Withdrawal processing times may vary depending on payment method, transaction value, and verification status. The platform strives to process withdrawals promptly but accepts no liability for delays caused by third-party processors or technical disruptions. This gives them significant flexibility in how quickly they actually process your request.
Identity Verification and KYC
The casino must comply with Curaçao’s National Ordinance on the Reporting of Unusual Transactions and internal AML/CTF frameworks. This means mandatory Know Your Customer procedures.
What they’ll request:
- Valid government-issued ID (passport, national ID card, or driver’s license)
- Proof of address dated within the last six months (utility bill, bank statement, tax document)
- Ownership verification for payment methods used (masked credit/debit card photos showing first six and last four digits, or e-wallet confirmations)
- Evidence of lawful source of funds
Documents must be clear, legible, and in English or accompanied by certified translation. The platform can request these documents at any time: during registration, before withdrawals, upon reaching certain transaction thresholds, or during routine compliance audits.
The casino reserves the right to delay or withhold withdrawals, restrict account activity, or suspend the account entirely until satisfactory verification is completed. They can freeze your account and associated balance, void pending or completed transactions, or permanently close the account if verification isn’t acceptable.
Enhanced Due Diligence applies to users deemed high risk under AML criteria. The frequency and depth of monitoring varies based on transactional volume, account activity, and jurisdictional risk.
You have 30 calendar days to respond to document requests. Failure to comply within this timeframe—or shorter periods where required by law or internal policy—may result in permanent account restrictions and forfeiture of funds.
Restricted Countries
You cannot access or use the platform if you’re located in or ordinarily resident in any of these territories:
Australia, Austria, Albania, Anguilla, Aruba, Afghanistan, Bahrain, Belarus, Belgium, Bulgaria, Bonaire, Brunei Darussalam, British Virgin Islands, Cambodia, Canada (Ontario Province specifically), Cayman Islands, Christmas Island, Cocos (Keeling) Islands, Croatia, Cuba, Curacao, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Gibraltar, Greece, Greenland, Guadeloupe, Heard Island and McDonald Islands, Hong Kong, Hungary, Jamaica, Japan, Jersey Island, Kazakhstan, Kuwait, Indonesia, Iran, Iraq, Ireland, Isle of Man, Israel, Italy, Latvia, Libya, Liechtenstein, Lithuania, Luxembourg, Macau, Malaysia, Mali, Malta, Martinique, Mexico, Montserrat, Myanmar, Netherlands, North Korea, Norfolk Island, Panama, Philippines, Poland, Portugal, People’s Republic of China, Puerto Rico, Qatar, Romania, Russian Federation, Saba, Saint-Barthélemy, Saint-Martin, Saudi Arabia, Serbia, Singapore, Sint Eustatius, Sint Maarten, Slovakia, Slovenia, Somalia, South Korea, South Sudan, Spain, Sudan, Sweden, Switzerland, Syria, Taiwan, Thailand, Turkey, Turks and Caicos Islands, Ukraine, United Arab Emirates, United Kingdom, United States, US Virgin Islands, Vietnam, Yemen, and Zimbabwe.
This list covers essentially every well-regulated gambling market on the planet. The casino can add territories to this list at any time without notice. You’re responsible for checking current restrictions. The availability of the platform in any specific language, currency, or country does not constitute an offer or invitation to access services if such access is prohibited by local laws.
If the casino becomes aware you’re resident in a country where the website is considered illegal, they have the right to close your account and refund any remaining balance after deducting winnings credited after your most recent deposit.
Certain game providers may also block access based on your jurisdiction regardless of your registration status on the platform. Some games simply won’t load if you’re in the wrong place.

Is Mellstroy Casino a Scam?
Mellstroy Casino official delivers a massive game library and crypto-friendly payment structure on a Curaçao-licensed platform. The 9,000+ games from 50+ providers is genuinely impressive.
On the other hand, the terms give the operator enormous discretion to delay withdrawals, cancel bonuses, freeze accounts, and confiscate funds. The vague language around “fraudulent activity,” “suspicious behavior,” and “insufficient gaming activity” creates situations where they can accuse you of wrongdoing without clear standards.
As detailed in the “Who’s Behind This” section above, both Mellstroy and 1Win have documented histories of financial issues.
If you’re in a properly regulated gambling market, you have safer options with stronger oversight, clearer rules, and genuine recourse if something goes wrong. If you’re not in a regulated market, this casino comes with substantial risks you need to understand fully before depositing any money.
