Mellstroy Casino is an influencer-branded online casino built on the 1Win platform and launched in 2024. The casino is operated by 1WIN N.V. (registration number 147039) under a Curaçao gaming licence (8048/JAZ2018-040), with parent company MFI Investments Limited registered in Cyprus. All payments process through MFI Investments Limited as a separate payment agent rather than directly through the casino operator. The platform is branded around Mellstroy, the online alias of Andrey Burim, a Belarusian-Russian streamer known for extreme content. The casino offers 9,000-plus games from over 50 providers and a welcome package of 550% across four deposits plus 400 free spins. Before registering, players should be fully aware of the serious concerns documented below.
Important Warnings
The individual behind the Mellstroy brand, Andrey Burim, gained notoriety in October 2020 when he violently assaulted a model on a live stream watched by approximately 720,000 viewers, resulting in serious injuries including a broken jaw. He is currently banned from YouTube, Twitch and other major platforms. Independent sources document that Mellstroy has failed to honour financial commitments totalling over $14 million across at least seven separate documented cases. A financial dispute between Mellstroy and 1Win reportedly involved approximately $8.4 million owed to 1Win, which was resolved before the casino launch. The 1Win platform has received numerous player complaints across multiple review channels describing withdrawal delays, frozen accounts and unresolved payment disputes. The Curaçao Gaming Authority explicitly states that it does not handle individual player complaints. The casino’s terms contain deliberately vague language around terms such as fraudulent activity, suspicious behaviour and insufficient gaming activity, giving the operator wide discretion to delay withdrawals, cancel bonuses, freeze accounts and confiscate funds without clear standards. No daily, weekly or monthly withdrawal limits are stated in the terms, meaning the casino can impose arbitrary limits when players attempt to withdraw. The restricted country list covers essentially every well-regulated gambling market including the entire EU, UK, US, Canada, Australia and dozens of others. Players in regulated markets have access to safer, more thoroughly regulated alternatives with genuine player complaint recourse.
Welcome Bonus
Mellstroy Casino offers a four-deposit welcome package totalling 550% up to €440 plus 400 free spins. The first deposit gives 100% up to €110 plus 100 free spins for The Dog House Megaways, minimum deposit €10. The second deposit gives 125% up to €110 plus 100 free spins for Gates of Olympus 1000. The third deposit gives 150% up to €110 plus 100 free spins for Big Bass Bonanza. The fourth deposit gives 175% up to €110 plus 100 free spins for Zeus vs Hades Gods of War. Each bonus must be activated within 72 hours of deposit or it expires. Once activated, wagering must be completed within 7 days or the bonus and all winnings are forfeited. The percentage bonus carries a 25x wagering requirement on the bonus amount. Free spins carry 30x wagering on winnings, capped at a maximum of €50 in winnings regardless of actual results. Only one bonus can be active at a time. Activating a new bonus while one is already running forfeits the current bonus and all progress. Bonus funds only apply in a designated Bonus Wagering game category. A 20 free spins no-deposit offer is available on Gates of Olympus for players who verify their email and have made at least one prior deposit, subject to 30x wagering and a €50 maximum win cap. A cashback promotion returns a percentage of net slot losses weekly, though the structure is built on total wagers rather than actual losses, and the absolute cap means high-volume players receive a fraction of the advertised percentage.
Payments
The casino emphasises cryptocurrency deposits including Bitcoin, USDT, USDC, Tron, TON, Ethereum, BNB and Litecoin. Fiat currencies supported include EUR, USD, RUB and others primarily associated with CIS markets. Minimum deposit is €10. No daily, weekly or monthly withdrawal limits are stated in the published terms. Withdrawal processing times are not guaranteed and the casino accepts no liability for delays caused by third-party processors. All payments process through MFI Investments Limited in Cyprus rather than directly through 1WIN N.V., meaning financial disputes involve a third entity separate from the casino operator.
Games
The game library at Mellstroy Casino covers over 9,000 titles from more than 50 providers including Pragmatic Play, BGaming, Evolution Gaming, Hacksaw Gaming, Nolimit City, PG Soft, Endorphina, Playtech, Evoplay, Playson and others. Categories include slots, roulette, live casino, blackjack, bonus buy titles, crash games and Mell Originals — a set of 10 proprietary instant games including Crash, Mines, Dice, Penalty, Coinflip, Poker, Double, Keno, Blackjack and Hilo. The live casino is powered primarily by Evolution Gaming and Pragmatic Play Live, covering standard and game show formats including Crazy Time, Monopoly Live, Lightning Roulette and others. Progressive jackpots are available with a combined pool reported at over $11 million.
Support and Responsible Gambling
Email support is available at [email protected]. The casino operates under the Curaçao Gaming Authority licence. Players should be aware that the Curaçao Gaming Authority explicitly does not handle individual player complaints, meaning there is no formal regulatory complaint mechanism available to players who experience disputes.
Pros and Cons
Pros:
- 9,000-plus games from 50-plus providers including Evolution Gaming and Pragmatic Play
- 550% four-deposit welcome package up to €440 plus 400 free spins

Cons:
- Branded around an individual with documented violent conduct and over $14 million in unmet financial obligations
- 1Win platform has numerous documented player complaints about withdrawals and frozen accounts
- Curaçao licence offers minimal formal player protection with no individual complaint handling
- No stated withdrawal limits — operator can impose arbitrary caps
- Vague terms giving operator wide discretion to cancel bonuses and confiscate funds
- Restricted in virtually every well-regulated gambling market globally

Final Verdict
Mellstroy Casino operates on the 1Win platform under a Curaçao licence with a large game catalogue and substantial welcome package. However, the combination of serious documented concerns — the conduct and financial history of the brand figurehead, the 1Win platform’s player complaint record, the absence of stated withdrawal limits, vague forfeiture terms and the effective exclusion of all well-regulated markets — means this platform carries substantial risks that players should weigh carefully before depositing. Players in regulated markets have access to platforms with stronger oversight, clearer rules and genuine complaint recourse. Players outside regulated markets who choose to proceed should read all terms in full, complete identity verification before depositing significant funds, and use cryptocurrency to retain transaction records.
