Oyine N.V. Casinos
Oyine N.V. is a Curaçao-licensed iGaming company best known for operating Bitsler Casino. Active since 2015, Bitsler supports more than 25 cryptocurrencies and combines flexible crypto payments with slots, live casino games, in-house titles, and sports betting.
We tested the Oyine N.V. casino across payments, withdrawals, games, bonuses, mobile usability, licensing, account security, and customer support. This guide explains how Bitsler performs and what players should know about Oyine N.V. casinos before registering.
What is Oyine N.V.?
Oyine N.V. is a Curaçao-based iGaming company and the operator behind Bitsler Casino. Unlike casino groups that manage several brands, Oyine N.V. is primarily associated with Bitsler, making its operation more focused.
The company’s platform combines cryptocurrency gambling with a broader casino and sportsbook offering. Players can access third-party slots and live dealer games alongside Bitsler Originals, provably fair titles, sports betting, crypto payments, bonuses, and loyalty rewards.
Oyine N.V. operates internationally under a Curaçao licence. Bitsler’s terms, payment rules, restricted countries, KYC requirements, and responsible gambling controls therefore determine the experience at casinos owned by Oyine N.V.
Best Oyine N.V. Casino: Bitsler
Bitsler: Best for Crypto Payments and Provably Fair Games
Bitsler is the main casino owned by Oyine N.V. and the only brand currently featured in our Oyine N.V. casino ranking. It combines a crypto-first cashier with more than 3,200 slots, table games, live dealer titles, sports betting, and in-house games that use provably fair verification.

The cashier is its strongest feature. Bitsler supports 29 cryptocurrencies, including Bitcoin, Ethereum, Litecoin, Dogecoin, Tether, Solana, and XRP. Deposits carry no casino fee, while withdrawal charges, limits, and processing times depend on the selected coin and network.
The welcome package offers 200% up to $2,000 plus 500 free spins. However, the bonus terms should be checked before claiming, and the live casino and table game sections are smaller than those at higher-rated alternatives. Bitsler is therefore better suited to crypto players who prioritize coin choice, in-house games, and sportsbook access over a deep live casino lobby.
- Big-win Jackpot and Megaways games
- 29 instant crypto options with no fees
- Sports betting covering many sports
- Numerous well-known providers
- Live chat and FAQ
- Limited selection of live games

Are Oyine N.V. Casinos Legal and Legit?
Yes, Bitsler is a legitimate offshore casino operated by Oyine N.V. The Curaçao Gaming Authority’s license registry lists Oyine N.V. under B2C license OGL/2024/930/0387, with company number 144430 and an indefinite status.
The licence permits Oyine N.V. to offer online gambling under Curaçao’s regulatory framework. It does not make Bitsler locally licensed in every country where the site is available, so players must still follow the gambling laws and age requirements in their own jurisdiction.
The license also means Oyine N.V. must follow regulatory requirements covering player verification, anti-money-laundering checks, transaction monitoring, responsible gambling, and complaint handling. KYC may therefore be requested when account or payment activity requires additional review.
Are Oyine N.V. Casinos Safe?
Bitsler uses the main account and payment protections expected from a licensed crypto casino. These include SSL encryption, optional two-factor authentication, email verification for withdrawals, login alerts, provably fair games, and responsible gambling controls. These measures reduce common security risks, although no online casino can guarantee complete protection.
Here is what we found when checking Bitsler:
- SSL encryption: Bitsler states that encrypted connections protect information exchanged between the website and the player’s device.
- Two-factor authentication: Players can secure logins and selected account actions with a changing six-digit code.
- Login verification: Email alerts can be enabled for access from an unknown browser or device, allowing the player to approve or reject the login.
- Withdrawal protection: A verified email address is required before funds can be withdrawn, a standard security check used before instant payouts at Bitcoin casinos are released.
- Provably fair games: Results from Bitsler’s in-house games can be checked using the platform’s verification system.
- Fund storage: Bitsler states that most casino funds are held offline in cold storage, with hot wallets used for daily transactions.
- Responsible gambling controls: Players can use temporary suspension, permanent self-exclusion, and other account limits when they need to restrict their play.
Why Choose Oyine N.V. Casinos?
Players choose Oyine N.V. casinos mainly for Bitsler’s crypto-first setup, which combines broad coin support, original games, sports betting, and ongoing rewards. The platform also works smoothly across desktop and mobile, with casino games and sports available through one account.
- Broad crypto support: Bitsler accepts 29 cryptocurrencies, including BTC, ETH, USDT, LTC, DOGE, XRP, and SOL.
- Exclusive in-house games: Bitsler Originals provide casino games developed specifically for the platform.
- Provably fair results: Players can verify outcomes from supported in-house games using the casino’s fairness system.
- Quick registration: Creating an account requires only basic details, although KYC may still be requested later.
- Casino and sportsbook access: Players can use the same account and balance for gambling games and sports betting.
- Fast crypto payments: Deposits carry no casino fee, while withdrawal speed and charges depend on the selected network.
- Recurring promotions: VIP coupons, crypto bonuses, wagering contests, races, and rakeback reward regular activity.
- BTSLR cryptocurrency: Bitsler uses its own cryptocurrency, BTSLR, within its rewards and platform ecosystem.
- Mobile-friendly play: The casino, sportsbook, cashier, and account settings are accessible through a mobile browser.
What Are the Possible Downsides of Oyine N.V. Casinos?
Oyine N.V. operates Bitsler as its only known casino brand, so the company offers less variety than operators with several sites. The main drawbacks involve limited regional access, possible verification, crypto-only banking, and a smaller casino lobby than higher-rated alternatives.
Only One Casino Brand
Bitsler appears to be the only casino owned by Oyine N.V. Players who dislike its interface, bonus rules, game selection, or account policies cannot choose another brand under the same operator.
Restricted in Several Major Markets
Bitsler does not accept players from the United States, United Kingdom, Australia, Germany, France, Spain, Sweden, and several other regulated or prohibited markets. This makes Oyine N.V. less widely available than its international positioning may suggest.
KYC May Still Be Required
Oyine N.V. does not operate a completely no KYC crypto casino. Registration requires limited personal information, but identity, address, or payment verification may still be requested before withdrawals or when account activity triggers a review.
Smaller Live Casino Selection
Bitsler offers more than 3,200 slots but only around 30 live games and 40 table games. Players mainly interested in live blackjack, roulette, baccarat, or game shows will find considerably larger selections at some alternatives.
Bonuses and Games Can Have Regional Restrictions
Welcome offers, free spins, and third-party games are not always available in every accepted country. Providers such as NetEnt apply their own territory restrictions, which can remove specific games even when Bitsler itself accepts the player’s location.
What Countries Does Oyine N.V. Accept Players From?
Because Bitsler is the only known Oyine N.V. casino, its country policy determines where the operator accepts players. Bitsler is available in countries not listed as restricted, provided online gambling is permitted under the player’s local laws.
Examples of countries not named in Bitsler’s restricted list include Canada, Brazil, Finland, Norway, New Zealand, Japan, and South Africa. Availability can still vary by payment method, bonus, and software provider.
What Are the Most Popular Games at Oyine N.V. Casinos?
Bitsler, the only known Oyine N.V. casino, offers slots, live dealer games, table games, and exclusive crypto titles.
Slots
Slots form the largest part of the lobby, covering classic reels, video slots, jackpots, Megaways games, and bonus-buy titles. Most can also be tested in demo mode.
Bitsler Originals
Bitsler offers exclusive games such as Plinko, Mines, Dice, Twist, Fruitsler, Baccarat, Roulette, and Ultimate Poker. These titles use provably fair technology, allowing players to verify individual results.
Live Casino Games
The live casino includes blackjack, roulette, baccarat, poker variants, and game shows streamed from professional studios. Evolution, Pragmatic Play, and Playtech supply many of these tables.
Table Games
Players can choose from digital blackjack, roulette, baccarat, poker, Dragon Tiger, and Sic Bo. Bitsler also provides its own versions of several traditional table games.
Crash and Instant Games
Fast games such as crash, mines, dice, and Plinko use short rounds and simple controls. Several are available as Bitsler Originals with adjustable risk settings.

Bitsler combines games from established software studios with its own provably fair titles. Popular providers include:

Welcome Offer

No Deposit Bonus
New accounts can claim 0.02 USDT through customer support without depositing. The balance can be used on any game that accepts the available bet size.
Rakeback
Bronze-level players receive standard 5% rakeback on the house edge from eligible bets. The accumulated reward can be claimed every two minutes, although sports, baccarat, and selected third-party games do not qualify.

Oyine N.V. vs Other Curaçao Companies
This table compares casinos owned by Oyine N.V. with the Curaçao companies behind BetFury and Stake, focusing on crypto support, provably fair games, platform strengths, and their main limitations.
| Feature | Oyine N.V. | Universe B Games B.V. | Medium Rare N.V. |
|---|---|---|---|
| Example Casino | Bitsler | BetFury | Stake |
| Main Focus | Crypto casino, Originals, and sportsbook | Crypto casino with extensive rewards | Crypto-first casino and sportsbook |
| Crypto Support | 29 cryptocurrencies | 34+ cryptocurrencies | 21 cryptocurrencies |
| Provably Fair Games | Strong focus through Bitsler Originals | Available through BetFury Originals | Major focus through Stake Originals |
| Standout Strength | Broad coin support and verifiable in-house games | Large game library and recurring crypto rewards | Established VIP program and deep sportsbook |
| Main Downside | Smaller live casino library and only one known brand | Bonus and reward systems can be complex | Fewer supported coins than Bitsler or BetFury |

Responsible Gambling Tools at Casinos Owned by Oyine N.V.
Oyine N.V. currently offers self-exclusion but does not provide self-service deposit, loss, wager, or session limits. This is weaker than expected from a modern Curaçao-licensed casino, as many operators under the same licensing system provide several adjustable limits directly in the account dashboard.
Self-exclusion requires email confirmation and begins with a 24-hour restriction. Players then receive another email to choose the full exclusion period. During the restriction, all gambling products and remaining balances are inaccessible, and the exclusion cannot be cancelled early.
Without adjustable limits, players need to track their crypto deposits, wagers, losses, and playing time independently. Anyone who finds this difficult should use self-exclusion early or choose a casino with stronger account-level controls.
Conclusion
With Bitsler as its only known casino brand, Oyine N.V. runs a more focused operation than most multi-brand Curaçao companies. Its strengths are broad support for 29 cryptocurrencies, provably fair Originals, sports betting, fast crypto payments, and an XP-based rewards system with rakeback and cash coupons.
The weaknesses are just as specific. Oyine N.V. offers a smaller live casino library, limited traditional banking, possible KYC checks, and access restrictions across several major markets. Responsible gambling controls are also weaker than expected from a Curaçao-licensed casino, with self-exclusion available but no adjustable deposit, loss, wager, or session limits.
Overall, casinos owned by Oyine N.V. are best suited to crypto players who value coin choice and verifiable in-house games. Players who want deeper live casino coverage, multiple brands, or stronger account controls should compare Bitsler with BetFury, Stake, and the other best crypto casino sites.
