| Full Legal Name | Sefiarray B.V. (Curaçao registration #155219) |
| Parent Company | Dumelita Ltd (Cyprus) |
| Primary Licence(s) | Curaçao — Antillephone #8048/JAZ (Casino Guru currently lists no valid licence) |
| Active Casino Brands | 4 (Betti, Casinoways, Betmac, TrustStake) |
| Casino Guru Safety Index | 6.2/10 (Below Average) |

Sefiarray B.V. operates from Fransche Bloemweg 4, Willemstad, Curaçao, with Dumelita Ltd providing management, payment processing, and support services from Paphos, Cyprus. This dual-jurisdiction structure is common among Curaçao-licensed operators but makes corporate transparency harder for players to assess. Unlike operators backed by established groups such as Bet365 sister brands or Coral's parent Entain, Sefiarray B.V. has no publicly disclosed beneficial ownership, which contrasts sharply with the disclosure requirements imposed on UKGC-licensed competitors. The network's rapid growth from a single brand in 2022 to four by early 2025 signals commercial ambition, though Casino Guru's decision to list the casino as having no valid licence raises questions about the current regulatory standing that players should investigate before depositing.
| Brand | Our Rating | Welcome Bonus | Payout Speed (Crypto) | Top Feature |

Bonuses are subject to change — always verify the latest terms directly on each operator's website before depositing.

Casinoways launched in 2024 as Sefiarray B.V.'s second brand, entering the market through affiliate channels rather than a public launch. The site adopts a cleaner, minimalist aesthetic with a white-and-blue palette that targets casual-to-mid-stakes players who prefer function over flash.
The site shares the same Curaçao Antillephone #8048/JAZ licence as Betti Casino. The game library draws from Play'n GO, NetEnt, Pragmatic Play, Red Tiger Gaming, and Evolution Gaming, with roughly 1,000+ titles and substantial overlap with Betti Casino's catalogue.
Casinoways offers a 100% deposit match up to €500 with 35x wagering — notably lower than Betti Casino's 45x. The minimum deposit is €20, and free spins are included. For bonus-focused players, this lower playthrough alone may justify registering here instead. Slots contribute 100% toward wagering, while table and live games contribute 10%.
Banking mirrors the network: Visa, MasterCard, bank wire, and crypto. The same €2,000/€6,000/€15,000 daily/weekly/monthly withdrawal caps apply. Crypto processes within an hour; bank transfers take 24–72 hours. The €100 minimum withdrawal matches Betti Casino — high compared to competitors like Rolletto sister sites at €20. Casinoways lacks Betti Casino's Karma Loyalty Shop, making it better for deposit-and-play sessions than loyalty grinding.

Betmac arrived in January 2025 as the newest Sefiarray B.V. property, distinguishing itself with a comic-book superhero theme that stands apart from the network's otherwise subdued design language. This is a casino-only property with no sportsbook section, which narrows appeal but sharpens focus — the entire interface is dedicated to casino content, making game discovery faster than on Betti Casino's multi-product layout.
The game library exceeds 2,000 titles from providers including Play'n GO, Hacksaw Gaming, Evoplay, and Playson. Popular titles like Book of Dead, Legacy of Egypt, and Crystal Cavern headline the slots section. The Curaçao licensing framework carries over from the parent network.
Betmac's welcome bonus offers a 100% match up to €525 plus 100 free spins at 35x wagering. The minimum qualifying deposit is €20, and the bonus must be cleared within 7 days. The non-sticky structure means real money is wagered first. Free spins credit across two days, with the second batch arriving 24 hours after the first deposit.
The loyalty programme uses an XP coin system with a bonus shop for cash bonuses, free spins, and physical prizes — mirroring Betti Casino's Karma concept. Banking and withdrawal limits are identical to the rest of the network. Player forum reports suggest Betmac processes crypto withdrawals quickly, though the sample size remains small given the brand's youth. Betmac suits players who want a casino-only environment without sportsbook distractions and who respond to the more playful visual identity.

|---|---|
| Site Identity | Bold comic-book superhero theme — the loudest design in the Sefiarray network |
| What Sets It Apart | Casino-only focus with no sportsbook; XP coin loyalty shop |
| Game Selection | 2,000+ titles from Play'n GO, Hacksaw Gaming, Evoplay, Playson |
| Best Bonus Feature | Non-sticky 100% match with 35x wagering |

| Ideal Player | Slots-focused players who want a dedicated casino environment with loyalty rewards |

TrustStake rounds out the confirmed Sefiarray B.V. network as a crypto-forward casino that leans harder into digital currency banking than its siblings. The design aesthetic is dark-themed and modern, appealing to players comfortable navigating crypto exchanges and blockchain wallets. The same Curaçao licensing and shared backend infrastructure carry over from the parent network.
The game library draws from the same provider pool as Betti Casino — Play'n GO, Pragmatic Play, Evolution Gaming — with a library size comparable to Casinoways at around 1,000 titles. Welcome bonus terms have varied since launch and are less clearly documented than at other Sefiarray B.V. properties, though wagering requirements fall in the 35x range consistent with the network pattern.
Banking is TrustStake's primary differentiator. While all Sefiarray B.V. brands accept crypto, TrustStake foregrounds these options in its cashier layout. Withdrawal caps mirror the €2,000/€6,000/€15,000 structure, and crypto cashouts process within the standard hour. The promotional calendar is sparse compared to Betti Casino's Karma Loyalty Shop. For players comparing across operators, Velobet sister sites and Cosmobet sister sites offer similar crypto-friendly Curaçao-licensed alternatives with deeper feature sets.

MyStake operates under OnyxioN B.V. with a separate Curaçao licence. Launched in 2019, it has grown into one of the largest independent Curaçao-licensed casino and sportsbook platforms, with over 6,000 games from 90+ providers, a full sportsbook, and exclusive mini-games with provably fair mechanics. Where Sefiarray B.V. operates four brands with overlapping catalogues, MyStake concentrates everything into a single, deeply stocked property.
Casino Guru awards MyStake a Safety Index of 9.6 out of 10, contrasting sharply with Betti Casino's 6.2. Trustpilot reinforces this gap: MyStake holds 4.2 out of 5 from over 24,000 reviews versus Betti Casino's 2.4 from roughly 200 reviews.
The welcome bonus offers two tiers: 150% up to €200 for deposits between €20 and €200, or 100% up to €1,000 for larger deposits. Wagering sits at 30x — lower than both Betti Casino's 45x and the network's 35x. Banking extends to 20+ methods including crypto and e-wallets. Responsible gambling tools include deposit limits, loss limits, session time-outs, and self-exclusion for up to five years, though these require contacting support rather than self-service.
MyStake is the recommendation for players who find Betti Casino's game library limited or who want reassurance from a significantly higher safety rating.

Rolletto operates under Santeda International B.V. with a Curaçao licence, offering a combined casino and sportsbook that covers similar ground to Betti Casino but with a deeper sports betting product and broader banking.
The casino section features Pragmatic Play, Play'n GO, Evolution Gaming, and BGaming among others, with a library exceeding 3,000 games. The sportsbook covers major football leagues, tennis, basketball, and esports with competitive odds — a more balanced dual-product experience than Betti Casino's casino-first layout.
The welcome bonus offers a 100% match up to €500 at 35x wagering with a €20 minimum deposit. Banking is broader than the Sefiarray B.V. network: alongside card and crypto, Rolletto supports e-wallet services that Betti Casino lacks entirely. Withdrawals start from €20 — significantly lower than Betti Casino's €100 minimum. Responsible gambling tools include deposit limits, cooling-off periods, and self-exclusion.

Betti Casino remains the flagship of the Sefiarray B.V. network by virtue of being the first brand launched and the one with the most developed loyalty infrastructure. The Karma Loyalty Shop and Instant Karma Cash Drops (random prizes between €5 and €1,000 with zero wagering) give Betti Casino an engagement edge over Casinoways, which lacks any meaningful loyalty programme, and TrustStake, which barely promotes its promotional calendar. Betmac's XP coin system comes closest to replicating Betti Casino's loyalty mechanics, but the brand is too new to have proven its long-term reward consistency. Players evaluating loyalty programmes from Curaçao-licensed operators may also want to explore Cosmobet sister sites for a broader comparison.
On bonus terms, however, Betti Casino sits at the bottom of its own network. The 45x wagering requirement on the welcome bonus is the highest among all Sefiarray B.V. properties, where both Casinoways and Betmac offer 35x. For a player depositing €100 at Betti Casino and receiving a 150% match of €150, the total wagering obligation reaches €6,750 — compared to €5,250 at Casinoways for a €100 deposit with a 100% match bonus. The mathematical advantage of the sister sites is clear for bonus-motivated players.
Game library breadth is roughly consistent across the network, with all brands drawing from the same provider integrations. Betti Casino and Betmac offer the widest selections at around 2,000 titles each, while Casinoways and TrustStake sit closer to 1,000. Withdrawal speeds are identical: crypto processes within an hour, bank transfers take 24–72 hours, and the €100 minimum withdrawal applies universally. The sportsbook product is available at Betti Casino and TrustStake but absent from Betmac and less prominent at Casinoways.
The Sefiarray B.V. network expanded rapidly through 2024 and 2025, adding Casinoways in 2024, Betmac in January 2025, and TrustStake within the same period. No new brands have been confirmed for 2026 at the time of writing, which may indicate a shift from expansion to consolidation. The most significant development is Casino Guru's decision to list Betti Casino as having no valid licence — a status change that coincides with the broader Curaçao regulatory transition from Antillephone-issued licences to the new Curaçao Gaming Control Board (GCB) framework. Whether Sefiarray B.V. has secured or is in the process of obtaining a GCB licence remains unclear from publicly available information, and players should verify the current licensing status directly before creating an account. The Gambling Commission register provides a transparency benchmark that Curaçao's evolving regulatory framework has yet to match.
| Payment Method | Min Deposit | Max Deposit | Withdrawal Time | Fees |

| Visa / MasterCard | €10–€20 | €5,000 | Not available for withdrawal | None stated |
| Bank Wire Transfer | €20 | €5,000 | 24–72 hours | None stated |
| Bitcoin | €10 | €5,000 | Under 1 hour | Network fees only |

Cryptocurrency is the clear winner for withdrawal speed, with most crypto cashouts settling within minutes once approved. Bank transfers remain slowest at 24–72 hours. The €100 minimum withdrawal is a genuine drawback — competitors like Rolletto and MyStake sister sites allow cashouts from €20. The €2,000 daily cap limits high-volume players, with €15,000 maximum per month. Betti Casino does not support e-wallet withdrawals through PayPal, Skrill, or Neteller — a significant banking gap.
| Site | Top 5 Providers | Approx. Game Count | Live Dealer Available |
|---|---|---|---|
| Betti Casino | Play'n GO, Evolution, Pragmatic Play, Hacksaw Gaming, Red Tiger | 2,000+ | Yes |
| Casinoways | Play'n GO, NetEnt, Pragmatic Play, Red Tiger, Evolution | 1,000+ | Yes |
| Betmac | Play'n GO, Hacksaw Gaming, Evoplay, Playson, Pragmatic Play | 2,000+ | Yes |
| TrustStake | Play'n GO, Pragmatic Play, Evolution, Red Tiger, Quickspin | 1,000+ | Yes |
| MyStake | Pragmatic Play, Evolution, Play'n GO, Hacksaw, BGaming | 6,000+ | Yes |
Provider overlap across the Sefiarray B.V. network is substantial: Play'n GO and Pragmatic Play appear at every property, and Evolution Gaming powers all live dealer sections. Betti Casino and Betmac have the deepest catalogues, while Casinoways and TrustStake lag behind. MyStake operates on an entirely different scale with exclusive mini-games and provably fair titles that no Sefiarray B.V. brand matches.
The live casino across the Sefiarray B.V. network is powered by Evolution Gaming, Pragmatic Play Live, and Ezugi. Betti Casino offers live blackjack, roulette, baccarat, and game show titles. Table limits accommodate casual through mid-stakes play, though the network does not cater to genuine high-roller action in the way that operators behind William Hill sister sites do through dedicated VIP tables.
None of the Sefiarray B.V. brands offer dedicated mobile apps. All four properties rely on browser-based mobile optimisation, which functions adequately on modern devices with loading times under 1.5 seconds on the homepage.
The loyalty landscape is uneven. Betti Casino leads with its Karma Loyalty Shop — points redeemable for bonuses, free spins, and physical prizes including Apple Watches — plus Instant Karma Cash Drops (€5–€1,000, zero wagering). Betmac's XP coin system offers comparable redemption mechanics. Casinoways and TrustStake offer minimal loyalty infrastructure.
Betti Casino's licensing situation requires careful assessment. Sefiarray B.V. originally operated under Antillephone licence #8048/JAZ in Curaçao. However, Casino Guru currently lists Betti Casino as having no valid licence, which may reflect the ongoing transition from Antillephone permits to the new Curaçao Gaming Control Board (GCB) framework. Players should independently verify the current licence status before depositing.
The site employs 256-bit SSL encryption authenticated by DigiCert, and all games use certified random number generators. KYC verification is required before withdrawals — completing this promptly after registration is strongly recommended, as delayed verification is the most common complaint trigger for this operator.
Betti Casino's responsible gambling tools include daily, weekly, and monthly deposit limits; time-out options from 24 hours to one month; reality check notifications; and self-exclusion available through customer support. Third-party blocking tools like BetBlocker can be installed independently. However, the Casino Guru complaint record includes a case where self-imposed deposit limits were reportedly removed without adequate checks. For a UKGC-licensed comparison with stricter responsible gambling enforcement, our All British Casino review documents a domestically regulated alternative.
| Site | Licence Body | Licence No. | Responsible Gambling Tools | RNG Testing |
|---|---|---|---|---|
| Betti Casino | Curaçao (Antillephone) | #8048/JAZ (validity disputed) | Deposit limits, time-out, self-exclusion, reality checks | Certified RNG |
| Casinoways | Curaçao (Antillephone) | #8048/JAZ | Deposit limits, time-out, self-exclusion | Certified RNG |
| Betmac | Curaçao (Antillephone) | #8048/JAZ | Deposit limits, time-out, self-exclusion | Certified RNG |
| TrustStake | Curaçao (Antillephone) | #8048/JAZ | Deposit limits, time-out, self-exclusion | Certified RNG |
| MyStake | Curaçao (GCB) | OnyxioN B.V. licence | Deposit limits, loss limits, session time-outs, self-exclusion (up to 5 years) | Certified RNG, provably fair on originals |

Casino Guru records 5 formal complaints against Betti Casino with 3,870 black points, pushing the Safety Index to 6.2 (Below Average). Complaint themes include delayed withdrawals, failed crypto deposit refunds, and one case where a player with a gambling addiction reported the casino kept their account open despite multiple closure requests and offered bonuses to discourage departure. That complaint was marked "unresolved" after the casino failed to respond to Casino Guru's investigation.
| Source | What Players Praise | What Players Criticise |
|---|---|---|
| Trustpilot (200+ reviews) | Modern interface, game variety, functional live chat | Withdrawal delays, aggressive verification, pending requests without explanation |
| Reddit (/r/gambling) | Crypto payout speeds, loyalty shop rewards | High wagering, €100 min withdrawal, unclear licensing |
| Casino Guru (Safety Index 6.2) | 24/7 live chat rated "fast and professional" | Unresolved account closure complaint, 3,870 black points, licence concerns |
The Trustpilot 2.4 out of 5 rating reflects a polarised base. Positive reviews highlight smooth crypto withdrawals; negative reviews cluster around verification delays and large withdrawal requests stalling without communication. Our Coral Casino review covers a UKGC-regulated operator with a contrasting complaint resolution track record for comparison.
Betti Casino's headline welcome bonus offers a 150% deposit match up to €750 plus 150 free spins at 45x wagering on the bonus amount — the most demanding playthrough in the Sefiarray B.V. network. A worked example: depositing €100 triggers a €150 bonus for a total balance of €250. The wagering requirement applies to the bonus only (non-sticky), so the player must place €6,750 in qualifying bets (€150 x 45) within 7 days. Slots contribute 100%, while live and table games contribute 10% — a roulette player would effectively need €67,500 in table play. Maximum bet during wagering is €5, and bonus winnings cap at €5,000.
Free spins distribute at 30 per day over 5 days, expire within 24 hours of each batch, carry 35x wagering, and cap winnings at €100. Compare this to Casinoways where a €100 deposit generates €100 bonus at 35x, requiring only €3,500 in qualifying bets. No Sefiarray B.V. property currently offers a no-deposit bonus. For a UKGC-licensed benchmark with different bonus structures, our Genting Casino review details an alternative welcome offer worth comparing.
The most conspicuous gap is e-wallet support. None of the four brands accept PayPal, Skrill, Neteller, or Apple Pay, eliminating the most convenient traditional banking methods for many players. Competitors like 888 Casino and All British Casino offer multiple e-wallet options as standard.
The €100 minimum withdrawal is unusually high. Players with smaller balances cannot cash out until they accumulate enough — a restriction that disproportionately affects casual players. Phone support is absent entirely, with service limited to live chat and email. The licensing transparency gap is arguably the most serious concern: Casino Guru listing "no valid licence" creates genuine uncertainty that Sefiarray B.V. has not publicly addressed. Published RTP data is not readily accessible, and there is no information about fund segregation or a named ADR provider, leaving players with limited formal recourse beyond third-party mediation.
For players committed to the Sefiarray B.V. network, Casinoways has the best bonus mathematics at 35x wagering, Betti Casino itself has the richest loyalty programme, Betmac suits slots-only players who want no sportsbook clutter, and TrustStake serves crypto-native players. For those willing to step outside the network, MyStake represents the strongest alternative with its 9.6 Safety Index, 6,000+ games, and 30x wagering. Rolletto offers a compelling middle ground for dual casino-and-sports players with lower withdrawal minimums.
The Sefiarray B.V. network is a compact operation with four functionally similar brands differentiated by bonus terms, visual design, and ancillary features. Betti Casino leads through its Karma Loyalty Shop, but the 45x wagering requirement is the least competitive in the network. Casinoways and Betmac offer better bonus mathematics at 35x.
The most important consideration is the licensing ambiguity. Casino Guru listing Betti Casino as having no valid licence raises genuine questions that Sefiarray B.V. has not publicly addressed. Players valuing licensing certainty will find better-documented alternatives at MyStake (Casino Guru 9.6/10) or Rolletto.
If you register at any Sefiarray B.V. property, complete your KYC verification immediately after registration — upload photo ID, proof of address, and payment method confirmation before placing your first bet. The most common complaint pattern involves withdrawal delays caused by incomplete verification, and front-loading this process eliminates the most predictable friction point.
