Winum Casino Review

Reviewed & updated July 2026 by the Winum Guide team. 18+. Play responsibly.

Winum Casino is a crypto-focused online casino operated by Galaxy Byte Lab SRL (registered in Costa Rica) under an Anjouan Gaming Board licence, ALSI-202508040-FI2, established around 2020. It advertises a very large library — its own site headlines 10,000+ games — alongside Bitcoin, Ethereum, Litecoin and USDT payments and a 500% welcome bonus, which on paper looks generous. But the safety picture is the concern: independent reviewer Casino Guru currently scores Winum's Safety Index at just 3.8 out of 10, placing it in the 'Low' category, and Casino Guru explicitly recommends that players steer clear and choose a casino with a higher score. It also logs several player complaints — around six in its database — involving withheld winnings, account closures and delayed payments, and notes a high value of withheld winnings relative to the casino's small size. The 500% bonus, meanwhile, comes with wagering and limits we could not confirm as a single consistent set of terms. Taken together — a 'Low' safety rating, complaints about withheld winnings, and a headline bonus whose terms need verifying — our recommendation matches Casino Guru's: this is not a casino we'd suggest choosing over a better-rated, more consistently documented alternative.

Licence & operator

Winum Casino is operated by Galaxy Byte Lab Sociedad de Responsabilidad Limitada, registered in Costa Rica — a jurisdiction that registers companies but does not itself issue gambling licences. The casino's gambling licence comes from the Anjouan Gaming Board (Union of Comoros), number ALSI-202508040-FI2, which the brand displays in its own site footer; this is a valid, real offshore licence format, not an absence of licensing. What matters is the type of licence: Anjouan is an entry-level offshore regulator with limited oversight, offering considerably less player-protection and dispute-resolution infrastructure than a major body such as the UK Gambling Commission or the Malta Gaming Authority. That gap matters more here because of Casino Guru's independent Safety Index for Winum — 3.8 out of 10, category 'Low', with Casino Guru's own guidance recommending players steer clear. Several logged complaints about withheld winnings, account closures and delayed payments reinforce that caution.

Payments & withdrawals

Winum is genuinely crypto-forward: we confirmed Bitcoin, Ethereum, Litecoin and USDT, alongside cards and e-wallets such as Visa, Mastercard, Skrill, Neteller and Trustly. Amounts are shown in euros (€) on the global site, while the India-facing mirror quotes Indian rupees (INR) with deposits from around ₹300 by UPI. The minimum deposit is low — from about €10 equivalent — but exact withdrawal limits are not itemised consistently in the pages we checked, so confirm them directly before funding an account. As with any offshore-licensed casino, expect full KYC verification before your first payout — and given the logged complaints about withheld winnings and the 3.8/10 'Low' Casino Guru score, budget extra time and keep your own records of every deposit, bonus term and withdrawal request.
