Winna review: licence, withdrawals, complaints and verdict

Image: Winna on X

Winna is a crypto casino and sportsbook at winna.com, operated from Costa Rica by GG Gaming and licensed by the Tobique Gaming Commission. It went live in mid-2024, raised $15 million within six months, and has grown into what Casino.guru now classes as a big casino. It stands out in our crypto casino guide for holding a Tobique licence rather than the more common Curaçao or Anjouan ones.

• Launched: mid-2024 (CryptoSlate and Casino.guru; AskGamblers lists 2025)
• Operator: GG Gaming LLC, registered at Sabana Business Center, San José, Costa Rica (the licence is held as GG Gaming S.R.L.)

• Coins: BTC, ETH, USDT, USDC, DAI, SOL, LTC, BNB, TRX, DOGE, XRP and TON, as listed by Casino.guru in 2026
• KYC: ID can be requested at any time; enhanced checks from around €2,000 in 24 hours
• Games: slots, live dealer, provably fair Originals and a sportsbook
• UK and US: both are on Winna's prohibited list
• Our rating: Mixed

A sizeable Tobique-licensed casino with a named team and strong Casino.guru scores, weighed down by a $10,000 daily withdrawal cap, a withheld Trustpilot rating and a steady stream of complaints about held withdrawals and closed accounts.

We rate crypto casinos from public sources only: the licence and what it covers, who owns it, what players report about withdrawals and complaints, how clear its terms are and how long it has been trading. Last reviewed 20 October 2026. How we rate crypto casinos.

Winna launched in the summer of 2024 and announced a $15 million seed round in December that year. World Casino Directory reported on 25 December 2024 that it had more than 10,000 active players, offices in Costa Rica and Switzerland, and plans to spend the money on player-versus-player games and its VIP programme. That report named Paul Martens as chief executive and co-founder and Elias Platzer as head of player development. No investors were named.

The company behind it is GG Gaming. Winna's terms of service name GG Gaming LLC with an address at Sabana Business Center in Mata Redonda, San José, and Casino.guru lists the owner as GG Gaming Sociedad de Responsabilidad Limitada. The Tobique licence list shows GG Gaming S.R.L., the same company in its Spanish legal form.

CryptoSlate adds two points worth knowing: Winna began trading with only a Costa Rican business registration, which is not a gambling licence, and gained the Tobique licence within its first year; and neither a Costa Rican registration number nor a Tobique licence number is published on the site. Its X account, @Winna, opened in April 2025 and had about 16,100 followers on 20 October 2026.

Winna is a full-service site. Its home page claims more than 6,000 games from 39 providers; Fair Gambling counted 5,323 games from 54 providers, and AskGamblers lists about 48 studios, including Pragmatic Play, Hacksaw Gaming, Evolution, Nolimit City, Play'n GO, NetEnt, Relax Gaming, Red Tiger and BGaming. The totals vary because libraries change and each site counts differently.

Those studios include plenty we cover, such as Hacksaw (Le Bandit Hold & Win), Nolimit City (Duck Hunters 2) and Pragmatic Play (Gates of Olympus 2500). Availability differs by region, so check the lobby before assuming a game is there.

The in-house Winna Originals are Blackjack, Coin Climber, Coinflip, Dice, Hilo, Keno, Limbo, Mines, Plinko, Roulette, Tower, Twenty One and Wheel. Fair Gambling puts the top Originals at 99% RTP, matching the 1% house edge the company advertised in 2024. The sportsbook runs on Betby, according to Fair Gambling and CryptoSlate, and covers around 40 sports with live betting and a bet builder.

The most important number is the cap. Winna's terms set a standard withdrawal limit of $10,000 per 24 hours, which VIP hosts can raise at their discretion; Casino.guru and AskGamblers record the same limit. The minimum withdrawal is $20 per transaction, every deposit must be wagered once, and several withdrawals in 24 hours may carry a processing fee. A big winner is paid in instalments unless the casino agrees otherwise, and Fair Gambling user reviews include one player describing a large win paid under a daily limit.

AskGamblers lists crypto withdrawals at 0 to 24 hours, and Winna pays out at weekends. The terms say withdrawals go back to the method used to deposit, and wrong wallet addresses are the player's loss.

KYC is not optional in practice, despite a "no KYC" games category on the site's own home page. The terms let Winna ask for identity, address and payment documents at any time and suspend withdrawals until checks are done. Its AML and KYC policy sets automatic alerts at around €2,000 in 24 hours and describes enhanced checks, including payslips, tax returns or bank statements, for flagged accounts. The terms also allow only one account per individual, household, IP address or device, a rule that can catch out people sharing a flat.

The licence checks out. The Tobique Gaming Commission licence list shows GG Gaming S.R.L. as a B2C licensee with an expiry date of 8 May 2027, and Casino.guru marks the licence as verified. The register does not list domains, and Winna does not print a licence number, so the link between the two rests on the operator's name.

Tobique is a First Nation regulator based in New Brunswick, Canada. It is less common among crypto casinos than Curaçao or Anjouan, but it is still an offshore-style licence with limited player dispute routes, and it does not let Winna serve New Brunswick itself: the province is on Winna's prohibited list, alongside Ontario. The terms send unresolved disputes to the EGIS resolution body and are governed by Costa Rican law.

Winna's Originals are provably fair, with a public verification page, and Casino.guru found no unfair clauses in its terms. We found no published proof of reserves; Fair Gambling's on-chain estimate put Winna's hot wallets at about $2.1 million in September 2026, which is an outside estimate rather than an audit.

Winna's pitch is rewards rather than a big welcome offer. Fair Gambling lists instant rakeback, weekly and monthly bonuses, level-up rewards and weekly and monthly lossback, with VIP tiers from Bronze (from $1,000 wagered) up to Nebula (over $100 million), and a $500,000 leaderboard and raffle pool. Its own test estimated rakeback at about 33% of the house edge.

The bonus policy gives Winna wide discretion: it can change or cancel any offer without notice, review play history after the event and void winnings from strategies it considers guaranteed-return or from bonus rounds started on bonus money. As always, wagering rules make bonuses worth less than their face value.

Reward cuts are a recurring theme in reviews. Fair Gambling user reviews describe a "version 2" update and a later "birthday" update that reduced lossback and VIP treatment, and Trustpilot reviewers in August and October 2026 complain about low bonuses and VIP transfer terms not honoured. These are player reports, not confirmed policy changes.

We could not confirm a current streamer partnership for Winna from a source we could open. A trade site has reported that one streamer left Winna for Stake, but we could not verify it, so we name no one here. Affiliate leaderboards are clearly part of Winna's marketing, and some Trustpilot reviews in September and October 2026 are disputes over unpaid affiliate leaderboard prizes and commission.

Streamers on crypto casinos often play with balances supplied by the casino, so their results say little about what a paying player can expect.

We found no regulator action, court ruling or hack against Winna. What there is, in quantity, is player complaints about held withdrawals, closed accounts and changed rewards. As of 20 October 2026:

• Trustpilot: the rating is withheld. Trustpilot's notice says the rating is unavailable "due to a breach of our guidelines" and that it removed a number of fake reviews for the company. The 687 reviews split almost evenly, 46% five-star and 45% one-star. Recent reports include an account disabled after an $11,000 withdrawal request (18 October 2026), withdrawals stuck on pending (27 August 2026), unpaid affiliate winnings (7 October 2026) and several allegations of rigged games, which are unverified.
• Casino.guru: Safety Index 9.3 (very high), user feedback rated Bad from 16 reviews. 39 complaints: 11 resolved, 27 rejected, 1 open, none unresolved. Recent ones include an account closed after a self-exclusion request ($20,604 disputed), deposits asked for after self-exclusion (7,506 USDC) and funds confiscated on a closed account (700 USDT).
• AskGamblers: CasinoRank 6.1 out of 10, four complaints all marked resolved, including a $199 deposit held for months after KYC and around $3,800 of withheld winnings.
• Fair Gambling: 18 complaint cases filed with it and 33 unresolved scam accusations on BitcoinTalk, alongside user reviews averaging 4.2 out of 5. BitcoinTalk accusations are unproven forum posts.

Winna has replied publicly to some Trustpilot reviews. Taken together, the volume is partly a function of size, which Casino.guru weighs in its score, but the self-exclusion cases and the withheld Trustpilot rating are the points we would want answered before trusting it with a large balance.

The good:

• Tobique licence on the regulator's list, valid to May 2027
• A named chief executive and over two years of trading
• Casino.guru Safety Index of 9.3 and no unfair terms found
• Broad library, Betby sportsbook and provably fair Originals at 99% RTP
• Clear written AML and KYC policy

The bad:

• $10,000 daily withdrawal cap unless a VIP host lifts it
• Trustpilot rating withheld for a guideline breach, with fake reviews removed
• Steady complaints about pending withdrawals, closed accounts and self-exclusion handling
• No licence or company registration number on the site, and it traded unlicensed at first
• Players report reward cuts after platform updates

Our verdict: Winna is a sizeable, licensed operator with a named team, and the main review sites that weigh complaints against size rate it well. It also caps withdrawals at $10,000 a day, launched before it held a gambling licence, and carries a Trustpilot warning and a long list of player disputes, some about self-exclusion. Real strengths next to real concerns make it Mixed. Big winners in particular should read the withdrawal terms first.

Winna's terms list the UK as a prohibited country, and Casino.guru records that it does not accept UK players. It has no UK Gambling Commission licence, which any site needs to offer gambling to people in Great Britain, so UK players would have no GAMSTOP or UKGC protection there. The USA, Germany, the Netherlands, Spain, Ontario and New Brunswick are also on its prohibited list.

Crypto adds its own risks: balances rise and fall with the coin, blockchain transfers cannot be undone, and you are usually paid in the coin you deposited. Bonuses come with wagering rules.

Is Winna legit?

Winna is a licensed business: the Tobique Gaming Commission lists its operator, GG Gaming S.R.L., as a licensee until May 2027, and it has traded since mid-2024 under a named chief executive. Casino.guru gives it a Safety Index of 9.3. Against that, Trustpilot has withheld its rating for a guideline breach and players report held withdrawals and closed accounts. We rate it Mixed.

What is the Winna withdrawal limit?

Winna's terms set a standard limit of $10,000 per 24 hours, which a VIP host can raise at the company's discretion. The minimum withdrawal is $20, every deposit must be wagered once first, and several withdrawals within a day may carry a processing fee. Large winners should expect to be paid in daily instalments unless they agree a higher limit.

Does Winna require KYC?

Yes, when it chooses to. Winna's terms let it request ID, address and payment documents at any time and hold withdrawals until checks are complete, and its AML policy flags activity of around €2,000 in 24 hours for review. A "no KYC" games category on its home page does not change those rules, so expect verification before a large cash-out.

Who owns Winna?

Winna is run by GG Gaming LLC, registered in San José, Costa Rica, and the Tobique licence is held by GG Gaming S.R.L. A December 2024 report on its $15 million seed round named Paul Martens as chief executive and co-founder. Winna does not publish its company registration number or licence number on the site.

Can UK players use Winna?

No. The UK is on Winna's list of prohibited countries and the casino holds no UK Gambling Commission licence, which is required to offer gambling in Great Britain. Players on unlicensed sites have no GAMSTOP or UKGC protection. The USA, Ontario and New Brunswick are among the other places it excludes.

Why is Winna's Trustpilot rating unavailable?

Trustpilot says the rating is unavailable because of a breach of its guidelines, and that it has removed a number of fake reviews for the company. It does not say who posted them. The remaining 687 reviews split almost evenly between five stars and one star, with withdrawals, VIP terms and fairness the main complaints.
