Warnings! Unable to verify Winbig21 Casino license information

Winbig21 Casino has been around since 2012 and is open to players worldwide. It features a decent selection of games from multiple providers. But before you dive in, there are a few red flags worth knowing. 

The casino claims to be licensed in Curacao, but there’s no way to verify it, which is a bit shady. On top of that, the bonus terms aren’t very player-friendly. In this review, we’ll break it all down so you know exactly what to expect.

Trustworthiness & Licensing Review

Winbig21 Casino gives us some serious concerns about whether it's safe and honest. The casino says it has a Curacao gambling license (#8048/JAZ), but when we checked their website, we couldn’t find any real link or proof of that license. There’s no clear way to check if their license is real. This makes it look like they could be lying or using a fake license.

Although the casino has been operating since 2012, that doesn’t guarantee credibility. Several reasons explain its low rating:

  • Weak regulation: Winbig21 appears to operate under a Curacao license, which lacks the strict oversight found in more reputable licensing jurisdictions. This allows the site to remain active despite player complaints.
  • Aggressive promotions: Attractive bonuses and large offers likely help the casino draw in new users, keeping it afloat despite issues.
  • Lack of awareness: Many players may not be aware of the casino’s negative reputation or fail to check reviews before signing up.

Moreover, Winbig21 has been blacklisted by several reputable review sites, mostly due to unpaid winnings and poor customer support.

Until they show clear proof of their license, we don’t recommend playing here. A casino with no real license is risky. You might not get your money back, and there’s no one to help if something goes wrong. Check out our list of trusted online casinos for safer alternatives.

Game Collection

Winbig21 Casino offers 790+ games, covering popular categories:

  • 675 slot games with various styles and themes.
  • 36 table games, including standard options like blackjack, roulette, and baccarat.
  • 15 video poker titles with some variety for poker-style play.
  • 15 live dealer games with real-time gameplay.
  • 50+ specialty games, including keno, bingo, scratch cards, and other casual titles.

The game collection seems designed mostly for slot-focused users, with just enough variety to cover other types of games. Still, the number of live dealer and table games is somewhat limited, so players mainly looking for those categories might find fewer options. 

The game collection is for slot-focused users

These games are from several established providers, including:

  • Betsoft
  • Rival
  • Saucify
  • Tom Horn Gaming
  • Spinomenal
  • Vivo Gaming
  • Felix Gaming, Dragon Gaming, Fugaso, and others

The website includes basic filtering tools like a search bar and tabs for new releases, top picks, and live games. The interface is straightforward and the game visuals, based on the thumbnails shown, appear in line with what’s typically expected from the mentioned providers.

However, RTP percentages are not shown for any of the games. This lack of transparency makes it harder for players to assess how fair or rewarding the games might be compared to others.

Bonuses and Promotions

At Winbig21 Casino, you’ll find a variety of bonuses and ongoing promotions. These include:

  • 400% welcome bonus
  • 100% cashback insurance
  • Weekly raffles
  • Comp points
  • Tournaments 
  • Themed events

Wagering requirements: For free bonuses like chips or comp points, the requirement can be 20x to 60x, depending on the offer. Even cashback, while lower at 1x WR, has rules attached.

There are various bonuses and ongoing promotions at Winbig21 Casino

On the surface, these offers may look appealing, especially if you're new or enjoy regular promotions. However, it's important to look beyond the headlines. The bonus terms here are quite strict, and understanding them fully is key before you decide to claim anything.

Note: The site doesn’t show wagering requirements or withdrawal limits clearly on the promotions page. You’ll need to dig into the terms and conditions to find this information.

Bonus Terms: Read Before You Regret

  • Bonuses are non-withdrawable. You can play with them, but you can’t cash them out. When you withdraw, the bonus will be removed.
  • Payout limits apply. Free chip wins are usually capped (e.g. 50 units). Big bonuses (like 200%) often limit cashouts to 10x your deposit.
  • Free bonus players face extra rules. You must deposit before withdrawing. Plus, only winnings from your first three free bonuses (within 30 days) can be cashed out. The rest? Forfeited.

Payment Methods

Payout Time

Not Stated, Pending Time: 7 - 10 days

Supported Currencies

The available methods are fairly standard, but limited transparency about which wallets or vouchers are accepted may be inconvenient. You’ll need to reach out to support to find local options. The 3% fee on deposits is a downside, especially when many online casinos offer fee-free deposits.

There’s no specific time frame given for how long withdrawals take after verification. You’ll be added to the "next available payment cycle" once documents are approved, which leaves room for delays.

Note: To cash out your winnings, you must submit identity verification documents, including:

  • A photo ID (passport or national ID card)
  • A utility bill
  • A copy of your bank card (if used)
  • A signed Card Authorization Form

If you use an e-wallet like Neteller or Skrill, only the ID and utility bill are required.

Mobile Compatibility

Winbig21 Casino is accessible directly from your mobile browser, there's no app download required. Menus are straightforward and easy to tap, but the design feels a bit dated compared to newer mobile-optimized casinos. 

You can access Winbig21 Casino directly from your mobile browser

On mobile, you’ll find nearly the full range of games and promotions available on the desktop version. This includes slot games, table games, live dealer options, and even the same daily or weekly bonuses, cashback offers, and tournaments. 

Customer Support

Winbig21 Casino provides several ways to get in touch with their support team:

    • France: (+33) (0)1 789 00368
    • Spain: (+34) 91 290 1420
    • International: (+1) 718 732 0154

We tested Winbig21’s support through live chat, email, and phone. Live chat connected us in about 3 minutes, but the responses felt rushed and copy-pasted. When we asked about payment options, we were told to contact finance and the chat ended quickly. Email support took over 24 hours to respond with vague, unhelpful answers. We also called the international number, but it went straight to voicemail with no follow-up.

So, support is available, but not very responsive or detailed. Live chat works, but don’t expect fast or personalized help. Phone and email support are weak.

Player Protection Tools (Responsible Gaming)

Winbig21 Casino provides basic responsible gaming tools, but relies too heavily on manual support requests to activate them. They are:

  • Deposit limits
  • Self-exclusion
  • Self-limit options

These tools are not available through your player account directly. Instead, all changes must be made by manually contacting customer support, which can slow down the process for someone who needs immediate help. 

There’s also no mention of time limits, session reminders, or loss limits, which are common at casinos with more advanced player protection features. So, if you're looking for quick, self-managed options within your account, this setup is not for you. 

Conclusion & Recommendations

Winbig21 Casino offers a decent game selection, but concerns like an unverifiable license, strict bonus terms, and slow withdrawals raise red flags. The lack of transparency and outdated support processes make it hard to recommend. If you value fast payouts, fair bonuses, and solid licensing, you may want to explore more reputable and well-regulated alternatives.
