- Enter your personal details exactly as they appear on your ID.
- Agree to the terms and conditions (read them first).

Bonus Math
Let’s break down a typical welcome bonus step by step. Suppose you deposit €100 and receive a 100% match bonus up to €200, with a 35x wagering requirement on the deposit plus bonus. Here’s the calculation:
Important: Always check the maximum bonus amount and eligible games.
- Bonus amount: €100 (since deposit = €100, match = 100% → €100)
- Total balance: €100 (deposit) + €100 (bonus) = €200
- Wagering requirement: 35 × (deposit + bonus) = 35 × €200 = €7,000
- If slots contribute 100% and table games only 10%, you need to play slots to clear it faster.
- With a 5% house edge on slots, expected loss = €7,000 × 0.05 = €350, which is more than the bonus value. Budget accordingly.
Formula: Required wagering = wagering multiplier × (deposit + bonus). In this case, €7,000. Play low-house-edge games to minimise loss.

Note: Withdrawals to credit cards are often not possible; use an e-wallet or crypto for fastest payouts. The casino may charge a withdrawal fee after a certain number per month.
Licence & Player Protection
The casino operates under a Curacao eGaming license. This means it follows basic standards for fairness and security, but unlike MGA or UKGC licenses, there is no local dispute body in the EU. Important: Winnings from Curacao-licensed casinos may be subject to local income tax in your country — consult a tax advisor. The site uses 128-bit SSL encryption to protect your data, and all games are tested by independent auditors (look for the eCOGRA or iTech Labs seal). For added safety, enable 2FA in your account settings.
Fix It Fast
- Login problem: Clear your browser cache, try incognito mode, or reset your password via email.
- Withdrawal stuck: Check if you have pending wagering requirements or unverified KYC. Contact support with your transaction ID.
- Game not loading: Update your browser, disable ad-blockers, or try a different device. If using the PWA, reinstall it.
- Bonus not credited: Ensure you entered the bonus code correctly and the deposit qualifies. Contact live chat if it doesn’t appear within 10 minutes.
- Account blocked: This usually indicates a KYC issue. Submit the required documents via the verification page and email support.
- Wrong amount shown: Refresh the page or log out and in. If persists, contact support with a screenshot.
Common Questions
How long does it take to verify my account?
Typically 24–48 hours after you upload your documents. Ensure documents are clear and match your registered details.
Can I change my currency after registration?
No, currency is set at sign-up and cannot be changed later. Choose wisely.
Is the mobile site similar to the desktop version?
Yes, the mobile-optimized website (PWA) offers the same games and features. No app download needed — launch from your browser and add to home screen for quicker access.
What is the maximum withdrawal limit?
It varies by payment method and VIP level. Generally, standard is €5,000 per week for regular players, higher for VIPs.
Are there any restricted countries?
Yes, players from the US, UK, Spain, France, and several other jurisdictions cannot play. Check the terms before signing up.
How do I self-exclude from the casino?
Go to Account > Responsible Gambling and set a self-exclusion period. You can also email support to request permanent closure.
Can I play for free without depositing?
Yes, many slots have a demo mode. Free play does not require registration but you cannot win real money.
Worth Knowing
Responsible gambling tools are your friends. Set a deposit limit before you start — you can choose daily, weekly, or monthly caps. Use the session timer to get reminders after an hour of play. If you feel the urge to chase losses, activate self-exclusion for 24 hours or longer. The casino also provides links to gambling help organisations like GamCare and Gamblers Anonymous. Remember: gambling is entertainment, not a way to make money.
