Most iGaming guides are vague. This one is not — every step here is specific, actionable, and based on how the platform actually works.
Quick Checklist
- Ensure you are at least 18 years old and in a jurisdiction where online gambling is legal.

- Set your deposit and session limits immediately after registration to play responsibly.
- Read the terms and conditions of the welcome bonus before claiming it.
Step-by-Step Sign-Up

Calculating Your Bonus
Let’s walk through a concrete example using the typical welcome offer: a 100% match bonus up to €200, plus 50 free spins. The math below applies to any similar promotion.
Formula for the bonus amount:
Bonus = min(Deposit × Match Percentage, Maximum Bonus)
If you deposit €150:
150 × 100% = €150, which is below the €200 cap, so your bonus = €150.
If you deposit €300:
300 × 100% = €300, but the cap is €200, so your bonus = €200.
Wagering requirement: Assume it is 35× the bonus amount (common for match bonuses).
Required wagering = Bonus × 35
For a €150 bonus: 150 × 35 = €5,250 must be wagered before you can withdraw any winnings from the bonus.
Free spins value: 50 free spins at €0.10 per spin = €5 total bet. Any winnings from free spins are typically also subject to a wagering requirement, often the same 35×. If you win €20 from free spins, you must wager 20 × 35 = €700.
Total playthrough: To clear both the deposit bonus and the free spin winnings, you need to wager the sum of the requirements. In the €150 deposit example with €20 free spin winnings:
Total = €5,250 + €700 = €5,950.
Important: slot contributions vary. Most slots count 100% toward wagering, but table games and live dealer games typically contribute only 5–20%. Always check the full terms.
Is It Safe?
The platform operates under a Curaçao eGaming license, which imposes standard requirements for fair play and player fund segregation. All data transmitted is encrypted using 128-bit SSL technology. The casino requires full KYC verification before processing withdrawals, a measure that prevents fraud and money laundering. While Curaçao-licensed casinos do not fall under strict EU or UK regulations, they generally provide safe gameplay. A user tip: winnings from a Curaçao-licensed casino may be subject to local income tax in your country of residence; consult a tax advisor to stay compliant.

Support Guide
Five common scenarios and how to resolve them:
- Account locked after several failed login attempts – Use the Forgot Password link to reset credentials. If that doesn’t work, contact live chat (available 24/7) and provide your registered email for a manual unlock.
- Forgot your password – Click Forgot Password on the login page, enter your email, and follow the reset link sent to your inbox. Check spam if it doesn’t arrive within 5 minutes.
- Welcome bonus not credited after deposit – First, confirm you entered any required bonus code. If it still doesn’t appear, wait 10 minutes (credit can be delayed). If nothing, contact support via live chat with your username and deposit transaction ID; they will manually credit the bonus.
- Withdrawal pending for more than 48 hours – Check that your account is fully verified. If verification is complete and the pending period has passed, ask live chat to escalate the withdrawal to the finance department. Keep a record of your withdrawal request.
- Requesting self-exclusion – Go to Responsible Gambling in your account settings, select self-exclusion, and choose the duration (e.g., 6 months, 1 year, indefinite). Alternatively, email support with your request; they will process it within 24 hours and confirm in writing.
Support channels: 24/7 live chat, email (support@domain – not provided), and a phone line (available in select countries).
Worth Knowing
The platform offers several responsible gambling tools to help you stay in control:
- Deposit limits – Set daily, weekly, or monthly caps on how much you can deposit. Limits can be lowered immediately but take 7 days to increase.
- Session time reminders – Enable a pop-up that appears after a chosen period (e.g., every 30 minutes) showing how long you’ve been playing.
- Reality check – A periodic summary of your wins, losses, and time spent since logging in.
- Self-exclusion – Block yourself from the casino for a fixed period or permanently. During exclusion, you cannot log in or access any services.
These settings are found under the Account menu in the Responsible Gambling section. We recommend setting deposit and session limits before making your first deposit.
Common Questions
How long do withdrawals take?
Withdrawals are processed after a pending period of up to 48 hours. E-wallet withdrawals then take another 24–48 hours, card withdrawals 3–5 business days, and bank transfers 5–7 business days. Cryptocurrency withdrawals are usually settled within 24 hours after the pending period.
Is the casino licensed?
Yes, it holds a Curaçao eGaming license (license number available in the footer of the site). This license ensures regular audits of game fairness and player fund security.
What is the minimum deposit?
The minimum deposit is €10 for most payment methods (except bank transfer, which requires €20). Cryptocurrency deposits require a minimum equivalent of €20.
Are there any fees on deposits or withdrawals?
The casino does not charge fees. However, your bank or e-wallet provider may apply a small transaction fee (e.g., 1–2% for currency conversion). Always check with your provider.
How do I claim the welcome bonus?
After registering and making your first deposit, the bonus is credited automatically if you used the correct bonus code (if required). If not, contact support. The bonus typically has a 35× wagering requirement and must be used within 30 days.
Can I set a deposit limit?
Yes, you can set daily, weekly, or monthly deposit limits in the Responsible Gambling section of your account. Limits can be reduced instantly, but any increase takes effect after 7 days.
What currencies does the casino accept?
The main currency is EUR. Some payment methods allow transactions in USD or GBP, but the balance is displayed in EUR. Cryptocurrency balances are shown in BTC, ETH, etc.
Is there a mobile app?
The casino does not offer a downloadable native app. Instead, it provides a mobile-optimized website that works in any browser. You can add it to your home screen as a progressive web app (PWA) for faster access.
What happens if my account becomes dormant?
An account is considered dormant after 12 months of no login. The casino may charge a monthly administration fee (e.g., €5) after that period. To avoid fees, simply log in at least once a year.
Getting started with this platform is straightforward if you follow the steps above. Use the bonus math to understand the true playthrough requirement, always set responsible gambling limits first, and contact support immediately if any issue arises. Good luck and play smart.
