• Verify you are logged into your existing Mystake casino account — do not create a new one.
• Check the Promotions page for the latest reload bonus, free spins, or cashback offer.
• Review the bonus terms: wagering requirements, eligible games, max bet limits, and expiry dates.
• Enter any required coupon code in the cashier before making the qualifying deposit — some offers auto-credit.
• Set a deposit limit if you want to stay in control of your spending.
• Contact support via live chat if you are unsure about any rule — screenshot the terms for reference.

Bonus Mathematics

Let us break down a typical reload bonus for existing Mystake casino customers. Assume a 50% bonus up to €200 with a 35x wagering requirement on the bonus amount only.

Example calculation:

If you play only slots: you need to wager €1,750. With an average RTP of 96%, expected loss is €1,750 x (1 – 0.96) = €70. Your total deposit + bonus is €150, so your expected final balance after wagering is €150 – €70 = €80 — meaning you likely end with €80 or less if you meet the requirement. To improve your odds, choose games with high RTP (above 97%) and lower house edge.

Financial Operations

Mystake supports multiple deposit and withdrawal methods. Deposits are usually instant, while withdrawals take 1–5 business days depending on the method. Here is a quick comparison:

For existing players using a promo code, note that the bonus amount is usually credited after the qualifying deposit. Some offers require the code to be entered before the deposit — always double-check.

Security

Mystake uses 256-bit SSL encryption to protect your personal and financial data. The platform is licensed under Curacao eGaming. All transactions are processed through secure payment gateways. For added protection, enable two-factor authentication (2FA) in your account settings. Always use unique passwords and avoid sharing your credentials. In case of any suspicious activity, contact support immediately. Note that winnings from a Curacao-licensed casino may be subject to local income tax depending on your country of residence — check with a local tax advisor.

Worth Knowing

If your withdrawal is delayed beyond the stated timeframe, follow these steps:

• Check your email for any verification requests — you may need to submit KYC documents (ID, proof of address, payment method screenshot).
• Log in to your account and go to the Withdrawal History section to see the status (Pending, Processing, Completed).
• Contact support via live chat — provide your withdrawal ID and the amount. Ask for the exact reason for the delay.
• If it has been more than 48 hours past the maximum processing time, request escalation to a manager.
• If unresolved, file a complaint with the Curacao licensing authority (usually requires 30 days after initial report).

When Things Go Wrong

1. Bonus not credited after deposit: Ensure you entered the promo code in the cashier before depositing. Check the bonus expiry — some offers auto-credit only during specific hours.
2. Game not contributing to wagering: Verify the game weight in the bonus terms. Slots usually count 100%, while table games count 5–20%.
3. Withdrawal rejected due to bonus playthrough: You must complete the wagering requirement before requesting a withdrawal. Check your bonus progress in the account.
4. Self-exclusion request: Contact support via email with your request. The casino must process it within 24 hours. Keep a copy of the correspondence.
5. Account suspended after winning: This may happen due to a security review. Provide KYC documents promptly. If the suspension lasts more than 7 days, escalate to the licensing authority.
