Most iGaming guides are vague. This one is not — every step here is specific, actionable, and based on how the platform actually works. Whether you are logging in to use a reload bonus or exploring the loyalty rewards, this guide covers the exact steps, math, and troubleshooting for existing Mystake customers.
What You Need First
- A verified Mystake account (email and KYC documents approved)
- Access to the Mystake app or the mobile-optimized website — both work identically
- A stable internet connection (Wi-Fi or 4G/5G)
- At least the minimum deposit amount required for the specific promo (usually €20–€50)
- The promo code if required (some offers auto-credit; others need manual entry)
How to Sign Up (as an existing customer claiming a promo)
- Open the Mystake app or visit the Mystake casino website via your browser
- Log in with your username and password. If you have two-factor authentication enabled, enter the code from your authenticator app
- Go to the ‘Promotions’ or ‘Bonuses’ section. Any active offers for existing customers will be listed there
- Select the promo you want. If a code is needed, it will be shown — copy it or note it down. For explicit entry, go to the cashier before depositing
- Head to the cashier and choose your deposit method. Enter the promo code in the designated field (if required). Some deals auto-activate without a code
- Enter the deposit amount that meets the minimum (e.g., €25) and confirm the transaction. The bonus should credit instantly or within a few minutes
- Check your bonus balance under ‘My Account’ > ‘Bonus History’ to ensure the funds are active
If you are ever unsure about which promo codes apply to your account, visit Mystake promo code existing customers directly and check the ‘My Offers’ tab — it shows all personal deals without needing to search.
Bonus Math
Understanding the real value of a reload bonus requires a simple calculation. Here is an example using a typical existing customer offer: 100% match up to €100 with a 30x wagering requirement on the bonus amount.
Important: Wagering requirements apply only to the bonus, not to the deposit, unless stated otherwise. The formula to find the total amount you need to wager before withdrawal is:
Total Wagering = (Bonus Amount) × (Wagering Multiplier)
If you deposit €50 and receive a €50 bonus (100% match):
- Bonus = €50
- Wagering = 30 × €50 = €1,500
- So you must place bets totaling €1,500 before the bonus cash becomes withdrawable
Now consider the impact of game contribution percentages. Slots often contribute 100%, while table games might contribute only 10–20%.
- If you play slots (100% contribution): every €1 bet counts fully. So, €1,500 in bets on slots will clear the wagering
- If you play blackjack (10% contribution): only 10% of each bet counts. A €10 bet only adds €1 to the wagering progress. You would need to bet €15,000 on blackjack to clear the €1,500 wagering requirement
To estimate effective value, use this formula:
Expected Value (EV) = Bonus – (Wagering × House Edge)
Example for a slot with 96% RTP (house edge = 4%):
- EV = €50 – (€1,500 × 0.04) = €50 – €60 = –€10
- This means you can expect to lose €10 on average, so the bonus is negative value in the long run
Always check the specific RTP of the games you plan to play. High RTP slots (97%+) reduce the expected loss and can make a promo worthwhile.
Security Overview
Mystake casino operates under a Curacao eGaming license, which means it complies with international standards for fair play and data protection. The platform uses 128-bit SSL encryption to protect all transactions and personal information. Two-factor authentication (2FA) is available and strongly recommended for your account. For withdrawals, the KYC process requires a copy of your ID, proof of address, and occasionally proof of payment method — this is a one-time check that ensures your funds are safe.
Note: Because Mystake holds a Curacao license, winnings are not automatically tax-free in your home country. You may be responsible for reporting and paying local income tax on gambling winnings. Check your local laws or consult a tax advisor.
Banking & Payments
| Payment Method | Deposit Time | Withdrawal Time | Minimum Deposit |
|---|---|---|---|
| Visa/Mastercard | Instant | 1–3 business days | €20 |
| Skrill | Instant | Under 24 hours | €10 |
| Neteller | Instant | Under 24 hours | €10 |
| Cryptocurrency (BTC, ETH, USDT) | Instant (after network confirmations) | Under 1 hour | €20 equivalent |
| Bank Transfer | 1–3 business days | 3–7 business days | €50 |
For existing customers, the fastest withdrawal methods are e-wallets (Skrill, Neteller) and cryptocurrencies — often processed in under an hour. Credit cards and bank transfers take longer due to clearing times. Always check if the deposit method you use is eligible for bonus activation; some e-wallets may be excluded from certain promotions.
Common Problems & Fixes
- Problem: Promo code not accepted
Fix: Ensure you are using the correct code without spaces. The code is often case-insensitive, but caps lock can still cause issues. Try copying and pasting from the promotions page - Problem: Bonus not credited after deposit
Fix: You may have selected a payment method that is excluded from the bonus (e.g., Skrill for some offers). Check the terms and conditions of the promo. If everything is correct, contact support via live chat - Problem: Wagering progress not updating
Fix: Some games (like live dealer or table games) have lower contribution percentages. Play only slots with 100% contribution to see progress. Also, check that you are using real money after the bonus is active, not bonus funds first - Problem: Withdrawal pending status for days
Fix: Verify that your KYC documents are fully approved. If not, submit them again. Cryptocurrency and e-wallet withdrawals are typically faster — consider switching if speed is critical - Problem: Mobile app crashing or lagging
Fix: Clear your browser cache or reinstall the Mystake app if using the PWA. Update your browser to the latest version. The mobile-optimized website works on all modern smartphones without installation
Extra Tips
When wagering a bonus, choose games with the highest return-to-player (RTP) percentages. Slots like Blood Suckers (98%) or Jackpot 6000 (98.9%) offer some of the best theoretical returns. Avoid scratch cards and keno, which often have RTP below 90% and will eat into your bonus value faster. For table games, European roulette (97.3% RTP) is better than American roulette (94.74%). Blackjack with basic strategy can approach 99.5% RTP, but check contribution first — many bonuses exclude table games completely or cap their contribution.
Need to Know
Can existing customers claim the welcome bonus again?
No, the welcome bonus is for new players only. Existing customers receive reload bonuses, cashback offers, and loyalty rewards instead.
Do I need a promo code for every bonus?
Not always. Some bonuses auto-credit when you make a deposit during a promotional period. Codes are usually only needed for specific one-time offers or exclusive deals.
How long do anti-money laundering rules keep my funds pending?
AML checks rarely delay withdrawals for existing players after their first one. If triggered, you will need to provide proof of funds source, which can take a few days.
What happens to my bonus if I request a withdrawal before wagering is done?
You lose the bonus and any winnings generated from it. Always complete the wagering requirements first, then withdraw.
Can I cancel a bonus after it is active?
Yes, most bonuses can be forfeited by contacting support or by going to the bonus section and selecting ‘Cancel Bonus’. Any winnings from the bonus are removed.
Is the mobile app available on iOS and Android?
Mystake uses a progressive web app (PWA) which you can add to your home screen from the browser. It is not available on Google Play or Apple App Store but works and looks like a native app.
How do I receive promotions for existing customers?
Check your email and the ‘Promotions’ tab on the site. You can also enable push notifications in the Mystake app to be alerted about new deals.
What is the maximum withdrawal amount per transaction?
Standard limits are typically €4,000 per week for fiat and €7,500 for crypto, but these vary by VIP level. Check the cashier for your specific limits.
This guide breaks down every step for existing Mystake customers looking to maximize their bonuses. Use the math to evaluate offers, stick to high-RTP games, and always verify the terms before depositing. With the right approach, you can turn a reload bonus into real value.
