👤 Account & Registration

To register, you'll need an active email address, a mobile number, and a strong password. You must be at least 18 years old. Registration is completely free and takes just 2–3 minutes.

No. Each person may only have one account on 399db. Multiple accounts are a violation of our terms and all associated accounts may be closed. Creating multiple accounts to claim bonus offers is strictly prohibited.

On the login page, click the "Forgot Password?" link and enter your registered email. A reset link will be sent — use it within 30 minutes. If you don't receive it, check your spam folder or contact support.

KYC (Know Your Customer) verification is required for security purposes and to prevent underage access. Upload a photo of your national ID or passport and verification is typically completed within 24–48 hours. Your withdrawal limit increases once verification is complete.

You can request self-exclusion or account closure from your account settings. Make sure to withdraw your balance before closing. Visit the responsible gaming page or contact support for more details.

💰 Deposits & Withdrawals

399db supports deposits via Mobile Banking, bank transfer, e-wallets, and other digital payment methods. Visit the cashier page to see all available options.

The minimum deposit amount varies by payment method. For Mobile Banking, the minimum is kept quite low so everyone can get started easily. Check the cashier page for the latest information.

Withdrawals are typically processed within 12–24 hours. Completing KYC verification speeds up the process. Bank transfers may occasionally take 1–3 business days. Your first withdrawal may require additional verification.

Contact live chat with a screenshot of your payment or the transaction ID. Your balance usually arrives within 5–15 minutes. During peak banking hours there may be a slight delay, but if it takes longer than 24 hours, please notify us.

🎁 Bonuses & Promotions

After registering and verifying your email, your welcome bonus is automatically credited to your account on your first deposit. The bonus amount and terms are listed on the promotions page and may change from time to time.

A wagering requirement means you must place a certain amount in bets before you can withdraw a bonus. For example, a BDT 100 bonus with a 30x wagering requirement means you need to wager BDT 3000. Each bonus has its own terms — check the promotions page for details.

Yes. If you want to withdraw without meeting the bonus wagering requirements, you can decline the bonus. You can cancel a bonus through Account Settings or by contacting support — however, the bonus funds will also be forfeited.

Cashback is usually paid out on a weekly or monthly basis. You receive a percentage of your net losses back over a set period. Cashback typically comes with lower wagering requirements — and in some cases can be withdrawn directly.

🎰 Games & Betting

399db offers thousands of slots, Live Casino games (baccarat, roulette, blackjack, poker), bingo, Sports Betting on cricket and football, and virtual sports. New games are added regularly.

Yes, most slots and table games offer a demo mode where you can play for free using virtual money. However, demo mode winnings cannot be withdrawn as real money. Demo mode is generally not available for Live Casino games.

399db uses decimal odds. For example, a BDT 100 bet at odds of 2.50 returns a total of BDT 250 if you win (BDT 150 profit). Higher odds mean a lower chance of winning but a bigger payout. In in-play betting, odds change in real time.

If a bet has already been placed in a slots game, the result is saved on the server. Reconnecting will show you the outcome. In Live Betting, an active bet may be affected if you disconnect — contact support in that case.

📱 App & Technology

You can find the 399db app on the app page. Android users can download the APK and install it directly — just enable Unknown Sources first. iOS users can add it to their home screen straight from Safari.

Enable "Unknown Sources" or "Install Unknown Apps" in your Android settings. If you have an older APK installed, uninstall it before downloading the new one. Make sure you have enough storage space. If the issue persists, use the website in your mobile browser.

399db works best on Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari. Keep your browser updated to the latest version. Clearing your cache resolves most technical issues.

🛡️ Security & Responsible Gaming

Yes. 399db uses 256-bit SSL encryption. Your information is never sold to third parties. Read our Privacy Policy page for full details — we comply with international data protection standards.

Go to the "Responsible Gaming" section in your account settings and set a daily, weekly, or monthly deposit limit. Lowering your limit takes effect immediately — increasing it requires a 7-day waiting period.

If suspicious activity is detected, 399db temporarily locks the account and notifies the owner by email. The account is restored after identity verification. If you're having trouble with your own account, contact [email protected] immediately.
