💰 Bonuses & Promotions – All Your Questions Answered

How do I get the Welcome Bonus?

Open a new account at 40a and your first deposit will automatically trigger a 100% welcome bonus — no code needed. The bonus appears in your balance as soon as the deposit is confirmed.

Why can't I use my bonus?

Bonuses cannot be withdrawn directly – they become usable only after the wagering requirement is met. For example, a ৳1,000 bonus requires ৳10,000 in bets (10x). Full terms are available on the bonus page.

When will I receive my cashback?

40a's weekly cashback is credited every Monday morning. VIP members receive between 5% and 15% cashback, with no wagering requirements attached.

Bonuses are generally valid for 30 days. Any unused bonus may be forfeited after expiry. Keep your notifications on so you don't miss out.

Keep Your Account Secure

  • Never share your password with anyone

🔒 Security & App Guide

Download Android App

Download the APK from the official 40a website. Enable "Install from unknown sources" on your device. Installation takes around 30 seconds.

iOS / iPhone App

Open 40a.bet in Safari, tap the Share button, then select "Add to Home Screen" – it works just like an app.

If the App Isn't Working

Check your internet connection. Close the app and reopen it. Clear the cache. If the issue persists, try reinstalling the app.

App Update

Download the latest APK directly from the 40a site regularly. Each new version includes new features and bug fixes.

KYC Verification – Why It's Required & How It Works

Before your first major withdrawal at 40a, you'll need to complete KYC (Know Your Customer) verification. This is mandatory to keep your account secure. Typically, all you need to do is upload photos of the front and back of your NID card along with a selfie.

Verification is usually completed within 1–3 hours. Once verified, you won't need to do it again.

40a Help Center – About Our Services

The 40a Help Center is more than just an FAQ page – it's a genuine support hub built for users in Bangladesh. Our support team communicates entirely in Bangla and is well-versed in the local issues Bangladeshi users face.

New users often worry about whether their issues will get resolved. At 40a, we make sure every problem is handled quickly. Our live chat average response time is just 2 minutes – the best of any betting platform in Bangladesh.

Beyond support, our Help Articles section contains over 150 guides covering everything from registration to the VIP programme, all written so that even first-time users can follow along with ease.

40a always aims to help users find solutions on their own – which is why the search bar is so important. But when self-service isn't enough, a Bengali-speaking agent on live chat is ready to assist you right away.

Responsible Gambling – How to Set Your Limits

40a believes betting should be fun, not stressful. If you feel your betting habits are getting out of control, 40a offers self-exclusion and deposit limit options to help you stay in charge.

You can set daily, weekly, or monthly deposit limits from your profile settings. Once enabled, deposits exceeding the set amount will not be allowed. If you need further assistance, Responsible Gaming View page.

If you'd like to temporarily deactivate your account

❓ Help Center – FAQs

Direct answers to the questions 40a users ask most.

All you need to open an account is an active Bangladeshi mobile number. Registration is completed with your name, date of birth, and a password. KYC verification can be done later – it's only required before large withdrawals. The whole process takes under 2 minutes.

bKash deposits are usually credited to your 40a balance within 30 seconds to 2 minutes. If it takes longer than 5 minutes: 1) Refresh the page, 2) Check your SMS to confirm the bKash transaction was successful, 3) Contact 40a Live Chat with your transaction reference number. Most issues are resolved within 5 minutes.

bKash and Nagad withdrawals are typically processed within 5–15 minutes. Bank transfers may take 1–3 hours. If KYC verification hasn't been completed, your first withdrawal may take longer. VIP members receive priority withdrawal processing.

If the wagering requirement isn't met before the bonus expires (usually within 30 days), the bonus balance will be forfeited. Your original deposit and any winnings, however, remain unaffected. The bonus only applies to that specific extra amount.

If you suspect unauthorized access to your account, act immediately: 1) Contact us via Live Chat and request a temporary account suspension, 2) Notify support if your mobile number has been changed. The 40a security team will investigate promptly and take the necessary action.

No. Under 40a's rules, each person may only hold one account. Creating multiple accounts from the same device, IP address, or phone number may result in all accounts being closed and funds being confiscated. This rule is in place to prevent platform abuse.

Common reasons games won't load: slow internet, an outdated app version, or a temporary server issue. Fix: check your internet speed, update the app, and clear the app cache. If the problem continues, try accessing 40a through your mobile browser.

Your weekly cashback is credited directly to your 40a wallet every Monday morning. You can find it under Profile > Transaction History in the app or website, labeled "Cashback." You'll also be notified via SMS and push notification.
