4kbd's policy is one account per person — no individual may hold two or more accounts. However, two separate adults in the same household — such as a husband and wife or two brothers — may each have their own account, provided each person has a unique mobile number, email address, and National ID. Multiple accounts can be logged in from the same device, just not simultaneously — each user must log in and out separately. If someone attempts to create duplicate accounts to claim bonuses more than once, the system will detect it and both accounts will be permanently closed with all balances forfeited. If you have any doubts, email support@4kbd.click before registering.
4kbd has a dedicated mobile app available for both Android and iOS devices. However, it may not be listed directly on the Play Store or App Store — so the most reliable option is to access 4kbd.click through your mobile browser. The site is fully optimized for mobile, works just as fast as an app, includes all features, and requires no separate download. Android users who want to install the APK app can log in to 4kbd.click and navigate to the "Mobile App" or "Download App" option — then download the APK file from there. Before installing, go to your phone's settings and enable "Unknown Sources" or "Install from unknown apps." Once the file is downloaded, tap it and hit the "Install" button. For iOS users, the mobile site is the best option — open 4kbd.click in Safari and tap "Add to Home Screen" to get a shortcut that works just like an app. If you run into any installation issues, reach out via the support chat.
For security reasons, some account details can be updated directly while others require support assistance. Details you can change yourself: profile photo, address, password, and email notification preferences — log in and update these directly from your profile settings. To change your mobile number, you'll need to contact support, as it's tied to payment verification and account security. Reach out to support with both your old and new mobile numbers — an OTP will be sent to each for verification before the change is processed. This typically takes up to 24 hours. For name changes, your details are cross-checked against your KYC records — if there's a significant discrepancy, you may need to submit a copy of your National ID. To access your profile settings, log in and follow this path: profile icon (top right) → "Account Settings" → "Personal Information".
4kbd automatically sets Bengali as the default language for users in Bangladesh. If English or another language appears instead, switching is straightforward. When logged in, look for a flag icon or language selector in the upper-right corner of the page — click it and select "Bengali." The change takes effect immediately and persists across future login sessions. Even without logging in, a language-change option is available in the footer area at the bottom of the page. On mobile, open the hamburger menu (the three-line icon) — the language option is available there as well. If your browser's language setting is already set to Bengali, the site is more likely to load in Bengali automatically. If the issue persists after trying these steps, reach out via the support chat.
Simply registering does not activate your welcome bonus — it's triggered by your first deposit. This is referred to as the "Welcome Bonus" or "First Deposit Bonus." Here's how the process works: complete registration → verify your mobile number with OTP → make your first deposit via bKash, Nagad, or any other supported method. Once the deposit is confirmed, the bonus is automatically credited to your bonus wallet — usually within 5 to 15 minutes. For the current welcome bonus amount and terms, check the Promotions page, as these details may change from time to time. Before you can withdraw bonus funds, you must meet the wagering requirement — meaning you need to place bets totaling a specified multiple of the bonus. For example, with a 5x wagering requirement, a ৳100 bonus requires ৳500 in total bets before withdrawal. Your bonus wallet and main wallet are kept separate — after logging in, you can see both clearly in the Wallet section.
Yes, 4kbd offers real-time live scores. After logging in, go to the Sports Betting section and look for matches marked with a green "Live" tag — clicking it takes you to that match's detail page. There you'll find live updates including runs, overs, wickets, goals, and match time. Scores are typically updated every 30 seconds to 1 minute. Live video streaming is available for selected matches. To watch a stream, you must be logged in and have a positive account balance. Streaming may not be available for every match, as it depends on broadcasting rights. Matches with streaming available are marked with a camera icon in the interface. On mobile, turning off Data Saver mode will improve streaming performance. For the best experience, use a Wi-Fi or 4G connection.
All current and upcoming 4kbd promotions are listed on the "Latest Promotions" page, which is directly linked from the navigation menu. This page is updated at least two to three times a week. During major cricket series or football tournaments, new offers can appear almost daily. There are a few ways to make sure you never miss a deal. First, log in regularly and check your dashboard — personalised offers are shown after you sign in. Second, go to your account settings and enable email or SMS notifications so you're alerted as soon as a new offer goes live. Third, if you add 4kbd.click to your home screen via your mobile browser's "Add to Home Screen" option, you'll get the option to turn on push notifications. Every offer has an expiry date — you must claim it before it runs out. Always read the terms carefully, as each offer has its own minimum deposit and wagering requirements.
