3999 bit App — Full Cricket Betting and Casino Experience on Mobile
Place bets on T20 matches, spin slots and join the live casino right from your phone screen — the 3999 bit app keeps your account, balance and all features in one place.
3999 bit App — Mobile Gaming Made Easier
The 3999 bit mobile app is built for players in Bangladesh who want to enjoy betting and casino games from their phone. The app is available for both Android and iOS and can only be downloaded through official channels.
Many people think the app and the browser require separate accounts — that is not the case. Your 3999 bit account, balance, bonuses and betting history remain the same whether you use the app or your phone's browser. Register once and log in from any device; everything will be exactly as you left it.
For detailed instructions on installing the app, see the 3999 bit APK Installation Guide.
Open the App — Everything in One Place
When you open the 3999 bit app, you get sports markets, the casino lobby, payment options and support all on one screen.
Cricket and Sports Betting
Bet on local and international matches including BPL, IPL and the T20 World Cup. The 3999 bit cricket betting section is fully usable from the app — watch live scores and place your bet before the odds change.
Slots and Live Casino
Play hundreds of slot games from PG Soft, Pragmatic Play, JILI and more, plus live tables from Evolution and Ezugi, directly on your phone. The 3999 bit slots section has a list of popular games and RTP information.
Deposit and Withdrawal
Deposit and withdraw directly from within the app using bKash, Nagad, Rocket, Upay or bank transfer. Minimum deposit is ৳300 and minimum withdrawal is ৳500 — the same rules apply on both the browser and the app.

View Bonuses and Offers
Weekly reload bonuses, slot festival bonuses, cricket season offers — all promotions can be viewed in the bonus section of the app. You will be notified when new offers arrive.
App or Browser — Which Should You Choose?
Same account, same balance — but there are a few differences between the two that are worth knowing.
| Feature | 3999 bit App | Phone Browser |
|---|---|---|
| Account and Balance | Same | Same |
| Push Notifications | Available | Limited |
| Login Speed | Fast | Depends on the browser |
| Live Betting | Smooth | Works |
| Deposit / Withdrawal | All methods | All methods |
| Installation | Required once | Not required |
All features of 3999 bit are fully available through both — there is no difference in account or balance. The choice is yours.
Secure Login and Account Protection on Your Phone
Using your account on mobile is convenient, but following a few precautions will keep your account fully secure.
- Keep your screen locked — lock your phone with a fingerprint or PIN so no one else can open the app without permission.
- Verify your OTP yourself — when logging in or making a payment, use the OTP only yourself; do not share it with anyone.
- Never share your password — no 3999 bit staff member will ever ask for your password by phone or chat.
- Avoid public Wi-Fi — using your own mobile data or a trusted network gives you better security.
- Log out when done — if you use someone else's phone or a shared device, always log out when you are finished.
You can log in to your account directly from the 3999 bit Login page and find the option to reset your password there.
Tips for Running the App Smoothly
A few simple habits will help you avoid any trouble during live betting or gaming.
- Keep a stable connection — a good internet speed is important when placing bets on live matches. For mobile data, a 4G or 5G connection is preferable.
- Keep the app updated — when a new version is available, update through the official channel. Some features may be limited on older versions.
- Clear the cache — if the app is running slowly, go to your phone's settings and clear the app cache; this often resolves the issue.
- Turn off battery saver mode — having battery saver on during live betting or slots can slow down the app.
- Keep notifications on — turning on app notifications means you will not miss new bonuses, match starts or withdrawal updates.
- Contact support if you have a problem — for any technical issue with the app, Bengali-language help is available 24/7 via live chat.
