Mobile internet use in Bangladesh has now overtaken desktop — and 399 tk built its mobile app with exactly that in mind. It's not just a scaled-down website; it's a standalone experience. Whether you're stuck in Dhaka traffic, on the Chittagong coast, or near a tea garden in the Sundarbans, the app lets you play from anywhere.
The app is built with equal attention to both Android and iOS. Many platforms focus primarily on Android, but 399 tk ensures a full experience for iOS users as well. Installing it as a PWA from Safari works just like a native app.
Many users feel a little hesitant about installing from "Unknown Sources" — that's completely understandable. But the 399 tk APK comes directly from our official servers and every release is virus-scanned. Downloading via an SSL-encrypted link means no one can tamper with the file in transit.
The reason it's not on the Play Store is straightforward — online betting apps aren't eligible for direct listing under Google Play's policies. That's why most betting platforms worldwide distribute via APK. It's not unsafe, just a slightly different process.
When logging in for the first time after installation, enter your phone number or email and password. Once logged in, you'll have the option to enable biometric login — after that, just use your fingerprint.
Slots and crash games run most smoothly on mobile. Spinning on a touchscreen feels completely natural. Live Casino games like baccarat and roulette also play well on mobile, though a stronger connection makes the experience even better.
In the Sports Betting section, viewing live odds and placing bets on cricket, football, and tennis matches is very easy on mobile. A larger screen may show more information at once, but the mobile interface is laid out so the key details are always front and centre.
Mobile internet speeds in Bangladesh can vary quite a bit. The 399 tk app is built with this in mind — in low-bandwidth mode, game graphics are slightly reduced automatically to keep loading times fast. Gameplay stays smooth; only background animations are toned down a little.
For live dealer games, a minimum 5 Mbps connection is recommended. On 4G or a solid Wi-Fi connection, you'll get perfectly smooth video streaming.
The 399 tk app uses SSL/TLS encryption, which means your login credentials and payment data are never exposed over a public network. The app never requests access to your phone's camera, microphone, or contacts — only notification permission is asked for.
If you forget your password, you can reset it directly from the app by sending an OTP to your phone number. It's also recommended to keep two-factor authentication (2FA) enabled — you can turn it on anytime from Settings.
Download the 399 tk app and enjoy the best gaming experience from anywhere. Registration is completely free.
