How to Install the tk4 App on Android
Betting apps aren't available on the Google Play Store, so you'll need to download the tk4 APK directly. It only takes a small settings change — nothing complicated.
Enable Unknown Sources
Go to your phone's Settings → Security or Privacy and enable "Install from Unknown Sources" or "Unknown Apps". On Samsung devices, this option may appear as "Install Unknown Apps".
Download APK
Tap the "Download APK" button above. The file will be saved to your phone's Downloads folder. At just 48 MB, it downloads in about 30 seconds even on a regular connection.
Open from File Manager
Go to your Downloads folder and tap the tk4.apk file. Hit "Install" and it'll be ready in just a few seconds.
Log In or Register
Open the app. If you already have an account, log in. New here? Register — it takes just 30 seconds. All you need is your mobile number.
Deposit & Play
Deposit via bKash, Nagad, or Rocket. Payments through the app are simple — just enter your bKash number, send directly, and your account gets credited within seconds.

Why is the tk4 app so popular?
People in Bangladesh do everything on mobile — from banking to shopping. So when it comes to gaming, the mobile app is the natural choice. tk4 gets that, which is why they built their app with Bangladeshi users in mind.
Picture this: Pohela Boishakh night in Cox's Bazar, waves crashing in the background, and you're spinning a slot on the tk4 app — vivid animations lighting up your screen. That kind of seamless experience is only possible with a great app. A browser just can't match it.
Network speeds aren't always reliable in Barishal or other district towns across the country. tk4's low-data mode addresses that directly. Slots and crash games run without interruption even on a 3G connection — slightly reduced graphics, but the full game experience is there. For Live Casino, a 4G connection is recommended.
A lot of users have questions about app security. The tk4 APK is security-tested before every update. SSL encryption keeps all your data protected. Your bKash or Nagad number is never shared with any third party.
About app updates — tk4 releases one major update every month, covering new games, bug fixes, and performance improvements. If push notifications are enabled, you'll be alerted whenever a new update is available. To install an update, simply download the latest APK again — the process is exactly the same as before.
