No more opening a browser and logging in every time. Download 688tk once and access slots, fish games, and cricket betting directly from your home screen. Just 38 MB, installs in 30 seconds.
Most people in Bangladesh use Android phones, so the 688tk APK is built specifically with Android users in mind. Every step is explained below in plain, simple language.
Tap the APK download link on the official 688tk site. The file will start downloading and the progress will appear in your phone's notification bar. Do not close the page until the download is complete.
Go to Settings → Security → Unknown Sources (or Install Unknown Apps) and enable it. On Android 8 and above, you only need to grant permission for Chrome or your download manager — not for the entire phone.
Once the download is complete, tap the notification or open your Files or My Files app, go to the Downloads folder, and open the 688tk.apk file.
The installation screen will show an "Install" button. Tap it and wait 20–30 seconds. Once complete, you will see an "App installed" message.
Open the 688tk app. If you already have an account, log in. If not, register with your mobile number in just 2 minutes and claim your welcome bonus.

Due to Apple's policies, 688tk is not available on the App Store. However, iPhone and iPad users can get the same experience through a PWA (Progressive Web App). Once set up in Safari, it looks and works just like a native app.
The PWA supports push notifications, a home screen icon, and fullscreen mode — all the key features, without taking up any storage since all data is stored in the cloud.
Open Safari on your iPhone or iPad and go to 688-tk.com. Note that PWA installation is not supported from Chrome or Firefox.
Tap the Share icon (box with an arrow pointing outward) at the bottom center of the screen.
Scroll through the Share menu, find "Add to Home Screen", and tap it. Confirm the name and tap Add.
The 688tk icon will appear on your home screen. Tap it to open the app in fullscreen mode.
Many people wonder — why download a separate app when the website is already there? It's a fair question. But the difference becomes clear from day one. Typing the URL every time, logging in repeatedly, waiting for pages to load — these small frustrations add up and make the whole experience feel like a chore.
Once you log in to the 688tk app, you can use biometrics (fingerprint or Face ID) for faster access next time. Switching to bKash during payment and returning is seamless. You can pause a game mid-session and pick up right where you left off. The app runs in the background, so your session stays active even when your phone is locked.
Internet speeds aren't always reliable in rural areas and small towns across Bangladesh. The 688tk app is designed with this reality in mind. Core features work even on a 2G connection, and slots or Fish Game run smoothly on 3G. Enable Low Data Mode to reduce image loading and cut down on data usage.
688tk leads the way when it comes to security. Websites carry the risk of phishing attacks — someone can set up a fake site that looks identical to the real one. But once installed, the 688tk app always connects to the official server with no way to be spoofed. Every session runs on token-based authentication.
Features you will notice on your first day after downloading
Loads 3x faster than the website. The app's caching system avoids reloading the same content repeatedly, which also saves data.
No need to type your password. A fingerprint or face scan logs you in within seconds.
Match kicks off, goals, wickets, bonus offers — all updates delivered straight to your phone. Notifications are visible even when your phone is locked.
Save your bKash, Nagad, or Rocket details once and every future deposit or withdrawal takes just a single tap.
Play Fish Game or slots in full landscape mode across the entire screen. Browser bars and notification banners won't get in the way.
Every transaction and session data is encrypted with 256-bit AES. No third party can access your information in any way.
