The OKTK app brings the full betting experience to your Android phone. Cricket, football, Color Game, Charge Buffalo, Monster Crash — everything is right there in your pocket. Download the OKTK app now and never miss a moment of the action.
Getting the OKTK app on your Android phone takes less than two minutes. Follow these three steps and you are ready to bet.
On your Android phone, go to Settings → Security → and enable "Install from Unknown Sources" or "Allow this source." This lets you install the OKTK APK file directly without going through the Play Store.
Tap the Download button on this page. The OKTK APK file is only 18 MB so it downloads in seconds even on a 3G connection. Once the download is complete, open the file from your notifications bar.
Tap Install when prompted. The OKTK app installs in under 30 seconds. Open it, login with your existing account or register for free, and you are straight into the games and betting markets.
The OKTK app is not just a mobile version of the website. It is a purpose-built betting app designed around how players in Bangladesh actually use their phones.
The OKTK app loads in under two seconds on a standard 4G connection. No waiting for pages to refresh, no browser tabs slowing things down. Odds update in real time and bets are placed instantly — speed matters when you are betting live.
Never miss a bonus, a live match, or a big odds movement again. The OKTK app sends push notifications directly to your phone — bonus alerts, match start reminders, withdrawal confirmations, and more. You stay in the loop without having to check the app constantly.
Set up fingerprint or face unlock on the OKTK app and you never have to type your password again. One touch and you are in. It is faster, more convenient, and more secure than typing credentials every time you open the app.
Deposit and withdraw directly through bKash and Nagad from inside the OKTK app. The payment flow is optimised for mobile — no redirects, no copy-pasting account numbers. Deposits reflect in your OKTK wallet within minutes.
The OKTK app gives you full access to live in-play betting markets. Watch odds shift in real time during cricket and football matches and place your bets at exactly the right moment — all from your phone, wherever you are.
The OKTK app is optimised to use as little battery and mobile data as possible. It runs smoothly on older Android phones and does not drain your data plan. You can bet comfortably on a 3G connection without lag or dropped sessions.
Both work, but the OKTK app gives you a noticeably better experience across the board.

The OKTK app is the fastest and most convenient way to access everything the platform has to offer. Whether you are placing a bet on a Bangladesh cricket match, spinning through a round of Color Game, or checking your rewards balance on the way to work, the OKTK app makes it seamless. This guide covers everything — from downloading the app to getting the most out of it every day.
Most players in Bangladesh use their phones for everything, and betting is no different. The OKTK app is built specifically for Android devices and is optimised for the way people actually use their phones here — on mobile data, often on older devices, and in situations where speed and reliability matter.
The app is smaller than most social media apps at just 18 MB, installs in under 30 seconds, and runs smoothly on any Android phone running version 5.0 or above. That covers the vast majority of phones in use across Bangladesh right now.
Everything available on the OKTK website is available in the app — and then some. Here is what you get:
Yes. The OKTK app APK is scanned and verified before every release. It does not contain any malware, spyware, or unwanted software. The only reason you need to enable "Install from Unknown Sources" is because Google does not allow betting apps on the Play Store — not because there is anything unsafe about the file itself.
Once installed, the OKTK app uses the same SSL encryption as the website. Your login credentials, payment details, and personal information are all protected. The app does not store your password on your device — it uses a secure token system that expires automatically.
Currently the OKTK app is available for Android only. If you are using an iPhone, you can still access OKTK through your mobile browser — the website is fully responsive and works well on Safari and Chrome on iOS. The mobile browser experience on iPhone is smooth and covers all the same features, though you will miss out on push notifications and biometric login.
An iOS version of the OKTK app is in development. Check back on this page for updates.
When a new version of the OKTK app is released, you will receive a push notification prompting you to update. You can also check the version number in the app's settings menu and compare it to the latest version listed on this page. Updates are usually small — under 10 MB — and install in seconds.
Keeping the app updated ensures you always have the latest games, the most current odds feeds, and any security patches that have been released. It is worth doing as soon as an update is available.
If the OKTK app is not installing, the most common reason is that "Install from Unknown Sources" has not been enabled on your device. Go to Settings → Security (or Privacy on some devices) and toggle the option on. Then try opening the APK file again.
If the app installs but will not open, try restarting your phone and opening it again. If you are seeing a login error, make sure you are entering your mobile number without the +880 prefix — just start with 01. For any other issues, OKTK support is available 24/7 and can be reached via the FAQ page.
18 MB. Free to download. Works on any Android phone. The full OKTK experience — games, sports, wallet, rewards — right in your pocket.
