ok77 App — Play Casino & Sports on Your Phone
The ok77 App puts slots, live casino tables, crash games and cricket betting on your Android phone. Install takes under two minutes. Free to download, no browser needed after that.
Android 7.0 or higher · 52 MB · Verified APK
Security First: What the App Asks For
Before you install, here is what the ok77 App accesses on your phone and why. No hidden data collection.
Signed APK — Tamper-Proof Package
Every ok77.apk release is code-signed before publishing. When Android installs it, the OS verifies the signature automatically. If the file was modified in transit, the install will fail with a "Package appears to be corrupt" error. That is your protection against fake copies. Always download from ok77.info/download/ok77.apk — not from third-party APK sites.
Network Access — Why It Is Needed
The app needs internet permission to load live game streams, process bKash/Nagad deposits and show real-time odds. It does not upload your contacts, SMS messages or photos. The network connection goes only to ok77 servers over an encrypted HTTPS channel (TLS 1.3). You can verify this in your phone's data usage screen: all traffic will be listed under "ok77" and nothing else.
Storage — Game Cache Only
The app writes to its own private storage folder for game asset caching and session tokens. It does not read your photos or documents. Total on-device space used after first launch is around 80–100 MB (the 52 MB APK plus cached game assets). You can clear the cache any time from Settings → Apps → ok77 → Storage → Clear Cache without losing your account.
Account Security in the App
Your login session is stored as an encrypted token, not as a plain password. The app supports a PIN lock screen so other people using your phone cannot open it. If you lose your phone, log in from a browser and go to Settings → Active Sessions → End All to revoke access immediately. Two-factor verification is available and strongly recommended. See the ok77 Login guide for setup steps.
Games & Features Inside the ok77 App
Every game category from the full ok77 website is available in the app — often loading faster on mobile data because assets are cached locally.
Slots — over 3,400 Titles
Spin Dragon Hatch, Wild Bounty Showdown, Jungle King and hundreds more from JILI, KA Gaming and Sexy Gaming. The app lobby lets you filter by provider or RTP. Minimum bet from ৳1. Swipe to browse — no lag on 4G or Wi-Fi.
Live Casino — Real Dealers
HD streams from Evolution and Ezugi run smoothly inside the app. Play Andar Bahar, Dragon Tiger or live Baccarat with real dealers 24/7. The tap-to-bet interface is designed for small screens — chip stacks and bet limits are always visible without scrolling.
Crash Games — Aviator & More
Crash Goal from JILI and Crash Bonus from KA Gaming are built for mobile. Watch the multiplier rise, tap "Cash Out" before the crash. The app shows your bet history and auto-cashout settings in a bottom drawer so you never miss your target multiplier. Bets start at ৳1.
Sports Betting — Cricket & Football
Bet on Bangladesh T20 matches, BPL, IPL and international ODIs. The app pulls live scores so you can place in-play bets without switching to another app. Football, kabaddi and tennis markets are also listed. Triple by Evolution handles sports odds inside the platform.
Deposits & Withdrawals — All Methods
Tap the wallet icon to deposit via bKash, Nagad, Rocket, Upay or Bank Transfer. Deposits usually clear in about 1 minute. Withdrawals process in roughly 43 minutes on average. Minimum deposit ৳100, minimum withdrawal ৳1,200. The app sends a push notification when funds arrive.
24/7 Support — Live Chat in the App
Tap the chat bubble in the app's bottom navigation to open live support. Agents are available around the clock in English. For account issues that need a document, use the in-app file upload — you can photograph your NID directly from the camera. Email: [email protected].

If you play mostly on mobile and want fast load times plus deposit alerts, the app is the better choice. If you are on a shared device or prefer not to install anything, use the mobile browser at ok77.info — the experience is the same, just without push notifications.
Android Install Guide — 5 Steps
Android blocks APKs from outside the Play Store by default. Follow these steps in order. The whole process takes about 90 seconds.
-
Allow Unknown Sources
Go to Settings → Security → Install Unknown Apps. Find your browser (Chrome or Firefox) and tap "Allow from this source." This one-time setting tells Android you are intentionally installing an APK that did not come from the Play Store. You can turn it off again after install if you prefer.
-
Download ok77.apk
Tap the "Download APK" button on this page. Your browser will save ok77.apk to your Downloads folder. The file is 52 MB, so give it 15–30 seconds on a standard mobile connection. Do not close the browser tab while downloading — it will pause the transfer.
-
Open the APK File
Once the download completes, Android shows a notification at the top of your screen. Tap it, then tap "Open." Alternatively, open your Files app, navigate to Downloads, and tap ok77.apk there. Android will display a permissions summary screen before install begins.
-
Tap "Install" and Wait
Review the permissions listed (internet and storage) and tap "Install." The installation takes roughly 10–15 seconds. When it finishes, you will see an "App Installed" screen. Do not tap "Open" yet if you have not registered — go to ok77 Register first to create your account, then come back and open the app.
-
Log In and Play
Open the ok77 App, enter your username and password, then tap "Log In." First-time login may take 5–10 seconds to sync your account. After that, every session starts with one tap (or PIN if you set it). Your welcome bonus is credited automatically after your first deposit of ৳100 or more. See the ok77 Casino page for game details.
iPhone Users: Add ok77 to Your Home Screen
Apple does not allow APK installs on iOS. The best alternative is to add ok77.info as a Progressive Web App from Safari. It behaves like an app — full-screen, home screen icon, no browser bars.
-
1
Open ok77.info in Safari
Only Safari supports the "Add to Home Screen" feature on iOS. Chrome and Firefox on iPhone do not. Make sure you are using Safari — the blue compass icon.
-
2
Tap the Share Button
At the bottom of Safari, tap the box with an arrow pointing upward (the Share icon). Scroll down in the share sheet until you see "Add to Home Screen."
-
3
Name It and Confirm
Type "ok77" as the name and tap "Add" in the top-right corner. The ok77 icon will now appear on your iPhone home screen, just like any other app.
-
4
Open and Log In
Tap the icon. The site opens full-screen without the Safari toolbar. Log in to your ok77 account as normal. All games, deposits and withdrawals work the same as on Android.

Install Problems: Causes and Fixes
These five issues cover almost every support request we receive about the ok77 App install. Check this table before contacting live chat.
| Problem | Likely Cause | Fix |
|---|---|---|
| "Install Blocked" message on screen | Android's "Unknown Sources" setting is still off for your browser or file manager. | Go to Settings → Security → Install Unknown Apps, find your browser (Chrome / Firefox), and enable "Allow from this source." Then try the install again. This setting only needs to be changed once. |
| "Package appears to be corrupt" | The APK file did not download completely — the download was interrupted mid-way, leaving a partial file. | Delete the partial ok77.apk from your Downloads folder. Connect to a stable Wi-Fi or 4G network, then download again from ok77.info/download/ok77.apk. Do not close the browser tab while downloading. |
| App installs but crashes on launch | Your phone is running Android 6.x or below, which is below the minimum requirement of Android 7.0. | Check your Android version at Settings → About Phone → Android Version. If it shows 6.x, use the ok77 mobile website (ok77.info) in your browser — the full site works on Android 6. Consider upgrading your phone for best experience. |
| Login fails after install with "Invalid credentials" | The username or password was typed incorrectly, or the account does not exist yet. | Double-check your credentials. If you have not registered, go to ok77 Register and create an account first. If you forgot your password, tap "Forgot Password" on the login screen and follow the SMS reset steps. Need help? Use in-app live chat or email [email protected]. |
| Games load slowly or freeze | Low available RAM or a weak mobile data signal is throttling the game stream. | Close background apps to free RAM. Switch from mobile data to Wi-Fi if possible. Inside the app, go to Settings → Video Quality and select "Medium" — this reduces stream bitrate and stabilises playback on slower connections. Live casino streams need at least a stable 2 Mbps signal. |
Questions About the ok77 App
Straight answers to what most people ask before and after installing.
Is the ok77 APK safe to install on my Android phone?
Yes. The ok77.apk file is code-signed, meaning Android verifies the digital signature before completing the install. If the file were tampered with by a third party, the install would fail automatically. The app requests only internet and cache-storage permissions — it does not access your contacts, SMS, photos or location. Always download from ok77.info/download/ok77.apk and not from third-party APK mirror sites, which may redistribute older or modified versions.
Why is the ok77 App not on the Google Play Store?
Google Play's policies restrict real-money gambling apps in many regions, including Bangladesh. This is a platform policy, not a reflection of the app's safety or legality. Thousands of casino apps worldwide distribute via direct APK download for exactly this reason. The ok77 App is a fully functional, signed Android application — the only difference from a Play Store install is that you need to allow installation from an unknown source once, which takes about 15 seconds in your phone's settings.
How do I update the ok77 App when a new version comes out?
The app checks for updates automatically each time you open it. When version 3.7.6 is superseded by a newer build, you will see an "Update Available" banner inside the app. Tap it and the app downloads and installs the new APK without you having to revisit this page. If you dismiss the banner, you can check manually at Settings → About → Check for Update. You do not need to uninstall the old version first — the update installer preserves your account and game history.
What happens to my account and balance if I uninstall the app?
Your ok77 account, balance and bet history are stored on the server, not on your phone. Uninstalling the app does not affect your account in any way. You can log in from any browser or reinstall the app on a new phone and your full account will be there. The only thing that is lost on uninstall is locally cached game assets, which re-download automatically on first launch. Active bets are settled normally by the server regardless of whether the app is installed.
Can I use the ok77 App on more than one phone at the same time?
Yes, your ok77 account can be logged in on multiple devices simultaneously. This is useful if you switch between a work phone and a personal phone, for example. Each device maintains its own session. If you are concerned about unauthorised access, go to Settings → Active Sessions inside the app to see all logged-in devices. You can terminate any individual session or end all sessions at once from that screen. We recommend setting a PIN lock on each device where the app is installed.
Does the app work on slower 3G connections or when Wi-Fi is weak?
The ok77 App is optimised for Bangladeshi mobile networks. Slots and crash games load fine on a stable 3G connection because game assets are cached after first load. Live casino streams (Evolution, Ezugi) need a minimum of around 2 Mbps for smooth HD video — if your connection drops below that, the app automatically switches to a lower-quality stream rather than freezing. For sports betting and account management, even a 2G connection is sufficient. If you have persistent speed issues, goto Settings → Video Quality and select "Low."
I already have an account on the website. Do I need to register again for the app?
No. The ok77 App and the ok77 website share the same account system. Install the app, open it, and tap "Log In" — enter the same username and password you use on the website. Your balance, bonus, VIP tier and bet history will all be there. If you have not created an account yet, you can register directly inside the app or visit the ok77 Register page first. Either route works. After logging in, your welcome bonus remains active if you have not yet made your first deposit.
What to Do After You Install
