Android: five steps from download to first bet
On an iPhone?-
Allow installs from your browser
Open Settings, then Apps, then Special app access, then Install unknown apps. Pick the browser you download with, Chrome or Samsung Internet, and switch on Allow from this source. Android blocks every APK until you do this once.
-
Download ck444inapk.apk
Tap the Download APK button on this page. The 41 MB file saves to Downloads. Keep the screen awake until the progress bar finishes, because a dropped connection leaves a broken file that the installer will refuse.
-
Open the file you just saved
Pull down the notification shade and tap the finished download, or open Files, then Downloads and tap ck444inapk.apk. If Android asks which app should handle it, choose Package Installer rather than a file viewer or archive tool.
-
Confirm and wait for the install
Tap Install. Play Protect may show a warning about an unknown developer, which is normal for files outside the Play Store. Choose Install anyway only when the file came from this page and shows 41 MB.
-
Log in and make a deposit
Open the app, tap Login and use the same number and password as the website. No account yet? Register first, then deposit from ৳200 with bKash, Nagad, Rocket, Upay or bank transfer. Most deposits land in about 3 minutes.
iPhone and iPad: a shortcut on the home screen
There is no iOS install file. Safari can save the site as a home screen icon that opens full screen without the address bar, which feels close to an app after the first login.
- Open the site in Safari. Chrome on iOS cannot save the shortcut.
- Tap the Share icon at the bottom, scroll the list, then tap Add to Home Screen.
- Name it CK444, tap Add, then open it and sign in through the login page.
The shortcut keeps your session until you clear Safari data. Your account, wallet and bonus progress are on the server, not on the phone.
What the CK444 in apk app actually does
App or browser?One account, both versions
Login details, balance and bonus progress carry across the app and the website. Same wallet, same withdrawal history. Log in on a browser at a friend's place and your session is exactly where you left it.
Cashier in two taps
bKash, Nagad, Rocket, Upay and bank transfer are built in. Deposits from ৳200 clear in about 3 minutes, withdrawals from ৳700 take about 41 minutes, and first-time ID checks are handled before money leaves.
Cricket and football markets
Prices on domestic Bangladesh matches and international tours, plus football leagues through the season. The bet slip stays pinned to the bottom of the screen so you can add a market without leaving the scoreboard.
Small stakes, real rounds
Nine from Pragmatic Play takes spins from ৳1 and Dragon Tiger from ৳10, so a session does not need a big bankroll. RTP and bet limits appear on the game tile before you open it.
Support inside the app
The 24/7 live chat opens over the table you are playing, so a stuck deposit does not cost you the round. Ask there for the document list if a withdrawal request needs an ID check.
Updates that keep your data
When a new build appears, download the fresh APK and install it over the old one. Login, balance and saved wallet numbers stay. The build listed here, 3.5.7, is dated 11 November 2026.
Games you can open from the home screen
Full casino lobby
The lobby behind the app holds 3,100 titles from Pragmatic Play, CQ9, FA Chai, Playtech and Ezugi. Two examples of what a small bankroll can reach:
App or browser: pick by how you play
Odds, RTP and bonus rules are the same in both places. What changes is the working experience: how often you re-download, whether alerts reach you, and how much of your data pack the first screen eats. Use the table as a quick check of the trade-offs.
| What changes | CK444 in apk app | Mobile browser |
|---|---|---|
| Install | One 41 MB file, once | Nothing to install |
| Phone storage | About 41 MB plus app data | Only browser cache |
| Opening speed | Menus and art are kept on the phone | Reloads the lobby each visit |
| Alerts | Deposit, withdrawal and market notifications | None unless you ask for them |
| Updates | Download the new APK yourself | Always the current build |
| Cashier | Built-in screens for all five payment methods | Same screens, one more tap |
| Login | Stays signed in until you log out | Signs out when you clear browsing data |
Choose the app when you play mostly on mobile data and want deposit alerts. Stay on the browser when the phone is shared, when you switch devices often, or when you want the newest build without re-downloading anything.
Permissions: what the file asks for and why
An APK from outside the Play Store always looks suspicious to Android, so it helps to know exactly which permissions the install touches and which it leaves alone.
Install unknown apps
Android asks once, per browser. It is the switch that lets the APK run at all, not a permanent setting.
Turn it back off after installing; the app keeps working.
Storage
Used for the downloaded file and for updates you install later. The app writes to its own folder.
It does not read your photos, messages or other app data.
Notifications
Deposit confirmations, withdrawal status and market alerts. Useful on match nights, easy to switch off.
Manage or mute them in Android settings at any time.
Network and payments
Needs Wi-Fi or mobile data to load games and the cashier. There are no card numbers stored in the app.
Deposits run through bKash, Nagad, Rocket, Upay or bank transfer, so your PIN stays in the wallet app.
Before installing, check two things: the file size (41 MB) and the version (3.5.7). If a download page asks for card details, it is not this site. Keep the phone to yourself, log out on shared handsets, and play only with money you can afford to lose.
When the install goes wrong
Most failed installs are a half-finished download or a switch Android turned off by default. Work down this table before you ask for help.
| What you see | Why it happens | What to do |
|---|---|---|
| "App not installed" | The APK is incomplete, usually after a dropped connection | Delete ck444inapk.apk, download again on Wi-Fi, check it shows 41 MB, then open it once more |
| Blocked by Play Protect | Play Protect flags any file that does not come from the Play Store | Tap More details, then Install anyway. If you prefer, run the file through Play Protect's own scan first |
| Nothing happens on tap | Browser is blocking downloads, data saver is on, or storage is full | Allow downloads for the site, switch data saver off, clear a little space, then retry the button |
| App opens, then closes | Phone runs Android below 8.0, or an old build is still cached | Check Settings, About phone, Android version. On 8.0 or newer, uninstall the old APK and install 3.5.7 clean |
| Login fails only in the app | Typo in the number, or an old password saved by the keyboard | Reset the password on the login page, type it by hand once, then let the keyboard save the new one |
Still stuck? The 24/7 live chat answers in English and Bangla and can see whether your deposit reached the wallet. Have the file size and your Android version ready.
Answers before you tap install
Is the CK444 in apk app APK safe to install?
The file linked on this page is the build we publish: 41 MB, version 3.5.7. Android will warn about any APK that comes from outside Play, so read the warning instead of skipping past it. If you got the file from a mirror, a forum or a Telegram forward, delete it and download here again.
How do I update to a newer version?
Download the new APK from this page and open it while the old app is still installed. Android replaces the build and keeps your login, balance and saved wallet numbers. Do not uninstall first, or you will have to sign in again and re-add your payment details.
Why does Android say "app not installed"?
Almost always an unfinished download. A 41 MB file that stops halfway still looks like a file to Android, so the installer refuses it. Delete ck444inapk.apk, download again on a stable connection, confirm the size in your Files app, then open it. If it repeats, try Samsung Internet instead of Chrome.
Can I install it on an iPhone or iPad?
No APK runs on iOS. iPhone and iPad users get a Safari home screen shortcut instead, which opens the full site without the address bar and behaves much like an app after the first login. Account, wallet and bonus rules are identical to Android.
Do I need a separate account for the app?
No. Create the account once, on the website or inside the app, and the same number and password work on both. Bonus progress, deposit history and your VIP tier follow the account rather than the handset, so changing phones or switching to a browser changes nothing. Register on the site first if you have not yet.
Does the app cost anything?
The download is free and there is no subscription or monthly fee. Your costs are the deposit itself and whatever your operator charges for data. Minimum deposit is ৳200, minimum withdrawal is ৳700, and the cashier shows any wallet charge before you press confirm. Nothing is taken from winnings for using the app.
What happens to my bets if I switch between app and browser?
Nothing. Both versions read the same wallet and the same bet history, so a round open in the app continues in the browser. Log out of one before opening the other if you share the phone. If a game looks frozen, close it and reopen: the round usually settles itself.
Install once, then play from the home screen
The file is 41 MB and works on Android 8.0 and newer. After the first sign-in, opening CK444 in apk takes one tap and your session stays.
