Log in with your mobile number

Four moves, well under a minute on a steady connection. The same details work on the site and in the app, so you only learn them once.

  1. Open the login page

    Type the login address into your phone browser, or tap Log In inside the app. Do not follow login links from SMS or Facebook posts, even when they look right.

  2. Enter your mobile number

    Put in the 11-digit number you registered with, starting 01. Use the number tied to your bKash or Nagad wallet, because withdrawals go back to that same account.

  3. Add the password

    Type it exactly and check that caps lock is off on your keyboard. Tap the eye icon to read what is in the box. Tick Remember me only on a phone that nobody else uses.

  4. Wait for the lobby

    The lobby usually opens in a few seconds. If the button spins for more than a minute, close the tab and start again. Balance, bonus progress and open bets stay on the account.

When login fails: what to check first

Most failed attempts come down to six things. Work down the list before you contact support.

Login problems, likely causes and the fix
What you see Why it happens What to do
Password rejected on every try The phone keyboard capitalises the first letter, or the browser fills in an old saved password. Clear the saved password, type it yourself with caps lock off, then use the eye icon to read it. Still refused? Use the reset link and set a new one.
Message says the number is not registered You signed up with another SIM, or the number changed after a lost phone. Try the other number you own. If the SIM itself was replaced, take your NID to 24/7 Live Chat and ask for the account to be updated before your first withdrawal.
No code arrives by SMS A full inbox, weak signal, or a filter app blocking senders it does not know. Wait a full minute and request one code, not five. Delete old messages, switch off SMS filters, and move the SIM into a phone with better signal.
Page reloads to a blank form Mobile data dropped mid request, or the browser is holding a stale cached copy. Join Wi-Fi, clear the cache in Chrome, and load the login page again. If the app opens fine, the problem sits in the browser, not in your account.
Signed out a minute after signing in Cookies are blocked, so the session cannot be held on that device. Allow cookies for the site, tick Remember me on a phone only you use, and skip private windows, which wipe the session as soon as you close them.
App login screen freezes An APK file older than version 3.6.16, or Android below 7.0. Install the current 52 MB package from the app page, check your Android version in Settings, then sign in with the same number and password.

If two or three fixes fail in a row, stop guessing. A password reset solves most of them without a call.

Keep the account locked to you

Five habits that stop the takeover attempts we see most often. Each one takes a minute or less.

  • Choose a password you have never used

    At least eight characters, with a number and a symbol, and nothing close to your bKash PIN or your email login. Reused passwords are the usual way accounts fall, because one leak exposes every app where the same words were typed.

  • Never pass the SMS code to anyone

    The code that arrives during a login or a password reset belongs to you alone. Our team does not need it to help you, so a caller who asks for it is after the account, not the problem. End the call and log in yourself.

  • Log out on shared phones

    Signing in on a shop handset, a friend's phone or a cyber café is fine now and then. Leave Remember me empty, log out before you hand the phone back, and check your balance later from your own device.

  • Install the APK from this site only

    Install files shared in Facebook groups or Telegram channels can carry extra code that reads your messages. Take the 3.6.16 package from the CK444 in apk app page so the app you open is the one we publish.

  • Read the address before you type

    Save this login page as a bookmark and open it from there. Copies of betting sites sit on lookalike domains and exist to collect passwords. If the address bar shows anything other than ck444inapk.com, close the tab and use your bookmark.

Pick the login route that fits you

Three ways in, one account. The choice comes down to where you are and who else picks up the phone.

Login routes compared
Route What you need Works well when Keep in mind
Mobile number and password The 11-digit number you registered with, plus your password You are on a new handset or a borrowed browser You type the details every time
Remember me on this browser A ticked box on a phone only you use You open the casino lobby several times a day Never tick it on a shared handset
CK444 in apk app The 3.6.16 APK on Android 7.0 or newer You want quick entry and deposit reminders Reinstall after a large Android update

The account name is always the mobile number. There is no separate username to remember, and no second password for the app.

Forgot password: get back in without a call

The reset runs through the same mobile number, so you never need to reach a person.

  1. Request the code

    Tap Forgot password under the login form and enter your registered number. A one-time code goes to that SIM. Use it within the time shown on screen, since older codes stop working once a new one is sent.

  2. Set a new password

    Pick something you have not used on this site before: eight characters or more, with a number and a symbol. Skip your birth year, your SIM's last digits and your bKash PIN.

  3. Sign in everywhere again

    The old password stops working on the website and in the app. Log in with the new one on each device, and end any session you do not recognise from your own phone.

If the SIM is no longer active, the reset cannot reach you. Open 24/7 Live Chat with your NID and the team will verify you before changing anything.

Answers to the login questions we hear most

Short answers to what players ask at the sign-in screen, including the ones about lost SIMs and shared phones.

Can I log in with a username instead of my mobile number?
There is no separate username. The mobile number you registered with is the account name on CK444 in apk, so keep that SIM alive and able to receive messages. If the number changes, ask support to move the account before you request a withdrawal, because payouts return to the wallet tied to it.
What if I forget the password and the SIM is dead?
A reset by SMS needs a working number, so take the case to 24/7 Live Chat instead. Have your National ID card, passport or driving licence ready, because the team checks identity before touching a password. Review takes about 2 hours, and the same check is required before your first withdrawal anyway.
Is it safe to tick Remember me?
Only on a handset nobody else picks up. Ticking it keeps the session open, so the next person to unlock the phone lands inside your account. On a shared phone leave the box empty, log out when you finish, and clear the browser if you have already signed in there.
Why does the app sign me out by itself?
Usually because Android cleared the app cache to free up storage, or you installed an update and the earlier session ended with it. Sign in again with the same number and password. Balance, bonus progress and open bets stay untouched. If it happens every day, reinstall version 3.6.16 from the app page.
Can I stay logged in on two phones at once?
One account is meant for one person. Signing in from a second phone does not create a second account, but it splits your attention and makes a shared password more likely. Keep one phone as your main device, and change the password if you ever see bets you did not place.
Does a bKash deposit log me out?
No. A bKash, Nagad, Rocket or Upay deposit made from inside the app or the site leaves the session open, and the balance updates in the same window. The minimum is ৳150 and most payments land within 4 minutes. If yours has not, keep the transaction ID and open 24/7 Live Chat.

No account yet? Start on the register page

Signing up takes a mobile number, a password and a bKash or Nagad wallet. The first deposit carries a 115% bonus up to ৳13,500, with 20x wagering on the bonus amount.
