Download the 123bdt App APK and open crash games in one tap
The 123bdt App puts the lobby on your home screen: slots, crash rounds and live tables one tap from the phone in your hand. No typing the address again on a slow connection, no losing your place when a call cuts a round short. Download the file, sign in once, and the icon stays.
The file is 28 MB, version 2.1.20, and it runs on Android 8.0 or newer. Reading this on a phone? Tap the button above, or use the download section further down the page.
A small app for the phone you carry all day
The app is a trimmed copy of the site: same account, same balance, same games, fewer page loads between them. It is built for the handset in your pocket, the one with a dozen tabs open and a signal that comes and goes.
- 28 MB installed, which leaves room for the photos and chat apps already on the phone.
- Crash rounds keep the stake field and the cash-out button on the same screen.
- bKash, Nagad, Rocket and Upay open from the cashier without a second sign-in.
- Android 8.0 and newer. Nothing about your account changes when you switch devices.
Scan with your phone camera to open this page on the handset you will install on.
App or browser: which fits the way you play
Both routes reach the same account and the same balance, so the choice is about taps and data, not about access. The real difference shows up when the signal drops in a bus, or when you want the cash-out button under your thumb.
| Situation | 123bdt App | Mobile browser |
|---|---|---|
| Opening the lobby | One tap on the icon and the last screen you used comes back. | Type the address and sign in again if the browser cleared the tab. |
| Data used per visit | Interface files sit on the phone, so only game content loads fresh. | Every visit pulls the full page from the network. |
| Crash rounds | The multiplier and the cash-out button stay in one window. | Same games, more scrolling before you reach the stake field. |
| Live tables | Streams open in the app player, away from background tabs. | Video quality depends on how many tabs are still open behind it. |
| Cashier | Opens on your last used method, so the wallet step is two taps. | Same cashier, reached through the menu each time. |
| Storage on the phone | 28 MB for the installed file. | Nothing but a few cached images. |
| Updates | Install the newer APK from this page when a build appears. | Nothing to install. The site updates on its own. |
Use the browser on a borrowed handset or a shared phone, where you would rather not leave an icon behind. Keep the app on the phone you use daily, so the round, the cashier and the stream sit within reach.
Six things the 123bdt App does in one screen
The build is deliberately narrow. It covers the screens players open most and drops the rest, which is why it loads quickly on a mid-range Android phone.
Crash rounds on one screen
Aviator and Crash Goal open in a full window with the stake field, the multiplier and the cash-out button in reach. Your thumb does not travel to find the button while the round is still climbing.
Cashier with your last method
bKash, Nagad, Rocket and Upay appear in the order you used them. Type the amount once, finish inside the wallet app, and return to the screen you left open. Deposits usually show in about 5 minutes.
A lobby that loads on weak data
The first screen shows eight featured titles before the rest of the 5,700 game library. That matters in a moving bus or a market, where the signal drops between towers and a heavy page never finishes painting.
Sign-in that survives a closed app
The app keeps the account signed in between sessions, so a call or a flat battery does not send you back to the password field. On a shared handset, sign out from the app menu each time you finish.
Alerts you can switch off
Notifications cover deposit confirmations and the closing day of a bonus. They are optional. Turn them off in the phone settings and the app still opens, plays and pays out without sending a single pop-up.
Points that follow the account
Cashback, tier progress and the daily withdrawal limit belong to the account, not to the handset. Play a session on the app and a round on a laptop, and the totals still land in the same place.
Crash, slots and live tables from the same icon
The icon opens the same lobby you see on the website. Crash titles sit at the top, slots sit behind them, and the live rooms with cricket markets are a tap further in. Two titles players open first:
The full room list, including the live dealer tables, is on the casino page.

What the phone needs before you start
- Android 8.0 or newer. Older builds cannot open the file at all, whatever the download says.
- 28 MB of free space for the download, plus a little room for the app cache after the first session.
- A steady connection for the first sign-in and the wallet step, because both talk to our server in real time.
- The bKash, Nagad, Rocket or Upay number you registered with, ready for the first deposit.
Install the APK on Android in five steps
The order matters. Android blocks files from outside the Play Store until you allow one browser to install them, and that switch is the step most people miss on the first try.
-
Let your browser install files
Open Settings, then Apps, then Special access, then Install unknown apps. Pick the browser you download with and switch the permission on. Android 8.0 and newer keeps this per app, so it stays off until you set it yourself.
-
Save the APK from this page
Tap Download APK above. The 28 MB file lands in your Downloads folder and a notification appears when it is complete. If the transfer stalls, check that data saver is off and the phone has room for it.
-
Open the file and confirm
Tap the finished download. Android lists the permissions the app uses, then shows an Install button. If the phone still warns about unknown sources, the switch from step one was applied to a different browser than the one you used.
-
Sign in or open an account
Existing players sign in with the same number and password as the website. New players can register here and return to the app, or use the login page to reset details before opening the icon.
-
Test the cashier with a small deposit
Send ৳400 or more through bKash, Nagad, Rocket or Upay and watch the balance update, usually inside 5 minutes. Withdrawals reach the same wallet in about 3 minutes once the first one clears.
Adding the page to an iPhone home screen
There is no iOS build, and we would rather say that than point you at an Android file that cannot run on your phone. Safari can still put an icon on the home screen, and it opens full screen without the address bar.
- Open 123bdt in Safari itself, not inside a chat app's built-in browser.
- Tap the share icon at the bottom of the screen, then pick Add to Home Screen.
- Name the shortcut 123bdt and tap Add. It behaves like an app from then on.
What the app asks for, and what it never needs
A file from outside a store should make you ask two questions: where it came from, and what it wants from the phone. Here are both answers for this build.
Where the file comes from
The only copy we publish sits on this page. Links pushed through chat groups are not ours, whatever name the file carries. Save this page address and come back to it whenever a new build is due.
Storage and alerts
The app needs room for its own files and, if you allow it, the right to send notifications. Both are reversible from the phone settings at any time. Nothing else on the device is touched, and the APK in Downloads can be deleted after the install.
Session and sign-out
A signed-in app keeps the account open until you close it. On a handset you share with family, sign out from the app menu every time you finish. The website offers the same control from the top bar.
What support will never ask for
No agent needs your bKash PIN, your one-time code or your password, in the app or in live chat. Anyone who asks for those is not from us. Payments happen inside the wallet you already use, never inside a message thread.
When the install does not go through
Most failed installs come down to three things: an older copy still sitting on the phone, a browser that is not allowed to install, or a download that never finished. Match the message on your screen to a row below.
| What you see | Likely cause | What to do |
|---|---|---|
| App not installed | An older build of the app is still on the phone, and Android will not overwrite it. | Uninstall the old icon first, then open the new file from Downloads. Your sign-in details and balance do not change. |
| Blocked by Play Protect | Android flags every file that did not arrive through the Play Store. | Tap More details, check that the size reads 28 MB and the version 2.1.20, then choose Install anyway. |
| The download stops halfway | Data saver or a battery mode cut the connection partway through the transfer. | Switch to Wi-Fi, delete the partial file, and start again from this page. The 28 MB transfer needs a steady few minutes. |
| Install finishes, then the app closes | The phone runs an Android version older than 8.0. | Use the mobile browser instead. The lobby, cashier and games all work there with the same account and the same balance. |
| Sign-in keeps returning to the form | A typo in the number or password, or the session was cleared by a phone cleaner. | Sign in on the login page once, then open the app again from the icon. If the password is lost, reset it before retrying. |
123bdt App questions before you install
Is the 123bdt App APK safe to install?
The file on this page is the build we publish: 28 MB, version 2.1.20. Android shows a warning for any app installed outside the Play Store, and that warning is about the method, not about a fault in this file. Check the size before installing, and ignore copies sent through chat groups or shortened links.
Do I need to delete the old app before updating?
Usually no. Installing over the top keeps your sign-in and the icon keeps its place on the home screen. If the phone answers with App not installed, remove the old copy first, then install again and sign in with the same registered number.
Why does the phone warn about harmful files?
That screen appears for every app that arrives outside the store, whatever the app is. Read the file size and the version number first, then continue if both match the table above. If you are not sure yet, cancel and play a session in the browser instead. Nothing is lost.
Can I install it on an iPhone?
No. There is no iOS build, and an Android file will not run on an iPhone. Safari users can add the site to the home screen instead, which gives a full screen icon plus the same account, cashier and games without any install step.
Does the app work on mobile data?
Yes, and it uses less data than the full site, which helps on a weak signal. The first sign-in and every deposit still need a steady connection, so keep the wallet step on Wi-Fi if the mobile link keeps dropping. Live tables take more data than slots.
How do I update when a new build appears?
Come back to this page, compare the version in the table with the one on your phone, and install the newer APK over the old copy. Nothing needs removing and your balance stays where it was. The version number and the update date here always match the file we serve.
Where do I get help if the install keeps failing?
Live chat runs 24/7 and the team can walk you through the unknown sources setting screen by screen. Tell them your phone model and the exact message you see on the screen. Never send your password or your wallet code to anyone, including someone who says they are from support.
The icon is the last step. Create an account, send your first deposit through bKash or Nagad, and the 135% welcome bonus up to ৳13,000 applies once you start playing.
