Join ok400 and Access the Full Lobby
Creating your ok400 account takes just a few steps — enter your details, verify your mobile number, and your wallet connects to bKash, Nagad, or Rocket straight away. Access is subject to your local law and eligible regions.
Browse Your Payment Choices at ok400
Your account wallet connects to the payment methods you already use every day. bKash, Nagad, and Rocket all appear in the deposit section the moment your account is active. Open your preferred app, send to the account number shown on the deposit screen, confirm with your PIN, and the balance reflects in your ok400 wallet. Withdrawals follow the same path in reverse — request from the wallet section, and the amount moves back to your mobile wallet through the same rail you deposited with.
bKash
Send from your bKash app to the number shown on the deposit screen. Confirm with your PIN and the balance appears in your ok400 wallet.
Nagad
Open Nagad, enter the ok400 account number, add your amount, and confirm. Your wallet updates once the transfer clears on the Nagad network.
Rocket
Use Rocket's send-money flow — enter the deposit number from your wallet page, confirm the amount and PIN, and your ok400 balance is updated.
Explore What Happens When You Register
The registration form asks for your name, a working mobile number, and a password you choose yourself. Once you submit, an OTP arrives on your phone — enter it to confirm your number, and your account is active. From there, you head straight into the lobby: live casino tables, slots including Crash Zap and Teen
Patti Luck, and the sportsbook where cricket markets are listed. Your first deposit link appears in the wallet section, where bKash, Nagad, and Rocket are already set as the default options. If anything looks unclear, our support channel is reachable through the help icon on every page.
-
OTP Verification We confirm your mobile number via a one-time code sent immediately after you submit the form — no email chain, no waiting on a call.
-
Account Security Your password is stored encrypted. We also flag unusual login attempts on the account so you can review them from your profile settings.
-
Lobby Navigation After verification, the lobby opens with live tables, slots, and sports in separate tabs. Switch between them without losing your wallet session.
-
Support Access A help icon sits on every page of the account area. Tap it to reach our Bangladesh support channel — useful if your OTP or wallet link needs attention.

See How ok400 Protects Your Account
Account security is built into the registration flow, not bolted on after the fact. From the moment you submit your details, the data moves over an encrypted connection. Identity verification happens through your mobile OTP rather than manual document uploads, keeping the process quick while confirming the number belongs to you. Your personal data is held under our privacy policy and is not shared with third parties outside of what is required to process payments through bKash, Nagad, or Rocket.
Every page on ok400, including the registration form, runs over an SSL-encrypted connection. Your details travel securely from your device to our servers.
We verify your identity through a one-time code sent to your registered mobile number — confirming the account belongs to you without needing physical documents.
Account access on ok400 is available only to eligible adults in supported regions. Availability depends on your local law and the region your account is registered from.
Your registration data is stored under our privacy policy. We only pass payment details to bKash, Nagad, or Rocket as needed to process your wallet transactions.
Get Help With Your Registration
If something stalls during sign-up — an OTP that doesn't arrive, a wallet link that needs a second look, or a password reset — our support paths are built into the account area so you don't need to search for help separately. Reach us through the help icon, live chat, or the contact form, depending on what suits your situation.
Live Chat
Tap the chat icon from the registration page or your account area. Describe the issue — OTP, wallet, or login — and the team picks it up directly.
Contact Form
Fill in the form with your registered mobile number and a short description of the problem. Useful when you need to attach a screenshot of a wallet step.
Help Centre
The help section inside your account covers common registration steps — OTP not received, changing your mobile number, and linking a second wallet method.
Common Questions About Signing Up
These are the questions we hear most often from people going through the registration flow for the first time. If your question isn't here, the help centre inside your account covers additional account and wallet topics.
