Your First Deposit Bonus: How It Works

Every new ob55 account qualifies for the welcome bonus automatically. Deposit at least ৳450, and the platform adds 115% on top — giving you extra funds to explore slots, live casino, and cricket markets from day one.

What Information Do You Need to Register?

ob55 keeps registration lean. You only need three mandatory pieces of information to open your account. No email address, no ID scan — until your first withdrawal triggers the KYC check.

Field Required? Format / Requirement Why It Matters
Mobile Number Yes BD number starting with 01, 11 digits (e.g., 01XXXXXXXXX) Linked to your bKash/Nagad wallet for deposits and withdrawals
Password Yes Minimum 8 characters; mix letters and numbers Protects your account; do not reuse passwords from other sites
Confirm Password Yes Must exactly match the password field Prevents typos that lock you out immediately
Referral Code Optional Alphanumeric code from a friend or promo link Triggers ৳500 referral bonus for you and your referrer
Terms Agreement Yes Checkbox — must be ticked before submitting Confirms you are 18+ and accept ob55's terms of service

KYC documents (NID, Passport, or Driving Licence) are only required before your first withdrawal. See the Withdrawal & KYC Guide for full details.

After You Register: First Deposit & Verification

Registration takes under three minutes. Once your account is live, these four steps get you from zero balance to bonus-active and ready to withdraw without delays.

Make Your First Deposit

Go to the Deposit page, choose bKash, Nagad, Rocket, Upay, or Bank Transfer, and send at least ৳450. Funds arrive in your ob55 wallet in about 5 minutes. Your 115% bonus is credited automatically.

Verify Your Mobile Number

A one-time SMS code confirms your phone number is real and matches your bKash/Nagad wallet. Enter it on the verification screen. If the code doesn't arrive within 2 minutes, tap "Resend."

Prepare KYC Documents Early

KYC is mandatory before your first cash withdrawal. Accepted documents: NID Card, Passport, or Driving Licence. Upload clear photos (not blurry, not cropped). ob55 reviews submissions within 24 hours.

Start Playing & Earning Cashback

Every bet, win or lose, earns daily cashback starting at 0.6%. Explore over 4,600 games from JILI, Pragmatic Play, Ezugi, Spribe, Playtech, and CQ9. Cricket and live casino markets are open 24/7.

Step-by-Step: How to Complete ob55 Registration

Follow these four steps in order. If you skip the KYC step now, you can still play — but you will need to complete it before you request your first withdrawal.

  1. 1

    Fill in the Registration Form

    Enter your 11-digit Bangladesh mobile number (starting with 01) in the form at the top of this page. Create a password with at least 8 characters mixing letters and numbers. Re-enter it in the Confirm Password field to avoid typos. If a friend gave you a referral code, paste it in the optional Referral Code box to unlock your mutual ৳500 bonus. Tick the Terms checkbox — you must be 18 or older to register.

  2. 2

    Verify Your Mobile Number via SMS

    After you tap "Register Now," ob55 sends a 6-digit OTP to your phone. Enter it on the verification screen within 5 minutes. The OTP is single-use and expires quickly, so keep your phone nearby. If you do not receive the code within 2 minutes, tap "Resend OTP" once. Still nothing? Check that the number you entered matches your active SIM card.

  3. 3

    Make Your First Deposit via bKash or Nagad

    Log in to your new account and go to the Deposit section. Select your preferred method — bKash, Nagad, Rocket, Upay, or Bank Transfer. Enter an amount of at least ৳450. Follow the payment screen instructions on your phone. The funds, plus your 115% welcome bonus (up to ৳15,000), appear in your wallet within about 5 minutes. Keep your bKash/Nagad transaction ID handy in case you need to contact support.

  4. 4

    Upload KYC Documents Before Your First Withdrawal

    ob55 requires identity verification before releasing any cash withdrawal. Go to Account > KYC, upload a clear photo of your NID Card, Passport, or Driving Licence. The review team responds within 24 hours. First-time withdrawals may take up to 6 hours to process after KYC is approved; subsequent withdrawals are typically done in about 4 minutes. The minimum withdrawal amount is ৳900; the daily cap is ৳95,000.

Common Registration Errors — and How to Fix Them

Most ob55 registration problems take under a minute to fix. Here are the five issues players encounter most often, with the exact cause and solution for each.

Error / Problem Likely Cause Fix
"Mobile number already registered" That phone number has an existing ob55 account — possibly created earlier from another device or browser. Go to ob55 Login and use the Forgot Password option. Contact 24/7 Live Chat if you cannot recover access.
OTP code not received Wrong number entered, SIM card inactive, or carrier delay (can take up to 2 minutes on some networks). Wait 2 full minutes, then tap "Resend OTP." Double-check the mobile number on the form matches your active SIM. Try on a different network if the problem repeats.
OTP expired or "Invalid code" OTP codes expire after 5 minutes. Entering the wrong digits also triggers this error. Tap "Resend OTP" to get a fresh code. Enter it immediately. Do not close the browser tab while waiting — it resets the session.
"Passwords do not match" A typo in either the Password or Confirm Password field, or autocomplete filling in an old saved password. Clear both fields and type manually. Toggle the eye icon to show characters and confirm they are identical before submitting.
Page freezes or form won't submit Slow mobile data connection, browser cache issue, or JavaScript blocked by a VPN/firewall. Switch to a stable Wi-Fi connection (or mobile data if on Wi-Fi). Clear browser cache and cookies. Try a different browser (Chrome recommended). Disable any VPN. Download the ob55 App for a faster registration experience on Android.

Questions About the ob55 Register Process

Can I register with a Nagad number instead of bKash?
Yes. ob55 accepts any active Bangladesh mobile number for registration — it does not have to be a bKash number. You can link Nagad, Rocket, or Upay for deposits and withdrawals at any time after registration. The mobile number you register with simply becomes your account username, so use the number attached to whichever mobile wallet you plan to deposit from most often.
Is there a limit on how many ob55 accounts one person can open?
ob55 strictly allows one account per person, per household, and per device. Creating multiple accounts to claim the welcome bonus more than once is against the Terms & Conditions and will result in all accounts being suspended and balances voided. If you accidentally created a duplicate account, contact 24/7 Live Chat immediately to merge or close the extra account before making any deposit.
How soon does the 115% welcome bonus appear after I deposit?
The bonus is credited automatically within a few seconds of your first deposit being confirmed — usually the same 5-minute window as the deposit itself. You do not need to enter a promo code. If your bonus does not appear after 10 minutes, go to Account > Bonuses and tap "Claim." If it still does not show, contact Live Chat with your bKash/Nagad transaction reference number.
What happens if I forget my password before completing KYC?
Use the Forgot Password link on the ob55 Login page. Enter your registered mobile number and ob55 will send a password-reset OTP. Reset your password, then log in normally. KYC status is not affected by a password reset. If you no longer have access to that phone number, contact 24/7 Live Chat with your NID details to recover the account.
Do I need to complete KYC straight after registering?
No — you can register, deposit, claim your bonus, and play without uploading KYC documents. Identity verification is only required before your first cash withdrawal. That said, uploading your NID, Passport, or Driving Licence early (Account > KYC) is recommended so there is no delay when you are ready to withdraw. The review takes up to 24 hours, and your first withdrawal may take up to 6 hours after KYC is approved.
Can I register and play on my phone without downloading the app?
Yes. The ob55 website is fully mobile-optimised and works in any modern mobile browser — Chrome, Samsung Internet, Firefox. You can register, deposit, play, and withdraw entirely via the browser. For a smoother experience with push notifications and faster loading, the ob55 Android App (version 2.3.15, 58 MB, requires Android 6.0 or higher) is free to download directly from the ob55 website.
