PAYMENT RAILS

Local Payment Methods We Accept

Deposits and withdrawals on ok400 run through the mobile wallets Bangladesh players already use every day. To deposit, open your wallet app, select send money, enter the account number shown in the cashier, and confirm with your PIN — the amount typically appears in your ok400 wallet within a short time after confirmation. Withdrawal requests go through a verification step before funds are sent back to your wallet. Availability depends on your region and local regulations.

HELP CHANNELS

Reach Us When You Need a Hand

Support for your ok400 account runs across three channels depending on how urgent the question is. Deposit confirmations, game round disputes and login issues are fastest through live chat. Formal account queries — identity verification, withdrawal holds — work better over email because you can attach documents and keep a written record. Mobile users get the same full support access as desktop; there's no reduced-capability version of the help system when you're on your phone.

Live Chat Open the chat widget from any page in the lobby — it connects you to a support agent for real-time help with deposits, game loading errors or account access. Response times are shorter during peak hours.
Email Support Send account or withdrawal queries to our support address listed in the contact section of the footer. Email is the right channel when you need to share screenshots or account documents; we reply with a written record you can refer back to.
Mobile Help Access The support widget and email link work identically in a mobile browser — no desktop needed to raise a query. If your bKash or Nagad deposit hasn't reflected, you can open a chat directly from the cashier screen on your phone.
ANY SCREEN

Phone, Tablet or Desktop

The ok400 lobby loads in your mobile browser without an app install, and the same account works on desktop when you want a bigger screen.

Get Into the Lobby Fast

Opening your ok400 account takes a handful of steps on your phone. Once you're in, the lobby menu shows every category — slots, live tables and sports — across the top bar so you can switch without going back to a home screen. If anything's unclear during setup, live chat is reachable directly from the login page. Bangladesh players can access ok400 where local law and eligible regions permit.

Create Your Account Hit the sign-up button, enter your mobile number and a password, and confirm the OTP sent to your phone. The whole process runs inside your browser — no app download needed to get started.
Your Account Wallet Every deposit and withdrawal moves through your account wallet. You can see your current balance, transaction history and pending cashouts from the wallet tab — check it after each deposit to confirm the amount landed.
What's Available in the Lobby The main lobby covers casino slots including Gates of Olympus and Mahjong Ways, live tables from Evolution, crash games like Aviator, and a sportsbook where cricket — BPL, international matches — sits at the front of the sports list.
Help When You Need It If your deposit hasn't reflected or you have a question about a game round, live chat connects you to the support team. You can also reach us by email for account or withdrawal questions that need a written trail.

ACCOUNT SECURITY

How We Keep Your Account Safe

Security on ok400 works in layers — the connection, the login, the transaction record and the way your personal data is handled each have a distinct protection in place. None of these steps adds friction to normal play; they run quietly in the background so you can move between the lobby and your wallet without interruption. If you ever spot something unusual in your account history, contact support immediately and we'll review the activity with you.

Encrypted Connection Every page on ok400 — including the cashier and account settings — is served over SSL, so data moving between your device and our servers is encrypted in transit and cannot be read in plain text.
Login and OTP Verification When you log in from a new device or request a sensitive account action, we send a one-time password to your registered mobile number.
Transaction Records Every deposit and withdrawal generates a timestamped record in your account wallet. You can review the full history at any time under the transactions tab — each entry shows the method used, the amount and the status, so nothing is…
Data Handling Your personal details and payment information are stored with access controls that limit which systems can read them.

HOW WE WORK

Transparency Behind the ok400 Platform

We document what we offer so you can make an informed decision before opening an account. Game RTP data comes directly from the provider and is shown on the title only when the studio publishes it — we don't estimate or fabricate those figures. Our terms, privacy policy and responsible account use documents are linked in the site footer and kept current whenever our conditions change. If something on the site contradicts what you expect, contact our support team directly and we'll clarify in writing.

Game Documentation

Each game in our lobby carries the provider's published rules and, where available, the RTP figure supplied by that studio — Pragmatic Play and PG Soft titles, for example, publish this data on the game card.

Policy Access

Our terms of use, privacy notice and cookie policy are accessible from the footer on every page. We update them when conditions change and note the revision date at the top of each document.

Contact Routes

You can reach us through live chat for urgent questions or by email for account and payment matters. Both channels are staffed; we don't route your query through an automated reply for account-specific issues.

Content Currency

Lobby content, promo details and payment method availability are reviewed regularly. If a game studio or payment rail changes its offering, we update the relevant section rather than leaving outdated information in place.

LOBBY NAVIGATION

Switch Between Casino, Slots and Sportsbook

The ok400 lobby is laid out so you can move between game categories without going back to a home screen each time. The top navigation bar carries tabs for Live Casino, Slots, Crash Games and Sportsbook — tap or click any tab and the relevant room loads in the same page. Use the search bar inside the slots room to find a specific title like Gates of Olympus or Teen Patti DreamPlay by name. To reach your account area — wallet, transaction history, profile settings — tap the account icon in the top-right corner; it's the same position on mobile and desktop.

Finding a Specific Game

Type the game name into the search bar inside the lobby — titles like Crash Zap, Aviator and Roulette Royale surface immediately. Filter by provider if you want to browse everything from a single studio like PG Soft.

Switching to Live Casino

Tap the Live Casino tab and the room shows streamed tables grouped by game type — baccarat, roulette, Dragon Tiger and Teen Patti tables are listed separately so you can jump to your preferred format without scrolling the full grid.

Opening the Sportsbook

The Sportsbook tab sits next to Casino in the top bar. Cricket markets — including BPL and international fixtures — are listed at the top of the sports menu by default, reflecting what Bangladesh players open first.

Your Account Area

The account icon opens your wallet balance, deposit and withdrawal screens, and your personal settings. From here you can also check active offers without navigating away from the game section you were in.
