Account & Registration

Registering on koko300 is free and takes about two minutes. Go to koko300.app/register, enter your mobile number, choose a password and submit. You will receive a verification code on your phone — enter it to activate your account. Once verified, you can log in, make your first deposit and start playing any koko300 game immediately. No documents are required to register.

Yes, completely free. There is no registration fee, no subscription charge and no hidden cost to create a koko300 account. You only spend money when you choose to make a deposit and place a bet. Creating an account simply gives you access to the platform.

Go to the login page and click "Forgot Password". Enter the mobile number linked to your koko300 account and you will receive a reset code by SMS. Enter the code, set a new password and you are back in. If you do not receive the SMS within two minutes, check that you entered the correct number and try again. Still stuck? Contact support at [email protected].

No. koko300 allows one account per person and per mobile number. Creating multiple accounts is against our Terms and Conditions and may result in all accounts being suspended and balances forfeited. If you have accidentally created a duplicate account, contact support immediately so we can resolve it without penalty.

Log in to your koko300 account and go to Account Settings. From there you can update your display name and notification preferences. To change your registered mobile number, you need to contact our support team at [email protected] for identity verification before the change is processed. This is to protect your account security.

You must be at least 18 years old to register and play on koko300. This is a strict requirement and applies to all game categories — fishing, slots, live casino and sports betting. koko300 is committed to responsible gaming and does not permit underage access. See our Responsible Gaming page for more information.

If you wish to close your account, email [email protected] with your registered mobile number and a request to deactivate. Our team will process the request within 24 hours. Any remaining balance will be returned to your bKash or Nagad account before closure. You can also use the self-exclusion option in Account Settings if you need a temporary break from gaming.

Yes. koko300 uses 256-bit SSL encryption on all data transmissions. Your personal information is never sold or shared with third parties for marketing purposes. All data handling follows our Privacy Policy. Payment details are processed through secure mobile banking channels and are not stored on koko300 servers.
Deposits & Withdrawals

koko300 supports bKash, Nagad and Rocket for both deposits and withdrawals. These are the most widely used mobile banking services in Bangladesh, so most players can fund their account without needing a traditional bank account. All three methods are available directly inside the koko300 platform — no need to open a separate app or copy account numbers manually.

Deposits via bKash and Nagad are processed in under two minutes in most cases. Once you confirm the payment with your mobile banking PIN, the amount is credited to your koko300 balance automatically. If your balance has not updated after five minutes, refresh the page or contact support with your transaction reference number.

The minimum deposit on koko300 is ৳100. This low entry point means you can start playing fishing games, slots or live casino tables without committing a large amount. There is no maximum deposit limit for standard accounts, though very large deposits may require additional verification for security purposes.

Go to your koko300 account, select Withdraw, choose bKash, Nagad or Rocket, enter the amount and confirm. The funds are sent directly to your mobile banking account. Most withdrawals are processed within 15 to 30 minutes. During peak hours it may take up to two hours. The minimum withdrawal amount is ৳200. Make sure the mobile number on your koko300 account matches the one registered with your mobile banking service.

koko300 does not charge any platform fees for deposits or withdrawals. However, your mobile banking provider (bKash, Nagad or Rocket) may apply their standard transaction charges. These are set by the mobile banking service and are outside koko300's control. Check your bKash or Nagad app for their current fee schedule.

First, wait five minutes and refresh your koko300 balance. If it still has not updated, take a screenshot of your bKash or Nagad transaction confirmation showing the reference number, amount and time. Send this to [email protected] and our team will manually verify and credit your account within one hour. Do not make a second deposit until the first one is resolved.

No. For security reasons, withdrawals can only be sent to the mobile number registered on your koko300 account. This prevents unauthorised withdrawals if someone else gains access to your account. If you need to update your registered number, contact support at [email protected] before requesting a withdrawal.
Games & Bonuses

koko300 offers six main game categories: fishing games (Fierce Fishing and Cannon Fishing), slots (Fortune Tiger), live casino (WM Live with baccarat, roulette and dragon tiger), sports betting (Football) and arcade games (Tower). All games are accessible from one account and one wallet. Visit the Game page for the full library.

The welcome bonus is applied automatically when you make your first deposit after registering. You do not need to enter a promo code. The bonus is credited to your account balance and can be used on any koko300 game — fishing, slots, live casino or football betting. Check the current bonus terms in your account dashboard after registering, as bonus amounts and conditions may be updated periodically.

All koko300 games use certified Random Number Generator (RNG) systems that are independently tested. Game outcomes cannot be predicted or manipulated by the platform or by other players. RTP (Return to Player) percentages are published openly — for example, Fortune Tiger has a confirmed 96.8% RTP. The platform uses 256-bit SSL encryption and all game data is logged and auditable.

Minimum bets vary by game. Fortune Tiger starts from ৳5 per spin. Fierce Fishing and Cannon Fishing start from ৳10 per round. Tower starts from ৳10. WM Live tables start from ৳20 per hand. Football betting starts from ৳20 per bet slip. These low minimums make koko300 accessible for casual players who want to enjoy the games without large stakes.

Some koko300 games offer a demo or experience mode where you can try the game mechanics without using real money. Visit the Experience page to see what is currently available in demo mode. To play for real winnings and access the full game features, you will need to make a deposit. The minimum deposit is ৳100.

Tower is an arcade-style game where you place a bet and then choose to climb levels. Each level you survive multiplies your stake. You can cash out at any point and collect your winnings, or keep climbing for a higher multiplier. If you hit a losing tile, you lose your bet for that round. The game is fast, simple and entirely skill-based in terms of when you decide to stop. It is one of the most popular games on koko300 right now.

Yes. koko300 Football supports both pre-match and live in-play betting. You can place bets while a match is in progress, with odds updating in real time as the game develops. Markets include Asian handicap, over/under, match result, both teams to score and more. Leagues covered include Premier League, La Liga, Champions League, Serie A and Bangladesh national fixtures.
App & Technical

Yes. The koko300 Android app is available for direct download from koko300.app/app. The APK file is 18MB and installs in under a minute on any Android phone running version 6.0 or above. iOS users can open koko300.app in Safari and tap "Add to Home Screen" for a full-screen experience without needing an App Store download. The app and mobile browser version offer identical features.

koko300 is optimised for the devices most commonly used in Bangladesh — Samsung Galaxy, Xiaomi, Realme, Oppo and Symphony. The platform runs on Grameenphone, Robi, Banglalink and Teletalk 4G networks. Games are designed to load in under three seconds and run without lag even on budget Android phones. A stable 3G or 4G connection is recommended for WM Live streaming.

Android phones block APK files from unknown sources by default. To install the koko300 app, go to your phone's Settings → Security → Install Unknown Apps and allow your browser to install APK files. Then re-download the APK from koko300.app/app and tap to install. If you still have issues, try clearing your browser cache and downloading again, or contact support at [email protected].

Slow loading is usually caused by a weak internet connection. Switch from Wi-Fi to mobile data or vice versa and try again. If the issue persists, clear your browser or app cache, close background apps to free up RAM and reload. For WM Live streaming, a 4G connection is strongly recommended. If a specific game is consistently slow for you, report it to [email protected] with your device model and network provider.

Our support team is available 24 hours a day, 7 days a week. You can reach us via live chat inside the koko300 app or platform, or by email at [email protected]. Live chat responses are typically within a few minutes. Email responses are within one hour during normal hours and within two hours overnight. Please include your registered mobile number and a description of the issue when contacting support.
