Running into occasional hiccups on an online betting platform is completely normal. Maybe a deposit didn't go through, you can't log in, or a bonus hasn't shown up in your account — when that happens, knowing where to turn matters. That's exactly what the tk665 Help Center is here for.
Our support team is made up of experienced Bengali-speaking agents who can help you in your own language. Whether you're in Dhaka, Rajshahi, Chittagong, or Khulna — wherever you are, Bengali support is available. We don't give you the runaround with technical jargon — our goal is to get your problem sorted, straight and simple.
Every day, hundreds of thousands of users play, bet, and transact on tk665. At that scale, the occasional issue is inevitable. But when problems get resolved quickly, the overall experience stays smooth — that's why we're active 24 hours a day, 7 days a week.
Below is a quick list of the questions our support team receives most often. Most of these you can resolve on your own.
Contact support with your transaction number. Most issues are resolved within 15 minutes.
On the login page, select "Forgot Password" and enter your mobile number.
Check whether the bonus conditions have been met. If not, contact support.
Uninstall the app and download the latest version. If the issue persists, let us know.
When contacting support, have your registered mobile number and a description of the issue ready. If you have a screenshot, send it along — it helps us resolve things faster.
Signing up with tk665 only requires an active mobile number. Go to /register, enter your number, send the OTP, confirm — and your account is ready. The whole process takes under 30 seconds.
Click the "Forgot Password" link on the login page. An OTP will be sent to your registered mobile number — use it to set a new password. Your password must be at least 8 characters long and include at least one number.
Log in to the app or website and go to "My Profile." You can update your name, email, and address there. To change your mobile number, please contact support.
Large withdrawals may require KYC verification. Simply upload a photo of your National ID or passport. Verification is typically completed within 24 hours.
Go to the Wallet section and select Deposit, then choose bKash. Enter the amount and number, then submit. Confirm the OTP in your bKash app. Funds are added instantly.
Go to "Withdrawal" in your wallet. Enter the amount and your bKash/Nagad number. Funds usually arrive within 5–15 minutes. Minimum withdrawal is ৳200.
If money was deducted but hasn't appeared in your account, don't panic. Note down the transaction ID and contact live chat. Our team will manually verify it and resolve the issue within 30 minutes.
Tk665 currently supports bKash, Nagad, Rocket, Visa & Mastercard, and direct bank transfer. The minimum deposit is just ৳50, with no transaction fees.
Tk665 uses decimal odds. For example, odds of 1.85 mean a ৳100 bet returns ৳185 if you win (৳85 profit). The higher the odds, the lower the chance of winning — but the bigger the reward.
To place live bets during a match, go to the "Live" section. Odds update every few seconds, so make your decisions quickly — they can change at any moment.
Once a bet is confirmed, it generally cannot be cancelled. However, some bets offer a "Cash Out" option, which lets you take a partial payout before the match ends.
Go to "Betting History" in your profile to see full details of all past and active bets. You can also filter by date or game to find specific entries.
Download the APK file from the downloads page. Before installing, go to your phone's settings and enable "Install from unknown sources." Once installation is complete, you can turn that setting back off.
IPhone users, open the tk665 website in Safari and tap "Add to Home Screen." This gives you an app-like experience without a separate download.
Check your current version under "Settings" in the app. If a newer version is available, download it from the downloads page. You can install the new APK without uninstalling the old one first.
Start by restarting your phone. If that doesn't help, clear the app cache. If the problem still isn't resolved, uninstall and reinstall the latest version. If you're still experiencing issues after that, contact support.

Our support team does more than just fix problems — they can help you get more out of your betting experience. Whether you want to know which bets work best for a particular match, how different odds compare, or how parlay bets work, just ask us on live chat.
Tk665 believes an informed player makes the best decisions. That's why our Help Center covers not just technical guides, but also responsible gaming — including how to set a budget, when to take a break, and how to set limits. Every player should know this.
A lot of people assume contacting support is a hassle. At tk665, it's the opposite. Live chat is just one click away, and within minutes a real person is ready to hear you out — no robotic auto-replies, no long queues, just a straight conversation with a human.
Tk665 takes security seriously and never compromises on it. If you notice any unusual activity on your account, contact us immediately and we'll investigate promptly. We will never ask for your account details over the phone or chat — if anyone does, it's a scam. Please report it to us right away.
Mobile network speeds vary across Bangladesh. In rural areas, slower connections can sometimes delay payment transactions. In such situations, contact support before trying again — multiple simultaneous transactions can complicate things.
