1 Acceptance of Terms
These Terms and Conditions ("Terms") constitute a legally binding agreement between you ("Player", "User", "you") and tk688 ("tk688", "the Platform", "we", "us", "our") governing your use of the tk688 website accessible at tk-688.bio, all associated subdomains, mobile-optimised interfaces, and any services, features, or content offered through the platform.
By creating an account, making a deposit, placing a bet, participating in a promotion, or otherwise accessing any feature of tk688, you acknowledge that you have read these Terms in full and agree to comply with them. This agreement takes effect from the moment you first access the tk688 platform and remains in effect for the duration of your account's existence.
tk688 reserves the right to update, amend, or replace these Terms at any time. Continued use of the platform following the publication of any revised Terms constitutes your acceptance of those changes. It is your responsibility to review these Terms periodically. The date of the most recent revision is displayed at the top of this page.
2 Eligibility & Age Restriction
To be eligible to register and use the tk688 platform, you must satisfy all of the following conditions at the time of registration and at all times during the use of your account:
- You are at least 18 years of age.
- You are a natural person and not a corporation, trust, partnership, or other legal entity.
- You are accessing the platform voluntarily and on your own behalf.
- You are not registered on any self-exclusion list maintained by tk688 or any affiliated responsible gaming programme.
- You have not previously had an account closed or suspended by tk688 for any breach of these Terms.
- You have the legal capacity to enter into a binding agreement under the laws applicable in your jurisdiction.
tk688 reserves the right to request identity verification documents at any time to confirm age eligibility. Where age verification cannot be completed to tk688's satisfaction, the account will be suspended and any pending withdrawals withheld pending resolution. tk688 takes its age verification obligations seriously and co-operates with any lawful request to prevent underage gambling.
3 Account Registration
Each player may hold only one (1) registered account on tk688. The creation of multiple accounts by a single individual — whether using different names, email addresses, mobile numbers, payment methods, or device identifiers — is strictly prohibited and constitutes a material breach of these Terms. Where multiple accounts are identified as belonging to the same individual, tk688 reserves the right to close all such accounts, void all associated bets and bonuses, and withhold or return deposits at its discretion.
When registering, you are required to provide accurate, current, and complete information. This includes your full legal name, date of birth, valid mobile number, and any other details requested during the registration process. You are solely responsible for maintaining the accuracy of your account information. tk688 accepts no liability for losses arising from inaccurate or outdated account details provided by the player.
You are responsible for maintaining the confidentiality of your account credentials, including your username and password. You must not share your login details with any third party. Any activity carried out through your account — whether or not authorised by you — is your sole responsibility. If you suspect unauthorised access to your account, you must notify tk688 support immediately via live chat.
4 Deposits & Withdrawals
All transactions on the tk688 platform are conducted exclusively in Bangladeshi Taka (BDT, ৳). tk688 supports the following payment methods for both deposits and withdrawals: bKash, Nagad, Rocket, and Upay. tk688 does not currently accept international payment cards, bank wire transfers, or cryptocurrency transactions.
The minimum deposit amount is ৳200. Deposits are credited to your tk688 balance in real time upon confirmation from the relevant mobile financial service provider. tk688 does not charge any fee on deposits; however, your mobile wallet provider may apply its own transaction fees, for which tk688 accepts no responsibility.
The minimum withdrawal amount is ৳500. Withdrawal requests from verified accounts are processed within 5 to 15 minutes during normal operating conditions. Processing times may be extended during periods of high transaction volume, scheduled maintenance, or where additional verification is required. Withdrawals are paid exclusively to the same mobile wallet account used for the most recent deposit, unless an alternative has been formally approved by tk688's payment team following a verification review.
tk688 reserves the right to request supporting documentation — including a copy of a government-issued photo ID and proof of payment method ownership — before processing any withdrawal. This is a standard anti-money-laundering measure and is applied without prejudice. Failure to provide requested documentation within the specified timeframe may result in the suspension of the withdrawal request.
- Deposits must originate from a payment account registered in the player's own name.
- Third-party deposits are strictly prohibited and will be returned to the source account.
- tk688 reserves the right to impose daily, weekly, or monthly deposit and withdrawal limits at its discretion.
- Any funds identified as proceeds of fraudulent activity will be frozen and reported to the relevant authorities.
5 Bonuses & Promotions
tk688 offers a range of promotional bonuses to both new and existing players, including but not limited to welcome deposit bonuses, reload bonuses, free bet credits, cashback offers, and seasonal promotions tied to events such as the BPL, IPL, T20 World Cup, Eid, and Pohela Boishakh. All bonuses are subject to the specific terms published at the time the promotion is offered, which form part of these Terms by reference.
Unless otherwise stated in the promotion-specific terms, the following general conditions apply to all bonuses offered by tk688:
- Bonuses are available to one account per player, per household, and per device.
- Bonus funds carry a wagering requirement. The applicable wagering multiplier will be stated in the promotion details. Bonus funds and any winnings derived from bonus funds may not be withdrawn until the wagering requirement has been satisfied in full.
- Wagering requirements must be completed within the timeframe specified in the promotion. Unmet wagering requirements will result in the cancellation of the bonus and any associated winnings.
- tk688 reserves the right to withdraw, modify, or cancel any promotional offer at any time, including where abuse or exploitation of a promotion is suspected.
- Players who are found to have exploited bonus terms — including through the use of multiple accounts, systematic low-risk betting patterns designed to clear wagering requirements, or collusion — will forfeit all associated bonus funds and may have their accounts closed.
6 Betting & Gaming Rules
All bets placed on the tk688 sportsbook and all wagers made on tk688 casino games are subject to the specific rules of the relevant game or market, as displayed within the platform at the time of play.

In all such cases, the voided stake will be returned to the player's account balance.
All casino games available on tk688 — including live dealer games provided by Evolution Gaming, Ezugi, and Pragmatic Play Live, and slot titles from Pragmatic Play, NetEnt, Microgaming, and other certified providers — are governed by the rules of the relevant game studio. tk688 does not control the outcome of any game and is not liable for losses arising from normal gameplay variance.

Players may also voluntarily close their account at any time by contacting tk688 support via live chat. Upon voluntary closure, any remaining balance in the account will be processed for withdrawal to the player's registered mobile wallet, subject to the completion of any outstanding verification requirements. Bonus funds not yet converted to withdrawable funds through wagering will be forfeited upon voluntary closure.
Where an account is closed by tk688 due to a confirmed breach of these Terms, tk688 reserves the right to withhold the account balance pending investigation. Where fraud or money laundering is confirmed, tk688 will report the matter to the appropriate authorities and will not return funds that are the subject of the investigation.
