Last Updated: January 2026

1. Introduction

These Terms and Conditions ("Terms") constitute a legally binding agreement between you ("Player", "User", or "you") and oktk4 ("oktk4", "we", "us", or "our") governing your access to and use of the oktk4 online casino and sports betting platform, including all games, services, promotions, and features made available through the site at https://oktk4.vip and any associated mobile or web applications.

By accessing the oktk4 platform, creating an account, making a deposit, or participating in any game or betting market, you acknowledge that you have read these Terms in their entirety, that you understand them, and that you agree to be bound by them. If you do not agree to these Terms, you must not access or use the oktk4 platform. oktk4 reserves the right to update or revise these Terms at any time. Continued use of the platform following the publication of any amendment constitutes acceptance of the revised Terms.

Important: These Terms include provisions governing dispute resolution, limitation of liability, and account suspension. Players are strongly encouraged to read every section carefully before using the oktk4 platform.

2. Eligibility

Access to the oktk4 platform and all games, betting markets, and services available on it is strictly limited to individuals who meet all of the following eligibility requirements. oktk4 enforces these requirements at registration and throughout the lifetime of each account. Attempting to circumvent any eligibility requirement is grounds for immediate account suspension and forfeiture of any associated balance.

  • You must be at least 21 years of age. This is a strict minimum — players under 21 are not permitted to register or use any feature of the oktk4 platform under any circumstances.
  • You must have the legal capacity to enter into a binding contract under the laws applicable to you. Persons who lack legal capacity to contract may not register or use the platform.
  • You must register only one account per person. Operating multiple accounts, whether under your own name or under another identity, is strictly prohibited and will result in immediate closure of all associated accounts and forfeiture of all balances.
  • You must provide accurate, truthful, and complete information when registering your account. oktk4 may request verification of the information you provide at any time.
  • You must not be a current employee, contractor, officer, or director of oktk4, nor an immediate family member of any such person, unless you have received prior written approval from oktk4 management.

3. Account Registration and Security

To access the games, betting markets, and other features of the oktk4 platform, you are required to create a personal account. Account registration is free of charge. You must provide a valid mobile number and choose a password during registration. Your mobile number serves as your primary login identifier on the platform.

You are solely responsible for maintaining the confidentiality of your account credentials, including your mobile number, password, and any other login information. You must not disclose your login credentials to any third party. oktk4 will never ask for your password via any communication channel. Any activity that occurs under your account credentials is your sole responsibility, whether or not you authorised that activity.

  • You must notify oktk4 support immediately at [email protected] if you suspect that your account has been accessed by an unauthorised third party.
  • oktk4 reserves the right to verify your identity at any point by requesting supporting documents. Failure to complete verification may result in account restrictions or suspension.
  • oktk4 may set cooling-off periods or waiting periods before processing withdrawal requests as part of our anti-fraud and security procedures. These periods will be communicated to you when applicable.
  • Each player may hold only one active account. If you have forgotten your login credentials, you must use the account recovery function on the oktk4 Login page rather than creating a new account.

4. Deposits and Withdrawals

All financial transactions on the oktk4 platform, including deposits and withdrawals, are conducted in Bangladeshi Taka (BDT). oktk4 does not support USD, EUR, or any other currency denomination. There are no currency conversion fees. The minimum deposit amount is ৳200. There is no maximum deposit limit, though individual payment method providers may impose their own limits which are outside of oktk4's control.

Withdrawals are processed to the same payment method used to make the most recent deposit. oktk4 does not process withdrawals to third-party accounts, bank accounts belonging to other individuals, or payment methods not previously used on the account. Processing times vary by payment method but are typically completed within 15 minutes for mobile wallet withdrawals (bKash, Nagad, Rocket) during normal operating hours.

  • Deposits are credited to your oktk4 account balance in BDT within seconds of a successful transfer from your bKash, Nagad, Rocket, or Upay mobile wallet.
  • oktk4 reserves the right to request supporting documentation before processing a withdrawal request, including but not limited to proof of identity and proof of ownership of the payment method being used.
  • Any bonus funds or free spin winnings credited to your account are subject to the applicable wagering requirement before they may be converted to real-money withdrawable funds. Attempting to withdraw bonus funds before meeting the wagering requirement will result in forfeiture of the bonus balance.
  • oktk4 does not charge transaction fees on deposits or withdrawals. Any fees charged by your payment provider (bKash, Nagad, Rocket, etc.) are outside of oktk4's control and are the player's responsibility.
  • oktk4 reserves the right to carry out enhanced due diligence checks on accounts and transactions that display unusual activity patterns. Accounts flagged during these checks may be temporarily restricted pending review.

5. Bonuses and Promotions

oktk4 offers a range of bonuses and promotional offers to new and existing players. All bonuses and promotions are subject to specific terms and conditions, including wagering requirements, rollover conditions, eligible games, and time limits. These specific terms are communicated alongside each bonus offer and form part of these Terms. In the event of any conflict between the specific bonus terms and these general Terms, the specific bonus terms shall prevail.

oktk4 reserves the right to modify, suspend, or cancel any bonus or promotion at any time without prior notice. Any such modification will not affect bonuses already validly claimed and in the process of being wagered. Players are responsible for reading the specific terms of each offer before claiming.

6. Gameplay and Betting Rules

All games made available on the oktk4 platform are operated using certified RNG (Random Number Generator) systems that are independently audited for fairness. The outcome of every game round — every spin, every card dealt, every crash multiplier — is determined by these independently verified RNG systems and is not influenced or controlled by oktk4 or any other party.

For sports betting markets, including cricket (BPL, IPL, T20 World Cup, Bangladesh Tigers matches), football, and kabaddi, odds are set and updated in real time by the oktk4 trading team. Bets placed and accepted by the platform are binding. oktk4 reserves the right to void bets that were placed on the basis of manifestly incorrect odds, technical errors, or any event that subsequently renders the settlement of a bet impossible or unfair.

  • oktk4 reserves the right to impose minimum and maximum bet limits on any game or market at any time. Current limits are displayed within the relevant game or betting market interface.
  • In the event of a technical failure during a game round — including disconnection, server error, or platform outage — oktk4 will make reasonable efforts to resolve the round fairly based on available data. Where this is not possible, the affected bet will be voided and the stake returned to the player's account.
  • Game results displayed on the oktk4 platform are final once a round is completed and settled. oktk4 does not accept requests to amend settled game results except in cases where an acknowledged technical error is demonstrated to have directly affected the outcome.
  • Players are responsible for understanding the rules of each game before placing a wager. Game rules are available within each individual game interface on the oktk4 platform.

7. Responsible Gaming

oktk4 is committed to promoting responsible gaming and to helping players who may be experiencing difficulties related to their gambling activity. The platform strictly enforces a minimum age requirement of 21 years. Any player who is found to have misrepresented their age during registration will have their account closed immediately, all winnings forfeited, and all deposited funds returned minus any applicable processing costs.

Players may request the following responsible gaming tools directly from within their account or by contacting support: deposit limits (daily, weekly, or monthly), session time limits, cooling-off periods, and self-exclusion. Self-exclusion requests are processed within 24 hours and may not be reversed during the exclusion period. oktk4 takes self-exclusion requests seriously and will not send promotional communications to self-excluded players.

21+ Only: oktk4 is an adult platform. If you believe that someone under the age of 21 is using the platform, please contact us immediately at [email protected]. We take underage gambling extremely seriously and act on all reports promptly.

8. Prohibited Activities

The following activities are strictly prohibited on the oktk4 platform. Engaging in any prohibited activity will result in immediate account suspension, forfeiture of all balances, and may be reported to relevant authorities where applicable.

  • Using the platform in a way that constitutes, facilitates, or assists any form of money laundering, fraud, or financial crime.
  • Registering more than one account, or using another person's account credentials to access the platform.
  • Using automated software, bots, scripts, or any other tool to interact with the platform in a way not intended for human players, including the scraping of odds data or the automated placement of bets.
  • Exploiting technical errors, software bugs, or platform vulnerabilities to gain an unfair advantage. Any winnings generated through exploitation of a known or discovered error must be reported to support and will be voided.
  • Depositing funds derived from criminal activity or using a payment method that does not belong to you. oktk4 requires all deposits to be made from payment accounts registered in the player's own name.

9. Account Suspension and Termination

oktk4 reserves the right to suspend, restrict, or close any account at any time and without prior notice if oktk4 determines, in its reasonable judgement, that the account has been used in violation of these Terms, that the account holder does not meet the eligibility requirements, or that continued operation of the account poses a risk to the integrity of the platform, other players, or any third party.

You may close your account at any time by contacting [email protected]. Upon closure, any real-money balance remaining in your account after deduction of any applicable bonus balances subject to active wagering requirements will be returned to you via your most recently used payment method, subject to identity verification. oktk4 will process closure requests within a reasonable time period.

10. Limitation of Liability

To the fullest extent permitted by applicable law, oktk4 shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or in connection with your use of the platform, including but not limited to loss of winnings, loss of data, loss of profits, or any other loss or damage of any nature, even if oktk4 has been advised of the possibility of such damages.

oktk4's total aggregate liability to any player in connection with any single claim or series of related claims shall not exceed the total amount deposited by that player into their oktk4 account in the 30-day period immediately preceding the event giving rise to the claim. This limitation applies regardless of the form of the action and regardless of whether oktk4 has been advised of the possibility of the relevant damage.

11. Privacy and Data Protection

oktk4 collects and processes personal data in accordance with its Privacy Policy, which is available at /privacy-policy and forms an integral part of these Terms. By accepting these Terms, you also acknowledge and accept the Privacy Policy. Personal data collected during the registration process and throughout your use of the platform — including your mobile number, payment method details, and transaction history — is used solely for the purposes of operating your account, processing transactions, carrying out identity verification, complying with applicable legal obligations, and improving the platform experience. oktk4 does not sell personal data to third parties.

If you do not accept the revised Terms, you must close your account. We encourage you to review these Terms periodically.
