These terms govern your use of the opkok platform. We've written them in plain language so you actually understand what you're agreeing to — no legal jargon designed to confuse. Please read through before you register or place your first bet.
You must be 18 or older and a resident eligible to use opkok. Age verification may be required at any time to protect minors and comply with platform standards.
Every game on opkok runs on independently certified RNG software. Game outcomes are random, unmanipulated, and audited regularly to ensure fairness for all players.
Deposits and withdrawals are processed only to verified accounts in your name. opkok does not accept third-party payments and will return funds that cannot be verified.
You are responsible for keeping your opkok login credentials secure. Any activity on your account is your responsibility unless you report unauthorised access promptly.
Important: By creating an account or using any part of the opkok platform, you confirm that you have read, understood, and agreed to these Terms and Conditions in full. If you do not agree, please do not use opkok.
These Terms and Conditions ("Terms") form a legally binding agreement between you ("the Player") and opkok ("the Platform", "we", "us"). By accessing, registering on, or using any part of the opkok platform — including games, payment services, promotions, and customer support — you agree to be bound by these Terms in their entirety.
These Terms apply to all users of opkok regardless of how they access the platform, whether through a desktop browser, mobile browser, or the opkok mobile app. If you are using opkok on behalf of another person, you confirm that you have the authority to bind that person to these Terms, and that both you and that person accept full responsibility for compliance.
opkok reserves the right to update or modify these Terms at any time. When changes are made, the updated Terms will be published on this page with a revised "last updated" date. Continued use of opkok after any changes constitutes your acceptance of the revised Terms. We recommend checking this page periodically so you stay informed.
To use opkok, you must meet all of the following eligibility requirements at the time of registration and at all times during your use of the platform:
Age Restriction: opkok is strictly for players aged 18 and above. If we have reason to believe a player is underage, we will suspend the account immediately and conduct a verification review. Any winnings accumulated during this period may be withheld pending investigation.
opkok may request documentation to verify your eligibility at any point. Failure to provide satisfactory verification within a reasonable timeframe may result in account suspension or closure. We take these checks seriously — not to create friction, but to protect the integrity of the platform and the safety of all players.
Each player is permitted to hold one opkok account only. Creating multiple accounts — whether under the same name, different names, or using different payment methods — is a serious breach of these Terms and will result in all associated accounts being suspended and any balances being forfeited.
When registering, you must provide accurate, complete, and up-to-date information. This includes your full legal name, date of birth, contact details, and any other information requested during the registration process. Providing false information is grounds for immediate account closure.
Security tip: Enable two-factor authentication on your opkok account for an extra layer of protection. It takes under a minute to set up and significantly reduces the risk of unauthorised access.
opkok supports deposits via bKash, Nagad, Rocket, and bank transfer. All deposits must be made from a payment account that is registered in your own name. opkok does not accept deposits from third-party accounts, and any such deposits will be returned to the source without being credited to your opkok balance.
Deposits are credited to your opkok account instantly in most cases. In rare situations where a deposit is delayed due to a payment provider issue, please contact our support team with your transaction reference and we will investigate promptly.
Note: opkok operates in Bangladeshi Taka (BDT). All balances, deposits, and withdrawals are displayed and processed in BDT. No currency conversion is applied on the platform.
opkok processes withdrawals to bKash, Nagad, Rocket, and bank accounts registered in your name. Withdrawals to third-party accounts are not permitted under any circumstances. This policy exists to protect players from fraud and to comply with financial security standards.
opkok's target withdrawal processing time is under 3 minutes for mobile wallet withdrawals (bKash, Nagad, Rocket). Bank transfer withdrawals may take longer depending on your bank's processing schedule. These timelines apply to verified accounts with no outstanding compliance checks.
Fast payouts: opkok's payment infrastructure is built specifically to handle high-volume local transfers without delays. Most withdrawals complete in under 3 minutes — that's a standard we hold ourselves to every day.
opkok offers bonuses and promotions to both new and existing players from time to time. All bonuses are subject to specific terms that will be clearly stated at the time the bonus is offered. These Terms provide the general framework that applies to all opkok bonuses unless a specific promotion states otherwise.
Wagering requirements: Always check the wagering requirements before accepting a bonus. These requirements determine how many times you need to play through the bonus amount before you can withdraw any associated winnings. The specific multiplier will be stated in each promotion.
All games available on opkok — including Lucky Dice, Color Prediction, Go Rush, Fishing, Hi-Lo, Mines, and Double Exposure Blackjack — use certified Random Number Generator (RNG) technology. This means every game outcome is independently random and cannot be predicted, manipulated, or influenced by opkok or any player.
opkok's RNG systems are independently audited on a regular basis to confirm that game outcomes meet the required standards of randomness and fairness. Players can request information about our RNG certification by contacting support.
The following actions are strictly prohibited on opkok. Engaging in any of these behaviours will result in account suspension, permanent closure, forfeiture of balances, and may be reported to relevant authorities where applicable:
Zero tolerance: opkok has a zero-tolerance policy for fraud, money laundering, and underage gambling. Accounts found to be involved in any of these activities will be permanently closed and all relevant information will be passed to the appropriate authorities.
opkok reserves the right to suspend or permanently close any account at its discretion, with or without prior notice, in the following circumstances:
If your account is suspended, you will be notified by email with the reason for suspension where it is safe and appropriate to do so. In cases involving suspected fraud or legal matters, opkok may not be able to provide detailed reasons for suspension.
Players who wish to close their own account voluntarily can do so by contacting support at [email protected]. Any remaining balance in a voluntarily closed account will be returned to your verified payment method after any outstanding wagering requirements have been assessed.
