Please read these Terms & Conditions carefully before registering an account or placing any wager on the mt661 platform. By accessing the site, you agree to be bound by the provisions set out below.
These cards summarise the most important obligations. They do not replace the full terms below — please read every clause in its entirety.
You must be at least 21 years of age and a resident of Indonesia to open an mt661 account and place real-money wagers. Age verification may be requested at any time. Accounts found to belong to underage players are closed immediately and all balances forfeited.
Each individual is permitted to hold exactly one active mt661 account. Duplicate accounts are prohibited and will result in suspension of all associated accounts. Bonus balances accumulated across multiple accounts are forfeited in their entirety upon detection.
All promotions and bonuses offered by mt661 are subject to wagering requirements and eligibility conditions detailed in the individual promotion terms. General bonus rules — including the prohibition on withdrawing bonus funds before rollover completion — are set out in Clause 7 of these Terms.
All transactions on mt661 are conducted in Indonesian Rupiah (IDR). Withdrawals are processed to the same payment method used for the most recent deposit. mt661 reserves the right to request identity verification before processing withdrawal requests above threshold amounts.
Arbitrage betting, use of automated betting software (bots), collusion, match-fixing, and any form of fraud are strictly prohibited. mt661 reserves the right to void bets, withhold winnings, and permanently close accounts where prohibited conduct is identified.
mt661 is committed to responsible gaming. Deposit limits, cooling-off periods, and self-exclusion tools are available to all players at no charge. Players who believe gambling is affecting their wellbeing are encouraged to visit the Responsible Gaming page or contact support immediately.
Important notice: These Terms & Conditions constitute a legally binding agreement between you and mt661. By creating an account, making a deposit, or placing any wager on the mt661 platform, you confirm that you have read, understood, and agree to be bound by these Terms in their entirety. If you do not agree, you must not use the mt661 platform.
For the purposes of these Terms & Conditions, the following definitions apply:
By accessing, registering on, or in any way using the mt661 platform, you confirm that you have read and understood these Terms & Conditions in their entirety and that you agree to be legally bound by them. These Terms apply to all services provided by mt661, including the Sportsbook, Casino, Slots, Virtual Sports, and Crash Game products.
These Terms are supplemented by: (a) the mt661 Privacy Policy, which governs the collection and processing of your personal data; (b) the mt661 Responsible Gaming Policy, which sets out player-protection tools and obligations; and (c) specific promotion terms attached to individual bonus offers. Where any conflict exists between a specific promotion's terms and these general Terms, the specific promotion terms shall prevail for that promotion only.
mt661 reserves the right to amend these Terms at any time in accordance with Clause 16. Continued use of the platform following notification of amendments constitutes acceptance of the revised Terms.
You must be at least 21 years of age to register an account, make a deposit, or place any wager on the mt661 platform. mt661 operates a strict zero-tolerance policy regarding underage gambling. Any account found to have been opened by or on behalf of an individual under 21 years of age will be closed immediately, all funds deposited will be returned where technically feasible, and any winnings generated will be forfeited in their entirety.
Age restriction: mt661 is strictly for players aged 21 and over. If you are under 21 years of age, you must not access, register on, or use the mt661 platform in any capacity.
The mt661 platform is designed for use by players located in Indonesia. By registering an account, you represent and warrant that: (a) you are a resident of Indonesia or are otherwise accessing the platform from a jurisdiction in which online gambling is not prohibited by applicable law; (b) you are not acting on behalf of any third party; and (c) your participation is for personal entertainment purposes only.
It is your sole responsibility to ensure that your use of the mt661 platform is lawful in your jurisdiction. mt661 accepts no liability for any breach of local law by a Player arising from their use of the platform.
The following individuals are not eligible to register or maintain an mt661 account:
To open an mt661 Account, you must provide accurate, complete, and current information at registration, including a valid email address, a chosen username, and your date of birth. You must not use false identity information or impersonate any other person during the registration process.
Each individual player is permitted to hold one (1) active mt661 Account at any time. Creating duplicate or multiple accounts — whether under the same or different personal details, email addresses, or payment methods — is strictly prohibited. Where multiple accounts are detected, mt661 reserves the right to close all associated accounts and forfeit any balances held therein. The first account created in chronological order shall be deemed the legitimate account for the purposes of any balance reinstatement consideration.
You are solely responsible for maintaining the confidentiality of your mt661 Account credentials, including your username, password, and any two-factor authentication codes. You must not share your login credentials with any third party. mt661 will never ask for your password via email, live chat, or any other communication channel. Any activity conducted through your Account using your credentials will be deemed authorised by you unless you have notified mt661 of a compromise promptly and in writing.
mt661 reserves the right to request identity verification documents — including but not limited to a government-issued photo identification (KTP, passport, or SIM) and proof of address — at any point during the account lifecycle, and in particular prior to processing any withdrawal request. Failure to provide satisfactory verification documentation within the timeframe specified by mt661 may result in temporary suspension of withdrawal functionality and, in cases of extended non-compliance, account closure.
You must promptly notify mt661 of any changes to your registered contact information, including email address and phone number. Changes to registered payment method details must be processed through the mt661 customer support team and are subject to identity re-verification.
mt661 accepts deposits via the following Indonesian payment channels: bank transfer (BCA, BRI, BNI, Mandiri, CIMB Niaga, Bank Permata, BSI); e-wallets (OVO, DANA, GoPay, ShopeePay, LinkAja). All deposits are denominated in Indonesian Rupiah (IDR). mt661 does not accept cryptocurrency, international wire transfers, or any payment method not listed as currently supported on the platform's deposit page.
The minimum deposit amount is Rp 50.000 per transaction. mt661 reserves the right to adjust minimum deposit thresholds for specific payment methods and will communicate any changes via the platform's payment information page.
Bank transfer deposits are typically credited to the Player's mt661 Account within 5–15 minutes during 08:00–22:00 WIB on business days. E-wallet deposits via OVO and DANA are credited instantly at all hours. Processing delays arising from issues at the sending bank or payment provider are outside mt661's control; Players experiencing delays beyond 30 minutes should contact the mt661 support team.
mt661 reserves the right to decline or reverse any deposit that: (a) originates from a payment method not registered in the Player's name; (b) is suspected to be associated with fraudulent activity or money laundering; or (c) is made using funds that are the proceeds of a criminal activity. mt661 complies with applicable anti-money-laundering standards and may report suspicious activity to the relevant authorities.
Deposits must originate from payment accounts held in the Player's own name. Third-party deposits are not accepted and will be returned, less any applicable processing fees charged by the payment provider.
Players may request withdrawal of their Real Money Balance at any time, subject to: (a) the Account being fully verified (KYC complete); (b) no open bonus wagering requirements remaining on the Account; and (c) the withdrawal amount meeting the applicable minimum threshold.
The minimum withdrawal amount is Rp 100.000 per transaction. There is no maximum single withdrawal amount for fully verified accounts; however, mt661 reserves the right to process large withdrawals in tranches and to request additional verification documentation for withdrawals exceeding specified thresholds.
Withdrawal requests are processed within 5–15 minutes for standard verified accounts during 08:00–22:00 WIB. OVO and DANA withdrawals are available for processing 24 hours a day, seven days a week. Withdrawal requests submitted outside of standard processing hours are queued and processed at the next available window. mt661 targets same-day settlement for all withdrawal requests received before 21:00 WIB.
Withdrawals will be returned to the same payment method used for the Player's most recent deposit, or to a pre-registered bank account or e-wallet confirmed during the KYC process. mt661 does not process withdrawals to third-party accounts or payment methods not held in the Player's own name.
mt661 reserves the right to delay processing of any withdrawal pending identity verification, source-of-funds clarification, or review of recent account activity. Players will be notified by the support team within a reasonable timeframe if additional documentation is required. Withdrawal requests subject to review will not be declined solely on the basis of the review process, provided the Player cooperates fully with document requests.
All bonuses, free bets, cashback offers, and promotional credits offered by mt661 are subject to the following general conditions unless explicitly stated otherwise in the individual promotion's specific terms:
The mt661 welcome bonus is available to new Players on their first qualifying deposit. Full terms — including minimum deposit threshold, percentage match, maximum bonus amount, and wagering requirements — are set out on the promotions page at the time of offer. The welcome bonus may not be combined with any other deposit bonus offer. Any attempt to claim the welcome bonus under multiple accounts will be treated as a terms violation under Clause 10.
mt661 actively monitors account activity for patterns indicative of bonus abuse, including but not limited to: low-margin betting designed solely to meet rollover requirements; hedged betting across multiple accounts; and systematic exploitation of promotional offers in a manner inconsistent with genuine recreational play. Where bonus abuse is detected, mt661 reserves the right to void bonus balances, void associated winnings, and close the Account.
Wagering Requirements: Bonus funds are not withdrawable until the applicable Wagering Requirement has been fully completed. Attempting to withdraw with an active bonus balance will result in the bonus and any bonus-derived winnings being forfeited before the withdrawal is processed. Players who do not wish to accept a bonus should contact support before depositing.
Bets placed through the mt661 Sportsbook are binding once confirmed by the platform. A confirmation screen is displayed prior to final bet submission; by proceeding past the confirmation step, the Player accepts the stated odds and stake as final. mt661 is not liable for bets placed in error by the Player, including incorrect stake amounts or incorrect selection of markets.
Odds offered by mt661 are subject to change until the bet is confirmed. In the event of a system error that results in clearly erroneous odds being offered — odds that a reasonable bettor would recognise as manifestly incorrect — mt661 reserves the right to void the affected bet and return the stake to the Player's Account, regardless of whether the bet has been confirmed.
mt661 may void a bet in the following circumstances: event cancellation or postponement beyond 48 hours from original scheduled kick-off; force majeure events affecting the outcome or conduct of an event; confirmed match-fixing or sporting integrity violations; or system errors resulting in clearly incorrect odds or market listings. Voided bets are settled at evens (1.00), with the stake returned to the Player's Account.
In-play bets are accepted subject to the availability of live market data. During periods of data interruption or technical delay, in-play markets may be suspended without notice. Bets accepted during such suspensions may be voided at mt661's discretion if the suspension was caused by a technical error that resulted in stale or incorrect odds being displayed.
Mix parlay (accumulator) bets combine multiple selections into a single bet with combined odds. All selections must win for the accumulator to pay out. A void selection within an accumulator is settled at odds of 1.00 for that selection only; the remaining selections continue as a reduced accumulator. Minimum and maximum accumulator leg counts are specified in the Sportsbook interface at the time of bet construction.
Each casino table game and slot title on the mt661 platform is governed by the specific rules applicable to that game, as displayed within the game interface. In the event of any conflict between in-game rules and these Terms, the in-game rules shall apply to game-specific mechanics, and these Terms shall apply to all account, payment, and conduct matters.
In the event of a technical malfunction during a Casino or Slots session — including but not limited to disconnection, display errors, or game engine failures — the outcome of any round in progress at the time of the malfunction may be voided. mt661 will endeavour to restore interrupted sessions where technically feasible but accepts no liability for losses attributable to Player-side connectivity or device issues.
All slot and RNG-based casino games on mt661 are supplied by independently audited third-party studios. Live casino tables are operated by licensed live dealer studios including Evolution Gaming, Pragmatic Play Live, and SA Gaming. mt661 does not control individual game outcomes and is not liable for variance in results consistent with the published Return-to-Player (RTP) statistics for each game.
The following activities are strictly prohibited on the mt661 platform and will result in immediate Account suspension, forfeiture of balances, and reporting to relevant authorities where applicable:
mt661 reserves the right to suspend or close any Account at its sole discretion, with or without prior notice, where: (a) a breach of these Terms has occurred or is suspected; (b) unusual or suspicious account activity is detected; (c) a regulatory or law enforcement request is received; or (d) continued operation of the Account poses a risk to the integrity of the platform or other Players.
Where an Account is closed due to a Player's breach of these Terms, mt661 reserves the right to forfeit the Account balance in its entirety, including both Real Money Balance and Bonus Balance. Where closure is initiated by mt661 for reasons unrelated to Player misconduct, the Real Money Balance will be returned to the Player via the most recent verified payment method within a reasonable timeframe.
Players may request voluntary Account closure at any time by contacting the mt661 customer support team. Prior to closure, all open bets will be settled according to their natural outcome and all pending withdrawals will be processed. Bonus balances are forfeited upon voluntary closure.
All content on the mt661 platform — including but not limited to the mt661 brand name, logo, website design, software, text, graphics, images, and audio-visual material — is the exclusive property of mt661 or its licensors and is protected by applicable intellectual property laws.

mt661 aims to maintain continuous platform availability but does not warrant that the platform will be uninterrupted, error-free, or free from technical defects. Scheduled maintenance windows will be communicated in advance where possible. mt661 accepts no liability for losses arising from platform downtime, technical errors, or interrupted betting sessions caused by circumstances outside mt661's reasonable control.
Gambling inherently involves financial risk. mt661 accepts no liability for gambling losses incurred by Players in the course of normal platform use. By accepting these Terms, you acknowledge that you are wagering at your own risk and that mt661 is not responsible for the outcome of any bet or game.
To the maximum extent permitted by applicable law, mt661's total liability to any Player in respect of any claim arising from the use of the platform — whether in contract, tort, or otherwise — is limited to the amount deposited by that Player in the 30-day period immediately preceding the claim. mt661 shall not be liable for any indirect, consequential, special, or punitive damages under any circumstances.
mt661 shall not be liable for any failure or delay in performing its obligations under these Terms where such failure or delay arises from circumstances beyond mt661's reasonable control, including but not limited to acts of God, natural disasters, civil unrest, government action, cyberattacks, telecommunications failure, or interruption of third-party payment services.
The collection, use, storage, and processing of personal data provided by Players in connection with the mt661 platform is governed by the mt661 Privacy Policy, which forms part of the agreement between you and mt661. By registering an Account, you consent to the processing of your personal data in accordance with the Privacy Policy.
mt661 does not sell personal data to third parties. Data shared with payment processors, game studios, and fraud-detection service providers is limited to that which is strictly necessary for the provision of the relevant service and is subject to appropriate data-processing agreements.
