To use mt661 services, you must meet all of the following eligibility requirements:
mt661 reserves the right to verify your identity, age, and eligibility at any time. You agree to provide accurate documentation upon request, including but not limited to a valid Indonesian ID card (KTP), proof of address, and payment method verification. Failure to provide requested documentation may result in account suspension or termination.
mt661 operates a strict 21+ age policy. All accounts are subject to mandatory age verification via Indonesian ID card (KTP) submission. Accounts found to belong to underage users will be immediately suspended, all bets voided, and funds confiscated. It is a criminal offense to provide false identification.
To access mt661 services, you must create a personal account by providing accurate and complete information including your full name, date of birth, email address, phone number, and residential address. All information provided must match the details on your official identification documents.
You may only register one account per person. Creating multiple accounts is strictly prohibited and will result in closure of all accounts and forfeiture of any balances. Each household, IP address, device, and payment method may only be associated with one account.
You are solely responsible for maintaining the confidentiality of your account login credentials (username and password). You must not share your account details with any third party. You are liable for all activity that occurs under your account, whether authorized by you or not.
You must notify mt661 immediately if you become aware of any unauthorized access to your account or any other security breach. mt661 is not liable for any loss or damage arising from your failure to protect your account credentials.
mt661 operates a comprehensive Know Your Customer (KYC) verification process. You may be required to submit the following documents before you can withdraw funds:
Verification typically takes 24-48 hours. Withdrawals may be delayed or denied if verification is incomplete or if submitted documents do not meet our requirements.
mt661 accepts deposits via various payment methods including major Indonesian banks (BCA, BRI, BNI, Mandiri, CIMB Niaga, OCBC NISP) and e-wallets (OVO, DANA, GoPay, ShopeePay, LinkAja). All deposits are processed in Indonesian Rupiah (IDR).
Minimum deposit amounts vary by payment method but typically start at Rp 50,000. Maximum deposit limits may apply based on your account status and payment method. Deposits are usually credited to your account instantly, though some methods may take up to 24 hours.
You must only deposit funds that belong to you. Deposits from third-party accounts are not permitted and may result in account suspension and confiscation of funds.
Withdrawal requests can be made at any time through your account dashboard. All withdrawals are subject to identity verification. First-time withdrawals typically require completion of the full KYC process.
Minimum withdrawal amount is Rp 100,000. Maximum withdrawal limits apply based on your account level and may be adjusted at mt661's discretion. Withdrawals are typically processed within 24 hours during business days, with most bank transfers completing in under 5 minutes.
Withdrawals must be made to a payment method registered in your own name. We reserve the right to request additional verification before processing large withdrawals or if we suspect fraudulent activity.
mt661 does not charge fees for deposits or withdrawals. However, your bank or payment provider may apply their own transaction fees. Processing times vary by payment method:
mt661 offers various bonuses and promotions to both new and existing players, including welcome bonuses, deposit bonuses, cashback offers, and loyalty rewards. All bonuses are subject to specific terms and conditions which will be clearly stated on the promotional page.
Unless otherwise stated, all bonuses are subject to wagering requirements before any winnings can be withdrawn. Typical wagering requirements range from 15x to 30x the bonus amount. Different game types contribute at different rates toward wagering requirements:
Bonuses are intended for recreational players only. Abuse of bonuses, including but not limited to creating multiple accounts, coordinated betting, or low-risk betting strategies designed solely to release bonus funds, will result in bonus forfeiture and may lead to account termination.
mt661 reserves the right to void bonuses, withhold winnings, and close accounts if we determine that bonus terms have been violated or that bonuses are being systematically exploited.
All bets must be placed through the mt661 platform. Bets are considered placed when they are confirmed on your account and a unique bet ID is generated. You are responsible for ensuring that your bets are correct before confirmation. Once a bet is confirmed, it cannot be changed or cancelled except in specific circumstances outlined in these terms.
Minimum and maximum stake limits apply to all bets and vary by sport, league, market, and account status. mt661 reserves the right to refuse or limit stakes at any time without providing a reason.
Bets are settled based on the official result as determined by the relevant governing body of the sport or event. mt661 uses reputable third-party data providers to verify results. In cases where official results are not available, we will use the result determined by our appointed results service.
If an event is abandoned, postponed, or cancelled, bets will be voided unless the event is rescheduled and completed within 48 hours of the original start time. Exceptions apply to certain sports and tournaments—consult our sport-specific rules for details.
mt661 makes every effort to ensure that all odds, lines, and prices displayed are accurate. However, errors may occasionally occur. If we identify a palpable error (obvious mistake in pricing), we reserve the right to void affected bets, even after they have been confirmed and settled.
Examples of palpable errors include but are not limited to: incorrect odds that do not reflect the true probability of the outcome, incorrect team names or event details, and technical glitches causing incorrect prices to be displayed.
mt661 offers a wide variety of casino games including slots, table games (blackjack, roulette, baccarat), live dealer games, and instant win games. Each game has its own specific rules which are available within the game interface.
All games provided by mt661 use certified Random Number Generators (RNG) that are regularly tested by independent auditing firms to ensure fairness. Game outcomes are completely random and cannot be predicted or manipulated.
Return to Player (RTP) percentages are displayed for each game and represent the theoretical return over millions of game rounds. Actual results may vary significantly in the short term. RTP does not guarantee any specific outcome or winning amount.
In the event of a game malfunction, all affected bets will be voided, and funds will be returned to your account. Game malfunctions include software errors, display errors, disconnections during gameplay, and incorrect game outcomes caused by technical issues.
If you experience a disconnection while playing a game, the game round will continue and be settled according to the game rules. You can view the outcome and settle any unresolved bets by reopening the game. For live dealer games, if you are disconnected while cards are being dealt or the wheel is spinning, standard casino rules apply and the hand will be completed without further action from you.
